Abstract

A system for coupling a trailer (2) to a motor vehicle (1), in particular a trailer (2) to a motor tractor (1), is provided with an image sensor (5), which is located in the coupling area. The coupling process involves connecting a trailer coupler (4) of the motor vehicle (1) and a tow bar (3) of the trailer (2), which is detected by an image sensor (5) detecting a movement of a locking element (8) associated with the trailer coupling (4). Thereupon a process of braking of the motor vehicle (1) is initiated.
