Abstract

A control device outputs control information to a sidewalk configured such that an inclination of a road surface is changeable. When the control device detects a wheelchair waiting on the sidewalk for crossing a road, the control device outputs, as the control information, information of instruction to reduce the inclination of the road surface of the sidewalk.

First claim

What is claimed is:

1. A control device that outputs control information to a sidewalk configured such that an inclination of a road surface is changeable, wherein when the control device detects a wheelchair waiting on the sidewalk for crossing a road, the control device outputs, as the control information, information of instruction to reduce the inclination of the road surface of the sidewalk.

2. The control device according to claim 1 , wherein when the control device detects the wheelchair that crosses the road, a pedestrian crossing is displayed on the road.

3. The control device according to claim 2 , wherein when the pedestrian crossing is displayed, the control device outputs, as the control information, information of instruction to incline the road surface of the sidewalk on which the wheelchair waits before crossing toward the road.

4. The control device according to claim 1 , wherein when the wheelchair starts crossing the road, the control device outputs, as the control information, information of instruction to incline the road surface of the sidewalk on which the wheelchair waits before crossing toward the road.

5. The control device according to claim 3 , wherein after the wheelchair leaves a position where the wheelchair was waiting before crossing, the control device outputs, as the control information, information of instruction to restore the inclination of the road surface at a waiting position to an original inclination.

6. The control device according to claim 1 , wherein the control device detects, as the wheelchair that crosses the road, a wheelchair that stays on the sidewalk for a predetermined time or longer or a wheelchair that outputs information of application for crossing the road.

7. The control device according to claim 1 , wherein the control device determines a position where the wheelchair waits before crossing and notifies the wheelchair of the position.

8. The control device according to claim 7 , wherein the control device displays the position where the wheelchair waits before crossing.

9. The control device according to claim 1 , wherein when the control device changes the inclination of the road surface, the control device notifies the wheelchair or a person who is located within a predetermined range from the road surface, of a change in the inclination of the road surface.

10. The control device according to claim 9 , wherein the control device notifies a terminal device mounted on the wheelchair waiting on the sidewalk or carried by a user sitting in the wheelchair waiting on the sidewalk, of the change in the inclination of the road surface.

11. The control device according to claim 1 , wherein the control device detects the wheelchair waiting on the sidewalk based on information acquired from a terminal device mounted on the wheelchair waiting on the sidewalk or carried by a user sitting in the wheelchair waiting on the sidewalk.

12. A control system comprising:
the control device according to claim 1 ; and
a road surface drive device that changes the inclination of the road surface of the sidewalk.

13. A control method comprising outputting, as control information, information of instruction to reduce an inclination of a road surface of a sidewalk, to the sidewalk configured such that the inclination of the road surface is changeable, when a wheelchair waiting on the sidewalk for crossing the road is detected.

14. The control method according to claim 13 , further comprising displaying a pedestrian crossing on the road, when the wheelchair that crosses the road is detected.

15. The control method according to claim 14 , further comprising outputting, as the control information, information of instruction to incline the road surface of the sidewalk on which the wheelchair waits before crossing, toward the road, when the pedestrian crossing is displayed.

16. The control method according to claim 13 , further comprising outputting, as the control information, information of instruction to incline the road surface of the sidewalk on which the wheelchair waits before crossing toward the road, when the wheelchair starts crossing the road.

17. The control method according to claim 15 , further comprising outputting, as the control information, information of instruction to restore the inclination of the road surface at a waiting position to an original inclination, after the wheelchair leaves a position where the wheelchair was waiting before crossing.

18. A road surface drive device that controls an inclination of a road surface, the road surface drive device comprising:
a base that constitutes the road surface;
a drive unit that drives the base; and
a control unit that controls the drive unit so as to change the inclination of the road surface based on control information that indicates a direction and a magnitude of the inclination of the road surface.

19. The road surface drive device according to claim 18 , wherein the control unit notifies surroundings of a change in the inclination of the road surface.

20. The road surface drive device according to claim 18 , wherein the control unit outputs a detection result of a wheelchair waiting on the road surface.
