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.
