The invention relates to a trailer hitching device which comprises a base. A hook pivotally attached to the base; a motor that can be used to rotate the hook from a first position, preferably a working position, in which the trailer can be attached to the hook, to a second position, preferably a parking position, in which no trailer can be attached to the hook; a control unit for controlling the motor, capable of activating the motor by means of a test pulse, such that the hook in the first position is subjected to a force during the test pulse, the force having a direction opposite to a direction of movement in which the hook is moved from the first position into the second position; and a current or voltage sensor for detecting a current received by the motor or a voltage applied to the motor during the test pulse, the current or voltage sensor being connected to the motor, and: the current or voltage sensor being connected to an input of the control unit; or the current or voltage sensor is part of the control unit and is connected to the motor via the input of the control unit.

    本发明涉及一种拖车挂接装置,包括:●底座;●可枢转地附接至底座的钩;●马达,可以用来使钩从第一位置旋转至第二位置,第一位置优选为工作位置,其中拖车能附接至钩,第二位置优选为停放位置,其中没有拖车能附接至钩;●用于控制马达的控制单元,其能够通过测试脉冲启动马达,以使位于第一位置中的钩在测试脉冲期间受到力的作用,该力具有的方向与使钩从第一位置运动至第二位置中的运动方向相反;以及●电流或电压传感器,用于检测在测试脉冲期间马达接收的电流或施加至马达的电压,电流或电压传感器连接至马达,并且:电流或电压传感器连接至控制单元的输入端;或电流或电压传感器为控制单元的一部分并经由控制单元的输入端与马达建立连接。
