Method and device for mismatch recognition in a vehicle radar system or a vehicle sensor system

A device for detecting a misalignment in a motor vehicle radar system, comprising:

• an arrangement for emitting an electromagnetic wave;
• an arrangement for receiving an electromagnetic wave reflected by a stationary object to detect the stationary object;
• an arrangement for determining on the basis of the emitted electromagnetic wave and the reflected electromagnetic wave a relative velocity between the detected stationary object and a motor vehicle and one of the following:
• a set including a relative angle and a relative distance between the detected stationary object and a reference axis of the motor vehicle, and
• a set including a longitudinal displacement and a transverse displacement between the detected stationary object and the reference axis;
• and
• an arrangement for determining a correction value for the relative angle on the basis of one of:
• a set including the relative angle, the relative distance, and a velocity of the motor vehicle, and
• a set including the longitudinal displacement, the transverse displacement, and the velocity of the motor vehicle.
