Hereinafter, embodiments of the in-vehicle device control system 100, the in-vehicle device control device 1, and the vehicle control device 2 according to the present invention will be described in detail with reference to the drawings.

The in-vehicle device control system 100 according to the present embodiment includes, as shown in FIG. 1, an in-vehicle device control device 1 installed in a house H1, and a vehicle control device 2 mounted in an electric vehicle EV1.

The electric vehicle EV1 is equipped with on-vehicle devices 3 (for example, an air conditioner 3A, an air purifier 3B, an ion generator 3C, and the like) for adjusting the in-vehicle environment. These in-vehicle devices 3 are supplied with power from the main battery 4 and operate when the electric vehicle EV1 is traveling.

The positive electrode and the negative electrode of main battery 4 are electrically connected to feed path Lp1 of charging cable 7 via charging inlet 5 and charging connector 6 of electric vehicle EV1. Further, the positive electrode of the main battery 4 is electrically connected to one of the switching contacts 220 of the switching unit 22 described later.

The charging cable 7 includes a communication path Ls1 in addition to the feed path Lp1. A charging connector 6 is provided at the tip of the charging cable 7. The charging connector 6 is electrically connected to the charging inlet 5 of the electric vehicle EV1 so as to be insertable and removable. The feed line Lp1 is electrically connected to the power conversion device 8 installed in the house H1.

The power conversion device 8 converts AC power supplied from a commercial power system 9 (that is, an external power supply) into DC power, and supplies the converted DC power to the electric vehicle EV1 through the power feeding path Lp1. However, when the solar power generation system is installed in the house H1, the power conversion device 8 is configured to convert AC power or DC power output from the power conditioner of the solar power generation system into desired DC power. It does not matter. Although illustration is omitted, a distribution board for houses is installed in the house H1, and AC power supplied from the electric power system 9 is transmitted to the power converter 8 through the distribution board for houses. Supplied.

When the resident returning home by the electric vehicle EV1 electrically connects the charging connector 6 to the charging inlet 5, the communication path of the charging cable 7 from the charging control device (not shown) mounted on the electric vehicle EV1 is A command to start charging is transmitted via the interface. The communication channel of the charging cable 7 is a communication channel other than the communication channel Ls1. Then, the power conversion device 8 that has received this command supplies DC power (charging current) to the electric vehicle EV1 through the power feeding path Lp1. In the electric vehicle EV1, the main battery 4 is charged with DC power supplied via the power feeding path Lp1 of the charging cable 7. Then, when the main battery 4 is fully charged, the charge control device transmits a command instructing charge termination to the power conversion device 8 through the communication path. The power conversion device 8 stops the operation of power conversion when it receives a command instructing charge termination.

The in-vehicle device control device 1 includes a control unit 10, an input reception unit 11, a transmission unit 12, and the like. The input receiving unit 11 includes input devices such as a push button switch and a touch panel, and receives various operation inputs by operating the input device. Then, the input reception unit 11 outputs a signal corresponding to the received operation input to the control unit 10.

The control unit 10 has a microcontroller as a main component, and realizes various functions by executing software (programs) stored in a memory with the microcontroller. For example, when the control unit 10 receives a signal corresponding to the operation input output from the input reception unit 11, the control unit 10 generates a control command corresponding to the received operation input. For example, when the input reception unit 11 receives an operation input for starting the operation of the air conditioner 3A of the electric vehicle EV1, the control unit 10 generates a control command instructing the operation start of the air conditioner 3A. The transmission unit 12 modulates a transmission frame including the control command generated by the control unit 10, and transmits the modulated signal (transmission signal) to the vehicle control device 2 via the communication path Ls1.

Here, in the in-vehicle device control device 1, components such as the control unit 10, the input receiving unit 11, and the transmission unit 12 are accommodated in a box-shaped housing 13 and installed on a wall of a living room or the like. However, the in-vehicle device control device 1 may be configured integrally with the master unit of the intercom system.

