Abstract

A method for assigning identifiers of wheel electronics to the positions of the wheels on the vehicle is disclosed. The wheel electronics send their individual identifier with information relating to the rotational direction of the wheel and to the occurrence of an impact on the wheel to a receiver. An evaluation unit: collects the identifiers and rotational direction information and the driving speed, and on this basis, differentiates between identifiers of wheel electronics on the left and right vehicle side; differentiates impacts reported from wheel electronics on the left vehicle side, from impacts reported from wheel electronics on the right vehicle side; measures the time between impact signals reported from wheel electronics on the left or on the right vehicle side; multiplies the measured time by the driving speed measuring during this time; and checks whether the length formed by the multiplication coincides with an axle distance.
