Abstract
A method carried out in a wheel unit of a tire pressure monitoring system comprises detecting, using a controller in the wheel unit, increases and decreases in loading of a tire on a wheel associated with the wheel unit during acceleration and deceleration. Front/rear position of the wheel unit on a vehicle mounting the tire pressure monitoring system is determined, using the controller in the wheel unit, based on the loading and unloading of the tire and wheel during acceleration and deceleration. Rotation direction of the wheel in the wheel unit is determined and the controller in the wheel unit determines left/right position of the wheel unit on the vehicle based on the rotation direction of the wheel. 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 are transmitted.
