Abstract

A display system is provided in a vehicle and includes: an HUD positioned inside the vehicle and configured so as to display, on the vehicle window, a surrounding environment video indicating the environment surrounding the vehicle; and a display control unit controlling the HUD such that the surrounding environment video is displayed on the window in accordance with prescribed conditions associated to the vehicle or the environment surrounding the vehicle and configured so as to reduce the transmittance of the window.

First claim

The invention claimed is:

1. A vehicle display system provided in a vehicle, the vehicle display system comprising:
a first display device located inside the vehicle and configured to display a surrounding environment image indicating a surrounding environment of the vehicle on a window of the vehicle; and
a display control unit configured to, according to a predetermined condition associated with the vehicle or the surrounding environment of the vehicle, control the first display device such that the surrounding environment image instead of a field of view visible to an occupant through the window is displayed on the window and lower a transmittance of the window.

2. The vehicle display system according to claim 1 ,
wherein the first display device is configured to display the surrounding environment image of a traveling direction of the vehicle on a front window of the vehicle.

3. The vehicle display system according to claim 1 ,
wherein the first display device is configured to display the surrounding environment image on all windows of the vehicle and lower a transmittance of each of all the windows.

4. The vehicle display system according to claim 1 , further comprising:
a second display device configured to emit a light pattern toward a road surface outside the vehicle,
wherein when the second display device emits the light pattern toward the road surface, the display control unit controls the first display device such that the surrounding environment image is displayed on the window, and lowers the transmittance of the window.

5. The vehicle display system according to claim 1 ,
wherein the display control unit controls the first display device such that the surrounding environment image is displayed on the window and lowers the transmittance of the window according to a driving mode of the vehicle.

6. The vehicle display system according to claim 1 ,
wherein the display control unit controls the first display device such that the surrounding environment image is displayed on the window and lowers the transmittance of the window according to a brightness of the surrounding environment of the vehicle.

7. The vehicle display system according to claim 1 ,
wherein the display control unit controls the first display device such that the surrounding environment image is displayed on the window and lowers the transmittance of the window according to a road on which the vehicle is currently traveling.

8. The vehicle display system according to claim 1 ,
wherein the display control unit controls the first display device such that the surrounding environment image is displayed on the window and lowers the transmittance of the window according to weather at a current position of the vehicle.

9. A vehicle comprising: the vehicle display system according to claim 1 .

10. A vehicle display system provided in a vehicle, the vehicle display system comprising:
a first display device configured to emit a light pattern indicating predetermined information toward a road surface outside the vehicle;
a second display device located inside the vehicle and configured to display vehicle traveling information on traveling of the vehicle toward an occupant of the vehicle such that the vehicle traveling information is superimposed on a real space outside the vehicle; and
a display control unit configured to, based on information on the vehicle or information on a surrounding environment of the vehicle, stop displaying of the predetermined information by the first display device and switch displaying of the predetermined information to the second display device, or stop displaying of the vehicle traveling information by the second display device and switch displaying of the vehicle traveling information to the first display device.

11. The vehicle display system according to claim 10 ,
wherein the display control unit causes the second display device to display the predetermined information based on the information on the vehicle or the information on the surrounding environment of the vehicle.

12. The vehicle display system according to claim 10 ,
wherein the display control unit causes the first display device to display the vehicle traveling information based on the information on the vehicle or the information on the surrounding environment of the vehicle.

13. The vehicle display system according to claim 10 ,
wherein the display control unit causes the second display device to display a part of the predetermined information based on the information on the vehicle or the information on the surrounding environment of the vehicle.

14. The vehicle display system according to claim 10 ,
wherein the information on the vehicle refers to information on a driving mode of the vehicle.

15. The vehicle display system according to claim 10 ,
wherein the information on the surrounding environment of the vehicle refers to brightness information of the surrounding environment, road information on the road on which the vehicle is currently traveling, or weather information at a current position of the vehicle.
