Abstract

Method for allocating identification codes which are contained in signals transmitted by components of a tire pressure monitoring system, said components being attached to wheels of the vehicle, to the wheel positions. A plurality of sensors to the tire pressure, to the rolling direction of the wheel, to the shocks, as well as a memory for the identification code, and a transmitter which supplies signals with the identification code, the rolling direction and the occurrence of a shock on a wheel to a receiver which, based on the supplied rolling direction information, distinguishes identification codes pertaining to wheels on the left-hand or right-hand side of the vehicle from shocks which occur on the left-hand or right-hand side of the vehicle, measures the time interval elapsing between shock signals on one side of the vehicle, multiplies this time interval by the velocity of the vehicle measured within the same time interval.
