The display panel 17 is provided with a speedometer display section 19 and a multi-display section 21. The speedometer display unit 19 constantly displays the speed of the vehicle. On the other hand, the multi-display unit 21 constitutes a display means and normally displays the engine speed in the area 21a preferentially. However, when necessary, the speed display is erased and the state of other vehicles is displayed. Is displayed in the area 21b for a predetermined time. Switching between the tachometer display of the multi-display unit 21 and another state display of the vehicle is performed via a control circuit 23 and a drive circuit 25 which are configured by a microcomputer as a control means.

FIG. 3 shows a state in which a tachometer is displayed in the area 21 a of the multi-display unit 21. In the area 21b of the multi-display unit 21, for example, when the shift lever 29 of the transmission is operated, the shift position is displayed by the pressure sensor (switch) provided on the knob of the shift lever 29 as shown in FIG. 4 (a). However, when the operation lever of the winker 31 is operated, the direction switch blinks as shown in FIG. 4 (b) when the operation lever of the winker 31 is operated (hatching). Section shows blinking state). When displaying the shift position, an image by the rear monitoring device may be displayed at the reverse position. Similarly, the light switch 33 and the wiper switch 35 are similarly switched and displayed by the pressure sensor provided respectively for the lighting state of the light and the operating state of the wiper. Although not shown in Fig. 1, if each switch for confirming the remaining fuel amount and the cooling water temperature is provided, the remaining fuel amount and the cooling water temperature can be displayed by operating these switches. become.

When the radio 37 is operated, the radio station and the broadcast contents are displayed, and when the air conditioner 39 is operated, the set temperature, the wind direction, the air volume, etc. are displayed in the area 21b by the pressure sensors provided in the respective switches. Further, even when a trouble such as a vehicle failure occurs, for example, when the fuel becomes 1/4 or the cooling water temperature rises above a predetermined value, various warning sensors 41 display a warning in the area 21b. To do. When displaying the warning, it is recommended to display not only the content but also the method of handling the failure. In addition, the traffic information operation switch 43, the 4WS and the traction control system (not shown) are similarly displayed in the area 21b. In addition, a multi-display switch 45 may be provided so that two or more states, for example, two states of a fuel gauge and a temperature gauge, and three states of a fuel gauge, a temperature gauge, and a shift position can be simultaneously displayed in the area 21b. .

The various states of the vehicle displayed in the area 21b of the multi-display unit 21 are preset with an urgency for notifying the user, that is, a priority order for displaying. For example, if A, B, C are ranked in descending order of urgency, A: warning, fuel gauge, cooling water temperature gauge, B: blinker, C: shift position, light, wiper, radio, air conditioner, Traffic information, telephone (list of numbers), multi-display ,.

Next, a specific configuration of the display panel 17 is shown in FIG. FIG. 5A is a cross-sectional view of the multi-display unit 21. The multi-display unit 21 is arranged such that a half mirror 45 and a transmission hologram 47 are sequentially stacked from the driver D side and are inclined. . A tachometer indicator 49 is arranged above the half mirror 45, and a status indicator 51 for indicating another status is arranged below the transmission hologram 47. FIG. 6 is an enlarged view of FIG. 5A, in which the transmission hologram 53 is sandwiched between two pieces of glass 55 and 57, and a vapor deposition surface 59 constituting the half mirror 45 is formed on the surface of the glass 55.

Here, by turning on the illumination lamp of the tachometer display 49, the driver can see the tachometer display 49 reflected by the half mirror 45. On the other hand, when the illumination lamp of the status indicator 51 is turned on, the light (image) of the status indicator 51 is refracted by the transmissive hologram 47, so that the driver can see the status indicator 51.

FIG. 5B is a cross-sectional view of the speedometer display unit 19. In the speedometer display unit 19, only the half mirror 45 is tilted and arranged. A speedometer display 61 is arranged above the half mirror 45 so that the driver D can see the speedometer display 61 reflected by the half mirror 45.

