Abstract

An autonomous vehicle includes a vehicle body, at least one detector, at least one display and at least one controller. The at least one detector is configured to detect a presence of an external object within a vicinity of the vehicle. The at least one display is supported on the vehicle body. The at least one controller is programmed to determine the presence of the external object upon detection of the external object by the detector. The controller is further programmed to display a rationale indicator on the display to a remote party within the vicinity of the vehicle based on a detection result of the detector indicating the presence of the external object. The rationale indicator is an indication of an external condition occurring in the vicinity of the vehicle.

Claims

1. An autonomous vehicle comprising:

a vehicle body;

at least one detector configured to detect a presence of an external object within a vicinity of the vehicle;

at least one display supported exteriorly on the vehicle body; and

at least one controller programmed to determine the presence of the external object upon detection of the external object by the detector and to display a rationale indicator on the display to a remote party within the vicinity of the vehicle based on a detection result of the at least one detector indicating the presence of the external object, the rationale indicator being an indication of a presence of an external object that is detected to be in the vicinity of the vehicle.

2. The autonomous vehicle according to claim 1, further comprising

a vehicle location positioning system in communication with the at least one controller, the at least one controller being programmed to determine that the vehicle is in proximity to at least one of an intersection and a crosswalk based on a vehicle location provided by the vehicle location positioning system, the detector being initiated upon approaching at least one of the intersection and the crosswalk.

3. The autonomous vehicle according to claim 1, wherein

the at least one detector is configured to undergo continuous detection of the vicinity of the vehicle to determine the presence of the external object upon starting the autonomous vehicle.

4. The autonomous vehicle according to claim 1, wherein

the at least one detector is configured to detect a plurality of external objects within the vicinity of the vehicle upon starting the autonomous vehicle.

5. The autonomous vehicle according to claim 1, wherein

the at least one controller is programmed to display the rationale indicator on the display upon determining that the external condition is a state in which the external object is an obstacle in a travel path of the vehicle, the rationale indicator being indicative of the state.

6. The autonomous vehicle according to claim 1, wherein

the at least one controller is programmed to display the rationale indicator on the display upon determining that the external condition of the vehicle surroundings includes a state in which the external object is an obstacle approaching a travel path of the vehicle, the rationale indicator being indicative of the state.

7. The autonomous vehicle according to claim 1, wherein

the at least one controller is programmed to display the rationale indicator on the display upon determining that the external condition of the vehicle surroundings includes a state in which the external object is an obstacle adjacent a travel path of the vehicle, the rationale indicator being indicative of the state.

8. The autonomous vehicle according to claim 1, wherein

the at least one display includes a plurality of displays supported on the vehicle body.

9. The autonomous vehicle of claim 8, wherein

the at least one controller is programmed to display at least one image on the display indicative of an external condition to convey the rationale of the rationale indicator.

10. The autonomous vehicle according to claim 8, wherein

the at least one controller is programmed to display lights on the display in a direction along the display screen that corresponds to a direction of movement of the external object on the display.

11. The autonomous vehicle according to claim 10, wherein

the at least one controller is programmed to display the lights with a plurality of colors.

12. The autonomous vehicle according to claim 8, wherein

the at least one controller is programmed to display a moving image on at least one of the plurality of displays corresponding to a movement of the external object as the rationale indicator.

13. The autonomous vehicle according to claim 8, wherein

the plurality of displays includes a first display being configured to display a first rationale indicator, and a second display being configured to display a second rationale indicator that is different from the first rationale indicator.

14. The autonomous vehicle according to claim 13, wherein

the controller is programmed to simultaneously display the first rationale indicator on the first display and the second rationale indicator on the second display.

15. The autonomous vehicle according to claim 1, wherein

the at least one display is located on area of the vehicle body visible to the remote party that includes at least one of another driver, a pedestrian, and a cyclist within the vicinity of the vehicle as the remote party.

16. The autonomous vehicle according to claim 1, wherein

the at least one detector configured to detect a at least one of another driver, a pedestrian, and a cyclist within the vicinity of the vehicle as the external object.

17. An autonomous vehicle comprising:

a vehicle body;

at least one detector configured to detect a presence of an external object within a vicinity of the vehicle;

a plurality of displays supported at various exterior locations of the vehicle body; and

at least one controller programmed to determine the presence of the external object upon detection of the external object by the at least one detector and to display a rationale indicator that indicates the presence of the external object to a remote party on at least a first display of the plurality of displays, the controller being further programmed to select the first display based on a determination that the external object is substantially within an obstructed viewing area from the perspective of the remote party.

18. The autonomous vehicle according to claim 17, wherein

the at least one controller is programmed to display the rationale indicator on the first display to convey a condition of the obstructed viewing area to the remote party.
