METHOD FOR DETECTING AND/OR CONTROLLING A COUPLING PROCESS BETWEEN A TOWING VEHICLE AND A VEHICLE TRAILER

A method for identifying and/or controlling a coupling procedure between a towing vehicle and a vehicle trailer that is embodied as a semi-trailer includes determining a contact between the coupling plate of the towing vehicle and the fifth wheel plate of the semi-trailer by way of a change of an adjusting speed with which a distance between the at least one rear axle of the towing vehicle and the locking device of the coupling plate is increased. The towing vehicle comprises a coupling plate and the semi-trailer comprises a fifth wheel plate having a king pin that is fixed in the coupled state in a locking device of the coupling plate and the towing vehicle comprises a pneumatic level controlling device by way of which it is possible to set different distances between at least one rear axle of the towing vehicle and the locking device of the coupling plate.
