Abstract: An alignment system for approaching a vehicle to a target object spatially spaced therefrom, including an object detection device attached to the vehicle and a coupling element, which in an end position detachably holds the target object, the object detection device being aligned in the direction of the target object and the data from the object detection device being used to generate an image in which the target object together with a guide marker can be seen during the approach of the vehicle. The guide marker is applied to at least one component of the vehicle arranged in an entry area of the coupling element.

Abstract: A coupling device for a towing vehicle with an object detection device attached to the coupling device, wherein the coupling device has a coupling body in form of a fifth wheel plate and a locking mechanism, with which a coupling device in form of a kingpin is releasably held on the coupling body in its end position (E), wherein the coupling body includes an available space which is limited by a coupling device guiding contour and extends along a longitudinal axis (x), wherein the coupling device is at least partially immersed during coupling into the available space until reaching an end position (E).

Abstract: A driver assistance system for coupling a trailer to a towing vehicle is described, including a video camera attached to the towing vehicle and an associated display device in the driver's field of vision, in whose video image a static guide marking is displayed along which a coupling mouth arranged on the towing vehicle can be contacted with a drawbar eye held on the trailer by a drawbar. Providing a driver assistance system which helps the driver estimating the three-dimensional position of the drawbar eye in relation to the towing vehicle while rearwards approaching a trailer. The video camera is arranged at a vertical distance from the coupling and the guide marking is formed by two beam corridors arranged on both sides of the vehicle's longitudinal axis converging towards one another in the rearward direction of the towing vehicle.
