Abstract:
A method of determining an offset value of an output signal of a vehicle sensor, comprising the steps of:determining at least one value of the output signal of the vehicle sensor; dividing a value range of the output signal of the vehicle sensor into at least two partial ranges; allocating the value of the output signal of the vehicle sensor to the partial ranges; determining a number of number quantities representing the values of the output signal of the vehicle sensor allocated to the partial ranges; triggering a low-pass filter, in whose allocated partial range the value of the output signal determined at a sampling time falls, with a first input signal; and triggering at least another low-pass filter, in whose allocated value ranges the value of the output signal determined at the same sampling time does not fall, with a second input signal, the second input signal differing from the first input signal; wherein the number of number quantities are determined in the determining step by at least one of the low-pass filters, and wherein the low-pass filters are allocated to the at least two partial ranges, each of the low-pass filters being configured to determine the number quantity allocated to its partial range.