The vehicle control device 2 includes a device control unit 20, a receiving unit 21, a switching unit 22, relays 23 to 25, and the like. The receiving unit 21 receives the transmission signal transmitted from the transmitting unit 12 of the in-vehicle device control device 1 via the communication path Ls1. Furthermore, the receiving unit 21 demodulates the transmission frame from the received transmission signal, and outputs the control command extracted from the transmission frame to the device control unit 20.

The switching unit 22 includes two switching contacts 220 and 221 and one common contact 222, and is configured of a relay configured to switch and connect the common contact 222 to either one of the switching contacts 220 and 221 alternatively. Become. Further, in the switching unit 22, one switching contact 220 is electrically connected to the positive electrode of the main battery 4, and the other switching contact 221 is electrically connected to the feeding path Lp 1 of the charging inlet 5. Furthermore, the common contact 222 of the switching unit 22 is electrically connected to one end of the three relays 23, 24, 25. That is, switching unit 22 selects one of the first path for supplying power to in-vehicle device 3 from main battery 4 of electric vehicle EV1 and the second path for supplying power to in-vehicle device 3 from electric power system 9 through charging inlet 5. Configured to switch However, the positive electrode of the main battery 4 and the charge inlet 5 are bypassed by another path in which the rectifying element (diode D1) is inserted. Therefore, the main battery 4 can be charged with DC power supplied via the charge inlet 5 regardless of the state of the switching unit 22.

One end of the relay 23 opposite to the common contact 222 is electrically connected to the air conditioner 3A. Further, one end of the relay 24 opposite to the common contact 222 is electrically connected to the air cleaner 3B. Further, one end of the relay 25 opposite to the common contact 222 is electrically connected to the ion generator 3C. That is, each on-vehicle device 3 (air conditioner 3A, air purifier 3B, ion generator 3C) is supplied with power when the relays 23, 24 and 25 are on and operates, and the relays 23, 24 and 25 are off If it does, it will stop because it is not powered.

Next, referring to the sequence chart of FIG. 2, the resident of the house H1 who wants to go out operates the air conditioner 3A in advance to keep the temperature inside the vehicle EV1 at the time of departure at a comfortable temperature. While explaining.

First, upon receiving an operation input for operating the air conditioner 3A (step S1), the input reception unit 11 outputs a signal corresponding to the received operation input to the control unit 10. When the control unit 10 receives the signal, the control unit 10 generates a control command for starting the operation of the air conditioner 3A (step S2), and outputs the generated control command to the transmission unit 12. The transmission unit 12 transmits the transmission signal obtained by modulating the transmission frame including the control command to the vehicle control device 2 via the communication path Ls1 (step S3).

The receiving unit 21 of the vehicle control device 2 receives the transmission signal transmitted through the communication path Ls1 (step S4), and demodulates the transmission frame from the transmission signal and outputs the acquired control command to the device control unit 20. . The device control unit 20 starts processing for operating the air conditioner 3A according to the control command received from the receiving unit 21.

In addition, the device control unit 20 performs switching control of the switching unit 22 (step S5). The switching unit 22 switches and controls the common contact 222 from the switching contact 220 on the main battery 4 side to the switching contact 221 on the charge inlet 5 side under switching control of the device control unit 20 (step S6). That is, when the receiving unit 21 receives the control command, the device control unit 20 controls the switching unit 22 to switch to the second path. As a result, the main battery 4 is separated electrically (in direct current) from the in-vehicle device 3.

Subsequently, the device control unit 20 turns on the relay 23 (step S7). The relay 23 is turned on by the device control unit 20 and turned on (step S8). When the relay 23 is turned on, the air conditioner 3A starts operating. At this time, the switching unit 22 electrically connects the air conditioner 3A to the power feeding path Lp1 via the charging inlet 5. Therefore, the air conditioner 3A operates not with the main battery 4 but with DC power supplied from the power conversion device 8. However, when the main battery 4 is fully charged, the device control unit 20 performs switching control of the switching unit 22 to switch connection to the charge inlet 5 side, and then supply power to the power conversion device 8 for the charge control device. Tell them to start.

