Abstract

Approaches for top speed dependent operational parameter configuration are disclosed. An operational parameter to be used by an autonomous vehicle is received. Operational modes and corresponding operational regions are determined based on the received operational parameter. A first set of autonomous vehicle parameters are determined and set based on the received operational parameter. A second set of autonomous vehicle parameters are determined and set based on the first set of autonomous vehicle parameters.

First claim

What is claimed is:

1. An autonomous vehicle comprising:
sensor systems to detect characteristics of an operating environment;
a vehicle control system coupled with the sensor systems, the vehicle control system to:
receive an operational parameter to be used by an autonomous vehicle;
determine operational modes and corresponding operational regions based on the received operational parameter;
set a first set of autonomous vehicle parameters based on the received operational parameter;
set a second set of autonomous vehicle parameters based on the first set of autonomous vehicle parameters,
wherein the vehicle control system is further configured to select an appropriate maximum allowable top speed from a table of maximum allowable top speeds having corresponding parameters based on a correspondence of operating conditions with the parameters.

2. The autonomous vehicle of claim 1 wherein the operational parameter comprises a maximum allowable top speed for the autonomous vehicle.

3. The autonomous vehicle of claim 1 wherein the operational regions correspond to an operational design domain (ODD) having speed limits within a maximum allowable top speed for the autonomous vehicle and the operational modes correspond to autonomous operation and non-autonomous driving.

4. The autonomous vehicle of claim 3 wherein autonomous driving corresponds to full autonomous driving by the autonomous vehicle and non-autonomous driving corresponds to use of human-provided input for operation of the autonomous vehicle.

5. The autonomous vehicle of claim 1 wherein the operational parameter is received via an interface of the autonomous vehicle.

6. The autonomous vehicle of claim 1 wherein the operational parameter is received via a network connection from a remote operations center.

7. A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, are configurable to cause the processors to: receive an operational parameter to be used by an autonomous vehicle; determine operational modes and corresponding operational regions based on the received operational para meter; set a first set of autonomous vehicle parameters based on the received operational parameter; set a second set of autonomous vehicle parameters based on the first set of autonomous vehicle parameters, wherein the one or more processor are further configured to select an appropriate maximum allowable top speed from a table of maximum allowable top speeds having corresponding parameters based on a correspondence of operating conditions with the parameters.

8. The non-transitory computer-readable medium of claim 7 wherein the operational parameter comprises a maximum allowable top speed for the autonomous vehicle.

9. The non-transitory computer-readable medium of claim 7 wherein the operational regions correspond to an operational design domain (ODD) having speed limits within a maximum allowable top speed for the autonomous vehicle and the operational modes correspond to autonomous operation and non-autonomous driving.

10. The non-transitory computer-readable medium of claim 9 wherein autonomous driving corresponds to full autonomous driving by the autonomous vehicle and non-autonomous driving corresponds to use of human-provided input for operation of the autonomous vehicle.

11. The non-transitory computer-readable medium of claim 7 wherein the operational parameter is received via an interface of the autonomous vehicle.

12. The non-transitory computer-readable medium of claim 7 wherein the operational parameter is received via a network connection from a remote operations center.

13. A system comprising: a memory system; and one or more hardware processors coupled with the memory system, the one or more processors to:
receive an operational parameter to be used by an autonomous vehicle;
determine operational modes and corresponding operational regions based on the received operational parameter;
set a first set of autonomous vehicle parameters based on the received operational parameter;
set a second set of autonomous vehicle parameters based on the first set of autonomous vehicle parameters,
wherein the one or more hardware processors are further configured to select an appropriate maximum allowable top speed from a table of maximum allowable top speeds having corresponding parameters based on a correspondence of operating conditions with the parameters.

14. The system of claim 13 wherein the operational parameter comprises a maximum allowable top speed for the autonomous vehicle.

15. The system of claim 13 wherein the operational regions correspond to an operational design domain (ODD) having speed limits within a maximum allowable top speed for the autonomous vehicle and the operational modes correspond to autonomous operation and non-autonomous driving.

16. The system of claim 15 wherein autonomous driving corresponds to full autonomous driving by the autonomous vehicle and non-autonomous driving corresponds to use of human-provided input for operation of the autonomous vehicle.

17. The system of claim 13 wherein the operational parameter is received via an interface of the autonomous vehicle.

18. The system of claim 13 wherein the operational parameter is received via a network connection from a remote operations center.
