Abstract

A system and method for monitoring the location of each of a plurality of tires that are selectively and rotatably attached to a vehicle. A plurality of monitors are placed on the vehicle either within the air compartment of tire or proximate to the tire, monitoring either the air pressure or rotation of one of the plurality of tires, and transmitting the monitoring data to a receiving module in the vehicle. The receiving module determines if a tire attachment location-changing event has occurred on the vehicle based upon a change in tire pressure or a predetermined sequence of tire rotation, and preferably requests input of new tire locations on the vehicle.

Claims

1. A system for monitoring the location of each of a plurality of inflatable tires having an interior air compartment containing air therein under pressure, and each tire selectively rotatably attached to a vehicle, the system comprising:

a plurality of monitors, each monitor monitoring the air pressure in the air compartment of one of the plurality of tires, and each monitor transmitting data relative to a pressure change within the air compartment; and

a receiving module that receives the data from the plurality of monitors and determines if a tire location changing event has occurred on the vehicle based on the pressure change to establish the location of each of the plurality of tires.

2. The system of claim 1, wherein the receiving module, upon determining that a tire location changing event has occurred, requests input of the change of tire locations on the vehicle of each of the plurality of tires.

3. The system of claim 1, wherein the plurality of monitors are in wireless communication with the receiving module.

4. The system of claim 1, wherein the plurality of monitors are in wired communication with the receiving module.

5. The system of claim 1, wherein each of the plurality of monitors is located within a respective inflatable tire.

6. The system of claim 1, wherein each of the plurality of monitors is located proximate to a respective inflatable tire.

7. A system for monitoring the location of each of a plurality of inflatable tires having an interior air compartment containing air therein under pressure, and each tire selectively rotatably attached to a vehicle, the system comprising:

a plurality of monitors, each monitor monitoring the rotation of one of the plurality of tires, and each monitor transmitting data relative to tire rotation; and

a receiving module that receives the data from the plurality of monitors and determines if a tire location changing event has occurred on the vehicle based upon a predetermined sequence of tire rotation to establish the location of each of the plurality of tires.

8. The system of claim 7, wherein the receiving module determine if a tire location changing event has occurred based upon the individual rotation of one of the plurality of tires on the vehicle.

9. The system of claim 7, wherein the receiving module, upon determining that a tire location changing event has occurred, requests input of the change of tire locations on the vehicle of each of the plurality of tires.

10. The system of claim 7, wherein the plurality of monitors are in wireless communication with the receiving module.

11. The system of claim 7, wherein the plurality of monitors are in wired communication with the receiving module.

12. The system of claim 7, wherein each of the plurality of monitors is located within a respective inflatable tire.

13. The system of claim 7, wherein each of the plurality of monitors is located proximate to a respective inflatable tire.

14. A method for monitoring the location of each of a plurality of tires, and each tire selectively rotatably attached to a vehicle, the method comprising the steps of:

placing a plurality of monitors on the vehicle, each monitor proximate to one of the plurality of tires;

monitoring at each monitor the rotation of one of the plurality of tires;

transmitting data relative to the rotation of each of the plurality of tires to a receiving module in the vehicle; and

determining at the receiving module if a tire location changing event has occurred on the vehicle based upon a predetermined sequence of tire rotation to establish the location of each of the plurality of tires.

15. The method of claim 14, wherein the step of determining at the receiving module if a tire location changing event has occurred is determining if a tire location changing event has occurred based upon the individual rotation of one of the plurality of tires on the vehicle.

16. The method of claim 14, further comprising the step of requesting, at the receiving module, after a determination that a tire location changing event has occurred, the input of the change of tire locations on the vehicle of each of the plurality of tires.

17. The method of claim 14, wherein the step of transmitting data relative to the rotation of each of the plurality of tires is transmitting the data from plurality of monitors to the receiving module through wireless communication.

18. The method of claim 14, wherein the step of transmitting data relative to the rotation of each of the plurality of tires is transmitting the data from plurality of monitors to the receiving module through wired communication.
