Abstract

A self training tire pressure monitoring system for a vehicle includes at least two pressure sensors, at least two wheel sensors and a control. The pressure sensors are positioned at respective tires and are operable to provide a measured pressure output indicative of the pressure of the respective tires. The wheel sensors are positioned at respective wheels of the vehicle and are operable to provide a characteristic output indicative of rotation of the wheels over a period of time. The control receives the characteristic outputs and the measured pressure outputs and is operable to integrate the outputs to determine the particular wheels at which the pressure sensors and associated tires are positioned. The measured pressure and location of the tires may be displayed at a display of the vehicle. Preferably, the control deduces a deduced rolling radius of the tires in response to the characteristic output of the wheel sensors.
