This work vehicle is provided with: a machine body; a traveling device (12) provided to the machine body; a machine body position calculation unit (32) that calculates the position of the machine body and the travel orientation of the machine body; an information acquisition unit (24) that acquires predetermined turning time information (40) during turning travel; and an automatic turning travel control unit (36) for controlling the steering angle of the travel device (12) during turning travel in accordance with a predetermined flow path, and for controlling the steering angle of the travel device (12) during turning travel when the angular difference between the travel orientation and the target orientation of a straight path to travel following the turning travel is equal to or less than a predetermined threshold value (45). The automatic turning travel control unit (36) performs control for restoring the steering angle so that the machine body travels straight, and changes the threshold value on the basis of the turning time information (40).

    本发明的作业车具备:机体;行驶装置(12),设于机体;机体位置计算部(32),计算机体的位置和机体的行驶方位;信息获取部(24),获取转弯行驶时的规定的转弯时信息(40);以及自动转弯行驶控制部(36),按照预设的规定的流程控制转弯行驶中的行驶装置(12)的转向角度,在转弯行驶中,当接着转弯行驶要行驶的直线路径的目标方位与行驶方位的角度差为规定的阈值(45)以下时,自动转弯行驶控制部(36)进行使转向角度复原以使机体直行行驶的控制,自动转弯行驶控制部(36)根据转弯时信息(40)来变更阈值。