Here, the control unit 10 of the in-vehicle device control device 1 counts the elapsed time since the control command of the operation start is generated and output to the transmission unit 12. Then, when the elapsed time reaches a predetermined time, the control unit 10 generates a control command for stopping the operation of the air conditioner 3A (step S9), and outputs the generated control command to the transmission unit 12. The transmission unit 12 transmits the transmission signal obtained by modulating the transmission frame including the control command to the vehicle control device 2 via the communication path Ls1 (step S10).

The receiving unit 21 of the vehicle control device 2 receives the transmission signal transmitted through the communication path Ls1 (step S11), and demodulates the transmission frame from the transmission signal and outputs the acquired control command to the device control unit 20. . The device control unit 20 starts processing for stopping the air conditioner 3A in response to the control command received from the receiving unit 21.

The device control unit 20 turns off the relay 23 (step S12). The relay 23 is turned off by the device control unit 20 and turned off (step S13). When the relay 23 is turned off, the air conditioner 3A stops operating.

Subsequently, the device control unit 20 performs switching control of the switching unit 22 (step S14). The switching unit 22 switches and controls the common contact 222 from the switching contact 221 on the charge inlet 5 side to the switching contact 220 on the main battery 4 side under switching control by the device control unit 20 (step S15).

However, when the connection of the charge inlet 5 and the charge connector 6 is released before the elapsed time reaches the predetermined time, the device control unit 20 turns off the relay 23 to stop the air conditioner 3A. Furthermore, after turning off the relay 23, the device control unit 20 controls the switching unit 22 to switch and connect the common contact 222 from the switching contact 221 on the charge inlet 5 side to the switching contact 220 on the main battery 4 side. If the device control unit 20 has a configuration for monitoring the line voltage of the communication path Ls1, for example, the connection of the charge inlet 5 and the charge connector 6 is released based on the line voltage. Can be judged.

As described above, the in-vehicle device control system 100 of the present embodiment is electrically connected to the vehicle control device 2 through the communication path Ls1 and the vehicle control device 2 mounted on the electric vehicle EV1 to control the operation of the in-vehicle device 3 And an in-vehicle device control device 1. The in-vehicle device control device 1 includes an input receiving unit 11 that receives an operation input, and a control unit 10 that generates a control command for controlling the operation of the in-vehicle device 3 based on the operation input received by the input receiving unit 11. . In addition, the in-vehicle device control device 1 further includes a transmission unit 12 that transmits (transmits) a control command to the vehicle control device 2 via the communication path Ls1. The vehicle control device 2 includes a receiving unit 21 that receives a control command, and a device control unit 20 that operates the in-vehicle device 3 according to the control command. The device control unit 20 supplies the power supplied via the charging inlet 5 of the electric vehicle EV1 to the on-vehicle device 3 to operate.

In particular, in the present embodiment, the vehicle control device 2 supplies power from the power system 9 to the in-vehicle device 3 through the charging inlet 5 and the first path for supplying power to the in-vehicle device 3 from the main battery 4 of the electric vehicle EV1. The switching unit 22 selectively switches between the two paths. Then, when the receiving unit 21 receives the control command, the device control unit 20 controls the switching unit 22 to switch to the second path.

Further, the in-vehicle device control device 1 of the present embodiment generates a control command for controlling the operation of the in-vehicle device 3 based on the operation input received by the input reception unit 11 that receives an operation input and the operation reception received by the input reception unit 11. And a control unit 10.

