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.

First claim

What is claimed is:

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.
