Navigation is gaining popularity.

However, in a car navigation system equipped with a touch panel-type dual-screen liquid crystal, although different images and different operation input images are provided to the driver's seat and the passenger seat, since the driver's seat and the passenger seat share the input unit (operation part) of the touch panel, so it cannot be distinguished from which side the operation came from. Therefore, for example, the passenger in the passenger seat operates the touch panel to increase the volume, but it is recognized that this operation is not a volume operation but an operation to change the display format of the car navigation that the driver in the driver's seat is watching and listening to, and the driver's seat and the passenger's seat will appear. Problems such as users making involuntary movements.

Therefore, various technologies have been disclosed for distinguishing detection of an operation from the driver's seat and an operation from the passenger seat, and performing respective corresponding operations.

For example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2006-47534) discloses that currents with different frequencies are supplied from different power sources to the driver's seat and the passenger seat, and the touch panel detects the currents and determines the frequency, thereby distinguishing detection of signals from the driver. The operation of the agent or the technology of multiple operators from the operation of the assistant agent.

Further, the invention according to claim 17 is characterized in that, in the above invention, the operation control unit accepts an operation input of a restriction operation while the vehicle is running, and when the specified occupant is a passenger other than the driver, Execute the action corresponding to the above operation input.

According to the inventions of claims 1, 4, and 5, a touch panel is provided, a pulse signal with a different timing is provided to each of a plurality of operable operators, the operator who performs the operation is designated, and the operation with the designated operator is performed. The corresponding control detects the supplied pulse signal when the operator performs an operation, and performs the operator's designation according to the timing of the detected pulse signal, so that noise can be suppressed to a minimum with respect to the supplied current, As a result, the operator can be specified correctly.

For example, when using a car navigation system as an in-vehicle device, if it is assumed that the timing of the pulse signal is staggered by 0.2 seconds and provided to the driver's seat and the passenger seat, then the timing of detecting the pulse signal can be used to distinguish between operations from the driver's seat and those from the passenger seat. operation, and able to suppress the noise to a minimum, the result can correctly specify the operator.

In addition, according to the invention of claim 2, when the operator operates the hard switch, the pulse signal provided to the operator is detected by the hard switch, and the operator's designation is performed based on the timing of the detected pulse signal. Therefore, in When hard switches are further included, it is not limited to the touch panel, and the operator can be correctly specified even with hard switches.

For example, when a car navigation system is used as an in-vehicle device, when the hard switch for starting the car navigation and the hard switch for starting the TV are the same hard switch, if the hard switch is operated from the passenger seat, the TV is started, and if it is operated from the driver's seat, Then, starting a car navigation system, etc., is not limited to the touch panel, and the operator can be correctly designated even with a hard switch, and an operation corresponding to the operator can be performed. Furthermore, for example, as described above, it is possible to use the same hard switch to start TV, car navigation, etc., and to integrate hard switches with multiple functions as one hard switch. Increased number of hard switches.

In addition, according to the invention of claim 3, the electrical characteristics of the operator are detected based on the detected pulse signal, and the pulse signal provided to the operator is adjusted according to the detected electrical characteristics. Therefore, for each operator Being able to fine-tune the width and height of the pulse, the result can be more correctly specified to the operator.

For example, the width of the pulse signal can be increased or shortened according to the person who is easy to electrify and the person who is not easy to electrify. In addition, the pulse signal can be adjusted by various methods of increasing or decreasing the width of the pulse signal. Operators can be specified more correctly.

In addition, according to the invention of claim 6, when the operator operates the input device, the pulse signal provided is sampled a plurality of times through the input device, and the operator's designation is made based on the sampling result. Therefore, it is possible to consider The operator is specified on the basis of the noise with respect to the supplied current, and as a result, false detection can be prevented, and the operator can further be specified correctly.

For example, in the sampled pulse signal, when the timing pulse signal provided to the driver seat occupant, the timing pulse signal provided to the passenger seat occupant, it is considered that both parties have operated or the pulse signals provided to the two parties overlap When the pulse signal of the timing is affected by noise, etc. and does not belong to any of the timing pulse signals, the operator can be specified using various conditions. As a result, misoperation can be prevented, and further, it can be specified correctly operator.

In addition, according to the invention of claim 7, the operator's electrical characteristics are detected based on the pulse signal detected by the input device, and the sensitivity of at least one of the input device and the operator designating device is changed according to the detected electrical characteristics, Therefore, it is possible to detect the pulse signal with the optimal reception sensitivity for each operator, and as a result, it is possible to prevent the operator from misdesignating.

For example, if a pulse signal passing through a large person and a pulse signal passing through a small person are detected with the same sensitivity, the pulse signal passing through a large person is more difficult to detect than a small person. Therefore, erroneous detections such as missing a pulse signal of a person with a large body may occur. Therefore, by using the present invention, when detecting a large person, the sensitivity of at least one of the input device and the operator designation device is changed to a higher sensitivity than a small person. In this way, a pulse signal passing through a large person and a pulse signal passing through a small person can be detected at the same level, and as a result, erroneous designation by the operator can be prevented.

In addition, according to the invention of claim 8, when the operator operates the input device, an operation signal indicating that the input unit is operated by the operator is further detected together with a pulse signal passed by the operator, and the timing of detecting the pulse signal is compared. When the timing differs from the timing of detecting the operation signal, the level of the pulse signal provided to the operator is adjusted so that the timing coincides. Therefore, the optimum detection level of the detection pulse signal can be maintained, and as a result, it can be firmly To prevent false detection of pulse signals.

For example, when the timing of detecting the pulse signal is longer than the timing of detecting the operation signal, adjustments are made in the direction of increasing the level of the supplied pulse signal so that the timings of both are consistent; When the timing is long, the adjustment is made in the direction of reducing the level of the supplied pulse signal so that the timings of both are consistent. As a result, the optimum detection level of the detection pulse signal can always be maintained.

In addition, according to the invention of claim 9, when the operator operates the input device, an operation signal indicating that the input device is operated by the operator is detected together with a pulse signal detected by the operator, and based on the range of timing at which the operation signal is detected, Within the level of the pulse signal by the operator, adjust at least one of the detection threshold of the pulse signal detected by the operator and the level of the pulse signal provided to the operator, so that the optimal level and detection threshold can be used for detection The pulse signal, as a result, can more securely prevent false detection of the pulse signal.

For example, the in-vehicle system maintains a sufficiently detectable time for detecting the pulse signal relative to the timing for detecting the operation signal, but when the detection time margin is small, the detection threshold is lowered to lower the level of the pulse signal output to the seat sensor. The direction is adjusted, and the timing of detecting the pulse signal becomes the same detection waveform as the timing of detecting the operation signal. In addition, although the detection time of the in-vehicle system has a large margin, when the timing of detecting the pulse signal is insufficient compared with the timing of detecting the operation signal, the detection threshold is increased, and further, the level of the pulse signal output to the seat sensor is increased. The direction is adjusted, and the timing of detecting the pulse signal becomes the same detection waveform as the timing of detecting the operation signal.

In addition, according to the invention of claim 10, pulse signals with different timings are provided to the occupants of the vehicle, the occupant as the operator is designated, and the control corresponding to the operation of the designated operator is performed. When the supplied pulse signal is detected, and the operator is specified based on the timing of the detected pulse signal, the noise relative to the supplied current can be suppressed to a minimum, and as a result, the operator can be correctly specified.

In addition, according to the invention of claim 11 , when an operation related to the driving of the vehicle is designated by an occupant other than the driver, the operation is not accepted, so it is possible to prevent the occupant other than the driver from participating in the driving operation.

For example, as described in claim 12, it is possible to prevent a passenger other than the driver from performing transmission operation, parking brake operation, siren operation, vehicle lamp operation, windshield wiper operation, defogging operation, and the like.

In addition, according to the invention of claim 13, the operation of the centralized management operation on the vehicle body equipment is accepted only when the occupant designated as the operator who has the authority to execute the operation is accepted, and therefore, it is possible to prevent the occupant who does not have the authority to perform the operation. Centralized management of vehicle body equipment.

For example, as shown in claim 14, for the centralized door lock operation of simultaneously controlling the locking mechanism of multiple doors, the centralized window control of simultaneously controlling the opening and closing of multiple windows, and the lock control operation of prohibiting the opening and closing operation of specified doors etc., only authorized crew members can execute it.

Furthermore, according to the invention of claim 15 , when the occupant of each seat performs an individual operation on the individually operable vehicle body equipment, the operator of the operation is designated to determine which seat the individual operation corresponds to. Therefore, it is possible to prevent erroneous actions of the occupants of other seats, and to achieve miniaturization of the interface by sharing the interface for individual actions.

For example, as described in claim 16, it is possible to prevent malfunctions and achieve common use of interfaces for the operation of the air conditioner in the car cabin, the operation of changing the state of the seats, the operation of opening and closing the windows, and the like.

In addition, according to the invention of claim 17 , even if the operation input of the restriction operation during traveling is performed by an operation from a passenger other than the driver, it can be executed.

Detailed ways

Embodiments of the display system, operator specifying method, vehicle-mounted display system, and operation control system of the present invention will be described in detail below with reference to the accompanying drawings. In addition, the main terms used in this embodiment, the outline and features of the vehicle-mounted device of this embodiment, the configuration and processing flow of the vehicle-mounted device will be sequentially described below, and finally various modifications to the embodiment will be described.

