METHOD AND APPARATUS FOR IDENTIFYING REMOTE SENDING UNITS INA VEHICLE

摘要

A remote tire pressure monitoring system includes a sending unit for each monitored tire, and the sending units transmit RF signals, each including an identifier ID(i) and a pressure indicator P(i). A receiver operates in a learn mode in which the receiver associates specific identifiers either with the vehicle or with specific tires. During the learn mode the vehicle i s driven at a speed above a threshold speed, such as thirty miles an hour, and identifiers are associated with either the vehicle or the respective tires o f the vehicle only if they persist for a selected number of signals or frames duri ng the learning period. In one example, the tires are inflated with different pressures according to a predetermined pattern, and the pressure indicators of the receive signals are used to associate individual tire positions with the respective sending units.
