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

We claim:

1. A system for gathering perception-data, said system comprising:
a transceiver for installation on a host-vehicle, said transceiver configured to receive perception-data from a perception-sensor installed on an assisting-vehicle proximate to the host-vehicle; and
a controller-circuit in communication with the transceiver, said controller-circuit 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 configures the assisting-vehicle to steer, accelerate, or decelerate to change a planned-path of the assisting-vehicle to move the perception-sensor of the assisting-vehicle to the preferred-perspective.

2. The system in accordance with claim 1 , wherein the system includes an object-detector for installation on the host-vehicle, and the controller-circuit is configured to determine the preferred-perspective in accordance with a location of an obstructing-object detected by the object-detector.

3. The system in accordance with claim 1 , wherein the system includes a digital-map, and the controller-circuit is configured to determine the preferred-perspective in accordance with a coordinate of a mapped-object identified in the digital-map.

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

5. The system in accordance with claim 1 , wherein the perception-data includes control-points characteristic of a travel-lane proximate to the host-vehicle.

6. A controller-circuit for a system for gathering vehicle perception-data, said controller-circuit comprising:
a transceiver for installation on a host-vehicle, said transceiver configured to receive perception-data from a perception-sensor installed on an assisting-vehicle proximate to the host-vehicle; and
a processor in communication with the transceiver, said processor 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 configures the assisting-vehicle to steer, accelerate, or decelerate to change a planned-path of the assisting-vehicle to move the perception-sensor of the assisting-vehicle to the preferred-perspective.

7. The controller-circuit in accordance with claim 6 , wherein the processor is configured to receive object-data from an object-detector of the host-vehicle, and the controller-circuit is configured to determine the preferred-perspective in accordance with a location of an obstructing-object detected by the object-detector.

8. The controller-circuit in accordance with claim 6 , wherein the processor is configured to communicate with a digital-map, and determine the preferred-perspective in accordance with a coordinate of a mapped-object identified in the digital-map.

9. The controller-circuit in accordance with claim 6 , wherein the processor is configured to determine a contour of a roadway traveled by the host-vehicle, and determine the preferred-perspective for the perception-sensor of the assisting-vehicle in accordance with the contour.

10. The controller-circuit in accordance with claim 6 , wherein the perception-data includes control-points characteristic of a travel-lane proximate to the host-vehicle.

11. A method of operating a system for gathering vehicle perception-data, said method comprising:
receiving, by a transceiver for installation on a host-vehicle, perception-data from a perception-sensor installed on an assisting-vehicle proximate to the host-vehicle;
determining, by a controller-circuit in communication with the transceiver, a preferred-perspective for gathering perception-data by the perception-sensor of the assisting-vehicle; and
transmitting, by the transceiver, a path-request to the assisting-vehicle that configures the assisting-vehicle to steer, accelerate, or decelerate to change a planned-path of the assisting-vehicle to move the perception-sensor of the assisting-vehicle to the preferred-perspective.

12. The method in accordance with claim 11 , wherein the method includes:
receiving object-data from an object-detector; and
determining the preferred-perspective in accordance with a location of an obstructing-object detected by the object-detector.

13. The method in accordance with claim 11 , wherein the method includes:
accessing a digital-map that indicates a coordinate of a mapped-object; and
determining the preferred-perspective in accordance with the coordinate of the mapped-object.

14. The method in accordance with claim 11 , wherein the method includes:
determining a contour of a roadway traveled by the host-vehicle; and
determining the preferred-perspective for the perception-sensor of the assisting-vehicle in accordance with the contour.

15. The method in accordance with claim 11 , wherein the method includes:
determining, by the assisting-vehicle, control-points characteristic of a travel-lane proximate to the host-vehicle.

16. The method in accordance with claim 11 , wherein transmitting the path-request configures the assisting-vehicle to accelerate to improve quality of the perception-data collected by the perception-sensor on the assisting-vehicle.

17. The method in accordance with claim 11 , wherein transmitting the path-request configures the assisting-vehicle to slow-down to improve quality of the perception-data collected by the perception-sensor on the assisting-vehicle.

18. The method in accordance with claim 11 , wherein transmitting the path-request configures the assisting-vehicle to steer from one traffic lane to another traffic lane to improve quality of the perception-data collected by the perception-sensor on the assisting-vehicle.

19. The method in accordance with claim 11 , wherein transmitting the path-request includes transmitting a specific request from a group including a lane-change, a speed-change, a position-change within a present lane, and a position-maintain between the host-vehicle and the assisting-vehicle until the host-vehicle determines that an obstructing-vehicle is out of the way of the preferred-perspective.

20. The method in accordance with claim 11 , wherein transmitting the path-request includes transmitting a speed-change that configures the assisting-vehicle to reach the preferred-perspective as quickly as possible when the host-vehicle passes an obstructing-vehicle in the way of the preferred-perspective.
