To improve work accuracy of work vehicles through automatic traveling without reducing harvest yield or reducing work efficiency.SOLUTION: When a work vehicle 1 automatically travels according to a target route (parallel route P1), and if an angular deviation Δθ of the work vehicle 1 with respect to the target route (parallel route P1) is greater than or equal to a predetermined angle θ, an automatic traveling system for work vehicles performs automatic reversal travel control for reversing work vehicle 1 by causing the work vehicle 1 to perform forward/backward switching control and steering control in a combined manner so as to reduce the angular deviation Δθ of the work vehicle 1 with respect to the target route (parallel route P1).SELECTED DRAWING: Figure 7

    【課題】収穫量の減少や作業効率の低下などを招くことなく自動走行による作業車両の作業精度を高める。【解決手段】作業車両用の自動走行システムは、目標経路(並列経路P1)に従って作業車両1を自動走行させる際に、目標経路(並列経路P1)に対する作業車両1の角度偏差Δθが所定角度θ以上の場合には、目標経路(並列経路P1)に対する作業車両1の角度偏差Δθを小さくするように作業車両1に前後進切り換え制御と操舵制御とを複合的に実行させて作業車両1を切り返し走行させる自動切り返し走行制御を行う。【選択図】図7
