Abstract

A device and a method determine an offset value which represents the offset of the output signal of a vehicle sensor, the sensor detecting at least one motion of a vehicle, and the output signal is analyzed at at least two different points in time. An additional signal is determined independently of the output signal, this signal also representing the motion of the vehicle. An arrangement is provided for analyzing the characteristic of the output signal, which depends on the longitudinal velocity of the vehicle, and the characteristic of the additional signal, which also depends on the longitudinal velocity of the vehicle, in order to determine the offset value.
