Abstract

A method for compensating sensor tolerances of accelerometers of a vehicle. The method includes following steps: recording of measurement signals of at least three similarly oriented accelerometers, calculation of an acceleration (ab,z) at a reference position in the spatial direction, which corresponds to the orientation of the accelerometers, low-pass filtering of the measurement signals, determination of tolerance parameters (cx, cy, cz) of each sensor via an optimization method with the aid of the calculated acceleration (ab,z) at the reference position, and calculation of the adjusted measurement signals from the recorded measurement signals and the tolerance parameters (cx, cy, cz).
