Control to reverse the motor M. The control unit is configured by the control unit 22 and the motor drive circuit 21.

Now, as shown in FIG.
When the vehicle 1 is traveling and there is an obstacle K ahead, in this state, the first sensor 16 does not detect the obstacle K, so the control unit 22 does not control the motor drive circuit 21 and the door mirror 14 is not shown. It remains in the state.

As shown in FIG. 3B, the obstacle K is detected by the first sensor 16 as the vehicle 11 travels.
When it comes inside, the first sensor 16 detects the obstacle K. In response to this detection, the control unit 22 controls the motor drive circuit 21 to rotate the motor M in the normal direction and store the door mirror 14.
By this storage, even if the obstacle K comes to the position shown in FIG. 3C, the obstacle K does not collide with the door mirror 14 and the door mirror 14 can be prevented from being damaged.

When the obstacle K comes to the position shown in FIG. 3D, the second sensor 17 detects the obstacle K, and the control unit 22 controls the motor drive circuit 21 to reverse the motor M. .
Due to the reverse rotation of the motor M, the door mirror 14 returns to the original predetermined position.

As described above, when the second sensor 17 detects the obstacle K, that is, when the obstacle K passes by, the door mirror 14 automatically returns to the original predetermined position, so that the door mirror 14 is returned to the original position. There is no need to perform manual operations.

When the second sensor 17 detects the obstacle K, its operation is stopped.

When the obstacle K is present at the position shown in FIG. 6A, the control unit 22 does not control the motor drive circuit 21 because the first sensor 16 has not detected the obstacle K. The door mirror 14 remains as shown. In addition, since the camera operation control unit 42 does not operate the camera control unit 41, the TV camera 30 does not start shooting and the monitor 32 does not display an image.

As the vehicle 11 runs, an obstacle K is generated as shown in FIG.
As shown in (B), when the first sensor 16 comes within the detection range S1 of the first sensor 16, the first sensor 16 detects the obstacle K. In response to this detection, the control unit 22 controls the motor drive circuit 21 to rotate the motor M in the normal direction and store the door mirror 14. On the other hand, the camera operation control unit 42 activates the camera control unit 41, the TV camera 30 starts shooting, and the monitor 32
An image captured by the V camera 30 is displayed.

The display on the monitor 32 allows the driver to know the distance between the obstacle K and the vehicle body 10 and to prevent the obstacle K from colliding with the vehicle body.

Further, since the door mirror 14 is stored, even if the obstacle K comes to the position shown in FIG. 6C, the obstacle K does not collide with the door mirror 14 and prevents the door mirror 14 from being damaged. Can be. Also at this time, since the obstacle K and the side of the vehicle body 10 are displayed on the monitor 32 by being photographed by the TV camera 30, it is possible to prevent the obstacle K from rubbing against the side of the vehicle body 10. . Also obstacles
