An automatic steering system which reduces formation of a wheel track by changing a relative position of a vehicle with respect to a road. A reference line is provided along a road so that a vehicle moves along the reference line. The vehicle moves on the road while an amount of shift from the reference line is controlled to be equal to a target amount of shift. The amount of shift is a distance between a predetermined position of the vehicle and the reference line. A moving line of the vehicle is fluctuated with respect to time in a direction substantially perpendicular to an extending direction of the reference line. Alternatively, the reference line may be shifted in a direction substantially perpendicular to the extending direction of the reference line.

[ What is claimed is:] [1.] An automatic steering system comprising:a reference line provided along a road providing to a vehicle traveling on the road an indication of the path along which the road extends;means for determining a target amount of shift from the reference line in a direction substantially perpendicular to the reference line, wherein the amount of shift is a distance in a direction substantially perpendicular to the reference line between a position of the vehicle and the reference line;means for controlling a position of the vehicle relative to the reference line to achieve the target amount of shift; andfluctuating means for changing the target amount of shift over time to change over time a moving line over which the vehicle is to be moved.
