CRAWLER VEHICLE AND CONTROL METHOD TO CONTROL SAID CRAWLER VEHICLE

A crawler vehicle having a frame; at least one working tool which is connected to the frame and is configured to perform a processing of a surface to be worked and a position sensor configured to detect a plurality of positions of the crawler vehicle on the surface to be worked. The crawler vehicle has a control unit configured to reconstruct a trajectory travelled by the crawler vehicle on the surface to be worked as a function of the positions of the crawler vehicle detected by the position sensor and to calculate a reference position to be reached and/or a reference trajectory to be travelled as a function of the positions detected by the position sensor and of the reconstructed trajectory travelled. The crawler vehicle has a display device configured to reproduce a first visual indicator indicative of the calculated reference position and/or of the calculated reference trajectory.
