Next, the operation and effect of the vehicle display device 10 will be described. When the main switch of the vehicle 12 is off, the indicator 22 is folded from the pedestal 36 as shown in FIG. When the main switch of the vehicle 12 is turned on, an operation signal is sent from the control device 32 to the moving device 30, the display 22 is opened as shown in FIGS. 1 and 3, and the display 22 is in the first stage. It is arranged in the state of.

The right display 22a displays the image captured by the right camera 26a, and the left display 22b displays the image captured by the left camera 26b. As a result, the right display 22a displays the situation on the right rear side of the vehicle 12 shown by the shaded area a in FIG. 2, and the left display 22b shows the left rear side of the vehicle 12 shown by the shaded area b. The side situation is displayed.

While the driver is looking ahead of the vehicle 12 while driving, the speedometer of the meter panel 18 and the display 22 are within the range of the field of view, so that the direction of the line of sight of the vehicle 12 is not significantly changed. In addition to the front state, the situation of the rear side of the vehicle 12 can be visually confirmed through the display 22.

When the traveling speed of the vehicle 12 exceeds the threshold value, an operation signal is sent from the control device 32 to the moving device 30, and the indicator 22 is arranged in the second stage state. When the traveling speed of the vehicle 12 becomes high, the focus of the driver becomes distant, and the field of view of the driver becomes narrow around the direction of the line of sight. As shown in FIG. 7, the display 22 set in the second stage is arranged in a front and high position, and the distance between the right display 22a and the left display 22b is narrowed. As a result, even if the driver's focus becomes distant and the field of view is narrowed due to high-speed traveling, the driver can easily visually recognize the image displayed by the display unit 22 without significantly moving the line of sight. ..

In addition, while trying to make a right or left turn or change lanes from either the low-medium speed running of the first stage or the high speed running of the second stage, the operating rod of the turn signal lights 19 Is operated by the driver. Then, an operation signal is sent from the control device 32 to the moving device 30, and the indicator 22 for either the right turn or the left turn or the left or right direction to change the lane is set to the third stage. That is, when the operation rod 19 of the turn signal lamp is operated to turn right in the state of the first stage, as shown in FIG. 9, the left indicator 22b remains unchanged in the first stage and the position of the right indicator 22a is changed. Placed in the third stage.

As a result, when the driver moves the line of sight in the direction of making a right turn, the right display 22a is moving in the right direction, so the image displayed by the right display 22a without the driver moving the line of sight greatly. Can be easily seen. Further, since the right indicator 22a moves to the rear of the vehicle 12, that is, toward the driver, the right indicator 22a is emphasized and the visibility of the displayed image is improved.

Similarly, when operating the operating rod 19 to change to the right lane while traveling at high speed, the right display 22a is arranged in the third stage as shown in FIG. The driver can easily visually recognize the image displayed on the right display 22a without moving the driver largely. The same applies when making a left turn or changing to the left lane.

Further, when the driver sets the transmission gear to the reverse gear in an attempt to move the vehicle 12 backward, an operation signal is sent from the control device 32 to the moving device 30, and the indicator 22 is displayed in the third stage as shown in FIG. Is placed. As a result, when the driver confirms the outside or the rear of the vehicle 12, the distance between the right display 22a and the left display 22b is widened to the outside, so that the driver does not move his or her line of sight greatly. The image displayed by 22 can be easily visually recognized.

In the above example, when the traveling speed of the vehicle 12 exceeds the threshold value, the display 22 is moved to the second stage. However, the display 22 is continuously moved according to the change in the traveling speed. Is also good. Further, in the above example, the image pickup device 26 is provided on the side mirror 24, but the image pickup device 26 may be provided at any part of the vehicle 12 as long as the rear side of the vehicle 12 can be imaged, and the side mirror 24 is eliminated.
