AUTOMATIC RUNNING WORK VEHICLE

摘要

An automatic running work vehicle in which both front wheels 2 and rear wheels 3 can be steered and which is provided with a follower sensor A for detecting the boundary between an unworked area and a worked area and an orientation sensor 5 for detecting the running direction so as to run automatically along the boundary. Based on the result of detection of the boundary by the follower sensor and on the result of detection of the orientation of the vehicle body by the orientation sensor, the front and rear wheels are steered automatically to correct the running direction automatically. If the orientation is within a prescribed range of a desired vehicle front and rear wheels are adjusted equally to give translational movement; if outside the range a different adjustment is applied to front and rear to effect a directional correction also. The vehicle may be a mower.
