The control device 32 controls the moving device 30 based on information such as the value of the traveling speed of the vehicle 12 and the operation by the driver of the operation lamp 19 of the direction indicator lamp. When the main switch of the vehicle 12 is turned on, the control device 32 sends an operation signal to the moving device 30 and opens the display 22 left and right as shown in FIG. 1 from the folded state as shown in FIG. At the same time, the display 22 is moved to a reference position substantially at the center of the guide rail 34. Such a state is shown in FIGS. The state in which the display device 22 is arranged at substantially the center height of the meter panel 18 in this way is the state in which the display device 22 is set to the first stage (reference position).

  When the traveling speed of the vehicle 12 exceeds the threshold value, the control device 32 sends an operation signal to the moving device 30 to move the display 22 forward of the vehicle 12. FIG. 7 shows a state where the display 22 has moved forward. As shown in FIG. 7, the state in which the indicator 22 is disposed in front of the vehicle 12 is the state in which the indicator 22 is set in the second stage.

  The indicator 22 set in the second stage is located above the position of the indicator 22 set in the first stage, and the interval between the right indicator 22a and the left indicator 22b is the first stage. It is narrower.

  On the other hand, when the driver sets the transmission of the vehicle 12 to the reverse reverse gear, the control device 32 sends an operation signal to the moving device 30 and moves the indicator 22 to the rear of the vehicle 12, that is, to the driver's seat 20 side. . FIG. 8 shows a state where the display 22 is moved backward. As shown in FIG. 8, the state in which the indicator 22 is arranged behind the vehicle 12 is a state in which the indicator 22 is set in the third stage.

  The indicator 22 set in the third stage is positioned below the position of the indicator 22 set in the first stage, and the right and left distance between the right indicator 22a and the left indicator 22b is the first stage. It has been expanded.

  Furthermore, when the indicator 22 is set to the first stage or the second stage, when the operation lamp 19 of the direction indicator lamp is operated by the driver, the control device 32 sends an operation signal to the moving device 30. The indicator 22 on the side where the direction indicator lamp operates is moved.

  For example, when the driver operates the control rod 19 to make a right turn or a lane change to the right lane (which changes the course), the control device 32 sends an operation signal to the moving device 30 and the right indicator 22a. Is moved to the third stage. Similarly, when the driver tries to turn left or change the lane to the left lane and operates the control rod 19, the control device 32 sends an operation signal to the moving device 30 and moves the left indicator 22b to the third stage. Let

  Next, functions and effects 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 indicator 22 is opened as shown in FIGS. 1 and 3, and the indicator 22 is in the first stage. It is arranged in the state.

  An image captured by the right camera 26a is displayed on the right display 22a, and an image captured by the left camera 26b is displayed on the left display 22b. As a result, the right indicator 22a displays the situation on the right rear side of the vehicle 12 indicated by the hatched area a in FIG. 2, and the left indicator 22b displays the rear left of the vehicle 12 indicated by the hatched area b. The side status is displayed.

  While the driver is looking at the front of the vehicle 12 while driving, the speed meter and the indicator 22 of the meter panel 18 are within the range of view, so that the direction of the line of sight is not greatly changed. The situation on the rear side of the vehicle 12 can be visually recognized through the display 22 together with the front state.

  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 placed in the second stage state. When the traveling speed of the vehicle 12 is increased, the driver has a far focus on the eyes, and the field of view narrows around the direction of the line of sight. As shown in FIG. 7, the display device 22 set in the second stage is disposed at a high position in front and the interval between the right display device 22a and the left display device 22b is narrowed. As a result, even when the driver's focus is far away due to high-speed driving and the field of view is narrowed, the driver can easily visually recognize the image displayed on the display 22 without greatly moving his / her line of sight. .

  In addition, when the vehicle is traveling at a low or medium speed in the first stage or at a high speed in the second stage, it is desired to turn right or left or change the lane. 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 in either the right or left turn or the left or right direction to change the lane is set to the third stage. In other words, when the operation lamp 19 of the direction indicator lamp is operated to turn right in the first stage state, 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. Arranged in the third stage.

  As a result, when the driver moves his / her line of sight in the right turn direction, the right indicator 22a moves to the right, so the driver displays the image displayed on the right indicator 22a without moving his / her line of sight greatly. Can be easily recognized. Further, since the right indicator 22a moves toward 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 the operating rod 19 is operated to change to the right lane while traveling at a high speed, the right indicator 22a is arranged at the third stage as shown in FIG. The driver can easily visually recognize the image displayed on the right display 22a without moving it greatly. The same applies when turning left or changing to the left lane.

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

  In the above example, when the traveling speed of the vehicle 12 exceeds the threshold value, the indicator 22 is moved to the second stage. However, the indicator 22 is continuously moved according to the fluctuation of the traveling speed. Also good. In the above example, the imaging device 26 is provided in the side mirror 24. However, the imaging device 26 may be provided in 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. You may use for the vehicle which confirms the rear side of the vehicle 12 with the imaging device 26 and the indicator 22. FIG.

  The present invention can be used for a video display device of a vehicle.
