The trailer coupling has a coupling ball with a ball body (100), which has a ball surface (110) extending between a ball stud and an upper end surface (104) of the ball body. The ball surface has a sensing zone (126), in which multiple different detection locations lie, such that each detection location is associated to a sensor unit, which is stationarily arranged below the ball surface in the ball body. Each sensor unit is formed, such that it detects an existing body in a close range (140) above the ball surface at the respective detection location. |
