Abstract
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.
