In FIG. 5, the operation system / display control unit 14 outputs tachometer information to the second projection display device 12 in order to perform the tachometer display shown in FIG. 3 as an initial display during normal traveling, An initial display is performed (step 101). Next, it is determined whether or not a switch touch by which the worker touches the centralized operation switch 13 is performed according to the input of the switch touch signal (step 102).

If the switch has not been touched, the process returns to step 101 to continue the initial display. When the switch is touched, the initial display is switched to the operation menu display based on the operation menu image, and is displayed on the second projection display device 12 (step 103). Further, when an operation system is selected by the joystick switch mechanism of the centralized operation switch 13, the display of the first projection display device 11 is controlled to display a picture according to the selected operation system. In the example of FIG. The control is switched to the picture display of the navigation system and the audio equipment (step 104), and the process returns to step 101.

First, it is determined whether or not the switch operation of the centralized operation switch 13 has been interrupted (step 201). Here, the interruption is determined based on whether or not the operator has touched the central operation switch 13.

If the interruption has not been made, the display of the currently displayed menu is maintained (step 202). When the interruption is performed, it is determined whether the interruption of the operation has elapsed for T1 seconds (step 203). Here, if the above-mentioned operation (switch touch of the centralized operation switch 13) is performed before the interruption has elapsed for T1 seconds, the process proceeds to step 202, and the display of the currently displayed menu is maintained. If T1 seconds have elapsed after the interruption, the display of the second projection display device 12 is returned from the menu display to the tachometer display (step 204). Next, it is determined whether the interruption of the operation has elapsed for T2 seconds (step 205). The relationship between T1 and T2 is T1 <T2. For example, T1 is 5 seconds, and T2 is 10
It should be set to about seconds.

If the above operation is performed before the lapse of the operation T2 seconds, the display of the second projection display device 12 is switched from the tachometer display to the menu display of the hierarchy at the time of the interruption. (Step 206), and the process returns to Step 201. If the interruption of the operation has elapsed for T2 seconds, the display of the second projection display device 12 is switched from the tachometer display to the initial menu display (step 207), and the process returns to step 201 to interrupt the switch operation. Judge.

Therefore, in this embodiment, by touching the centralized operation switch provided at the driver's hand, the meter display on the display device is switched to the operation menu of each device, and the centralized operation switch can be moved up and down without looking at the operator. By moving the device left and right, the operation of each of the above devices becomes possible. That is, in this embodiment, since the switch is provided near the driver, the amount of movement of the driver's hand is reduced, and the operability can be improved. Further, in this embodiment, when the driver operates the switch, the position of the switch can be operated without the driver looking at the position, so that there is an effect that the driver's line of sight moves less. In this embodiment, since the touch sensor is added to the joystick switch, the driver's intention to operate can be quickly displayed.
