The operation of the first embodiment will be described below with reference to the flowchart of FIG.

In the first embodiment, the position of the alarm display is changed according to the line of sight of the driver. That is, the position of the master warning display is changed depending on where the driver is looking while driving.

First, in step S1, the vehicle state is read. The reading of the vehicle state is to read a signal from the vehicle state detecting section 2, that is, a signal of a hydraulic pressure warning sensor, a charging warning sensor, or the like.

Next, in step S2, it is determined whether or not a vehicle warning is required. This judgment is made based on whether the read signal exceeds the set value as described above. If it is determined that the warning is not required, the reading of the vehicle state in step S1 is continued.

If it is determined that an alarm is required, the vehicle status is displayed in step S3. This vehicle state display is performed by a signal output to the individual display unit 3, and for example, a hydraulic pressure warning light, a charging warning light, etc. are turned on. It should be noted that this vehicle state display is not limited to lighting of a hydraulic pressure warning or the like, but may be a state in which a hydraulic pressure state or a charging state is displayed by a meter or the like.

Next, in step S4, the line of sight of the driver is read, and in step S5, the gazing point of the driver is calculated. The processing of these steps S4 and S5 is performed by the visual line analysis device 31.

Next, in step S6, the driver's gaze area is determined. This judgment is made by the master warning optimum display position judgment circuit 65.
The master warning optimum display position determination circuit 65 determines an appropriate display position of the master warning display based on a signal from the line-of-sight analysis device 31 based on a preset database. As a result, the areas A to L are determined as shown in FIG. 6, and the optimum position is determined. If it is determined to be the region L (step S7), HU is determined in step S8.
A master warning is displayed on D. This master warning display is based on the master warning display section 5
5 is performed. Further, if it is determined to be the region H (step S9), the master warning is displayed in the meter in step S10. The same determination is made in the other areas as well, and the master warning is displayed in step S12. In this case, in order to simplify the illustration, the regions L and H are collectively grouped, and the others (step S11) and other displays (step S1) are displayed.
Although it is described as 2), in such other areas as well, like the areas L and H, individual judgments are made and individual master warning displays are performed.

Therefore, depending on which of the areas A to L is being watched by the occupant during driving, the master warning can be displayed in that area correspondingly. Therefore, the master warning display can be promptly and properly recognized when an alarm condition of the vehicle becomes necessary due to a decrease in the oil pressure of the engine lubricating oil.

Further, by recognizing such a master warning display, it is possible to prompt confirmation of each warning lamp of the individual display section 3, and it is possible to quickly and properly recognize the place where the vehicle needs an alarm. , I can take prompt action.

FIG. 9 shows a control flowchart of the second embodiment.

Also in this flowchart, the basic steps are the same as those in the flowchart of the first embodiment of FIG. 8, and the same reference numerals are given and the duplicated description will be omitted. On the other hand, in this embodiment, when gazing at a specific position during driving,
The master warning is displayed in the discrimination field of view. Therefore, after calculating the driver's gazing point in step S5,
In step S21, it is determined whether or not the user is gazing at a specific position, such as the front side or the meter. In this determination, when the human line of sight is stopped at a specific position for 100 ms or more, it is determined that the region is gazing. If it is determined that the specific position is the front gaze of the front front (step S22), the HUD is determined in step S23.
A master warning is displayed in the upper field of discrimination.
If the specific position is the meter and it is determined that the meter is gazing, the master warning is displayed in the discrimination visual field of the meter in steps S24 and S25.

The display in the discrimination visual field is performed by finding the closest one within a radius of 5 degrees from the gazing point among a plurality of master warning displays preset in a specific position, It is displayed in the vicinity of 5 degrees. The reason for displaying in the vicinity of the radius of 5 degrees is to eliminate the unpleasant sensation. Further, the reason for displaying in the discrimination field of view is to enable the master warning display to be recognized quickly without difficulty.

Further, the information displayed in the discrimination visual field is only at the time of gazing at the meter and the gazing at the front, but this is a gazing state which is extremely important for driving the vehicle, and these gazing are made by the master warning display. This is to prevent the state from being interrupted as much as possible. However, it is possible to display in the discrimination visual field only when either the meter gazing or the front gazing, and further it is possible to display in the discrimination visual field when gazing at another specific position.

If it is determined in step S21 that the specific position is not being watched, another master warning display corresponding to the line-of-sight position is displayed in step S26. Therefore, in this embodiment, the master warning display can be performed according to the driver's line-of-sight position, and further, the master warning display can be performed within the discrimination visual field in the state of the front gaze or the meter gaze, and the master warning display can be performed more quickly and reliably. Can be recognized. Further, by displaying the master warning display in the discrimination visual field in the front gaze or the meter gaze, the front gaze and the meter gaze can be promoted as much as possible.

FIG. 10 shows a flowchart according to the third embodiment.

