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.

Abstract: A lubrication system for a utility vehicle with a lubricating unit having a lubricant reservoir, a pump, and a distributor attached thereto to which supply lines to a plurality of lubrication points can be attached, and comprising a control module having at least two lubrication programs stored therein, wherein the pump initiates an ejection of grease in a cycle predetermined by the respective lubrication program. The object of the invention is to improve upon a lubrication system such that a change between lubrication programs and optionally the execution of an intermediate lubrication using an automatic lubrication system is possible during driving operations independent of the presence of a higher level on-board electronics system.

Abstract: A fifth-wheel coupling (1) having a coupling plate (2) with an entry opening (4) for a king pin (5) includes an at least single-part locking device (100) for fastening the king pin (5) and a fixing element which engages on the locking device, which fixing element can be moved from a locking position into an open position and vice versa. A securing device (15) with a blocking element (40, 400) is provided, which blocking element (40, 400) can be moved from a rest position into a blocking position and vice versa, wherein the blocking element (40, 400) projects into the entry opening (4) at least in the blocking position.

Abstract: An anti-theft security device for a vehicle coupling, in particular a fifth wheel coupling (1), includes a security apparatus (2) and a control apparatus (3) which are electrically connected to each other. The control device (3) is connected to at least one vehicle-side system (10a, b, c) having an emergency function. Upon the triggering of at least one emergency function of the vehicle-side system, the control apparatus (3) deactivates the control apparatus (2) directly or indirectly.

Abstract: A support jack with a vertically telescopically displaceable supporting element having an outer sleeve and an inner sleeve is described. For the operator, it is sometimes hard to discern whether the support jacks find an adequate abutment on the ground. In an extreme case, the support jack sinks into the ground under the load of the vehicle. The vehicle is then no longer adequately supported and can tip over. For this reason, the object of the invention is to develop a support jack in such a way that secure standing is already discernible for the operator during extension of the supporting element. According to the invention, the object is achieved with a support jack in which a supporting load indicator with a pressure element is arranged on the supporting element, the pressure element triggering a signal when a predefinable supporting force is reached.

Abstract: A coupling system for connecting supply lines between a trailer and a tractor vehicle, with a socket which is arranged on the tractor vehicle and a support element, having a plug, which is arranged on the trailer. The invention is based on the problem of providing a robustly operating coupling system in which an automatic connection of all of the provided supply lines is possible. The problem is solved by a coupling system in which the socket is arranged in a positionally fixed manner on the tractor vehicle, the plug is guided in a laterally moveable manner in the support element, and the plug can be placed into a connecting position with the socket by an actuator which is arranged on the tractor vehicle.
