Abstract

In the case of a collision protection method for a displaceable vehicle part of a vehicle, during the displacement of the vehicle part, a focused light beam is deflected by a light deflection unit along a predefined scanning path and reflected radiation of the same light beam is detected by a light-sensitive sensor to scan a travel path region upstream from the vehicle part. The presence or absence of an obstruction in the upstream travel path region is concluded on the basis of the reflected radiation, wherein the displacement is stopped or reversed if an obstruction is recognized in the upstream travel path region.