Also in this embodiment, the same steps as those in the flow chart of the first embodiment of FIG. 8 are designated by the same reference numerals and the duplicated description will be omitted. On the other hand, in this embodiment, when the driver is gazing at the pointer, the master warning is displayed on the pointer. In many cases, when a driver looks at a pointer, he or she looks at the pointer to display a master warning in the discrimination visual field. That is, in step S31, it is determined whether or not the driver is gazing at the pointer, and if the driver is gazing at the pointer, a master warning display is displayed on the pointer in step S32. Thereby, the master warning display can be performed within the discrimination visual field. In this case, the function of the master warning display is substituted by changing the color of the pointer from the white pointer to the red pointer or by blinking the light of the pointer. If it is determined in step S31 that the indicator is not being watched, the master warning display is performed in step S33 according to the position of the line of sight of the occupant.

FIG. 11 shows the pointer B on which the master warning is displayed as described above. That is, the color of the tip b of the pointer b has changed. As a result, when the driver is gazing at the pointer, it is possible to easily perform the master warning display in the discrimination visual field.

FIG. 12 shows a flowchart according to the fourth embodiment.

Also in this flowchart, the same reference numerals as those in the flowchart according to the first embodiment of FIG. On the other hand, in this embodiment, when the master warning display portion is not in the driver's discrimination visual field, the master warning display brightness is increased to make it easier to notice. That is, in step S41, it is determined whether or not the master warning display portion is within the driver's discrimination visual field. If it is determined that the master warning display unit is not present in the discrimination visual field, the master warning warning display is changed in step S42. Next, in step S43, the master warning display is performed to increase the display brightness or blink the display, and further change the display state or change the color. On the contrary, if it is determined in step S41 that the master warning display unit is within the driver's discrimination visual field, the master warning display without changing the display is performed in step S44. Therefore, according to this embodiment, the master warning display can be easily noticed even when the driver does not have the display unit in the discrimination visual field and the master warning display must be confirmed in the peripheral visual field. Therefore, it is possible to reduce the number of master warning display portions, and the cost can be reduced.

FIG. 13 shows a flowchart according to the fifth embodiment.

Also in this embodiment, the same steps as those in the first embodiment shown in FIG. 8 are designated by the same reference numerals, and the duplicated description will be omitted. On the other hand, this embodiment is an example when the master warning display portion is not in the driver's discrimination visual field as in the fourth embodiment. That is, if it is determined in step S51 that the master warning display unit is not in the driver's discrimination field of view, the master warning warning display is changed in step S52, and the background color of the entire meter display unit is changed or blinking in step S53. For example, the display of the master warning display is changed. Step S54 is a normal master warning display. Therefore, also in this embodiment, the master warning display can be easily noticed by the driver's peripheral vision.

FIG. 14 shows an example of the master warning display in step S53. (A) shows before the master warning is displayed, and (b) shows after the master warning is displayed. In the master warning display of (b), the distribution color of the entire meter display unit is changed.

FIG. 15 shows a flowchart according to the sixth embodiment.

In this embodiment, a driving state detecting means for detecting the driving state of the driver is provided, and the stimulus level of the master warning display is controlled according to the driver's concentration of driving operation. The internal circuit of FIG. 2) functions as an operating state detecting means. That is, in step S61, it is determined whether or not the master warning display portion is in the driver's discrimination visual field, and if the master warning display portion is not in the discrimination visual field, the driving situation is read in step S62. This driving status is read in, for example, accelerator opening, vehicle speed, shift operation,
It is based on detection signals such as brake operation and steering angle, which are read as predetermined values. After the driving status is read, step S63
At, the degree of concentration of driving operation is determined. It is assumed that this determination concentrates on the driving operation when the read predetermined value exceeds the reference value stored in the controller in advance. The relationship between these reference values and predetermined values is as follows.

Time derivative Σ (da / dt)> θ1 (S1 is a reference value) of accelerator opening a within a fixed time. Time derivative Σ (dv / dt)> θ2 (S2 is a reference value) of speed v. Time derivative Σ (d of steering angle θ in a fixed time
θ / dt)> θ3 (S3 is a reference value) ・ The number of shift operations within a certain period is a certain number or more ・ The number of brake operations (or pedaling force) is a certain number (a certain value) or more If it is determined that the stimulus is present, the stimulus level in the peripheral visual field of the master warning display is controlled in step S64.

Next, in step S65, the master warning display is performed with the stimulation level adjusted. That is, it is not a color that changes the color that changes or changes the brightness of the master warning display slightly,
When the color is changed to be a little changed, or when the color is gradually changed and further blinked, the display is adjusted such that the blinking cycle is gentle. The master warning display may not be performed in step S65. Then, step S6
If it is determined in 3 that the driver is not concentrated on the driving operation, the normal master warning display is performed in step S66. Therefore, in this embodiment, the stimulus level of the master warning display can be adjusted according to the concentration of the driving operation, and the concentration of the driving operation can be maintained regardless of the master warning display.

FIG. 16 shows a flowchart according to the seventh embodiment.

