Abstract

A method for detecting misalignment in a motor vehicle sensor system, in which signals are emitted, signals reflected by a stationary object are received, and a relative angle and a relative distance or a longitudinal displacement and a transverse displacement between the detected object and a reference axis of the motor vehicle as well as a relative velocity between the detected object and the motor vehicle are determined on the basis of the signals emitted and received. A correction value is determined for the relative angle on the basis of the relative angle, the relative distance, and a velocity of the vehicle in question or on the basis of the longitudinal displacement, the transverse displacement, and the vehicle's own velocity.
