Next, the operation of instrument panel node 7 and column node 9 will be described with reference to the flowcharts of FIGS. In FIG. 3, the instrument panel node 7 has a left / right selection position 703L with the left / right selection operation unit 700 not set at the intermediate position 7030.
When the tilt operation unit 701 is set to “1”, a drive signal for the left rear-viewing mirror 4L is transmitted to the intermediate position.
When it is not set at 7030 or the left selection position 703L, that is, when it is set at the right selection position 703R, the drive signal of the right rear view mirror 4R is transmitted by operating the tilt operation unit 701.

On the other hand, the left / right selection operation section 700 is moved to the intermediate position 7030.
As described above, when the left and right (LR) tilt operation section of the tilt operation section 701 is operated, the left or right front combination lamp (turn lamp only) 21L or 21R and the rear lamp (rear turn lamp) are set. Only) 5L or 5R is transmitted with a flashing instruction signal. When the upper (U) portion of the up / down (UD) tilt operation portion is pressed, the drive signal of the wiper 80 is issued. When the lower (D) portion is pressed, the wiper 80 is pressed. To send a stop signal. The drive speed change signal of the wiper 80 can be transmitted according to the number of times the upper (U) portion of the up-down (UD) tilt operating portion is pressed, for example, intermittent operation when pressed once and normal when pressed twice. When pressed three times, a high-speed operation signal is transmitted.

In FIG. 4, the column node 9 determines whether or not the combination switch 90 has failed. When the combination node 90 is normal, the column node 9 transmits an operation signal by operating the combination switch 90. When the combination node 90 fails, the column node 9 transmits failure data of the combination switch 90. When the front nodes 6R and 6L receive the failure data of the combination switch 90, the blinking operation of the headlamps 20L and 20R is switched to the automatic mode, and the headlights 20L and 20R are switched based on the solar radiation detection data of the solar radiation sensor 100. Flashes.

With the above configuration, when the combination switch 90 fails, an operation signal of at least a part of the functions of the combination switch 90 is transmitted by the operation switch 7 for remotely controlling the rear-viewing mirrors 4L and 4R. Since transmission is performed via the multiplex transmission path, backup when the failure of the combination switch 90 can be achieved with a simple configuration without complicating the wiring.

In the operation shown in FIGS. 3 and 4, when the combination switch 90 is normal, the combination switch 90 and the operation switch 7 can output operation signals having the same function. By allowing the operation switch 7 to output an operation signal of at least a part of the functions of the combination switch 90 only when the combination switch 90 has failed, it is possible to eliminate the risk of performing an unnecessary operation unconsciously.

[0016]

Since the present invention is configured as described above, it has the following effects. When the combination switch fails, the operation signal of at least part of the function of the combination switch is transmitted by the operation switch for remotely controlling the rear view mirror, so that the wiring is not complicated and the configuration is simple. Backup can be achieved when the combination switch fails.
