DRAW BAR WITH AN EVALUATION DEVICE

The invention relates to a trailer coupling for a towing vehicle (90), having a coupling bracket (14; 114; 214) which comprises in particular a coupling arm, at whose free end a coupling element (23), in particular a coupling ball (22), is arranged for attaching a trailer (92), and which is arranged fixedly or movably on a bracket (11; 111) attached or attachable to the towing vehicle (90), and having at least one force sensor (30) for detecting a force acting in particular through the trailer (92) on the coupling element (23) and for outputting a force signal (33) representing the force. An evaluation device (50; 150) is provided which is designed to determine at least one value, in particular a drawbar load acting on the trailer coupling and/or a trailer mass value of the trailer (92), on the basis of the force signal (33) and an angle value.
