Method and system for controlling movement of an autonomous load-carrier vehicle

A system for controlling movement of an autonomous load-carrier vehicle along a pre-set path at a construction site, the system comprising:

• a positioning sensor arranged onto a loader vehicle intended to be used for loading the autonomous load-carrier vehicle, wherein the positioning sensor is configured to provide a control signal indicative of a current position of the loader vehicle;
• a control system configured to:
• handle the control signal provided by the positioning sensor arranged onto the loader vehicle;
• determine a point on the pre-set path that is closest to the current position of the loader vehicle;
• set a suitable loading position for the autonomous load-carrier vehicle at a point along the pre-set path based on the point on the pre-set path that is closest to the current position of the loader vehicle;
• wherein the suitable loading position corresponds to the point closest to the current position of the loader vehicle or is a point in the immediate surroundings of said closest point that, when the autonomous load-carrier vehicle stops at the suitable loading position, allows pre-set aligning of a part of the autonomous load-carrier vehicle in relation to the loader vehicle when the loader vehicle is positioned close to the pre-set path;
• and
• control the autonomous load-carrier vehicle so as to move along the pre-set path and stop at the suitable loading position.