Therefore, in the in-vehicle device control system 100, the in-vehicle device control device 1, and the vehicle control device 2 of the present embodiment, the in-vehicle device 3 is operated by the power supplied from the house H1 (power system 9) via the charging inlet 5. The discharge of the main battery 4 is not necessary for the operation of the in-vehicle device 3. Therefore, the present embodiment suppresses the shortening of the cruising distance of the electric vehicle EV1 due to the decrease in the charge level of the main battery 4 as compared with the case where the vehicle battery 3 is operated by constantly supplying power from the main battery 4. The in-vehicle environment can be maintained in a comfortable state.

Further, in the present embodiment, the vehicle control device 2 is electrically connected to the plurality of in-vehicle devices 3 via the relays 23 to 25 respectively. Then, the device control unit 20 individually controls on / off of the plurality of relays 23 to 25 in accordance with the control command. In this configuration, the plurality of on-vehicle devices 3 (here, the air conditioner 3A, the air cleaner 3B, and the ion generator 3C) can be operated individually.

Further, in the present embodiment, the control unit 10 of the in-vehicle device control device 1 generates a control command for stopping the operation of the in-vehicle device 3 when a predetermined time has elapsed since the in-vehicle device 3 started operation. It is preferable to make the transmitting unit 12 transmit. For example, if the resident of the house H1 forgets that the in-vehicle device 3 is operated, if the in-vehicle device 3 continues to operate for a long time, wasteful power consumption will increase. On the other hand, in this configuration, when the operation time reaches a predetermined time, the control command for stopping the operation of the in-vehicle device 3 is given from the in-vehicle device control device 1 to stop the in-vehicle device 3. It can be suppressed. Since the processing from step S3 to step S8 in FIG. 2 is completed in about one second, the elapsed time since the control unit 10 generates the control command of operation start and outputs it to the transmission unit 12 is There is no problem even if it is regarded as the operation time of the device 3.

Alternatively, in the present embodiment, when the device control unit 20 operates the in-vehicle device 3 according to the control command and power feeding via the charging inlet 5 continues even if a predetermined time has elapsed, the in-vehicle device 3 You may stop the operation of. Thus, even if the device control unit 20 of the vehicle control device 2 stops the on-vehicle device 3 after a predetermined time has elapsed instead of the control unit 10 of the in-vehicle device control device 1, it is possible to suppress an increase in wasteful power consumption. it can.

The vehicle control device 2 in the present embodiment separates the main battery 4 from the in-vehicle device 3 while power is supplied to the in-vehicle device 3. In this way, the load on the main battery 4 is reduced as compared to the case where the discharge from the main battery 4 to the in-vehicle device 3 and the charging of the main battery 4 are performed in parallel, and the short life of the main battery 4 is achieved. Can be suppressed.

Furthermore, the vehicle control device 2 in the present embodiment is configured to be able to perform power feeding (charging) to the main battery 4 in parallel with power feeding to the in-vehicle device 3. Therefore, while the main battery 4 is charging, the in-vehicle apparatus 3 can be operated to maintain the in-vehicle environment in a comfortable state.

In the present embodiment, a feed path Lp1 for supplying power for charging from the power conversion device 8 to the main battery 4 and a feed path for supplying operation power from the power conversion device 8 to the in-vehicle device 3 It is shared with Lp1. However, it is not necessary to share these two types of feed paths, and a feed path for supplying operation power from the power conversion device 8 to the on-vehicle device 3 may be a dedicated feed path independent of the charging feed path. It does not matter.

Further, in the present embodiment, the communication path Ls1 connecting the transmission unit 12 of the in-vehicle device control apparatus 1 and the reception unit 21 of the vehicle control apparatus 2 is a dedicated communication path. However, it is not necessary to use a dedicated communication path. For example, the charge control device of the electric vehicle EV1 may share a communication path for communicating with the power conversion device 8. Alternatively, the communication path Ls1 may be an antenna, and the transmitter 12 and the receiver 21 may perform radio communication using radio waves as a communication medium.
