Abstract

A system includes a computer including a processor and a memory, the memory including instructions executable by the processor to identify a degraded state of a vehicle component when a component usage exceeds a first threshold and a weather datum exceeds a second threshold, and then actuate the vehicle component in response to the degraded state.

Claims

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

collect data of component usage of a vehicle component from a vehicle entering a storage area;

collect a weather datum with an infrastructure sensor located in the storage area in which the vehicle enters;

identify a degraded state of the vehicle component when the component usage exceeds a first threshold and the weather datum exceeds a second threshold; and

then actuate the vehicle component in response to the degraded state.

2. The system of claim 1, wherein the instructions further include instructions to identify a battery charge level of a battery and to actuate the battery to move the vehicle to a charging station in response to the degraded state when the battery charge level is below a battery charge threshold.

3. The system of claim 1, wherein the instructions further include instructions to identify a tire tread depth, to identify the degraded state based on the tire tread depth, and to actuate a propulsion in response to the degraded state when the tire tread depth is below a tread depth threshold.

4. The system of claim 1, wherein the instructions further include instructions to identify a fuel fill date, the fuel fill date indicating a most recent date that a fuel tank of a vehicle was filled, and to actuate a propulsion to consume fuel in response to the degraded state when the fuel fill date is older than a fill date threshold.

5. The system of claim 1, wherein the instructions further include instructions to identify a brake engagement date, the brake engagement date indicating a most recent date that a brake of the vehicle was actuated, to identify the degraded state when the brake engagement date is older than a brake engagement date threshold and to actuate the brake in response to the degraded state.

6. The system of claim 1, wherein the instructions further include instructions to determine a pavement temperature and to identify the degraded state for a tire when the pavement temperature is below a pavement temperature threshold and an elapsed parked time for the vehicle exceeds a parked time threshold.

7. The system of claim 1, wherein the weather datum includes an ambient temperature, the instructions further include instructions to identify the degraded state based on the ambient temperature.

8. The system of claim 7, wherein the instructions further include instructions to identify a battery charge level of a battery in the vehicle and to actuate the battery in response to the degraded state when the ambient temperature is below a first temperature threshold and above a second temperature threshold and when the battery charge level is below a battery charge threshold.

9. The system of claim 1, wherein the instructions to actuate the vehicle component further include instructions to actuate a propulsion to move the vehicle along a predetermined route for a predetermined period of time.

10. The system of claim 1, wherein the component usage includes data about operation of a plurality of vehicle components from a most recent route performed by the vehicle, the route being a route followed by the vehicle from a start point to an end point.

11. The system of claim 10, wherein the instructions further include instructions to assign a new route to the vehicle upon determining that the degraded state is resolved.

12. The system of claim 1, wherein the instructions further include instructions to collect component usage data from a plurality of vehicles, to identify one or more vehicles having a respective degraded state for at least one respective vehicle component, and to assign a route at least one of the vehicles lacking a degraded state.

13. A method, comprising:

collecting data of component usage of a vehicle component from a vehicle entering a storage area;

collecting a weather datum with an infrastructure sensor located in the storage area in which the vehicle enters;

identifying a degraded state of the vehicle component when the component usage exceeds a first threshold and the weather datum exceeds a second threshold; and

then actuating the vehicle component in response to the degraded state.

14. The method of claim 13, further comprising actuating a propulsion to move the vehicle along a predetermined route for a predetermined period of time.

15. The method of claim 13, wherein the component usage includes data about operation of a plurality of vehicle components from a most recent route performed by the vehicle, the route being a route followed by the vehicle from a start point to a destination.

16. The method of claim 13, further comprising collecting component usage data from a plurality of vehicles, identifying one or more vehicles having a respective degraded state for at least one respective vehicle component, and assigning a route at least one of the vehicles lacking a degraded state.

17. A system, comprising:

means for collecting data of component usage of a vehicle component from a vehicle entering a storage area;

means for collecting a weather datum with an infrastructure sensor located in the storage area in which the vehicle enters;

means for identifying a degraded state of the vehicle component when the component usage exceeds a first threshold and the weather datum exceeds a second threshold; and

means for actuating the vehicle component in response to the degraded state.

18. The system of claim 17, further comprising means for actuating a propulsion to move the vehicle along a predetermined route for a predetermined period of time.

19. The system of claim 17, wherein the component usage includes data about operation of a plurality of vehicle components from a most recent route performed by the vehicle, the route being a route followed by the vehicle from a start point to a destination.

20. The system of claim 17, further comprising means for collecting component usage data from a plurality of vehicles, means for identifying one or more vehicles having a respective degraded state for at least one respective vehicle component, and means for assigning a route at least one of the vehicles lacking a degraded state.
