Adjustment of autonomous vehicle control authority
Apparatuses, methods, and systems adjust the level of control authority of one or more autonomous vehicles in order to respond to changes in one or more operating conditions associated with the vehicle, operator, environment, route, and other conditions.
1. A method comprising:
receiving at an electronic controller one or more operating conditions associated with at least one vehicle operable along a route via a prime mover;
determining with the electronic controller, in response to the one or more operating conditions, a vehicle control authority modification parameter for the at least one vehicle, wherein the operating conditions include telemetry data associated with a maneuver of the at least one vehicle and the vehicle control authority modification parameter is based at least in part on an assessment of the telemetry data for a maneuver of the at least one vehicle that determines a likelihood of violating an operating constraint by the at least one vehicle;
modifying a level of autonomous vehicle control in response to the vehicle control authority modification parameter, wherein the vehicle control authority modification parameter modifies one or more control decisions from autonomous control to operator control based on the assessment of the telemetry data determining the operating constraint will be violated by the maneuver under autonomous control; and
controlling operation of the at least one vehicle in response to the modified level of autonomous vehicle control.
2. The method of claim 1 , wherein the electronic controller is provided entirely in at least one electronic control unit of the at least one vehicle.
3. The method of claim 1 , wherein the electronic controller is provided entirely in at least one electronic control unit that is remote from the at least one vehicle.
4. The method of claim 1 , wherein the electronic controller is distributed among at least one electronic control unit that is in the at least one vehicle and an electronic control unit that is remote from the at least one vehicle.
5. The method of claim 1 , wherein the operating conditions include a quality of incoming vehicle data from one or more sensors associated with the at least one vehicle and the vehicle control authority modification parameter is based on an assessment of the quality of the incoming vehicle data.
6. The method of claim 1 , wherein the operating conditions include an available level of autonomous vehicle control provided by each of two or more sensors associated with the at least one vehicle and the vehicle control authority modification parameter is based on a determination of an available capability level of autonomous vehicle control provided by the two or more sensors.
7. The method of claim 1 , wherein the operating constraint for the at least one vehicle based is maintaining a travel lane for the at least one vehicle and the assessment of the telemetry data includes assessing the maneuver required by the at least one vehicle to make a turn while maintaining the travel lane.
8. The method of claim 1 , wherein the operating conditions include operator data associated with the operator of the at least one vehicle and the vehicle control authority modification parameter is based on an assessment of the operator data.
9. The method of claim 8 , wherein the operator data includes at least one of a responsiveness of the operator and an inappropriate/unsafe operator maneuver.
10. The method of claim 1 , wherein the operating conditions include geo-fencing data along the route of the at least one vehicle and the vehicle control authority modification parameter is based on an assessment of the geo-fencing data.
11. A vehicle electronic control system, comprising:
an electronic controller configured to:
receive one or more operating conditions associated with at least one vehicle operable along a route via a prime mover;
determine, in response to the one or more operating conditions, a vehicle control authority modification parameter for the at least one vehicle, wherein the vehicle control authority modification parameter is based at least in part on an assessment of telemetry data for a maneuver of the at least one vehicle that determines a likelihood of violation of an operating constraint for the at least one vehicle;
modify a level of autonomous vehicle control in response to the vehicle control authority modification parameter, wherein the vehicle control authority modification parameter modifies one or more control decisions from autonomous control to operator control based at least in part on the assessment of the telemetry data determining the operating constraint will be violated by the maneuver of the at least one vehicle under autonomous control; and
control operation of the at least one vehicle in response to the modified level of autonomous vehicle control.
12. The vehicle electronic control system of claim 11 , wherein the electronic controller includes a memory and a non-transitory computer readable medium including instructions encoded thereon.
13. The vehicle electronic control system of claim 11 , wherein the electronic controller is provided entirely in an electronic control unit of the at least one vehicle.
14. The vehicle electronic control system of claim 11 , wherein the electronic controller is distributed among an electronic control unit of the at least one vehicle and an electronic control unit that is remote from the at least one vehicle.
15. The vehicle electronic control system of claim 11 , wherein the electronic controller is provided entirely remotely from and is in communication with an electronic control unit of the at least one vehicle.
16. The vehicle electronic control system of claim 11 , wherein the operating conditions include one or more of:
a quality of incoming vehicle data from one or more sensors associated with the at least one vehicle;
an available level of autonomous vehicle control provided by each of two or more sensors associated with the at least one vehicle;
operator data associated with the operator of the at least one vehicle; and
geo-fencing data along a route of the at least one vehicle.
17. The vehicle electronic control system of claim 11 , wherein the vehicle control authority modification parameter is further based on one or more of:
an assessment of a quality of incoming vehicle data regarding the at least one vehicle;
a determination of an available capability level of autonomous vehicle control provided by two or more sensors on the at least one vehicle;
an assessment of a condition of the operator of the at least one vehicle; and
an assessment of geo-fencing data along the route of the at least one vehicle.
18. The vehicle electronic control system of claim 11 , wherein the modified level of autonomous vehicle control is a reduction in autonomous control capability of the at least one vehicle.
19. The vehicle electronic control system of claim 11 , wherein the operating constraint for the at least one vehicle is maintaining a travel lane for the at least one vehicle and the assessment of the telemetry data includes assessing the maneuver required by the at least one vehicle to make a turn while maintaining the travel lane.
20. The vehicle electronic control system of claim 11 , wherein the operating conditions including operator data associated with the operator of the vehicle and the vehicle control authority modification parameter includes initiating autonomous operation of the at least one vehicle in response to an unresponsive or unsafe operator behavior.
21. The vehicle electronic control system of claim 20 , wherein the autonomous operation includes bringing the at least one vehicle to a stop.
22. The vehicle electronic control system of claim 11 , wherein the operating conditions including geo-fencing data along a route of the at least one vehicle and the vehicle control authority modification parameter includes adjusting one or more safety parameters of the at least one vehicle in response to the geo-fencing data.