[Example 1]

[explanation of term]

First, main terms used in this embodiment will be described. The so-called "vehicle system" used in this embodiment (corresponding to "display system", "operator designation method", and "vehicle display system" described in the scope of claims) is a computer such as a car navigation system installed in a vehicle. The system, specifically, displays car navigation and television (TV) and the like on a liquid crystal monitor and the like, and accepts various operations through a touch panel and a remote controller and the like. In such an "in-vehicle system" such as a car navigation system, either the car navigation or the TV is displayed on the liquid crystal monitor, and the setting of the destination or switching of the display format is accepted from the touch panel of the liquid crystal monitor during the car navigation. And perform, in addition, perform channel switching, volume adjustment, etc. while on TV. In addition, in the case of a dual-screen liquid crystal that displays different images on the driver's seat and the passenger seat, generally, the "vehicle system" displays two images on the screen, but it can also be used in common for various operations. Touch panels or switches, etc.

However, the recent car navigation system ("vehicle system") is not only TV and navigation, but also can insert DVD, connect digital camera, etc., to reduce the driver's driving burden and provide comfortable driving. Comfort also offers a variety of services. Therefore, a car navigation system equipped with a dual-screen liquid crystal displaying different images on the driver's seat and the passenger seat (including the rear seat) can provide services suitable for the driver and fellow passengers, respectively. A more comfortable car navigation system for fellow passengers. In addition, although the operation of the remote control was the main thing in the past, the burden on the user is reduced by the operation using the touch panel. In addition, in this embodiment, although the case of distinguishing between the operation of the passenger in the driver's seat and the operation of the passenger in the passenger seat is described, the present invention is not limited to this, and the operation of the passenger in the driver's seat may be distinguished from the operation of the passenger in the passenger seat. The operation from the passenger of the front passenger seat and the operation from the passenger of the rear seat. In addition, in this embodiment, although the case where the present invention is installed as an in-vehicle system has been described, the present invention is not limited thereto, and can be applied to all cases where two-screen liquid crystals or multi-screen liquid crystals such as televisions are used, for example.

[Overview and features of in-vehicle systems]

The outline and features of the in-vehicle system of Embodiment 1 will be described below using FIG. 1 . FIG. 1 is a system configuration diagram showing the overall configuration of an in-vehicle system according to the first embodiment.

As shown in Figure 1, the vehicle-mounted system is equipped with seat sensors on the driver's seat and the passenger seat, and provides pulse signals (such as current, etc.) The driver provides a pulse signal. Then, the vehicle-mounted system includes: a pulse signal supply unit that supplies pulse signals, a control unit that performs various controls, a touch panel that accepts operations from the operator, dual monitors that display images, etc. Equipped with seat sensor.

Based on such a configuration, the in-vehicle system of the first embodiment mainly specifies the operator who operates the touch panel as described above, and is particularly characterized by being able to accurately specify the operator.

If this main feature is specifically described, when the seat sensor detects that someone is seated, the vehicle-mounted system supplies pulse signals with different timings from the pulse signal supply unit to a plurality of operators who can operate the touch panel (see (1) in FIG. 1 . ) and (2)). As a specific example, when the seat sensor (driver's seat) and the seat sensor (passenger seat) detect that there are people sitting on the driver's seat and the passenger seat, the pulse signal supply unit of the in-vehicle system responds to multiple operations on the touch panel. Or provide current, and provide different timing pulse signals (pulse signal A (current A) and pulse signal B (current B)) to each seat sensor in various ways, for example, pulse signals with different pulse periods or pulse amplitudes and rising edges wait.

Then, when the operator operates the touch panel, the vehicle-mounted system detects the pulse signal provided to the operator by the pulse signal supply unit through the touch panel, and performs the operator's designation according to the timing of the detected pulse signal (see ( 3) and (4)). In the above example, when the control unit of the vehicle-mounted system operates the touch panel, the pulse signal A (current A) supplied to the seat sensor (driver's seat) passes through the driver's body, The pulse signal A (current A) is transmitted from the touch panel to the pulse signal supply unit and detected. Then, the control unit of the in-vehicle system determines that the operator who operated the touch panel is the driver sitting in the driver's seat from the timing of the detected pulse signal.

In this case, the in-vehicle system executes the operation content suitable for the determined operator. For example, if it is assumed that the operation on the touch panel is an operation to switch the display of the car navigation of the dual display when it is from the driver's seat occupant, and an operation to increase the volume of the TV when it is from the passenger seat occupant, then the control unit of the in-vehicle system will When it is determined that the operator is the driver's seat occupant, an operation to switch the display of the navigation on the dual monitor is performed. On the other hand, when it is determined that the operator is the passenger seat, the control unit of the in-vehicle system performs an operation to increase the volume.

In this way, the in-vehicle system of Embodiment 1 can minimize noise relative to the pulse signal (such as current, etc.) supplied to the operator when differentially detecting operations from a plurality of operators, and as a result, the above-mentioned main feature , the operator can be specified correctly.

[Configuration of in-vehicle system]

Next, the configuration of the in-vehicle system shown in FIG. 1 will be described using FIG. 2 . FIG. 2 is a block diagram showing the configuration of the in-vehicle system of the first embodiment. As shown in FIG. 2 , the vehicle-mounted system includes a seat sensor 10 , a seat sensor 11 , a touch panel display 15 , a pulse signal supply unit 20 and a control unit 30 .

The seat sensor 10 detects that a person is seated on the driver's seat, and supplies a pulse signal (current) supplied from a pulse signal supply unit 20 described later to the seated driver. As a specific example, when a person is seated on the driver's seat, the seat sensor 10 notifies a signal indicating that a person is seated to the pulse signal supply part 20 described later, and a pulse signal is provided from the pulse signal supply part 20 to the driver. A (current A).

The seat sensor 11 detects that someone is seated on the passenger seat, and supplies a pulse signal (current) supplied from a pulse signal supply unit 20 described later to a fellow passenger (passenger seat passenger) who is seated. As a specific example, like the seat sensor 10, the seat sensor 11 will notify the pulse signal supply unit 20 described later to indicate that it is detected that someone is seated when someone is seated on the sub-seat seat, and the pulse signal supply unit 20 will receive a signal from the pulse signal supply unit. 20 Provide a pulse signal B (current B) to fellow passengers (passengers in the passenger seat). In addition, in the present embodiment, although the case where the seat sensor is provided on the driver's seat and the passenger seat has been described, the present invention is not limited thereto, and furthermore, it may be provided on the rear seat or the like.

Touch-panel display 15 is configured to overlap touch-panel 16 and dual display 17 to display and output various images, moving images, and the like. Touch-panel 16 is an input unit that receives various operations input from an operator. In addition, the touch-panel display 15 corresponds to the "input device" described in the scope of claims.

The touch panel 16 includes a matrix switch and a resistive film switch, etc., by pressing the position corresponding to the display on the dual display 17, indicating the operation of equipment such as car navigation, and receiving a pulse signal (current) during operation, and turning the The pulse signal is output to an input device of the pulse signal supply unit 20 described later. As specifically described in the above-mentioned example, when the touch panel 16 receives various operations from the driver's seat, it outputs the contents of the operation (operation position) to the control unit 30 described later, and receives information from the seat sensor through the driver's body. The pulse signal A (current A) supplied from 10 is output to a pulse signal supply unit 20 described later, a signal in which the pulse signal A (current A) is superimposed on a signal indicating the operation position.

The pulse signal supply part 20 includes a logic OR substrate 21 and a control substrate 22, and provides pulse signals (currents) with different timings to a plurality of operators operating the touch panel 16, and according to the pulse signals (currents) provided and detected to the operators, ) detects the electrical characteristics of the operator, and adjusts the pulse signal supplied to the operator based on the detected electrical characteristics so that the operator can be easily specified by the control unit 30 described later. In addition, the pulse signal supply unit 20 corresponds to the "pulse signal supply device" described in the claims.

If it is specifically described in the above-mentioned example, when the logic or substrate 21 of the pulse signal supply part 20 receives a signal indicating that someone is seated on the seat from the seat sensor 10 or the seat sensor 11, as shown in FIG. The current output from the control unit 30 described above is converted into a pulse signal A (current A) and a pulse signal B (current B) with different rising edge timings, and is supplied to the driver's seat and the passenger seat where the passenger who can operate the touch panel is seated, respectively. . Specifically, the logic or board 21 provides the pulse signal A (current A) (refer to (1) of FIG. B (current B) (see (2) in FIG. 3 ) is supplied to the seat sensor 11 of the passenger seat. In addition, although pulse signals with different rising edges have been described here, the present invention is not limited thereto. For example, pulses with different pulse periods or pulse widths may be provided. In addition, FIG. 3 is a diagram showing an example of pulse signals with different timings supplied from the pulse signal supply unit.

The control board 22 supplies current to each seat sensor via the logic OR board 21, and outputs a signal in which a pulse signal (current) is superimposed on a signal indicating an operation position received from the touch panel 16 to the control unit 30 described later. The supplied and detected pulse signal (current) detects the electrical characteristics of the operator, and adjusts the pulse signal of the current supplied to the operator based on the detected electrical characteristics so that the operator can be easily specified by the control unit 30 described later. As specifically described in the above example, when the control board 22 receives an operation of the driver's seat from the touch panel 16 , it outputs a pulse signal A passed by the driver's seat occupant to the control unit 30 described later.

In addition, when the control board 22 receives an operation of the driver's seat from the touch panel 16, it judges whether the operator's electrical characteristics are easily energizable based on a pulse signal provided by the driver. This pulse signal A (current A) is adjusted and supplied.

On the other hand, if it is determined that energization is difficult, the control board 22 adjusts the supplied pulse signal so that detection is easy. For example, as shown in FIG. 4 , the control board 22 adjusts the pulse of the pulse signal (current A) supplied after the time T compared with the time t0 at which the supply is started, so that the pulse signal (current A) at which the electrical characteristics are determined (adjusted) After) the pulse height of the subsequent pulse signal A (current A) increases (see (1) in FIG. 4 ), and the pulse width increases (see (2) in FIG. 4 ). In addition, the control board 22 corresponds to the "adjustment device" described in the claims. In addition, FIG. 4 is a diagram showing an example of adjustment of a pulse signal.

The control section 30 has an internal memory for storing a control program such as an OS (operating system), a program specifying various processing procedures, etc., and required data, and in particular, as a part closely related to the present invention, includes an operator-specified The unit 31 and the operation execution unit 32 execute various processing.

When the operator operates the touch panel 16, the operator specification unit 31 detects the pulse signal (current) supplied to the operator by the pulse signal supply unit 20 through the touch panel 16 and the control board 32, and ) is specified by the operator. As specifically described in the above-mentioned example, when the driver in the driver's seat operates the touch panel 16, the operator specifying unit 31 transmits the pulse signal A through the pulse signal supply unit 20 based on a signal in which the pulse signal A is superimposed on the signal indicating the operation position. The control board 22 of the control board 22 detects the pulse signal A (current A) provided to the operator by the pulse signal supply part 20, specifies the operator as the driver according to the timing of the pulse signal A (current A), and from the signal indicating the operation position A signal indicating the operation content of the designated operator is output to the operation execution unit 32 described later. In addition, the operator specifying unit 31 corresponds to the "operator specifying means" described in the claims.

When an operator is specified, the operation executing unit 32 executes the operation content suitable for the operator, or outputs an instruction to execute the operation content to a device corresponding to the operation content. As a specific example, when the operation of increasing the volume of the TV and the operation of switching the display of the car navigation are at the same operation position on the touch panel, the operation execution unit 32 is designated by the operator designation unit 31 when the input is from the driver’s seat. When an operation signal from the passenger seat is input, the display of the car navigation is switched, or the corresponding device is executed, and when a signal designated as an operation from the passenger seat is input, the volume of the TV is increased, or the corresponding device is executed. In addition, the operation of increasing the volume of the TV and the operation of switching the display of the car navigation described here are merely examples, and various operations such as air conditioning can be performed. In addition, the operation execution unit 32 corresponds to the "operation control device" described in the scope of the claims.

[handling of in-vehicle system]

Next, the processing of the in-vehicle system will be described using FIG. 5 . 5 is a flowchart showing the flow of operator designation processing in the in-vehicle system of the first embodiment.

(Flow of operator designation processing)

As shown in Figure 5, when detecting that someone is seated on the seat by the seat sensor 10 or the seat sensor 11 (step S501 is affirmative), the pulse signal supply part 20 provides a pulse signal (current ) (step S502).

As a specific example, when a person is seated on the driver's seat and the passenger seat, the seat sensor 10 and the seat sensor 11 detect that a person is seated, and output a signal indicating this to the pulse signal supply unit 20 . Then, upon receiving the signal, pulse signal supply unit 20 supplies pulse signals (current A and current B) with different timings to seat sensor 10 of the driver's seat and seat sensor 11 of the passenger seat (see FIG. 3 ).

Then, when the pulse signal (current) superimposed on the signal indicating the operation position from the touch panel 16 is detected by the control board 22 (Yes in step S503), the operator specifying section of the control section 30 31 designates the operator based on the detected timing of the pulse signal (current) (step S504), and the operation execution unit 32 executes the operation content based on the signal indicating the operation position and the designated operator (step S505).

If it is specifically described in the above-mentioned example, when the operation of increasing the volume of the TV and the operation of switching the display of the car navigation are on the same operation position on the touch panel 16, when the driver in the driver's seat accepts on the touch panel 16 During the operation, the operator specifying unit 31 detects the pulse signal from the signal indicating the operation position on which the pulse signal (current) passing through the driver's seat is superimposed through the control board 22, and specifies the operator based on the timing of the detected pulse signal (current). The driver is the driver's seat, and outputs a signal indicating that to the operation execution unit 32 , and outputs a signal indicating the operation position to the operation execution unit 32 . In this case, the operation executing unit 32 executes switching of the display of the car navigation corresponding to the driver's operation, or causes the corresponding device to execute the display.

On the other hand, when it is determined by the operator specifying unit 31 that the operator is the passenger of the passenger seat, the operation executing unit 32 increases the volume of the TV corresponding to the passenger of the passenger seat, or causes the corresponding device to perform the operation.

(Flow of pulse adjustment processing)

Next, pulse adjustment processing in the vehicle-mounted system will be described using FIG. 6 . 6 is a flowchart showing the flow of pulse adjustment processing in the in-vehicle system of the first embodiment.

As shown in FIG. 6 , when a pulse signal (current) is detected by the touch panel 16 from a signal in which a pulse signal is superimposed on a signal representing an operation position (Yes in step S601), the pulse signal supply unit 20 responds to The pulse signal (current) detected by the operator specifying unit 31 flowing through the touch panel detects the electrical characteristics of the operator (step S602 ).

As a concrete example, when the touch panel 16 is operated from the driver's seat, the operator specifying unit 31 detects that the pulse signal (current) passing through the control board 22 superimposed on the signal indicating the operation position from the touch panel 16 is pulse signal A (current A), and outputs a signal indicating that the detected pulse signal is the pulse signal A (current A) to the pulse signal supply unit 20 . Then, the pulse signal supply unit 20 that receives the signal detects whether the operator (driver) has electrical characteristics that make it difficult to conduct electricity, based on the pulse signal (current A).

Next, the pulse signal supply unit 20 adjusts the pulse of the provided pulse signal (current) according to the detected electrical characteristics (step S603), and provides the adjusted pulse signal (current) to the corresponding seat sensor (step S604) .

As specifically described in the above-mentioned example, when the pulse signal supply unit 20 detects from the pulse signal A (current A) that the operator (driver) has an electrical characteristic that is difficult to energize, the pulse signal supply unit 20 provides Various methods such as adjusting the pulse signal (current) of the pulse signal (current) and increasing the height of the pulse signal are used to provide the adjusted pulse signal (current) to the seat sensor 10 of the driver's seat.

[Effect of Embodiment 1]

In this way, according to Embodiment 1, the touch panel 16 is provided, a pulse signal with a different timing is provided to each of a plurality of operable operators, the operator who performs the operation is designated, and the operation corresponding to the designated operator is performed. When the operator performs an operation, the provided pulse signal is detected, and the operator's designation is made based on the timing of the detected pulse signal, so noise can be suppressed to the minimum relative to the provided pulse signal (current) Limits, as a result, can be correctly specified by the operator.

For example, when using a car navigation system as an in-vehicle device, if the timing of the pulse signal is staggered by 0.2 seconds and provided to the driver's seat and the passenger seat, the timing of detecting the pulse can be used to distinguish between operations from the driver's seat and operations from the passenger seat, and Noise is suppressed to a minimum, and as a result, operators can be specified correctly.

In addition, if Embodiment 1 is adopted, the operator's electrical characteristics are detected based on the detected pulse signal, and the pulse signal provided to the operator is adjusted according to the detected electrical characteristic, therefore, for the operator, fine adjustments can be made individually. The pulse width or height, as a result, can further be specified correctly by the operator.

For example, the pulse can be adjusted in various ways such as increasing or shortening the width of the pulse or raising or lowering the height of the pulse according to the person who is difficult to energize or the person who is easy to energize. As a result, it is possible to further accurately specify the operator .

In addition, in Embodiment 1, although it is configured to provide a pulse signal to the seat sensor that detects that someone is seated when it is detected that someone is seated on the seat, the present invention is not limited to this, because only the driver's seat and the passenger seat The operator needs to be designated only when people are seated on both sides of the seat. Therefore, it is also possible to provide a pulse signal when it is detected that people are seated on both the driver's seat and the passenger seat.

In addition, in Embodiment 1, although the case where it is suitable for two monitors was demonstrated, this invention is not limited to this, It can also apply to the case where the driver's seat and the passenger seat view the same image. For example, by designating an operator, it is not only necessary to accept operations performed by the driver during travel.

In addition, in Embodiment 1, although a signal in which a pulse signal is superimposed on a signal indicating the operation position is input to the control board, and a signal in which a pulse signal is superimposed on the signal indicating the operation position is output to the control unit Explain, but the present invention is not limited thereto, and the signal and pulse signal representing the operation position can also be input to the respective control boards, and the signal and pulse signal representing the operation position can be respectively output to the control part. The position signal is directly input to the control unit without passing through the control board.

In addition, the pulse adjustment process of Embodiment 1 can be performed all the time due to changes in human electrical characteristics caused by the environment, and can also be adjusted initially by outputting a display prompting to touch the touch panel to the display when the in-vehicle system is operating. Further, although the pulse adjustment process of Embodiment 1 detects the electrical characteristics of the person with the pulse signal supply part, and performs the adjustment of the pulse signal, it may also use the control part to detect the electrical characteristics according to the pulse signal input by the operator. , adjust the current output from the control unit, and adjust the pulse signal, and the pulse signal can also be adjusted based on the operator's body shape prediction described later.

[Example 2]

However, in Embodiment 1, the case where the pulse signal (current) supplied to the operator is detected by the touch panel has been described, but the present invention is not limited thereto, and detection by a hard switch is also possible.

Therefore, in Example 2, the case where the pulse signal (current) supplied to an operator is detected by a hard switch is demonstrated using FIG.7 and FIG.8. First, the configuration of the in-vehicle system of the second embodiment will be described using FIG. 7 . In addition, FIG. 7 is a diagram showing the configuration of the in-vehicle system of the second embodiment.

[Configuration of Vehicle-mounted System (Embodiment 2)]

As shown in Figure 7, like embodiment 1, the vehicle-mounted system of embodiment 2 comprises: the seat sensor that is equipped on driver's seat and passenger seat; Provide the logic of pulse signal (current) or substrate, control substrate; Carry out various control The control unit; the touch panel that accepts operations from the operator and the dual monitors that display images and the like.

Then, the difference from Embodiment 1 is that it includes: hard switches (SW(1)~SW(3)), SW sensors (1)~SW sensors (3) equipped on the hard switches, and the respective SW The control board (1) to the control board (3) where the sensor is connected to the SW.

