Abstract

A system and method for detecting a missing vehicle tire and notifying a user of the vehicle about a potential vehicle tire theft. The method carried out by the system involves detecting that a tire is missing from a vehicle using a vehicle tire pressure monitoring (TPM) system and thereafter providing a notification of the missing tire via a wireless communication sent from a telematics unit on the vehicle. The wireless communication can be sent automatically by the telematics unit in response to the detection. Identification numbers or other data reported by sensors used in the TPM system can be used to determine if a tire is missing.

Claims

1. A method for detecting and responding to a potential tire theft, comprising the steps of:

(a) receiving an identification number corresponding to a sensor unit associated with a vehicle tire and comparing the received identification number to one or more stored identification numbers corresponding to one or more known sensor units associated with one or more tires of a particular vehicle;

(b) detecting that the received identification number does not correspond to a known sensor unit of the vehicle and that a tire is missing from the vehicle when the received identification number does not match at least one of the one or more stored identification numbers to which it was compared;

wherein the received identification number corresponds to a sensor unit not associated with the particular vehicle; and

(c) providing a notification of the missing tire via a wireless communication sent from a telematics unit on the vehicle, wherein wireless communication is sent automatically by the telematics unit in response to the detection.

2. The method of claim 1, further comprising, in response to step (b), the step of performing an audible and/or visual alert at the vehicle.

3. The method of claim 1, wherein the sensor unit comprises a tire pressure sensor attached to the tire, and step (a) further comprises receiving the identification number corresponding to the tire pressure sensor.

4. The method of claim 1, further comprising the step of determining that the vehicle is not being driven and carrying out steps (a) and (b) in response to the determination.

5. The method of claim 1, wherein step (c) further comprises notifying a call center about the missing tire via the wireless communication.

6. The method of claim 5, further comprising the step of reporting the missing tire to an owner of the vehicle or other interested party in response to the communication received by the call center.

7. The method of claim 1, wherein step (c) further comprises notifying an owner of the vehicle or other interested party via the wireless communication from the telematics unit.

8. The method of claim 1, further comprising the step of obtaining the vehicle'"'"'s location from the vehicle and reporting the missing tire and vehicle location to a police authority.

9. A method for detecting and responding to a potential tire theft, comprising the steps of:

(a) providing a vehicle having a TPM system that includes a TPM sensor attached to each of a number of the vehicle'"'"'s tires, each TPM sensor having a respective identification number corresponding thereto;

(b) determining an operational status of the vehicle;

(c) in response to the determined operational status, receiving a plurality of identification numbers, comparing each received identification number to one or more stored identification numbers corresponding to the TPM sensors of the vehicle, and detecting that at least one of the received identification numbers does not correspond to any of the TPM sensors of the vehicle and that at least one of the vehicle'"'"'s tires is missing based on a failure of at least one of the received identification numbers to match at least one of the stored identification numbers;

wherein the at least one of the received identification number corresponds to a TPM sensor not associated with the vehicle; and

(d) sending a notification of the one or more missing tires.

10. The method of claim 9, wherein step (b) further comprises determining the vehicle speed and wherein steps (c) and (d) are carried out if the speed is zero.

11. The method of claim 9, wherein step (c) is carried out by the TPM system.

12. The method of claim 9, wherein step (c) is carried out by a vehicle system module that obtains TPM sensor information from the TPM system.

13. The method of claim 9, wherein step (d) further comprises automatically sending a notification from a telematics unit of the vehicle in response to the detection of the one or more missing tires.

14. The method of claim 9, wherein step (d) further comprises the steps of:

sending a signal to a vehicle alert system which triggers a request to send a potential tire theft notification via a vehicle telematics unit; and

sending the notification from the vehicle telematics unit to a vehicle owner or other interested party in response to the request.

15. The method of claim 9, wherein step (d) further comprises the steps of:

sending a signal to a vehicle alert system which triggers a request to send a potential tire theft notification via a vehicle telematics unit; and

sending the notification from the vehicle telematics unit to a call center; and

then reporting the potential tire theft to a vehicle owner or other interested party via a communication from the call center.

16. The method of claim 9, further comprising, in response to step (c), the step of performing an audible and/or visual alert at the vehicle.
