Method and system of notifying of overuse of a mini-spare tire in a tire pressure monitoring system for an automotive vehicle

摘要

A tire pressure monitoring system (12) for a vehicle (10) has a mini-spare tire 14e having a spare tire transmitter (16e) generating a mini-spare transmitter identification signal, a distance sensor generating a distance signal and a controller (22) coupled to the mini-spare tire. The controller (22) starts the timer in response to receiving the spare tire identification signal. The controller (22) determines a mini-spare distance signal and generates a warning signal when the mini-spare distance signal exceeds a predetermined distance.