Regarding the configurations different from the above-mentioned Embodiment 1, if they are respectively specifically described, SW (1) to SW (3) are input units for operating car navigation systems such as car navigation and TV, and are used to detect directions when the operator operates. The pulse signal (current) provided by the operator is the pulse signal (current) transmitted through the operator's body, and the pulse signal (current) is output to the control board (1) ~ control board (3) in the car navigation Hard switch used for power supply and starting of TV etc.

The SW sensors (1) to SW sensors (3) output the pulse signal (current) provided to the operator who operates the SW sensors (1) to SW sensors (3) to the control board (1) to the control board connected through the shield. Substrate (3).

The control board ( 1 ) to ( 3 ) have the same functions as the control board 22 described in the first embodiment. For example, the control board (1) to the control board (3) input a pulse signal (current) passed by the operator through the SW sensor (1) to the SW sensor (3). In addition, the control board (1) to the control board (3) receive operations from the driver's seat occupant and the passenger's passenger seat from the SW sensor (1) to the SW sensor (3) or SW (1) to SW (3) At this time, the electric characteristic of the operator is detected according to the pulse signal (current) provided by the driver and the passenger of the passenger seat, and the pulse signal provided to the corresponding seat sensor is adjusted according to the characteristic. However, it is different from the first embodiment in that ON/OFF signals and pulse signals (current) of SW(1) to SW(3) are separately input and that only the pulse signal (current) is output to the control unit.

Based on this configuration, when the seat sensor detects that someone is seated on the seat, the pulse signal supply unit of the vehicle-mounted system supplies a pulse signal (current) with a different timing to each of a plurality of operators who can operate each SW (refer to (1) and (2) of Figure 7). Specifically, when it is detected by the seat sensor (driver's seat) and the seat sensor (passenger seat) that there are people sitting on the driver's seat and the passenger seat respectively, the pulse signal supply part of the vehicle-mounted system can operate SW(1)～ Multiple operators of SW (3) provide pulse signals (current), and pulse signal A (current A) and pulse signal B (current B) with different timings are provided to each seat sensor.

Then, when the operator operates the SW, the control unit of the in-vehicle system detects the pulse signal (current) supplied to the operator by the pulse signal supply unit through the SW sensor, and designates the operator based on the timing of the detected pulse signal (current). (Refer to (3) and (4) of FIG. 7). As specifically described in the above example, when the driver in the driver's seat operates the SW (1), the control unit of the in-vehicle system passes the pulse signal A (current A) supplied to the seat sensor (driver's seat) through the driver's The body is supplied from the SW sensor (1) through the control substrate (1), and the ON signal of the SW (1) is supplied to the control substrate (1). Then, the in-vehicle system control unit judges that the pulse signal (current A) is pulse signal A (current A) based on the timing of the supplied pulse signal (current), and judges that the operator who operated SW (1) is a driver seated on the driver's seat.

In this way, if the vehicle-mounted system of Embodiment 2 is adopted, when the operator operates the hard switch, the pulse signal (current) provided to the operator is detected by the SW sensor provided on the hard switch, and according to the detected pulse signal Since the operator is specified at regular intervals, when a hard switch is further provided as the input unit, the operator can be accurately specified even with the hard switch, not limited to the touch panel.

[Configuration of Hard Switch (Embodiment 2)]

The configuration of the hard switch shown in FIG. 7 will be described below using FIG. 8 . FIG. 8 is a diagram for explaining the overall configuration of a hard switch.

As shown in FIG. 8 , the hard switches (SW ( 1 ) to SW ( 3 )) include a SW portion 82 , a detection electrode 83 (SW sensor), and a Pt plate 84 . The case 81 is a box for accommodating electronic equipment such as a SW portion 82 and a Pt plate 84 constituting the SW. Specifically, the case 81 is fixed to an in-vehicle system, a vehicle body, etc., and is used to fix these electronic devices so that the electronic devices such as the SW portion 82 and the Pt plate 84 do not come off.

The SW unit 82 includes a detection electrode 83 for detecting a pulse signal (current) flowing through the operator, and is set at a certain distance from the Pt plate 84 . Specifically, when the SW portion 82 is in a pressed shape, it protrudes slightly from the housing 81 and is easily pressed by the operator. In addition, it may also be in the shape of an On/Off switch. For example, the SW portion 82 When pressed by the operator, the SW contact becomes conductive (ON).

The detection electrode 83 is an electrode for detecting a pulse signal (current) flowing through the operator. Specifically, the detection electrode 83 detects the pulse signal A (current A) provided to the driver by the driver when the driver operates the SW, and sends the pulse signal A (current A) to the corresponding control board.

The Pt board 84 is a plate-shaped or film-shaped printed circuit board on which electronic components such as integrated circuits, resistors, and capacitors are mounted, and wiring that connects these components to form an electronic circuit is formed. Specifically, the Pt plate 84 is configured as a circuit that outputs a signal indicating the ON/OFF state of the SW contact to the corresponding control board, and when the operator presses the SW portion 82, outputs a signal indicating the ON state of the SW contact.

[Processing of in-vehicle system (Embodiment 2)]

Next, the processing of the in-vehicle system will be described using FIG. 9 . 9 is a flowchart showing the flow of hard switch operator designation processing in the in-vehicle system of the second embodiment.

(Flow of hard switch operator specification processing)

As shown in Figure 9, when it is detected by the seat sensor (driver's seat) or the seat sensor (passenger seat) that someone is sitting on the seat (step S901 is affirmative), the pulse signal supply part detects that the person has taken a seat The sensor provides a pulse signal (current) (step S902).

As a specific example, when someone is seated on the driver's seat and the passenger seat, the seat sensor (driver's seat) and the seat sensor (passenger seat) detect that someone is seated, and outputs a signal indicating that to the pulse signal supply unit . Then, upon receiving the signal, the pulse signal supply unit supplies pulse signals (current A and current B) with different timings to the seat sensor of the driver's seat (driver's seat) and the seat sensor of the passenger's seat (passenger seat).

Then, when the ON signals from SW (1) to SW (3) are detected through the control board (1) to the control board (3) (Yes in step S903), the control part will 3) Designate the operator at the timing of the detected pulse signal (current) (step S904), and perform processing corresponding to the operated SW and the operation content according to the designated operator, or cause the corresponding device to execute (step S905) .

If specifically described in the above example, the operation of increasing the volume of the image (such as TV, etc.) watched and listened to by the occupant of the passenger seat and the display of the image (such as the image of car navigation, etc.) watched and listened to by the driver are switched. When the operation is the same hard switch (SW1), when the driver on the driver's seat accepts the operation with the hard switch (SW1), the control unit detects the pulse signal passing the driver through the control board (1), and according to the detected pulse signal The timing designates the operator as the driver of the driver's seat, outputs a signal indicating that, and outputs a signal indicating that the operated hard switch is SW1. In this case, the control unit switches the display of the car navigation system according to the driver's operation, or causes the corresponding device to switch.

On the other hand, when it is determined by the control unit that the operator is the passenger of the passenger seat, the control unit executes the volume up of the TV corresponding to the operation of the passenger of the passenger seat, or executes the corresponding device.

(Flow of hard switching pulse adjustment processing)

Next, the pulse adjustment processing of the in-vehicle system will be described using FIG. 10 . 10 is a flowchart showing the flow of pulse adjustment processing of hard switches in the in-vehicle system of the second embodiment.

As shown in Fig. 10, when a pulse signal is detected by the hard switch (SW sensor) (step S1001 affirmative), the pulse signal supply part detects the operator's pulse signal (current) according to the detected pulse signal (current) passing through the operator and flowing through the hard switch. Electrical characteristics (step S1002).

As a specific example, when the SW (1) is operated from the driver's seat, the control unit detects that the pulse signal (current) passing through the control board (1) is the pulse signal A (current A), and will indicate the detected pulse The signal (current) is the pulse signal A (current A) and is output to the pulse signal supply unit. Then, the pulse signal supply unit that receives this signal detects whether or not the operator (driver) has electrical characteristics that make it difficult to energize based on the pulse signal A (current A).

Next, the pulse signal supply unit adjusts the supplied pulse signal (current) according to the detected electrical characteristics (step S1003), and supplies the adjusted pulse signal (current) to the corresponding seat sensor (step S1004).

As specifically described in the above example, when the pulse signal supply unit detects from the pulse signal A (current A) that the electrical characteristics of the operator (driver) are difficult to energize, the pulse signal supply unit increases the supplied current Various methods such as adjusting the pulse signal (current) of the pulse signal (current), increasing the pulse height, etc., and providing the adjusted pulse signal (current) to the seat sensor (driver's seat) of the driver's seat.

[Effect of Embodiment 2]

In this way, if the embodiment 2 is adopted, when the operator operates the hard switch, the pulse signal provided to the operator is detected by the hard switch, and the operator's designation is performed according to the timing of the detected pulse signal. Therefore, it is not limited to touch panel, the operator can be assigned correctly even in hard switches.

For example, when using a car navigation device as an in-vehicle device, if the hard switch to start the car navigation and the hard switch to start the TV are the same hard switch, if the hard switch is operated from the passenger seat, the TV will be started, and if the hard switch is operated from the driver's seat, the TV will be started. Car navigation, etc. are not limited to touch panels, and operators can be correctly specified even in hard switches, and operations corresponding to the operator can be performed. Further, for example, as mentioned above, the same hard switch can be used to start TV and car navigation, etc., and the hard switch with multiple functions can be integrated as one hard switch. The number of hard switches.

In addition, in Embodiment 2, as in Embodiment 1, when it is detected that a person is seated on the seat, a pulse signal is provided to the seat sensor that detects that a person is seated, but the present invention is not limited thereto. Since the operator needs to be designated only when both the driver's seat and the passenger seat are seated, it is also possible to provide a pulse signal when it is detected that persons are seated on the driver's seat and the passenger seat.

