Abstract

A system includes a processor and a memory. The memory stores instructions executable by the processor to, based on a vehicle destination, identify a diagnostic condition and a specified operating pattern of a vehicle component that includes at least one of vehicle propulsion, braking, and steering. The memory stores instructions executable by the processor to operate the vehicle based on the vehicle component and the operating pattern.

Claims

1. A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:

based on a vehicle destination, identify a diagnostic condition and a specified operating pattern of a vehicle component that includes at least one of vehicle propulsion, braking, and steering; and

operate the vehicle based on the vehicle component and the operating pattern.

2. The system of claim 1, wherein the operating pattern includes a maximum acceleration and a minimum acceleration.

3. The system of claim 2, wherein the instructions further include instructions to operate the vehicle at an acceleration greater than the minimum acceleration and less than the maximum acceleration.

4. The system of claim 1, wherein the operating pattern includes a maximum yaw rate and a minimum yaw rate.

5. The system of claim 1, wherein the operating pattern includes a maximum speed and a minimum speed associated with a road type.

6. The system of claim 1, wherein the instructions further include instructions to determine a vehicle route based on the destination and the vehicle diagnostic condition.

7. The system of claim 1, wherein the instructions further include instructions to select the vehicle diagnostic condition from a plurality of possible vehicle diagnostic conditions based on an assigned priority of each of the possible diagnostic conditions.

8. The system of claim 1, wherein the instructions further include instructions to identify the vehicle diagnostic condition from a plurality of possible vehicle diagnostic conditions based on at least one of terrain data, vehicle occupancy data, and traffic data, in addition to the vehicle destination.

9. The system of claim 1, wherein the vehicle diagnostic condition includes one or more of a substantially constant vehicle engine speed for a predetermined time, a deceleration caused by a fuel shut off, exceeding a predetermined vehicle speed, and applying a predetermined brake pressure.

10. The system of claim 1, wherein the instructions include further instructions to perform a diagnostic operation upon meeting the diagnostic condition, wherein the diagnostic operation includes verifying whether a fault condition was met.

11. The system of claim 1, wherein the instructions include further instructions to adjust the specified operating pattern upon determining that the vehicle is operating without a vehicle occupant.

12. A method, comprising:

based on a vehicle destination, identifying a diagnostic condition and a specified operating pattern of a vehicle component that includes at least one of vehicle propulsion, braking, and steering; and

operating the vehicle based on the vehicle component and the operating pattern.

13. The method of claim 12, wherein the operating pattern includes a maximum acceleration and a minimum acceleration.

14. The method of claim 13, further comprising operating the vehicle at an acceleration greater than the minimum acceleration and less than the maximum acceleration.

15. The method of claim 12, further comprising determining a vehicle route based on the destination and the vehicle diagnostic condition.

16. The method of claim 12, further comprising selecting the vehicle diagnostic condition from a plurality of possible vehicle diagnostic conditions based on an assigned priority of each of the possible diagnostic conditions.

17. The method of claim 12, further comprising identifying the vehicle diagnostic condition from a plurality of possible vehicle diagnostic conditions based on at least one of terrain data, vehicle occupancy data, and traffic data, in addition to the vehicle destination, wherein the vehicle diagnostic condition includes one or more of a substantially constant vehicle engine speed for a predetermined time, a deceleration caused by a fuel shut off, exceeding a predetermined vehicle speed, and applying a predetermined brake pressure.

18. A system, comprising:

a vehicle component that is one of vehicle propulsion, braking, and steering;

means for identifying, based on a vehicle destination, a diagnostic condition and a specified operating pattern of the vehicle component; and

means for operating the vehicle based on the identified diagnostic condition and the identified operating pattern.

19. The system of claim 18, wherein the identified diagnostic condition is based on at least one of terrain data, vehicle occupancy data, and traffic data, in addition to the vehicle destination.

20. The system of claim 18, further comprising means for operating the vehicle at an acceleration greater than a minimum acceleration and less than a maximum acceleration, wherein the operating pattern includes a maximum acceleration and a minimum acceleration.
