Abstract

A map-data collection system for mapping an area includes a first sensor, a receiver, and a controller-circuit. The first-sensor is for installation on a first-vehicle. The first-sensor is configured to gather perception-data of an area from a first-perspective. The receiver is for installation on the first-vehicle. The receiver is configured to receive perception-data gathered by a second-sensor mounted on a second-vehicle proximate to the first-vehicle. The second-sensor is configured to gather perception-data of the area from a second-perspective different from the first-perspective. The controller-circuit is in communication with the first-sensor and the receiver. The controller-circuit is configured to determine composite-data in accordance with the perception-data from the first-sensor on the first-vehicle and the perception-data from the second-sensor on the second-vehicle. Optionally, the first-vehicle may communicate with the second-vehicle in a manner effective to control the relative-position of the first-vehicle and the second-vehicle while the perception-date is being collected.

First claim

We claim:

1. A system comprising:
a sensor configured to collect perception data of an area of a roadway from a perspective of a vehicle;
a receiver configured to receive other perception data of the area from another sensor mounted on another vehicle, the other perception data of the area having been collected from another perspective of the other vehicle that is different than the perspective of the vehicle;
a controller operatively connected to the sensor and the receiver, the controller configured to:
determine, based on the perception data from the sensor and the other perception data from the other sensor, composite data that identifies one or more objects in the area; and
generate, based on the composite data, a control message including instructions to control a relative position of the other vehicle with respect to the vehicle to optimize at least one of the perception data from the sensor or the other perception data from the other sensor; and

a transmitter configured to transmit the control message to the other vehicle.

2. The system in accordance with claim 1 , wherein the perception data from the sensor and the other perception data from the other sensor used to determine the composite data are temporally synchronized.

3. The system in accordance with claim 1 , wherein the controller is further configured to determine the composite data in accordance with a relative position of the vehicle with respect to the other vehicle.

4. The system in accordance with claim 3 , wherein the relative position of the vehicle with respect to the other vehicle is determined in accordance with at least one of the perception data from the sensor, the other perception data from the other sensor, or position data from a third sensor.

5. The system in accordance with claim 1 , wherein the control message includes a desired distance and a desired direction.

6. The system in accordance with claim 1 , wherein the system includes an inertial measurement unit, and the control message includes inertial data from the inertial measurement unit that is used to control the other vehicle.

7. The system in accordance with claim 1 , wherein the system includes a digital map that indicates the one or more objects in the area, the control message includes a coordinate of the one or more objects in the area to control the relative position of the other vehicle with respect to the vehicle in accordance with the one or more objects in the area.

8. The system in accordance with claim 1 , wherein the controller is further configured to communicate with the transmitter to transmit a configuration message to the other vehicle, the configuration message including a configuration parameter to configure the other sensor.

9. The system of claim 1 , wherein the instructions of the control message include information to operate at least one of a steering, an accelerator, or brakes of the other vehicle.

10. A controller comprising:
an input configured to receive from a sensor perception data of an area of a roadway from a perspective of a vehicle;
a receiver configured to receive other perception data of the area from another sensor mounted on another vehicle, the other perception data of the area having been collected from another perspective of the other vehicle that is different than the perspective of the vehicle;
a processor operatively connected to the input and the receiver, the processor configured to:
determine, based on the perception data from the sensor and the other perception data from the other sensor, composite data that identifies one or more objects in the area; and
generate, based on the composite data, a control message including instructions to control a relative position of the other vehicle with respect to the vehicle to optimize at least one of the perception data from the sensor or the other perception data from the other sensor; and

a transmitter configured to transmit the control message to the other vehicle.

11. The controller in accordance with claim 10 , wherein the perception data from the sensor and the other perception data from the other sensor used to determine the composite data are temporally synchronized.

12. The controller in accordance with claim 10 , wherein the processor is further configured to determine the composite data in accordance with a relative position of the vehicle with respect to the other vehicle.

13. The controller in accordance with claim 12 , wherein the relative position of the vehicle with respect to the other vehicle is determined in accordance with at least perception data from the sensor, the other perception data from the other sensor, or position data from a third sensor.

14. The controller in accordance with claim 10 , wherein the control message includes a desired distance and a desired direction.

15. The controller in accordance with claim 10 , wherein the processor is further configured to communicate with an inertial measurement unit, and the control message includes inertial data from the inertial measurement unit that is used to control the other vehicle.

16. The controller in accordance with claim 10 , wherein the processor is further configured to access a digital map that indicates the one or more objects in the area, the control message includes a coordinate of the one or more objects in the area to control the relative position of the other vehicle with respect to the vehicle in accordance with the one or more objects in the area.

17. The controller in accordance with claim 10 , wherein the processor is further configured to communicate with the transmitter to transmit a configuration message to the other vehicle, the configuration message including a configuration parameter to configure the other sensor.

18. The controller of claim 10 , wherein the instructions of the control message include information to operate at least one of a steering, an accelerator, or brakes of the other vehicle.

19. A method comprising:
collecting, by a sensor of a vehicle, perception data of an area of a roadway from a perspective of the vehicle;
receiving, by a receiver from another sensor mounted on another vehicle, other perception data of the area, the other perception data of the area having been collected from another perspective of the other vehicle that is different than the perspective of the vehicle;
determining, by a controller operatively connected to the sensor and the receiver, composite data that identifies one or more objects in the area, the determining based on the perception data from the sensor and the other perception data from the other sensor;
generating, by the controller and based on the composite data, a control message including instructions to control a relative position of the other vehicle with respect to the vehicle to optimize at least one of the perception data from the sensor or the other perception data from the other sensor; and
transmitting, by a transmitter, the control message to the other vehicle.

20. The method in accordance with claim 19 , wherein the method further comprises:
synchronizing temporally the perception data from the sensor with the other perception data from the other sensor that is used to determine the composite data.

21. The method in accordance with claim 19 , wherein the method further comprises:
