Abstract

A system for gathering perception-data includes a transceiver and a controller-circuit. The transceiver is for installation on a host-vehicle. The transceiver is configured to receive perception-data from a perception-sensor installed on an assisting-vehicle proximate to the host-vehicle. The controller-circuit is in communication with the transceiver. The controller-circuit is configured to determine a preferred-perspective for gathering perception-data by the perception-sensor of the assisting-vehicle, and operate the transceiver to transmit a path-request to the assisting-vehicle that changes a planned-path of the assisting-vehicle to move the perception-sensor of the assisting-vehicle to the preferred-perspective.

First claim

What is claimed is:

1. A system comprising a controller circuit configured to:
determine a preferred perspective location of a perception sensor of an assisting vehicle;
transmit, from a host vehicle and to the assisting vehicle, a path request to move the assisting vehicle with the perception sensor to the preferred perspective location; and
receive, by the host vehicle and from the assisting vehicle, perception data gathered by the perception sensor from the preferred perspective location.

2. The system of claim 1 , wherein the controller circuit is configured to determine the preferred perspective location relative to a location of an object that obstructs an object detector of the host vehicle.

3. The system of claim 1 , wherein the controller circuit is configured to determine the preferred perspective location relative to a coordinate of a mapped object identified in a digital map.

4. The system of claim 1 , wherein the controller circuit is configured to determine the preferred perspective location in accordance with a contour of a roadway traveled by the host vehicle.

5. The system of claim 1 , wherein the perception data comprises control points characteristic of a travel lane proximate to the host vehicle.

6. The system of claim 1 , wherein the path request to move the perception sensor to the preferred perspective location configures the assisting vehicle to change a planned path of the assisting vehicle to move the perception sensor to the preferred perspective location.

7. The system of claim 6 , wherein the path request to move the perception sensor to the preferred perspective location configures the assisting vehicle to steer, accelerate, or decelerate to change the planned path of the assisting vehicle to move the perception sensor to the preferred perspective location.

8. A method comprising:
determining, by a controller circuit of a host vehicle, a preferred perspective location of a perception sensor of an assisting vehicle;
transmitting, by the controller circuit and to the assisting vehicle, a path request to move the perception sensor to the preferred perspective location; and
receiving, by the controller circuit and from the assisting vehicle, perception data gathered by the perception sensor from the preferred perspective location.

9. The method of claim 8 , further comprising:
determining the preferred perspective location relative to a location of an object that obstructs an object detector of the host vehicle.

10. The method of claim 8 , further comprising:
determining the preferred perspective location relative to a coordinate of a mapped object identified in a digital map.

11. The method of claim 8 , further comprising:
determining the preferred perspective location in accordance with a contour of a roadway traveled by the host vehicle.

12. The method of claim 8 , wherein the perception data comprises control points characteristic of a travel lane proximate to the host vehicle.

13. The method of claim 8 , wherein transmitting the path request to move the perception sensor to the preferred perspective location comprises:
transmitting the path request to change a planned path of the assisting vehicle to move the perception sensor to the preferred perspective location.

14. The method of claim 8 , wherein transmitting the path request to move the perception sensor to the preferred perspective location comprises:
transmitting the path request to cause the assisting vehicle to steer, accelerate, or decelerate to move the perception sensor to the preferred perspective location.

15. A system for a host vehicle, the system comprising:
means for determining a preferred perspective location of a perception sensor of an assisting vehicle;
means for transmitting, to the assisting vehicle, a path request to move the perception sensor to the preferred perspective location; and
means for receiving, from the assisting vehicle, perception data gathered by the perception sensor from the preferred perspective location.

16. The system of claim 15 , further comprising:
means for determining the preferred perspective relative to a location of an object that obstructs an object detector of the host vehicle.

17. The system of claim 15 , further comprising:
means for determining the preferred perspective location relative to a coordinate of a mapped object identified in a digital map.

18. The system of claim 15 , further comprising:
means for determining the preferred perspective location in accordance with a contour of a roadway traveled by the host vehicle.

19. The system of claim 15 , wherein the perception data comprises control points characteristic of a travel lane proximate to the host vehicle.

20. The system of claim 15 , wherein the means for transmitting the path request to move the perception sensor to the preferred perspective location comprise:
means for transmitting the path request to change a planned path of the assisting vehicle to move the perception sensor to the preferred perspective location.
