Abstract

A method for allocating identifiers, that are contained in signals issued by transmitters arranged in a tire pressure monitoring system, to the positions of the wheels by transmitting the signals to a receiving and analysis circuit, which analyses the information, contained in the signal, whereinfor differentiating between wheels on the right side of the vehicle and wheels on the left side of the vehicle, the sign of a translation acceleration b is determined for each running wheel,the sign of the variation of the centrifugal acceleration z occurring during the translation acceleration b is additionally determined and multiplied by the sign of the translation acceleration b determined for the respective wheel, and the differentiation between wheels on the right side of the vehicle and wheels on the left side of the vehicle is effected by comparing the products of the two signs determined for the wheels.
