Abstract

A vehicle having a road-surface rendering function includes a light projection member, a control unit, and a detection device. The light projection member is configured to perform light projection for road-surface rendering at least toward a road surface ahead of the vehicle. The control unit is configured to control the light projection for the road-surface rendering by the light projection member. The detection device is configured to perform detection of the road surface onto which the light projection member performs the light projection for the road-surface rendering. The control unit is configured to perform control to suppress the light projection for the road-surface rendering by at least determining insufficient reflection in the road-surface rendering in the vehicle based on the detection of the road surface by the detection device.

Claims (44)

1. A vehicle having a road-surface rendering function, the vehicle comprising:

a light projection member configured to perform light projection for road-surface rendering at least toward a road surface ahead of the vehicle;

a control unit configured to control the light projection for the road-surface rendering by the light projection member; and

a detection device configured to perform detection of the road surface onto which the light projection member performs the light projection for the road-surface rendering,

wherein the control unit is configured to perform control to suppress the light projection for the road-surface rendering by at least determining insufficient reflection in the road-surface rendering in the vehicle based on the detection of the road surface by the detection device.

2. The vehicle having the road-surface rendering function according to claim 1 ,

wherein the detection device is configured to detect, as a detection image, an image rendered in accordance with the light projection on the road surface, and

wherein the control unit is configured to:

determine an insufficient reflection area in the detection image detected by the detection device with respect to the road-surface rendering; and

when the insufficient reflection area has occurred, suppress the light projection for the road-surface rendering from the light projection member.

3. The vehicle having the road-surface rendering function according to claim 2 ,

wherein the control unit is configured to:

compare the detection image detected by the detection device with a light projection pattern projected by the light projection member; and

determine whether the detection image that is not entirely inconsistent with the light projection pattern has the insufficient reflection area exists in.

4. The vehicle having the road-surface rendering function according to claim 3 ,

wherein the control unit is configured to:

when the detection image detected by the detection device has the insufficient reflection area, determine a relationship that the insufficient reflection area has with the light projection pattern, and

when a main area of the light projection pattern is rendered, suppress the light projection for the road-surface rendering by reducing the light projection toward the insufficient reflection area.

5. The vehicle having the road-surface rendering function according to claim 4 , further comprising:

a headlamp member configured to project light forward of the vehicle,

wherein the control unit is configured to perform control for suppressing the light projection for the road-surface rendering by at least predicting and determining insufficient reflection in the road-surface rendering based on the detection by the detection device with respect to the road surface receiving the light projected by the headlamp member.

6. The vehicle having the road-surface rendering function according to claim 5 ,

wherein the control unit is configured to at least predict and determine the insufficient reflection in the road-surface rendering by determining the insufficient reflection with respect to the road surface in a light projection range of the headlamp member located forward of the vehicle in a traveling direction of the vehicle relative to a road-surface position onto which the light projection member performs the light projection for the road-surface rendering.

7. The vehicle having the road-surface rendering function according to claim 2 , further comprising:

a headlamp member configured to project light forward of the vehicle,

wherein the control unit is configured to perform control for suppressing the light projection for the road-surface rendering by at least predicting and determining insufficient reflection in the road-surface rendering based on the detection by the detection device with respect to the road surface receiving the light projected by the headlamp member.

8. The vehicle having the road-surface rendering function according to claim 7 ,

wherein the control unit is configured to at least predict and determine the insufficient reflection in the road-surface rendering by determining the insufficient reflection with respect to the road surface in a light projection range of the headlamp member located forward of the vehicle in a traveling direction of the vehicle relative to a road-surface position onto which the light projection member performs the light projection for the road-surface rendering.

9. The vehicle having the road-surface rendering function according to claim 3 , further comprising:

a headlamp member configured to project light forward of the vehicle,

wherein the control unit is configured to perform control for suppressing the light projection for the road-surface rendering by at least predicting and determining insufficient reflection in the road-surface rendering based on the detection by the detection device with respect to the road surface receiving the light projected by the headlamp member.

10. The vehicle having the road-surface rendering function according to claim 9 ,

wherein the control unit is configured to at least predict and determine the insufficient reflection in the road-surface rendering by determining the insufficient reflection with respect to the road surface in a light projection range of the headlamp member located forward of the vehicle in a traveling direction of the vehicle relative to a road-surface position onto which the light projection member performs the light projection for the road-surface rendering.

11. The vehicle having the road-surface rendering function according to claim 1 , further comprising:

a headlamp member configured to project light forward of the vehicle,

wherein the control unit is configured to perform control for suppressing the light projection for the road-surface rendering by at least predicting and determining insufficient reflection in the road-surface rendering based on the detection by the detection device with respect to the road surface receiving the light projected by the headlamp member.

12. The vehicle having the road-surface rendering function according to claim 11 ,

wherein the control unit is configured to at least predict and determine the insufficient reflection in the road-surface rendering by determining the insufficient reflection with respect to the road surface in a light projection range of the headlamp member located forward of the vehicle in a traveling direction of the vehicle relative to a road-surface position onto which the light projection member performs the light projection for the road-surface rendering.

13. A vehicle having a road-surface rendering function, the vehicle comprising:

a light projection member including a light source and configured to perform light projection for road-surface rendering at least toward a road surface ahead of the vehicle; and

circuitry configured to

control the light projection for the road-surface rendering by the light projection member,

perform detection of the road surface onto which the light projection member performs the light projection for the road-surface rendering, and

perform control to suppress the light projection for the road-surface rendering by at least determining insufficient reflection in the road-surface rendering in the vehicle based on the detection of the road surface.