In addition, in Embodiment 2, although the case where it is applied to dual monitors is described, the present invention is not limited thereto, and may be applied to a case where the same image is viewed on the driver's seat and the passenger seat. For example, by specifying the operator, it is possible to accept not only the driver's operation during driving.

In addition, in Embodiment 2, although the pulse signal and the ON signal of SW are input to the control board, and the pulse signal is output to the control part from the control board which inputs the ON signal, the present invention is not limited to this, It is also possible to input a signal in which a pulse signal is superimposed on the ON signal of the SW, and output only the pulse signal or a signal superimposed on the ON signal. In addition, the ON signal may be directly input to the control unit without passing through the control board.

In addition, the pulse adjustment process of the second embodiment can be performed all the time due to changes in human electrical characteristics due to the environment, and can also be adjusted initially by outputting a display prompting to touch the touch panel to the display when the in-vehicle system is operating. Further, the pulse adjustment process of embodiment 2 is the same as that of embodiment 1. Although the pulse signal supply part is used to detect the electrical characteristics of the person and adjust the pulse signal, it can also be used according to the pulse signal input by the operator. The control unit detects electrical characteristics and adjusts the current output from the control unit to adjust the pulse signal. The pulse signal may also be adjusted based on the body shape prediction of the operator to be described later.

[Example 3]

However, in Embodiments 1 and 2, when the operator operates an input unit such as a touch panel or a hard switch, the case where a pulse signal is detected by the input unit and designated by the operator is described, the present invention does not Limiting to this, it is also possible to perform multiple samplings through the input unit, and specify by the operator based on the sampling results.

Therefore, in Embodiment 3, using FIGS. 11 to 13, when the operator operates the input unit, the pulse signal provided to the operator is sampled multiple times through the input unit, and the sampled pulse signal satisfies the prescribed The condition will be described for the case where the requirement is specified by the operator. In addition, since the configuration is the same as that of Embodiment 1 or Embodiment 2, description thereof will be omitted.

For example, in the vehicle-mounted system of the third embodiment, when the operator operates the input unit once, pulse signal sampling is performed 15 times by the input unit. Then, the 15 sampled pulse signals include: "the timed pulse signal provided to the occupant of the driver's seat", "the timed pulse signal provided to the occupant of the passenger seat", "it is considered that both parties have operated or It is considered a pulse signal at a timing where the pulse signals supplied to both sides overlap", and "a pulse signal at a timing that does not belong to either timing due to the influence of noise or the like". In addition, although the case of sampling 15 times has been described here, the number of times of sampling is not limited, and sampling may be performed 20 times. In addition, the pulse signal is supplied to the seat sensor at a cycle that can be sampled 15 times even in one operation (short press).

Then, the in-vehicle system performs the operator's designation on the condition that the pulse signal sampled 15 times in this way satisfies a predetermined condition. Therefore, the predetermined conditions ( FIGS. 11 to 13 ) used by the in-vehicle system to designate the operator of the pulse signal to be sampled 15 times will be described.

FIG. 11 is a diagram illustrating an example of conditions specifying an operator based on a sampled pulse signal. In this vehicle-mounted system, as described above, when the operator operates the input unit, the pulse signal provided by the operator is sampled 15 times through the input unit. Then, among the pulse signals sampled 15 times by the vehicle-mounted system, as shown in FIG. The information signal of the occupant of the seat", that is, "the timing pulse signal provided to the occupant of the passenger seat", is designated by the designated operator.

As a specific example, the vehicle-mounted system, as shown in Figure 11, when "the signal of the information of the occupant in the driver's seat is greater than or equal to 8 times" in the pulse signal that has been sampled 15 times, that is, "the information provided to the occupant in the driver's seat" When the timing pulse signal is detected 8 times or greater than 8 times", the operator is designated as a "passenger in the driver's seat" (refer to 1 in FIG. 11 ). In addition, when the in-vehicle system has performed 15 samples of pulse signals, "signals with passenger information of the passenger seat are greater than or equal to 8 times", that is, "the timing pulse signal provided to the passenger of the passenger seat is detected 8 times or more. 8 times", the operator is designated as the "passenger of the passenger seat" (refer to 2 in FIG. 11 ). In addition, the in-vehicle system detects that “the timing of the pulse signal provided to the driver’s occupant is less than 8 times” among the pulse signals sampled 15 times. When the number of times is less than 8 times and the timing pulse signal provided to the occupant of the passenger seat is detected less than 8 times", it is designated as "no operator" (refer to 3 in FIG. 11 ).

In the in-vehicle system of Embodiment 3, the conditions for specifying by the operator are not limited to the conditions shown in FIG. 11 , and further detailed conditions may be set and used as shown in FIG. 12 . In addition, FIG. 12 is a diagram showing an example of specifying an operator's condition based on a sampled pulse signal. The difference between Fig. 12 and Fig. 11 is that in addition to "the signal of the information of the occupant with the driver's seat" and the "signal of the information of the occupant with the passenger seat", the "passenger with the driver's seat and the passenger with the passenger seat information signal", that is, "a timed pulse signal that is considered to be operated by both parties or is considered to overlap with the pulse signals provided to both parties", specifying whether the operator is "the passenger of the driver's seat" or "the passenger of the passenger seat" or " Neither side."

Here, if only the difference between the condition specified by the operator shown in FIG. 12 and that in FIG. 11 is described, when the vehicle-mounted system samples the pulse signal 15 times, as shown in 3 of FIG. 12 , "Signals with information about both the driver's seat occupant and the front passenger's occupant", that is, "a pulse signal at a timing that is believed to have been operated by both parties or at a time when the pulse signals provided to both parties are considered to overlap" is detected more often than "with When a signal without operator information, that is, a pulse signal of a timing affected by noise or the like and not belonging to any timing is detected many times, the operator is designated by "prioritizing the operation of the driver's seat occupant".

In this case, the in-vehicle system detects more "signals with information on both the driver's seat occupant and the front passenger's occupant" than "signals with no operator information" among the pulse signals sampled 15 times. At that time, further, if the total of "signals with information on the driver's seat occupant is equal to or greater than 8 times" and "signals with information on both the driver's seat occupant and the passenger seat occupant" is "10 times or greater", specify The operator is specified as "the driver's seat occupant" (refer to 3-1 in FIG. 12 ), and if it is "less than 10 times", it is specified as "no operator" (refer to 3-2 in FIG. 12 ).

On the other hand, when the "signal with information on both the driver's occupant and the front passenger's occupant" is detected more often than "the signal with no operator's information" among the pulse signals sampled 15 times , designate the operator by "prioritizing the operation of the passenger of the passenger seat". In this case, the in-vehicle system detects more "signals with information on both the driver's seat occupant and the front passenger's occupant" than "signals with no operator information" among the pulse signals sampled 15 times. At that time, further, if the sum of the "signals with passenger information on the passenger seat is equal to or greater than 8 times" and "signals with information from both the passenger seat on the driver's seat and the passenger seat on the passenger seat" is "10 times or greater" , the designated operator is designated as "passenger of the passenger seat" (refer to 3-3 in Figure 12), and if it is "less than 10 times", then designated as "no operator" (refer to 3-4 in Figure 12).

In addition, when the "signal with information on both the driver's seat occupant and the passenger's passenger seat" is detected less frequently than the "signal with information on no operator", the in-vehicle system designates "no operator" (refer to 4) of Figure 12. In addition, as mentioned above, which one of the information is given priority can also be determined in advance by the user, etc., and since the possibility of continuous operation is high, it is also possible to give priority to the operator specified in the previous operation, or to Priority is given to the passenger in the front passenger seat while driving.

In addition, the on-board system can also assign operators based on the most detected signals. Therefore, a case where the in-vehicle system designates an operator based on the most detected signal will be described using FIG. 13 . FIG. 13 is a diagram illustrating an example of specifying an operator's condition based on a sampled pulse signal.

As shown in FIG. 13 , the in-vehicle system designates the operator as the “passenger in the driver’s seat” when “the signal of the passenger’s information on the driver’s seat is the most” among the pulse signals sampled 15 times (refer to 1 in FIG. 13 ). , when "the passenger with the passenger seat has the most information signals", the designated operator is "the passenger of the passenger seat" (refer to 2 in FIG. 13 ).

Then, the in-vehicle system gives priority to the operation of the driver's seat occupant or the operation of the passenger's passenger seat, and specifies the operator (refer to FIG. 3). Specifically, when giving priority to the operation of the driver's seat occupant, the in-vehicle system "signals of both information of the driver's seat occupant and the passenger of the passenger seat are the most" and "signals of the information of the driver's occupant" and " When the sum of the signals of both the driver's seat occupant and the passenger seat's information is "10 times or more", the designated operator is "the driver's seat occupant" (refer to 3-1 in Figure 13), if "Less than 10 times" is designated as "no operator" (refer to 3-2 in FIG. 13 ).

On the other hand, when giving priority to the operation of the passenger of the passenger seat, the in-vehicle system has the most signals of information of both the passenger of the driver's seat and the passenger of the passenger seat, and "signals of the information of the passenger of the passenger seat" and When the sum of the "signals of both the information of the driver's passenger and the passenger of the passenger seat" is "10 times or more", the designated operator is the "passenger of the passenger seat" (refer to 3-3 in Fig. 13), if If it is "less than 10 times", it is designated as "no operator" (refer to 3-4 in FIG. 13 ).

Then, when "the signal with no operator's information is the most", the vehicle-mounted system calculates the number of "passenger with driver's seat information" by removing "signal with no operator's information" from the pulse signals sampled 15 times. Signal", "Signal with Passenger Passenger Information", "Signal with Passenger Seat Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Seat Passenger Passenger Passenger Seat Passenger Passenger Passenger Seat Passenger Passenger Passenger Passenger Passenger Passenger Seat Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger Passenger ).

