description A method and a device for ascertaining a misalignment of at least one detection unit fastened on a vehicle with respect to the intended sensor main beam direction. The device includes at least one detection unit which emits signals and receives partial signals which have been reflected on objects, and ascertains the distance and the azimuth angle of the reflecting objects, and further includes an evaluation unit, to which the ascertained positions of the at least one detection unit are forwarded, and the determination of a misalignment takes place in the evaluation unit by comparing the stored alignment of the sensor main beam direction and the ascertained angle of the object extension with respect to the sensor main beam direction, this taking place under the assumption that the vehicle is moving on average, in parallel to the object extension, for the period during which the misalignment is ascertained.
