Abstract:
1. A method carried out in a wheel unit of a tire pressure monitoring system, comprising: detecting, based at least in part on parameters sensed at the wheel unit, increases and decreases in loading of a tire on a wheel associated with the wheel unit during acceleration and deceleration; determining, based at least in part on parameters sensed at the wheel unit, front/rear position of said wheel unit on a vehicle mounting said tire pressure monitoring system based on said increases and decreases in loading of said tire and wheel during acceleration and deceleration; detecting rotation direction of said wheel generally at said wheel unit; determining, based at least in part on parameters sensed at the wheel unit, left/right position of said wheel unit on said vehicle based at least in part on said rotation direction of said wheel; and transmitting an indication of the front/rear and left/right position of the wheel on the vehicle and an identification unique to the transmitting wheel unit.