Specifically, when the in-vehicle system has "the signal with the most information about no operator" among the pulse signals that have been sampled 15 times, if the next detected signal with the most number of times is "the information about the occupant with the driver's seat" If it is a "signal with information about the passenger of the passenger seat", the specified operator is "the passenger of the passenger seat" (Refer to 4-2 of FIG. 13).

Then, when the in-vehicle system "has the most signal with no operator information" among the pulse signals sampled 15 times, if the next detected signal with the most number of times is "the passenger with the driver's seat and the passenger with the passenger seat" The signal of the information of both occupants" designates the operator by prioritizing the operation of the occupant of the driver's seat or the operation of the occupant of the passenger seat (refer to 4-3 of FIG. 13 ).

When prioritizing the operation of the occupant in the driver's seat, the in-vehicle system has "the signal with the most information about no operator" among the pulse signals sampled 15 times, and the signal with the most detected number of times next is "the signal with the information of the driver's seat". When the signal of both the information of the passenger and the passenger of the passenger seat", if the total of the "signal of the information of the passenger with the driver's seat" and "the signal of the information of both the passenger of the driver's seat and the passenger of the passenger seat" is "More than or equal to 10 times", the designated operator is "the occupant of the driver's seat" (refer to 4-3-1 of Figure 13), if it is "less than 10 times", then designated as "no operator" (refer to Figure 13 4-3-2).

On the other hand, when prioritizing the operation of the passenger of the passenger seat, the in-vehicle system "has the most signal with no operator information" among the pulse signals sampled 15 times, and the next detected signal is In the case of "a signal having information on both the driver's seat occupant and the passenger seat on the front passenger seat", if the "signal having information on the passenger seat on the passenger seat" and "the signal having information on both the driver's seat occupant and the passenger " is "more than or equal to 10 times", then the designated operator is "passenger seat passenger" (refer to 4-3-3 in Figure 13), if it is "less than 10 times", then designated as "no operator" (Refer to 4-3-4 of Fig. 13).

In this way, according to Embodiment 3, when the operator operates the input unit, the pulse signal provided is sampled multiple times through the input unit, and the operator designates the pulse signal on the condition that the sampled pulse signal satisfies a predetermined condition. Therefore, the operator can be specified in consideration of the noise of the supplied pulse signal, and as a result, false detection can be prevented, and the operator can be specified more accurately.

For example, when the sampled pulse signal includes: the timing pulse signal provided to the occupant of the driver seat, the timing pulse signal provided to the passenger of the passenger seat, the pulse signal that is considered to be operated by both parties or is considered to be provided to both In the case of pulse signals at timings where signals overlap, or pulse signals at timings that do not belong to any of the timings affected by noise, etc., the operator can be specified using any of various conditions. As a result, false detection can be prevented, and further accurate Specify the operator. In addition, information including various data and parameters shown in FIGS. 11 to 13 can be changed arbitrarily unless otherwise specified. In addition, as mentioned above, which one of the information is given priority can be determined in advance by the user, etc., and since the possibility of continuous operation is high, it is also possible to give priority to the operator specified in the previous operation. Medium gives priority to the passenger in the front passenger seat.

[Example 4]

However, in Embodiments 1 to 3, although the case where the operator operates an input unit such as a touch panel or a hard switch is described in which a pulse signal is detected by the input unit and designated by the operator is performed, when the operator operates the After touching an input unit such as a touch panel or a hard switch and detecting that the input unit is activated (ON), it is also possible to detect a pulse signal through the input unit and carry out the operator's designation.

Specifically, as shown in FIG. 14 , the vehicle-mounted system detects a pulse signal (state 1 in FIG. 14 ) through the body of the operator when the operator intends to operate the input unit and put his finger close to the switch (such as a touch panel or a hard switch, etc.). However, the pulse signal detected in this state is ignored or discarded, and the operator's designation starts based on the detected pulse signal after the input unit actually turns ON (state 2 in FIG. 14 ). In addition, FIG. 14 is a diagram for explaining a pulse signal detection state. In addition, since the configuration is the same as that of Embodiment 1 or Embodiment 2, description thereof will be omitted.

Taking the hard switch as an example, the vehicle-mounted system detects a pulse signal through the body of the operator when the operator approaches the hard switch with his finger to operate the input unit as shown in FIG. 15 . However, the onboard system discards pulse signals detected in this state. Then, the in-vehicle system, as shown in FIG. 16 , detects that the operator actually presses the switch, and starts designation by the operator based on the pulse signal detected after this state. In addition, as a method of detecting that the operator has actually pressed the hard switch, it is possible to detect using a known method such as signal detection by an electric circuit. In addition, FIG. 15 is a diagram for explaining the state before the operator presses the hard switch in order to operate the input unit, and FIG. 16 is a diagram for explaining the state where the operator presses the hard switch.

In this way, if Embodiment 4 is adopted, then the pulse signal detected when the operator is about to operate the touch panel or the hard switch and the finger is approached or touched is discarded, and the pulse signal is detected according to when the operator actually presses the touch panel or the hard switch. Therefore, it can be discarded when, for example, the occupant in the driver's seat puts his fingers close to the touch panel or the hard switch in order to explain the operation to the occupant in the passenger seat, or when his clothes touch the As a result of detecting the pulse signal in the case of touching the panel or hard switch, it is possible to prevent false detection and further correctly specify the operator. In addition, in Embodiments 1 to 3, the pulse signal is supplied to the seat sensor when it is detected that a person is seated on the seat, but when the operator actually presses the touch panel or the hard switch, the pulse signal is supplied to the seat sensor, The same effect can also be obtained. Further, as shown in the third embodiment, when the operator actually presses the touch panel or the hard switch, the same effect can be obtained by supplying a predetermined number of pulse signals to the seat sensor.

[Example 5]

However, in general, there are many cases where the conductivity of the human body differs depending on the operator. Therefore, the vehicle-mounted system of the present invention can also calculate the operator's conductance according to the detected pulse signal, and when the calculated conductance is low, at least one of the input unit, the pulse signal supply unit, and the operator specifying unit Sensitivity changed to a higher sensitivity.

As a specific example, the vehicle-mounted system of Embodiment 5, as shown in Figure 17, maintains the threshold value of conductivity in advance, and calculates the operator's conductivity according to the detected pulse signal, and when the calculated conductivity is low, it will input The sensitivity of at least one of the unit, the pulse signal supply unit, and the operator designation unit is changed to high sensitivity. Thereby, the pulse signal can be detected with the reception sensitivity optimal for each operator, and as a result, it is possible to prevent the operator from misdesignating. In addition, FIG. 17 is a diagram showing an example of a pulse signal detected when the sensitivity is changed. In addition, since it is the same as that of Example 1 and Example 2 about a structure, description is abbreviate|omitted.

In addition, the in-vehicle system does not directly detect the conductivity from the pulse signal, but can predict the conductivity based on other main factors and change the sensitivity. Specifically, the in-vehicle system can predict the body shape of the operator based on the withdrawn amount of the seat belt, the accuracy of the seat, and the front and rear positions, and change the sensitivity according to the predicted body shape.

For example, when the amount of withdrawal of the seat belt is small or the position of the front and rear of the seat is more forward, the in-vehicle system predicts that the installation area with the seat sensor is small due to the small size of the operator seated on the seat. , change the Sensitivity to Up (higher sensitivity). Also, when the seat belt on the passenger seat side is not pulled out, the in-vehicle system discards the pulse signal even if it detects the information of the passenger on the passenger seat, and designates the passenger on the driver's seat as the operator.

In this way, the sensitivity can be changed according to the physique of the driver's seat occupant or the passenger's passenger seat, etc., according to key factors such as the conductance and the amount of withdrawal of the seat belt other than the conductance, and can be specified by the operator.

[Example 6]

However, in the vehicle-mounted system of the present invention, when the operator operates the input unit, it is also possible to detect a pulse signal passed by the operator, and further detect an operation signal indicating that the input unit has been operated by the operator (for example, the operation position of the touch panel). signal or the ON signal of the hard switch, etc.), and adjust the level of the pulse signal supplied to the seat sensor.

Therefore, in Embodiment 6, a case will be described using FIGS. 18 to 21 : when the operator operates the input unit, a pulse signal passed by the operator is detected, and a pulse signal indicating that the input unit is operated by the operator is further detected. operation signal, and compare the timing of detecting the pulse signal passed by the operator (operator-designated interval: for example, the interval of sampling the above-mentioned pulse signal 15 times) and the timing of detecting the operation signal (SW ON interval), when the timing is not At the same time, the level of the pulse signal supplied to the seat sensor is adjusted so that the timing is consistent. In addition, since the configuration is the same as that of Embodiment 1 and Embodiment 2, description thereof will be omitted.

As shown in Figure 18, when comparing the pulse signal detection state and the SW state (e.g., hard switch, etc.), as the detection condition, it can be said that the ON interval (B) of the SW and the operator-specified interval (A) of the pulse signal are more the same. The more accurate the pulse signal can be detected, and the larger the detection margin (C), the easier it is to detect. In addition, the so-called detection level is the level of the pulse signal detected by the human body from the seat sensor, and the so-called ON signal of the SW is the signal detected when the operator's finger approaches or touches the SW. In addition, FIG. 18 is a diagram for comparing the pulse signal detection state and the SW state.

However, depending on the operator's respective conductivity, etc., as shown in Fig. 19, the operator-designated section (A) appears for a shorter time than the SW ON section (B), and the detection margin (C) is also limited. small case. When this state occurs, it means that the level of the pulse signal detected from the seat sensor through the human body is weak. Therefore, the in-vehicle system of Embodiment 6 is adjusted in the direction of increasing the level of the pulse signal supplied to the seat sensor so that the timing of detecting the pulse signal (the operator-designated section) and the timing of detecting the operation signal (the ON section of the SW) are adjusted. ) consistent. In addition, FIG. 19 is a diagram showing an example when the level of the detected pulse signal is weak.

