Abstract

A method is for determining the offset value of the output signal of a vehicle sensor. The values of the output signal of the vehicle sensor are determined. The value range of the output signal of the vehicle sensor is divided into at least two partial ranges (intervals, classes). The values of the output signal are allocated to the partial ranges. The number of number quantities representing the values of the output signal allocated to the partial ranges is determined. The number quantities are determined by at least one low-pass filter.
