Abstract: Provided is an automatic travel system for a work vehicle, wherein: a control unit that causes the work vehicle to automatically travel according to a target path includes a target position setting unit that sets a target travel position to a predetermined position separated by a predetermined distance in an advancing direction from a current position of the work vehicle, and an automatic steering controller that controls operations of a steering unit so that that work vehicle follows the target travel position; and the target position setting unit determines whether the target travel position has reached an end position of a turning path connected to a straight path and, if a determination is made that the target travel position has reached the end position of the turning path, then changes the setting of the target travel position from the position on the turning path to a position on the straight path.

Abstract: A positioning unit measures the position of a tractor. An automatic traveling control unit causes the tractor to automatically travel according to a target route on the basis of positioning information of the positioning unit. In the case where the tractor changes its direction on a direction change route, when the distance from a field to an end position at which the front-rear direction of the tractor is switched is less than a predetermined distance, the automatic traveling controller executes deceleration processing of decelerating a target speed of the tractor toward the end position.
