Claim 17:
18. A method for a monitoring of a coupling state of a coupling element, in particular a coupling bolt, preferably a kingpin, of a trailer, in particular a semitrailer, with a corresponding coupling element of a towing vehicle, in particular a semitrailer tractor, with a detection step in which a position of the coupling element, which is arranged and/or in motion in a field of vision of a sensor, is detected or in which a position of the corresponding coupling element, which is arranged and/or in motion in the field of vision of the sensor is detected, wherein the position of the coupling element or the position of the corresponding coupling element is detected in the detection step by a sensor that is realized as an ultra-wideband sensor, and wherein a control and/or regulation unit evaluates a reflection signal of the ultra-wideband sensor and, depending on the evaluated reflection signal, outputs a coupling confirmation signal, an uncoupling confirmation signal or a “coupling process under way” signal to the towing vehicle.
