Abstract

A pressure of a spare tire of a vehicle is determined. Whether the spare tire is installed is determined based at least in part on the pressure. A vehicle subsystem is actuated based at least in part on whether the spare tire is installed.

Claims

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

determine a pressure of a spare tire of a vehicle;

determine whether the spare tire is installed based at least in part on the pressure; and

actuate a vehicle subsystem based at least in part on whether the spare tire is installed.

2. The system of claim 1, wherein the instructions further include instructions to determine a first pressure reading of the spare tire upon initial activation of the vehicle.

3. The system of claim 2, wherein the instructions further include instructions to determine a second pressure reading of the spare tire at a predetermined period of time after initial activation of the vehicle and to actuate the vehicle subsystem if the second pressure reading is greater than the first pressure reading.

4. The system of claim 1, wherein the vehicle subsystem is at least one of a propulsion, a brake, a steering, a speed limiter, and a navigation subsystem.

5. The system of claim 4, wherein the instructions further include instructions to actuate the speed limiter to limit a vehicle speed to a speed threshold when the determined pressure of the spare tire is below a pressure threshold.

6. The system of claim 1, wherein the instructions further include instructions to identify a repair destination when the pressure is below a pressure threshold and to actuate the vehicle propulsion and the steering to move the vehicle to the repair destination.

7. The, system of claim 6, wherein the instructions further include instructions to determine operating parameters based at least in part on the pressure of the spare tire and to send a notification to the repair destination with the operating parameters.

8. The system of claim 1, wherein the instructions further include instructions to determine whether the tire is present and to actuate the vehicle subsystem upon determining that the spare tire is not present.

9. The system of claim 8, wherein the instructions further include instructions to determine whether the spare tire is present in a spare tire housing and to actuate the vehicle subsystem upon determining that the spare tire is not present in the spare tire housing.

10. The system of claim 8, wherein the instructions further include instructions to detect a serial number of a pressure sensor installed in the spare tire to determine whether the spare tire is present.

11. A method, comprising:

determining a pressure of a spare tire of a vehicle;

determining whether the spare tire is installed based at least in part on the pressure; and

actuating a vehicle subsystem based at least in part on whether the spare tire is installed.

12. The method of claim 11, further comprising determining a first pressure reading of the spare tire upon initial activation of the vehicle.

13. The method of claim 12, further comprising determining a second pressure reading of the spare tire at a predetermined period of time after initial activation of the vehicle and actuating the vehicle subsystem if the second pressure reading is greater than the first pressure reading.

14. The method of claim 11, wherein the vehicle subsystem is at least one of a propulsion., a brake, a steering, a speed limiter, and a navigation subsystem.

15. The method of claim 14, further comprising actuating the speed limiter limit a vehicle speed to a speed threshold when the determined pressure of the spare tire is below a pressure threshold.

16. The method of claim 11, further comprising identifying a repair destination when the pressure is below a pressure threshold and actuating the vehicle propulsion and the steering to move the vehicle to the repair destination.

17. The method of claim 16, further comprising determining operating parameters based at least in part on the pressure of the spare tire and to send a notification to the repair destination with the operating parameters.

18. The method of claim 11, further comprising determining whether the tire is present and to actuate the vehicle subsystem upon determining that the spare tire is not present.

19. The method of claim 18, wherein the instructions further include instructions to determine whether the spare tire is present in a spare tire housing and to actuate the vehicle subsystem upon determining that the spare tire is not present in the spare tire housing.

20. The method of claim 18, further comprising detecting a serial number of a pressure sensor installed in the spare tire to determine whether the spare tire is present.
