Abstract

This display system which is provided in a vehicle comprises: a road surface drawing device that is configured so as to emit a light pattern (L 1 ) toward a road surface outside the vehicle; an HUD that is located inside the vehicle and configured so as to display HUD information to an occupant of the vehicle such that the HUD information is overlaid on real space outside the vehicle; and a display control unit that is configured so as to control the road surface drawing device. The display control unit is configured so as to control the emission of the light pattern (L 1 ) in accordance with an input operation by the occupant in an HUD display area (D 1 ) where the HUD information can be displayed.

First claim

The invention claimed is:

1. A display system for a vehicle, comprising:
at least one road surface drawing device, arranged in at least one headlamp of the vehicle, configured to emit at least one light pattern toward a road surface outside the vehicle;
a head up display (HUD) device, located inside the vehicle, configured to:
display traveling information of the vehicle,
display surrounding environment information of the vehicle, and
superimpose the traveling information of the vehicle and the surrounding environment information of the vehicle, on a real space, outside the vehicle; and

a display controller configured to control:
operations of the road surface drawing device and the HUD device,
emission of the light pattern, by the road surface drawing device, while the road surface drawing device is operating free of abnormality,
displaying, by the HUD device, the traveling information of the vehicle and the surrounding environment information of the vehicle while the HUD device is operating free of abnormality,
superimposing, by the HUD device, the traveling information of the vehicle and the surrounding environment information of the vehicle, on the real space outside the vehicle, while the HUD device is operating free of abnormality,
displaying, by the HUD device, the traveling information of the vehicle, the surrounding environment information of the vehicle, and information related to the light pattern while the road surface drawing device is operating with abnormality,

wherein the information related to the light pattern is different from the light pattern, and
wherein the information related to the light pattern includes character information or figure information which is not included in the light pattern.

2. The vehicle display system according to claim 1 ,
wherein while the road surface drawing device is operating with the abnormality, the road surface drawing device is further configured to emit a plurality of light patterns, and
wherein the display controller is further configured to control displaying, by the HUD device, information related to each one of the plurality of light patterns.

3. The vehicle display system according to claim 1 , wherein the display controller is further configured to control displaying, by the HUD device, the abnormality of the road surface drawing device.

4. The vehicle display system according to claim 1 , wherein while the HUD device is operating with the abnormality, the display controller is further configured to control emission, by the road surface drawing device, of the light pattern and information related to the traveling information of the vehicle and the surrounding environment information of the vehicle.

5. A display system for a vehicle, comprising:
at least one road surface drawing device, arranged in at least one headlamp of the vehicle, configured to emit at least one light pattern toward a road surface outside the vehicle;
a head up display (HUD) device, located inside the vehicle, configured to:
display at least one traveling information of the vehicle,
display surrounding environment information of the vehicle, and
superimpose the traveling information of the vehicle and the surrounding environment information of the vehicle, on a real space, outside the vehicle; and

a display controller configured to control:
operations of the road surface drawing device and the HUD device,
emission of the light pattern, by the road surface drawing device, while the HUD device is operating free of abnormality,
displaying, by the HUD device, the traveling information of the vehicle and the surrounding environment information of the vehicle while the HUD device is operating free of abnormality,
superimposing, by the HUD device, the traveling information of the vehicle and the surrounding environment information of the vehicle, on the real space outside the vehicle, while the HUD device is operating free of abnormality,
displaying, by the road surface drawing device, the light pattern and information related to the traveling information of the vehicle and the surrounding environment information of the vehicle while the HUD device is operating with abnormality,

wherein the information related to the traveling information of the vehicle and the surrounding environment information of the vehicle is different from the light pattern, and
wherein the information related to the traveling information of the vehicle and the surrounding environment information of the vehicle includes character information or figure information which is not included in the light pattern.

6. The vehicle display system according to claim 5 ,
wherein while the HUD device an is operating with the abnormality, the HUD device is further configured to display a plurality of traveling information of the vehicle and surrounding environment information of the vehicle,
wherein the display controller is further configured to control displaying, by the road surface drawing device, information related to the plurality of traveling information of the vehicle and the surrounding environment information of the vehicle.
