System and method for sensing an operating parameter of a vehicle tire
First Claim
1. A system for monitoring an operating parameter of a vehicle tire, the tire being mountable on a rim that is mountable on a rotatable wheel hub of the vehicle, said system comprising:
- an identification connected to the rim, said identification conveying a rim identification code;
means for sensing an operating parameter of the tire, said means for sensing providing a radio frequency signal indicative of a sensed operating parameter of the tire and an identification code of said means for sensing;
means for detecting said identification and providing a rim identification signal, said rim identification signal being indicative of said rim identification code and the position on the vehicle where the tire is mounted;
means for receiving said radio frequency signal;
means for receiving said rim identification signal; and
means for correlating said radio frequency signal with said rim identification signal to associate said radio frequency signal with the position on the vehicle where the tire is mounted.

Abstract
A system (10) for monitoring an operating parameter of a tire (12) on a vehicle (14) includes an identification (72) connected to a vehicle rim (50) that conveys a rim identification code. A tire-based unit (20) senses an operating parameter of the tire (12) and provides a radio frequency signal (24) indicative of a sensed operating parameter of the tire and an identification code of the tire-based unit. A rim identification sensor (30) detects the identification (72) and provides a rim identification signal (32) indicative of the rim identification code and the position of the rim (50) on the vehicle (14). The system also includes electronics (40) for receiving the radio frequency signal (24) and the rim identification signal (32). The electronics (40) correlate the radio frequency signal (24) with the rim identification signal (32) to associate the radio frequency signal with the position on the vehicle (14) where the tire (12) is mounted.