Also, as shown in FIG. 20 , the operator-designated section (A) may take longer than the SW ON section (B), and the detection margin (C) may also be large. When this state occurs, it means that the level of the pulse signal detected from the seat sensor through the human body is strong. Therefore, the in-vehicle system adjusts to reduce the level of the pulse signal supplied to the seat sensor so that the timing of detecting the pulse signal (operator designated section) and the timing of detecting the operation signal (SW ON section) coincide. In addition, FIG. 20 is a diagram showing an example when the level of the detected pulse signal is strong.

Then, as described above, the timing for changing the level of the pulse signal supplied to the seat sensor may be performed periodically, and the frequency may be performed arbitrarily. In addition, as in Embodiments 1 and 2, when the in-vehicle system is in operation, adjustments can also be made initially by displaying a display prompting to touch the touch panel on the display. Therefore, a flow chart for adjusting the level of the pulse signal supplied to the seat sensor so that the timing of detecting the pulse signal (SW ON section) and the timing of detecting the operation signal (the section designated by the operator) will be described below using FIG. 21 .

21 is a flowchart showing the flow of processing for adjusting the level of a pulse signal supplied to a seat sensor in the in-vehicle system of the sixth embodiment. As shown in FIG. 21, when a pulse signal is detected by a SW (such as a touch panel or a hard switch, etc.) (Yes in step S2101), the vehicle-mounted system determines the timing of detecting the operation signal (the ON section (B) of the SW) and the detection of the pulse signal. Whether the timing (the operator-specified section (A)) is equal (step S2102).

Next, when the ON interval (B) of the SW is not equal to the operator-designated interval (A) (step S2101 is negative), the vehicle-mounted system determines whether the ON interval (B) of the SW is larger than the operator-designated interval (A) (step S2103 ).

Then, when the ON interval (B) of the SW is larger than the operator designated interval (A) (step S2103 affirmative), the vehicle-mounted system adjusts to the direction of increasing the level of the pulse signal provided (step S2104), so that The timing of detecting the pulse signal (the operator-designated section) and the timing of detecting the operation signal (the ON section of the SW) match (step S2104).

On the other hand, when the ON interval (B) of the SW is smaller than the operator designated interval (A) (step S2103 is negative), the vehicle-mounted system adjusts to the direction of reducing the level of the pulse signal provided, so that the detection pulse signal The timing of (the interval specified by the operator) and the timing of detecting the operation signal (the ON interval of the SW) match (step S2105).

Then, after the level of the supplied pulse signal is adjusted in this way, the process returns to step S2102, and the above-mentioned processing is periodically executed.

In this way, when the operator operates the input unit, the vehicle-mounted system of Embodiment 6 further detects an operation signal indicating that the input unit is operated by the operator together with the pulse signal passed by the operator, and compares the timing of the detected pulse signal with the detected operation signal. When the timing is different, the level of the pulse signal supplied to the seat sensor is adjusted so that the timing coincides. Therefore, the optimum detection level of the detection pulse signal can be maintained, and as a result, the pulse signal can be firmly prevented. False detection.

For example, when the timing of detecting a pulse signal (the operator-designated section) is shorter than the timing of detecting the operation signal (the ON section of the SW), the in-vehicle system adjusts to increase the level of the pulse signal supplied to the seat sensor. The timing of detecting the pulse signal (interval designated by the operator) and the timing of detecting the operation signal (the ON interval of the SW) are matched. In addition, when the timing of detecting the pulse signal is longer than the timing of detecting the operation signal, the in-vehicle system can adjust in the direction of reducing the level of the pulse signal supplied to the seat sensor so that the timing of detecting the pulse signal and the timing of detecting the operation signal are equal to each other. The timing is consistent, and as a result, the optimum detection level of the detection pulse signal can always be maintained.

In addition, it is also possible to adjust the voltage of the pulse signal supplied to the seat sensor using the timing of detecting the pulse signal (the operator-designated section), the timing of detecting the operation signal (the ON section of the SW), and the detection margin (C) other than the timing. flat. For example, the on-board system can also keep the "threshold value" of the detection margin in advance. When detecting a pulse signal, compare the detection margin (C) and the "threshold value" at the time of detection, and when the detection margin (C) is smaller than the "threshold value", The adjustment is made to increase the level of the pulse signal supplied to the seat sensor, and is adjusted to decrease the level of the pulse signal supplied to the seat sensor when the detection margin (C) is larger than the threshold.

In addition, the method of adjusting the level based on the timing of detecting the above-mentioned pulse signal (the operator-designated section) and the timing of detecting the operation signal (the ON section of the SW) may be combined with the method of adjusting the level based on the detection margin (C). use. For example, it is also possible to adjust the level of the pulse signal according to the detection margin (C) several times after turning on the power to the system, and then adjust the pulse signal level according to the timing of the detection pulse signal (the interval specified by the operator) and the timing of the detection operation signal (the ON of the SW). section) to adjust the level of the pulse signal. In addition, thresholds can also be preset in the timing of detecting pulse signals (interval specified by the operator) and the detection margin (C), and the difference from the respective thresholds is calculated every time detection is performed, and only when the difference is greater than or equal to a certain value, the above adjustment method is implemented. In addition, the order of adjustment is not limited to this, and may be reversed.

In addition, the level of the pulse signal adjusted in this way is stored in advance for each operator, and can be read out by the user at the time of use. For example, the levels of "father", "mother", "brother" and each operator are stored, and the user can read his own level when in use.

[Example 7]

However, in Embodiment 6, although the adjustment of the voltage of the supplied pulse signal when the timing of detecting the pulse signal (the operator-designated section of the detected pulse signal) and the timing of detecting the operation signal (the ON section of the SW) do not match Although the flat example has been described, the present invention is not limited thereto, and the operator specifying unit may be used to adjust the detection threshold of the pulse signal minimum necessary to specify the operator, and to adjust the level of the pulse signal supplied to the seat sensor. , so that it becomes greater than or equal to the adjusted detection threshold.

Therefore, in this seventh embodiment, an example will be described using FIGS. 22 to 26. When adjusting the level of the pulse signal supplied to the seat sensor, within the range of the detection timing of the operation signal, the operator specifying unit is used to adjust the A detection threshold of the pulse signal minimum required by the operator is specified, and the level of the pulse signal supplied to the seat sensor is adjusted so that it becomes equal to or greater than the adjusted detection threshold. In addition, since the configuration is the same as that of Embodiment 1 or Embodiment 2, description thereof will be omitted.

For example, as shown in FIG. 22 , although the operator-designated section (A) of the detected pulse signal maintains a time sufficient for detection with respect to the ON section (B) of the SW, due to the detection margin of the detected pulse signal (C ) is low, therefore, when only the level to the seat sensor described in Embodiment 6 is changed, the same detection waveform as that of the ON section (B) of the SW cannot be used.

Therefore, in this case, as shown in FIG. 23 , the in-vehicle system of Embodiment 7 lowers the detection threshold and adjusts in the direction of lowering the level of the pulse signal output to the seat sensor so that the detected pulse signal The operator-designated section (A) becomes the same detection waveform as the SW ON section (B). In addition, FIG. 22 is a diagram showing an example when the detection margin of the pulse signal is low, and FIG. 23 is a diagram showing an example of adjusting the level of the pulse signal by lowering the detection threshold.

In addition, as shown in FIG. 24, although the detection margin (C) is high, when the operator-designated interval (A) of the detected pulse signal is insufficient for the ON interval (B) of the SW, the vehicle-mounted The system, as shown in Figure 25, increases the detection threshold, and further adjusts to the direction of increasing the level of the pulse signal output to the seat sensor, so that the operator-designated interval (A) of the detected pulse signal becomes the same as The detection waveform is the same as the ON section (B) of SW. In addition, FIG. 24 is a diagram showing an example when the detection margin of the pulse signal is high, and FIG. 25 is a diagram showing an example of adjusting the level of the pulse signal while increasing the detection threshold.

Hereinafter, the flow of processing for adjusting the detection threshold and the level of the pulse signal described above will be described using FIG. 26 . 26 is a flowchart showing the flow of processing for adjusting the detection threshold and the level of a pulse signal in the in-vehicle system of the seventh embodiment.

As shown in Figure 26, when a pulse signal is detected by a SW (such as a touch panel or a hard switch, etc.) (step S2601 is affirmative), the vehicle-mounted system determines the timing of detecting the operation signal (the ON section (B) of the SW) and the timing of detecting the pulse signal. Whether the timing (the operator-designated section (A) of the detected pulse signal) is equal (step S2602).

Next, when the ON interval (B) of the SW is not equal to the operator-designated interval (A) of the detected pulse signal (step S2602 is negative), the vehicle-mounted system determines whether the operator-designated interval (A) is greater than the ON interval (A) of the SW ( B) is large and the detection threshold is larger than the detection margin (C) (step S2603).

Then, when the operator-specified section (A) is larger than the SW ON section (B) and the detection threshold is larger than the detection margin (C) (step S2603 affirmative), the vehicle-mounted system lowers the detection threshold (step S2604), further, Adjustment is made to lower the level of the pulse signal output to the seat sensor (step S2605).

On the other hand, when the operator-designated section (A) is smaller than the ON section (B) of the SW or the detection threshold is smaller than the detection margin (C) (step S2603 is negative), the vehicle-mounted system determines whether the ON section (B) of the SW is smaller than the ON section (B) of the SW. The operator specifies that the section (A) is large and that the detection threshold is larger than the detection margin (C) (step S2606).

Then, when the ON section (B) of the SW is larger than the operator-designated section (A) and the detection threshold is larger than the detection margin (C) (step S2606 affirmative), the vehicle-mounted system increases the voltage of the pulse signal output to the seat sensor. Adjust in the flat direction (step S2607).

