Abstract

A system and method for aligning the beam path of a beam-emitting sensor arranged on a motor vehicle. Convenient and nevertheless highly precise setting of the beam direction of the beam-emitting element is possible if, when the vehicle is stationary, an external aligning beam propagating along or parallel to an actual direction of travel of the motor vehicle 1 hits a strictly planar surface on the sensor which reflects the aligning beam, the incident aligning beam and the reflected aligning beam are made to overlap as a result of the position of the sensor being changed.
