1. A method of controlling a displacement device for a fifth wheel coupling disposed on a tractor vehicle, wherewith the displacement device comprises:

  • a lower structure having at least one guide rail oriented in the direction of travel, a movable carriage which supports the fifth wheel coupling and engages the guide rail(s), and a control device connected to a motorized drive unit for displacing the carriage and also connected to an adjusting member for fixing the carriage with respect to the guide rail(s);

    comprising the steps of;

    making a measurement for determining an angle between the tractor and semi-trailer, converting the measurement signal in the control device to a control signal, and thereby initiating an operation of the motorized drive unit and/or the adjusting member;

    generating in the control device, from the measurement signal, an angular or distance timewise rate of change, or such a timewise rate of change is transmitted to the control device.
