To change a posture of a working vehicle when transitioning from a turning route to a working route to a posture suitable for working travel in the working route from an initial stage of the working vehicle transitioning from the turning route to the working route.SOLUTION: An automatic travel system includes an automatic travel control unit 40 for controlling a working vehicle V to automatically travel in accordance with a target route P. The target route P includes a turning route Pt and a second working route Pw to travel subsequent to the turning route Pt. The automatic travel control unit 40 controls the working vehicle V automatically travelling in accordance with the turning route Pt to automatically travel in accordance with the second working route Pw from a position prior to a second connection point Pb between the turning route Pt and a second working route Pw.SELECTED DRAWING: Figure 20 【課題】旋回経路から作業経路に移行する際の作業車両の姿勢を、作業車両が旋回経路から作業経路に移行する初期段階から作業経路での作業走行に適した姿勢にする。【解決手段】自動走行システムは、作業車両Ｖを目標経路Ｐに従って自動走行させる自動走行制御部４０を有する。目標経路Ｐには、旋回経路Ｐｔと、旋回経路Ｐｔの次に走行させる第２作業経路Ｐｗとが含まれている。自動走行制御部４０は、旋回経路Ｐｔに従って自動走行する作業車両Ｖを、旋回経路Ｐｔと第２作業経路Ｐｗとの第２接続地点Ｐｂよりも手前の位置から第２作業経路Ｐｗに従って自動走行させる。【選択図】図２０
