PROBLEM TO BE SOLVED: To provide an automatic traveling control system capable of calculating a turning output according to a state of a work vehicle. A route calculation unit that calculates a target traveling route that passes through an unworked area, and a lateral distance that is a distance between the target traveling route and the working vehicle so that the working vehicle automatically travels along the target traveling route. The traveling control unit 24 includes a traveling control unit 24 that controls traveling of the work vehicle by calculating a turning output based on the deviation, and a detection unit 25 that detects a state of the work vehicle. When entering the unworked area from the area, the correspondence between the lateral deviation and the turning output is determined based on the state detected by the detection unit 25.