On the other hand, when the SW ON interval (B) is smaller than the operator designated interval (A) or the detection threshold is smaller than the detection margin (C) (step S2606 is negative), the on-vehicle system determines whether the SW ON interval (B) is smaller than The operator specifies that the interval (A) is large and the detection threshold is smaller than the detection margin (C) (step S2608).

Then, when the SW ON section (B) is larger than the operator specified section (A) and the detection threshold is smaller than the detection margin (C) (step S2608 affirmative), the vehicle-mounted system increases the detection threshold (step S2609), further, to Adjustment is made in the direction of increasing the level of the pulse signal output to the seat sensor (step S2610).

On the other hand, when the ON section (B) of the SW is smaller than the operator-designated section (A) or the detection threshold is larger than the detection margin (C) (step S2608 is negative), the vehicle-mounted system will reduce the pulse signal output to the seat sensor. The direction of the level is adjusted (step S2611).

Then, when the in-vehicle system detects the pulse signal by the SW (Yes in step S2601), the above-mentioned processing of steps S2602 to S2611 is repeated.

In this way, if Embodiment 7 is adopted, when adjusting the level of the pulse signal provided to the seat sensor, within the range of the timing of detecting the operation signal, adjust the detection threshold of the pulse signal minimum necessary for specifying the operator, and adjust The level of the pulse signal supplied to the seat sensor is equal to or greater than the adjusted detection threshold, so that the pulse signal can be detected using the optimum level and detection threshold, and as a result, false detection of the pulse signal can be more firmly prevented .

For example, although the operator-designated section (A) of the vehicle-mounted system maintains a sufficient detection time relative to the ON section (B) of the SW, when the detection margin (C) is low, the detection threshold is lowered, and the detection threshold is lowered toward the seat sensor. The direction of the level of the output pulse signal is adjusted so that the operator-designated section (A) becomes the same detection waveform as the SW ON section (B). In addition, although the detection margin (C) is high, the operation If the specified section (A) is insufficient for the ON section (B) of the SW, the detection threshold is increased, and further, the adjustment is made in the direction of increasing the level of the pulse signal output to the seat sensor so that the operator specifies the section ( A) It becomes the same detection waveform as SW ON section (B). In addition, although the adjustment of both the detection threshold of the pulse signal and the level of the pulse signal supplied to the seat sensor has been described, it is not necessary to perform both adjustments, and only one of them may be used for adjustment.

[Example 8]

Next, a specific example of an in-vehicle operation control system using an operator's designation will be described. FIG. 27 is a schematic configuration diagram illustrating a schematic configuration of an in-vehicle device designated by an operator. In the vehicle-mounted device 100 shown in the same figure, the physical operation mechanism 110 is connected to the pulse signal supply part 20 and the control part 30, and the control part 30 is connected to the navigation unit 121, the audio unit 122, the vehicle operating system 123, the vehicle body equipment The operating system 124 is connected.

Here, the so-called physical operation mechanism 110 is any one of gear lever or parking brake operation mechanism, blinker switch, operation part of siren, hard switch for window operation, hard switch for door lock operation, operation part of seat posture adjustment device, etc. operating device.

As with the touch-panel display 15, a sensor may be provided in such a physical operation device 110 to designate which seat occupant is the operator by detecting a pulse signal.

The navigation unit 121 is a device for setting and guiding a driving route of the vehicle, and providing information such as road conditions and surrounding facilities. In addition, the audio unit 122 is a device that performs broadcast reception such as television or radio, reproduction of content stored in CD, DVD, HDD, and the like.

The driving operating system 123 is a group of in-vehicle devices that accept and execute operations related to driving. Specifically, as shown in FIG. Operation of lighting systems such as headlights and side lights, operation of windshield wipers, operation of defogging to remove fog from windows, operations related to ETC, etc. In addition, the release operation of the VSC for preventing the vehicle from slipping, the operation of the overdrive, and the like are also included in the driving operation.

The vehicle body equipment operating system 124 is a device that controls vehicle equipment such as a door locking mechanism and a window opening and closing mechanism. These equipment serve as the individual control device 132, and the occupant of each seat can individually control the in-vehicle equipment corresponding to his/her own seat. Then, the centralized management device 131 is a device that provides a function of simultaneously controlling individual in-vehicle equipment corresponding to a plurality of seats.

Specifically, as shown in FIG. 28 , as individual controls, there are air-conditioning operations near each seat, changes in the seat posture such as adjusting the front and rear positions of the seats, the inclination angle of the backrest, and the height of the seat surface, and operation of seat heaters installed on the seats. Window operation, door lock operation, door opening and closing operation, etc.

Centralized management includes centralized door locks that lock/unlock multiple doors at the same time, centralized window locks that prohibit the opening and closing of each window at the same time, and so-called child locks that prohibit the opening and closing of specified doors.

In the in-vehicle device 100 , the control unit 30 controls the operation of the navigation unit 121 , the audio unit 122 , the driving operating system 123 , and the vehicle body equipment operating system 124 using the result of operator designation by the operator designating unit 31 .

Specifically, as shown in FIG. 29 , when a driving operation is detected, if the operator is designated as the driver, the operation is accepted and executed, but if the operator is designated as a passenger other than the driver, the operation is performed by not Accepting this operation prevents the driving operation of the occupants other than the driver.

In addition, here, when it is not possible to designate whether or not the operator is a driver, the driving operation is accepted and executed. This is because when the actual operator is the driver, if the driver does not accept the driving operation, it will affect the proper running of the vehicle.

In the following, for centralized management of vehicle body equipment, if the operator is specified as the driver, the operation is accepted and executed, but when the operator is specified as a passenger other than the driver, or when the operator is unknown, by This operation is not accepted to prevent the driving operation of the occupants other than the driver.

For this centralized management, the reason why the operation is not accepted when the operator is unknown is that the centralized management of the vehicle body equipment rarely causes problems in the running of the vehicle even if it is assumed that the operation is not performed by the driver. Furthermore, desired states can be achieved by individual control.

Here, although the centralized management authority is given only to the driver, the centralized management authority may be given to occupants of any seat other than the driver's seat, and the driver may not be given the centralized management authority.

For the individual control of the vehicle body equipment, an individual operation corresponding to the seat of the operator designated by the operator designating unit 31 is executed. For example, when the driver's seat occupant performs the window opening operation, the window of the driver's seat door is opened, and when the passenger's seat occupant performs the window opening operation, the window of the passenger's door is opened. The same can be done for the rear seats.

For individual operations, there are cases where an operation device is assigned to each seat and cases where an operation device is shared among a plurality of seats. When an operation device is assigned to each seat, it is desirable to be able to perform the operation even if the operator is unknown. On the other hand, when the operating device is shared by a plurality of seats, since the operator does not know which seat should perform the control, the operation is not accepted.

Hereinafter, for the navigation unit 121 and the audio unit 122, if the driver performs complicated operations or viewing images (videos) during driving, it may have a negative impact on safe driving, so some functions are restricted during driving. .

However, for occupants other than the driver, there is no influence on driving even if complex operations or image appreciation are performed. Therefore, as shown in FIG. The object operations also accept operations. At this time, when the operator is unknown, it is desirable not to accept the operation in consideration of the possibility of the driver's operation.

Next, a specific example of operation control performed by the control unit 30 will be described with reference to FIG. 31 . Display display D1 and display display D2 shown in the same figure are examples of screens displayed on touch-panel display 15 .

On the monitor display D1 , operation buttons corresponding to the passenger seat posture operation and window opening and closing operation, and operation buttons corresponding to the driver's seat window opening and closing operation are displayed.

If the touch panel detects that the passenger's operation on the seat posture of the passenger seat or touches the operation button corresponding to the window opening and closing operation, corresponding control is executed. Likewise, if it is detected that the driver's seat occupant has touched the operation button corresponding to the opening and closing of the window, the corresponding control is executed.

However, when the front passenger operates the window opening and closing button of the driver's seat or when the driver's seat passenger performs an operation related to the passenger seat, the operation is not accepted.

That is, the display display D1 is a state in which an operating device is assigned to each seat.

Hereinafter, in the display D2, the operation buttons for seat control or window control are shared between the driver's seat and the passenger seat. In this case, if the front passenger operates the window opening and closing button, the window on the passenger side is controlled to open and close, and if the driver's seat occupant operates the window opening and closing button, the window on the driver's side is controlled. Open and close control.

In addition, in the state where the monitor display D2 is displayed, when the passenger seat operator operates the seat control button, the seat adjustment control of the passenger seat is performed, but when the driver seat operator operates the seat control button, it is desirable not to accept The operation. This is because if the seat is adjusted during driving, a problem in safe driving may occur. That is, here, the adjustment of the seat is regarded as an operation subject to travel restriction for the driver's seat occupant.

Then, the display display D1 and the display display D2 can be mutually switched according to the amount of information to be displayed on the display or its priority order.

In this way, by using the operator's designation to control the action of the vehicle-mounted device, it is possible to prevent occupants other than the driver from participating in the driving operation, prevent centralized management of vehicle body equipment from setting authority, and misuse in individual control, and realize the control by individual control. The miniaturization of the input device brought about by the sharing of the operating device.

However, when the physical operation mechanism 110 receives an operation, the operation state is reflected on the state of the physical operation mechanism 110 . For example, the lever that operates the blinker has a different position in the on state and in the off state.

If such an operating device is controlled by an operator's designation to accept an operation, the control may not be performed even though the lever is moved to the open position by the operation, and the state of the operating device may not match the operating state.

From this point, the physical operation mechanism 110 that is controlled by an operator designation is suitable for a mechanism such as a snap switch that returns to a predetermined position after an operation is received regardless of the operating state. Also, when using a mechanism in which there is a possibility that the operating state and the operating state may not match, it is desirable to notify when there is a difference.