The seventh embodiment has substantially the same structure as the sixth embodiment, but is different in that a physiological condition detecting means is provided instead of the operating condition detecting means provided in the sixth embodiment.
The internal circuit of the microcomputer 67 (FIG. 2) functions as an operating state detecting means. That is, in step S62 of the sixth embodiment, the driving situation is read according to the accelerator opening degree, whereas in the seventh embodiment, in step S62, heart rate, electroencephalogram, electrocardiogram, driving time, line-of-sight analysis device, etc. The operation status is read based on the detection signal of. Then, in step S63,
The determination of the degree of concentration of driving operation is made based on whether or not a predetermined detection value exceeds a certain value stored in the controller. Specifically, ・ The number of blinks within a certain period of time and the eye closing time are above a certain value ・ The amplitude value of the α-wave component of the electroencephalogram is above a certain value ・ Concentrate on driving operation when the RRV value of heartbeat is above a certain value・ If the number of blinks within a certain period of time and the closing time of the eye are a certain value or more ・ The amplitude value of the α-wave component of the electroencephalogram is a certain value or more ・ Driving operation when the RRV value of the heartbeat is a certain value or more It is determined that they are concentrated on. This detects the driver's physiological state such as drowsiness and fatigue,
Judging the degree of concentration on the driver according to the physiological condition of the driver, when the driver is concentrating on the driver, the master warning display is not performed as in the sixth embodiment or the stimulation level is reduced so that the driving operation is less burdened. To do. Further, when the user is not concentrated on the driving operation, it is possible to urge the driver to increase the degree of concentration with a stronger stimulation level.

FIG. 17 shows a flowchart according to the eighth embodiment.

Also in this embodiment, the same steps as those in the first embodiment of FIG. 8 are designated by the same reference numerals, and the duplicated description will be omitted. On the other hand, in this embodiment, the master warning peripheral visual field display level is controlled according to the urgency of the warning display, and the warning of the vehicle detected by the driving state detection unit 2 (FIG. 2) is required. Urgency determining means for determining the urgency is provided, and the internal circuit of the microcomputer 67 (FIG. 2) constitutes the urgency determining means. That is, in step S71, it is determined whether or not there is a master warning display unit in the driver's visual field for discrimination, and if it is determined that the master warning display portion is not present, the process proceeds to step S72. In step S72, the urgency of the alarm is determined. For example, if the user forgets to release the side brake, it must be dealt with immediately when the master warning is displayed, and the alarm device has a high degree of urgency. In addition, it is judged that the lack of washer fluid is not so urgent. If it is determined that the urgency is high, step S7
3, the master warning peripheral visual field display level is controlled. This control raises the stimulus level by slightly raising the brightness of the master warning display. Next, in step S74, the master warning is displayed in the state where the stimulation level is high. If it is determined in step S72 that the urgency is not high, the normal master warning display is performed in step S75. Note that step S
At 75, it is also possible to reduce the stimulus level by lowering the brightness of the master warning display.

Therefore, in this embodiment, the master warning display can be changed according to the difference in the urgency of the alarm display, and particularly when the urgency is high, the strong stimulus emphasizes the high urgency. be able to.

That is, the right and left vertical angles from the driver's gazing point to all master warning display positions are calculated, and the discrimination visual field (upper and lower left and right within 5 degrees) and effective visual field (15 degrees up and down 12 degrees up and down)
Degree), stable field of view (left and right angles 30 to 45 degrees, up 20 to 3
The proper display position is determined by determining 0 degree, 20 to 40 degrees downward, and a guided visual field (left and right angles of 50 degrees, 40 degrees above, 45 degrees below). Then, the master warning display is preferentially performed in the order of the discrimination visual field, the effective visual field ... In this case, when a plurality of master warning display units are in the same field of view, the display position with a smaller angle is extracted as the proper display position. Thereby, the master warning display can be more accurately performed according to the line of sight of the occupant.

Further, there are the following methods for calculating the driver's gazing point. That is, the hip point is estimated from the seat slide and seat lifter positions, and the eye point coordinates are calculated from the hip point, the driver's physique (height, sitting height, etc.), the seat back angle, and the seat slide and seat lifter positions.

[0098] With further described, seat slide (or sheet lifter) hip point coordinate values of the reference position of the hip point coordinates with the current seat slide position from (X0, Y0, Z0) ( X n, Y n, Z n) of Coordinate conversion is performed according to the number n of changed notches.

The exchange type is X _n = X0, Y _n = Y0 + n × A
_y , Z _n = Z0 + n × A _z (A _y and A _z are correction coefficients) Next, considering the hip point coordinates and the seat back angle (θ) thus obtained, the eye point coordinates (X _e ,
Y _e , Z _e ) is calculated as follows.

X _e = X _n , Y _e = Y _n + L × sin θ, Z
_e = Z _n + L × cos θ (L: seat height correction value) The state pattern of the black eye position that specifies which area the driver's line of sight is looking at according to the coordinate value of the eye point thus obtained is changed. or eye point coordinate values _{(X e, Y e, Z} e) using the representative coordinate position of each display position angle from to a plurality of master warning display unit L _a ~M _z, calculated in the horizontal direction and the vertical direction To do. As a result, the master warning display can be performed at a more accurate position.