FIG. 7 shows another example of the multi-display unit 21. The multi-display unit 21 is arranged so that the half mirror 45 is tilted with respect to that of FIG. A tachometer display 49 is arranged on the same straight line as the viewpoint of the driver D with the half mirror 45 interposed therebetween, and a status display 51 is arranged below the half mirror 45. By turning on the illumination lamp of the tachometer display 49, the tachometer display 49 can be seen through the half mirror 45. On the other hand, when the illumination lamp of the status display 51 is turned on, the status display 51 can be viewed as a virtual image reflected by the half mirror 45. In this case, in the speedometer display unit 19, the speedometer display 61 is arranged behind the half mirror 45 in parallel with the tachometer display 49, and the speedometer display 61 is similar to the tachometer display 49. It can be seen through the half mirror 45.

The speedometer display 61 as described above is a CRT, a dot matrix LCD, or an analog speedometer that emits light with higher brightness than before, and the tachometer display 49 and the status display 51 are CRTs and dots. It is a matrix LCD. The reason why half mirrors and transmissive holograms are used is to reduce the burden of focusing on the eyes of the driver by displaying a virtual image in the distance.

Next, the control operation of the control circuit 23 will be described using the flowcharts of FIGS. 8, 9, 10, 12, and 13.

FIG. 8 shows the operation according to the urgency levels A, B, and C for displaying each state of the vehicle displayed in the area 21b of the multi-display unit 21 described above. That is, it is determined whether or not the various warning sensors 41 have detected an abnormality in the vehicle in the normal state in which the tachometer is displayed (step 801) (step 803), and if it is detected, a predetermined warning is displayed (step 801). Step 805). When the warning sensors 41 have not detected any abnormality in the vehicle, it is determined whether or not the fuel gauge display operation switch has been pressed (step 807). If the switch has been pressed, the remaining fuel amount is displayed. (Step 809). In the same manner, the operating states of the cooling water temperature gauge, blinkers, shift levers, ... Are judged, and when they are operated, the desired state is displayed in the area 21b.

FIG. 9 shows a display switching operation when the shift lever 29 is operated. The driver comes into contact with the shift knob (step 901), and it is determined whether the pressure sensor provided on the shift knob detects pressure (step 903). Here, when the pressure sensor detects the pressure, the display of the multi-display unit 21 is switched from the tachometer display to the shift position display (step 905), and when not detected, the tachometer display is left as it is (step 907). It should be noted that it is convenient to change the shift range if the engine speed is also displayed when the shift position is displayed.

FIG. 10 shows a display switching operation when the light switch 33 is operated. The driver touches the light switch 33 (step 1001), and it is determined whether the pressure sensor provided in the light switch 33 detects pressure (step 1003). Here, when the pressure sensor detects the pressure, the display of the multi-display unit 21 is switched from the tachometer display to the light display (step 1005), and various lighting modes are displayed (step 1007). When the lighting mode is displayed, selection of the lighting mode, that is, the position of the light switch 33 is detected (step 1009).

When the auto mode (automatic lighting switch) is selected as the lighting mode (step 1011), the current lighting state in the auto mode is displayed (step 1013), and then the display is changed to the original tachometer display. Switch (step 1015). When the light is turned on in the auto mode, a display such as "auto mode light" is output.

When the small mode in which the small light is turned on is selected (step 1017), the road surface brightness is detected by an optical sensor provided outside the vehicle body (step 1019), and as shown in the display example of FIG. In addition to the optimum mode (light here), the currently selected small mode and the position of the light switch 33 are displayed (step 1021). The position of the light switch 33 may be displayed by turning on the portion indicated as small. When the driver confirms the displayed optimum mode and touches the light switch 33 and the pressure sensor detects the pressure (step 1023), the process returns to step 1009 and the lighting mode is selected again. If the pressure sensor does not detect the pressure in step 1023, that is, if the driver does not touch the light switch 33, the small mode is kept.

