The position of the upper edge portion 141 of the projection range 140 in the vertical direction is displaced according to the vehicle speed.
This point will be described in detail below.

FIG. 3 is a flowchart showing the operation of the display device of the first embodiment.
Hereinafter, each step will be described step by step.

<Step S01: Vehicle speed detection>
The projection range setting device 40 detects the current vehicle speed of the own vehicle based on the vehicle speed pulse signal transmitted from the vehicle speed sensor 50.
Then, the process proceeds to step S02.

<Step S02: Determination of the upper end position of the projection range>
In the projection range setting device 40, the position of the upper edge portion 141 of the projection range 140 currently set is a low position for low-speed traveling (indicated by a broken line in FIGS. 2 and 4), or is used for high-speed traveling. It is determined whether the position is high (shown by a solid line in FIGS. 2 and 4).
If the position of the upper edge portion 141 is low, the process proceeds to step S03, and if the position of the upper edge portion 141 is high, the process proceeds to step S04.

<Step S03: Vehicle speed judgment 1>
The projection range setting device 40 determines whether or not the current vehicle speed V is equal to or higher than a preset threshold value Vu.
When the vehicle speed V is equal to or higher than the threshold value Vu, the process proceeds to step S04 to raise the upper edge portion 141, and when the vehicle speed V is lower than the threshold value Vu, the upper edge portion 141 is maintained in a low position and a series of processes is completed.

<Step S04: Raise the upper end position of the projection range>
The projection range setting device 40 changes the set position of the upper edge portion 141 of the projection range 140 from the current low position to the high position.
The projection range setting device 40 transmits a signal instructing the image generation device 20 and the head-up display device 30 to displace the upper edge portion 141 to a high position.
As a result, the projection range 140 is enlarged by raising the upper edge portion 141, and the range visible to the naked eye by the occupant through the windshield 110 is partially shielded and reduced (restricted).
At this time, the expanded range of the projection range 140 is set to a position where the area closest to the own vehicle in the field of view through the windshield 110 is shielded when viewed from the viewpoint position of the occupant.
After that, a series of processes is completed.

<Step S05: Vehicle speed judgment 2>
The projection range setting device 40 determines whether or not the current vehicle speed V is equal to or less than a preset threshold value Vd (Vd <Vu).
When the vehicle speed V is equal to or less than the threshold value Vu, the process proceeds to step S06 in order to lower the upper edge portion 141, and when the vehicle speed V exceeds the threshold value Vd, the upper edge portion 141 maintains a high position and ends a series of processes.

<Step S06: Raise the upper end position of the projection range>
The projection range setting device 40 changes the set position of the upper edge portion 141 of the projection range 140 from the current high position to the low position.
The projection range setting device 40 transmits a signal instructing the image generation device 20 and the head-up display device 30 to displace the upper edge portion 141 to a lower position.
As a result, the projection range 140 is reduced by lowering the upper edge portion 141, and the range visible to the naked eye by the occupant through the windshield 110 is expanded.
After that, a series of processes is completed.

FIG. 4 is a diagram schematically showing an example of a display image in the display device of the first embodiment.
As shown in FIG. 4, the display image 200 is generated as an image (front image referred to in the present invention) showing the situation in front of the own vehicle based on the image obtained by capturing the front of the own vehicle.
As the display image 200, a live image obtained by performing predetermined image processing on the image captured by the camera 10 or computer graphics generated based on the image captured by the camera 10 can be used.
In the example shown in FIG. 4, the display image 200 displays the horizontal line H, the own vehicle traveling lane 201, the oncoming lane 202, the white lines 203, 204, 205 and the like.
In addition, if there are preceding vehicles, oncoming vehicles, pedestrians, buildings, terrain, signs, traffic lights, etc., these images are also displayed.

When the vehicle speed V becomes equal to or higher than the threshold value Vu and the upper edge portion 141 of the projection range 140 rises, the display image 200 is self-masked in a band shape at the left and right end portions and the lower end portion as shown by the broken line in FIG. The image in front of the vehicle is not displayed, and the field of view (display range / angle of view) of the display image 200 is reduced.

Further, in the region below the horizontal line H in the display image 200, a dividing line L that divides the display image 200 into upper and lower parts is set.
The dividing line L is arranged along the horizontal direction, for example.
In the display image 200, in the region below the dividing line L, the refresh rate, which is the frequency of image update, is lower than that in the region above (the update frequency becomes sparse).
Further, the region below the dividing line L may be displayed (wide-angle) so that the display magnification is smaller than that of the region above.

According to the first embodiment described above, the following effects can be obtained.
(1) At high speeds where it is preferable to limit the immediate field of view of the own vehicle, the occupant can visually see the front of the own vehicle by shifting the position of the upper edge 141 of the projection range 140 upward. It is possible to moderately limit the field of vision and prevent excessive sense of speed and the accompanying fear.
In addition, by setting the projection range 140 at a location where the visual field is obstructed by the naked eye, it is possible to visually recognize the information projected by the movement of the line of sight with a small number of occupants.
(2) By displaying the image in front of the own vehicle in the projection range 140, even if a part of the field of view that can be seen with the naked eye is obstructed by the projected image, the occupant can monitor the front of the own vehicle. You can display the necessary information.
(3) By masking the peripheral part of the display image of the projection range 140 according to the increase in vehicle speed and reducing the field of view, the line of sight of the occupant is guided to the area where attention is required during high-speed driving, and the line of sight of the occupant is excessively wide. Appropriate information can be displayed by not showing the information.
(4) By lowering the refresh rate of the region below the dividing line L in the display image 200 with respect to the region above, it is possible to prevent the subject from appearing excessively fast in the field of view immediately before the own vehicle. It is possible to prevent giving a feeling of fear to the occupants.
Further, the same effect can be obtained when the region below the dividing line L is displayed at a wide angle (low magnification display).

The display device 90 is attached so as to be displaceable in the vertical direction with respect to the instrument panel 120.

The display elevating drive device 91 drives the display device 90 so as to be displaced in the vertical direction with respect to the instrument panel 120.
The display elevating drive device 91 is configured to include, for example, a motor, a reduction gear train, a conversion mechanism for converting rotational motion into vertical translational motion, and the like.

The display position setting device 100 sets the position of the display device 90 in the vertical direction.
The display position setting device 100 controls the display elevating drive device 91 to displace the display device 90 in the vertical direction according to the vehicle speed V detected by the vehicle speed sensor 50.
The display device 90 increases when the vehicle speed V is equal to or higher than the threshold value Vr, and decreases when the vehicle speed V is equal to or lower than the threshold value Vd, substantially similar to the position of the upper edge portion 141 of the projection range 140 in the first embodiment. ..
