METHOD FOR MOVING BACKWARDS A COMBINATION AND ASSEMBLY FOR ASSISTING THE BACKWARD MOVEMENT OF THE COMBINATION
First Claim
1. A method for moving a combination backwards into an area, the combination comprising a propelled vehicle and an implement mechanically coupled with the vehicle by a towing unit, the vehicle comprising a steering mechanism arranged to change the traveling direction of the propelled vehicle, the implement being is pivotal with respect to the vehicle around a pivoting axis perpendicular to the ground, said method comprising the steps of:
- moving the combination backwards with the propelled vehicle into the area along a path;
providing the implement in front of the vehicle when the combination is moved backwards,positioning, while the combination is moved backwards, the following sequence at least once;
measuring a value indicative of the pivoting angle of the implement with respect to the vehicle or of the change of this pivoting angle with a pivoting angle sensor;
measuring a value indicative of the distance to a border of the area in at least one direction with a distance sensor;
measuring a value indicative of the length of a path along which the implement is moved with a path sensor;
automatically calculating a required change of the travelling direction of the vehicle with a computer; and
outputting a signal indicative of the required change of the travelling direction,wherein the computer calculates the required change on the basis of said measured pivoting angle or said pivoting angle change, said measured length of the path, and said measured distance, andwherein the distance sensor, the path sensor, and the computer are implemented on board of the implement and the pivoting angle sensor is implemented on board of the combination.

Abstract
A method is provided for moving backwards a combination and an assembly is provided for assisting the backward movement of a combination into an area, which might be surrounded by obstacles. The combination includes a propelled vehicle and an implement. The implement can pivot with respect to the vehicle. The vehicle moves the combination backwards. A pivoting angle sensor on board of the combination measures the pivoting angle of the implement with respect to the vehicle. A distance sensor on board of the implement measures the distance to a border of the area. A path sensor on board of the implement measures the length of a path along which the implement is moved. A computer on board of the implement calculates a required change of the travelling direction of the vehicle by using the pivoting angle, the path length, and the measured distance. A signal indicative of the required change is transmitted to an output unit.