Even when the light mode in which the headlights are turned on is selected (step 1025), the road surface brightness is selected (step 1027), the optimum mode display and the light mode display and the light switch are selected as in the small mode. After the position of 33 is displayed (step 1029), the presence or absence of pressure detection by the pressure sensor of the light switch 33 is determined (step 1031).

When the lighting mode is the OFF mode, that is, when the light switch 33 is OFF (step 1031), a message to that effect is displayed (step 1033), and then the display is switched to the original tachometer display ( Step 1035).

FIG. 12 shows a display switching operation when the wiper switch 35 is operated. The driver contacts the wiper switch 35 (step 1101), and it is determined whether the pressure sensor provided in the wiper switch 35 detects the pressure (step 1103). Here, when the pressure sensor detects the pressure, the display of the multi-display unit 21 is switched from the tachometer display to the wiper mode display (step 1105). Here, the position of the wiper switch 35 is selected (step 1107), and the operation display of the wiper mode corresponding to the position is displayed, that is, the operation display of the intermittent mode or the normal mode is performed (step 1109). After the operation of the wiper mode is displayed, it is judged whether or not the pressure is detected by the pressure sensor of the wiper switch 35. If there is no pressure detection, that is, if the operation mode is not changed, the wiper display is turned off and the tachometer display is displayed. Return (step 1 113).

FIG. 13 shows a display switching operation in the intermittent mode of the wiper operation mode when the intermittent time adjustment switch is operated. When the driver touches the adjustment switch (step 1201) and the pressure sensor provided in the adjustment switch detects the pressure (step 1203), the adjustment amount, that is, the intermittent time mode is displayed (step 1205). After the intermittent time mode is displayed, the position of the adjustment switch is selected (step 1207), and the adjustment amount corresponding to the position is displayed (step 1209). After that, the presence or absence of pressure detection by the pressure sensor of the adjustment switch is judged (step 1211). If there is no pressure detection, that is, if there is no change in the adjustment amount, the adjustment amount display is turned off and the tachometer display is restored ( Step 1213).

As described above, the multi-display unit 21 of the display panel 17 displays various states of the vehicle, that is, warnings for malfunctions, fuel gauges, blinkers, shift positions, radios, etc. according to the urgency and operation. Therefore, even if the number of types of vehicle status display increases, such as the addition of road information / new system information by communication system for the purpose of vehicle automatic driving assistance and road traffic management, the speedometer will be displayed. The display part including can be made large, and these can be displayed appropriately.

The multi-display unit 21 normally displays a tachometer, and when necessary, for example, when the shift lever 29 or the light switch 33 is operated, this is detected to detect the shift position and the lighting mode. Is displayed. As a result, the driver can surely judge the operation status by looking at the multi-display unit 21, and the driver is not distracted by the operation more than necessary during driving, which contributes to safe driving.

Regarding the light switch 33, if the vehicle is equipped with an automatic lighting switch and is set to the automatic lighting mode, when the vehicle passes under a viaduct such as a daytime highway or a railroad, the head switch suddenly turns off. The light may turn on. This lighting can be seen when the display brightness of the instrument changes, and I try to turn off the light, but sometimes it does not turn off and sometimes it remains as a small light. However, since the lighting mode is displayed on the multi-display unit 21 as in the above-described embodiment, such a forgetting to turn off the light is prevented. In addition, when the road is dim, it usually runs with small lights, but in places such as urban areas where road lighting is maintained, small lights may drive even when it gets very dark. Even in such a case, since the lighting mode is displayed on the multi-display unit 21, the driver can appropriately operate the light switch 33 by checking this.

Regarding the wiper, for switching between the intermittent mode and the normal mode, speed adjustment in the normal mode, or adjustment of the intermittent time in the intermittent mode, at present, the wiper speed is confirmed by actually rotating the wiper several times. However, since the various modes of the wiper are displayed on the multi-display unit 21, such a problem can be prevented.
