At the same time, the switching of the control state is output from the voice device 14 as voice guidance.

Here, in step A17, when a predetermined time elapses while waiting for an input signal from the composite input unit 11, the control unit 12 stops the operation of the display device 13 and turns off the screen display.
In step A15, when the switching operation button 11b or 11c of the composite input unit 11 is operated within a predetermined time, the control unit 12 invalidates this operation in step A18 and returns to step A15 again.

  Thus, according to the embodiment of the present invention, since the driver only operates for switching the control state of the electrical components 21 to 26, the operability is improved. improves. Further, the switch operation screens I3 related to the respective electrical components 21 to 26 are displayed one by one on the display screen 13a of the display device 13 one by one by the operation of the switching operation button 11b or 11c, so that the visibility is improved and the operation is improved. A person can easily and quickly grasp the types, functional descriptions, and control states of the electrical components 21 to 26.

Next, referring to FIG. 7, an interruption operation by starting the operation of each electrical component 21 to 24 will be described in the case of the clearance sonar device 22.
In FIG. 7, when the clearance sonar device 22 detects an obstacle in step B2 from the display state of the normal screen I2 shown in step B1, the clearance sonar device 22 outputs detection operation state information S4 to the control unit 12. To do. Thereby, based on this information S4, the control unit 12 outputs the information SI3 of the switch operation screen I3 related to the clearance sonar device 22 to the display device 13, and the clearance sonar is displayed on the display screen 13a of the display device 13 in step B3. A switch operation screen I3 related to the device 22 is displayed (see FIG. 5B).

  In step B4, the switch operation screen I3 is displayed and the input from the composite input unit 11 is awaited. When a predetermined time (for example, 5 seconds) elapses while waiting for the input, the control unit 12 returns to the normal state again. The information SI2 on the screen I2 is output to the display device 13, and the process returns to step B1 to display the normal screen I2 on the display device 13 again.

  On the other hand, when the determination operation button 11a of the composite input unit 11 is operated within a predetermined time in step B4, the determination input signal S1 is output from the composite input unit 11 to the control unit 12. In response to this, the control unit 12 outputs a control signal S3 to the clearance sonar device 22 in step B5, switches the control state to turn off, and sets the information SI3 on the switch operation screen I3 related to the clearance sonar device 22. Among them, the information regarding the control state is changed and output to the display device 13. Thereby, the switch operation screen I3 regarding the clearance sonar device 22 whose control state has been changed is displayed on the display screen 13a of the display device 13. At the same time, the switching of the control state is output from the voice device 14 as voice guidance.

When a predetermined time elapses while waiting for an input signal from the composite input unit 11 in step B5, the control unit 12 outputs the information SI2 of the normal screen I2 to the display device 13 again, and returns to step B1 to display the display device. 13 again displays the normal screen I2.
Such an interruption operation is performed in the same manner when the tire pressure sensor device 21 detects a decrease in tire air pressure, or when the parking assist device 23 starts to operate, and the control state can be switched. In this case, the switch operation screen I3 related to the electrical components 21, 22, and 23 is automatically displayed on the display screen 13a of the display device 13 with the start of the operation. There is no need to call I3 by operating the composite input unit 11, and the operability is improved.

  In the above-described embodiment, the tire pressure sensor device 21, the clearance sonar device 22, the parking assist device 23, the intrusion sensor 24, and the AFS device 25 are illustrated as the electrical components whose control state should be switched. The tire pressure sensor device 21, the clearance sonar device 22, and the parking assist device 23 are exemplified as the electrical components. However, the electrical components whose control state should be switched are not limited to these, and other electrical components such as smart switches, for example. Obviously, the control state 26 can also be switched.

Moreover, the switching order of each electrical component by the switching operation button 11b or 11c of the composite input unit 11 is not limited to that illustrated in the embodiment, and may be arranged in any order. Note that the switching order of each electrical component is preferably determined in consideration of the importance of each electrical component, the switching frequency of the control state, and the like. For example, the following priority order may be set as the order in which the display screen of the desired device is automatically switched (interrupt operation) from the normal meter display.
First priority: Automatically switch to the tire pressure initialization switch display screen when the tire pressure decreases.
Second priority: When the clearance sonar device detects an obstacle, it switches to the clearance sonar device display screen.
Third priority: When the gear is in reverse (R), the display screen related to the parking assist device 23 is switched.
The interrupt operation based on the above first to third priorities is prioritized over the screen switching operation by the composite input unit 11, but is operated by the composite input unit 11 after manual switching (manual operation). May be configured to give priority to manual operation.
Furthermore, in the above-described embodiment, the case has been described in which the switching operation button 11c returns to the previous electrical component in the reverse direction with respect to the switching order of each electrical component. It is also possible to switch to the next electrical component in the forward direction with respect to the switching sequence of each electrical component by the above operation.
