Method and control system for a displacement device, taking into account the relative angular position of a tractor and semi-trailer
First Claim
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.

Abstract
A method and a system for controlling a displacement device for a fifth wheel coupling disposed on a tractor vehicle are described, wherewith the displacement device has 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); wherewith a measurement is made for determining the angle between the tractor and semi-trailer, the measurement signal is converted in the control device to a control signal, and thereby an operation of the motorized drive unit and/or the adjusting member is initiated. The underlying problem of the invention was to devise a method and a control system which minimize the risk of the semi-trailer striking against the cab of the tractor. One way in which this problem is solved according to the invention is that, from the measurement signal, an angular or distance timewise rate of change is generated in the control device, or such a timewise rate of change is transmitted to the control device.

7. A control system comprised of:
-
a displacement device for a fifth wheel coupling disposed on a tractor vehicle, which device is comprised of;
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);
wherewith the control device is connected to at least one sensor which generates a measurement value for determining the angle between the tractor and semi-trailer, and said control device cooperates with the drive unit and/or the adjusting member;wherein the control device calculates a value corresponding to a time rate of change of an angle or the time rate of change of a distance, from the change in the measurement value. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 19, 20)
