Policy managed vehicle operation systems and methods
This disclosure relates to, among other things, managing the operation of a vehicle in accordance with one or more policies. Consistent with various aspects of the disclosed embodiments, a vehicle control system may be used to enforce policy in connection with various vehicle operations based, at least in part, on trusted information provided by one or more vehicle subsystems and/or other systems. A vehicle control system may verify the received information and use the verified information to determine whether the vehicle may engage in a particular operation and/or enter a particular operational mode in accordance with one or more policies.
1. A method for managing at least one controlled operation of a vehicle performed by a vehicle control system comprising a processor and a non-transitory computer readable storage medium storing instructions that, when executed by the processor, cause the vehicle control system to perform the method, the method comprising:
receiving a control request for the vehicle to engage in the at least one controlled operation;
identifying, based at least in part on the control request, at least one vehicle operation management policy stored by the vehicle control system, the at least one vehicle management policy identifying one or more vehicle subsystems included in the vehicle associated with the at least one controlled operation and specifying one or more conditions associated with the at least one controlled operation;
receiving subsystem information and at least one first trusted certificate from at least one of the one or more vehicle subsystems, the at least one first trusted certificate comprising information relating to at least one characteristic of an associated subsystem;
determining, based at least in part on the subsystem information and the at least one first trusted certificate, whether the one or more conditions specified in the vehicle operation management policy have been satisfied;
generating, in accordance with the determination, a control action signal; and
transmitting the control action signal to at least one vehicle system associated with the at least one controlled operation.
2. The method of claim 1 , wherein the at least one controlled operation comprises at least one of an autonomous operation, a semi-autonomous operation, and a driver-assist operation.
3. The method of claim 1 , wherein the method further comprises receiving the at least one vehicle operation management policy from a policy service in communication with the vehicle control system.
4. The method of claim 1 , wherein the one or more vehicle subsystems comprise at least one sensor system.
5. The method of claim 4 , wherein the subsystem information comprises sensor information generated by the at least one sensor system.
6. The method of claim 1 , wherein the information relating to the at least one characteristic of the associated subsystem comprises at least one of subsystem identification information, subsystem manufacturer information, subsystem model information, subsystem serial number information, and subsystem software version information.
7. The method of claim 6 , wherein the one or more conditions specified in the vehicle operation management policy comprise at least one condition relating to at least one characteristic of the associated subsystem.
8. The method of claim 7 , wherein the one or more conditions further specify at least one threshold associated with the received subsystem information.
9. The method of claim 8 , wherein determining whether the one or more conditions have been satisfied comprises comparing the received subsystem information with the at least one threshold.
10. The method of claim 1 , wherein the method further comprises verifying authenticity of the at least one first trusted certificate with a trusted service provider system.
11. The method of claim 1 , wherein the method further comprises receiving at least one cryptographic signature associated with the received subsystem information.
12. The method of claim 11 , wherein the method further comprises verifying that the at least one cryptographic signature was generated using a private key securely associated with the at least one subsystem.
13. The method of claim 1 , wherein the method further comprises receiving at least one second trusted certificate from a device associated with a driver of the vehicle.
14. The method of claim 13 , wherein the at least one second trusted certificate comprises an indication of an authority of the driver to engage in the at least one controlled operation.
15. The method of claim 13 , wherein determining whether the one or more conditions specified in the vehicle operation management policy have been satisfied is further based, at least in part, on the at least one second trusted certificate.
