Abstract
A warning system for a working machine including a movable load unit arrangement is disclosed. The warning system includes an illumination arrangement arranged to illuminate an area externally of the working machine and a load unit position prediction means arranged to determine a position of the load unit arrangement at a future point in time. The illumination arrangement is arranged to illuminate the area on the basis of the determined future position of the load unit arrangement.
Claims19
A warning system for a working machine, the working machine comprising a movable load unit arrangement, said warning system comprising an illumination arrangement arranged to illuminate an area externally of said working machine;
- wherein the warning system further comprises a load unit position prediction means arranged to determine a position of said load unit arrangement at a future point in time, said illumination arrangement being arranged to illuminate the area on the basis of the determined future position of the load unit arrangement;
- and
- wherein the illumination arrangement is arranged to illuminate a ground surface, said illuminated ground surface, the illuminated ground surface having an area corresponding to a vertical projection of a swept area formed by the movement of the load unit arrangement from a present position towards the determined future position.
(canceled)
A method for controlling a warning system of a working machine, the working machine comprising a movable load unit arrangement, said warning system comprising an illumination arrangement arranged to illuminate an area externally of said working machine, the method comprising:
- receiving a signal indicative of a moving operation of said load unit arrangement;
- determining a future position of said load unit arrangement based on the received signal of the moving operation of said load unit arrangement;
- and
- controlling said illumination arrangement to illuminate the area on the basis of the determined future position, the area corresponding to a vertical projection of a swept area formed by the movement of the load unit arrangement from a present position towards the determined future position.
A control unit arranged to control a warning system of a working machine, the working machine comprises a movable load unit arrangement, wherein the warning system comprises an illumination arrangement arranged to illuminate an area of a ground surface externally of said working machine;
- wherein the control unit is configured to:
- receive a signal indicative of a moving operation of said load unit arrangement;
- determine a future position of said load unit arrangement based on the received signal of the moving operation of said load unit arrangement;
- and
- control said illumination arrangement to illuminate the area on the basis of the determined future position, the area corresponding to a vertical projection of a swept area formed by the movement of the load unit arrangement from a present position towards the determined future position.
