PROBLEM TO BE SOLVED: To suppress a decrease in work efficiency. A work vehicle according to an embodiment is provided on a traveling vehicle body, a work machine that is mounted on a rear portion of the traveling vehicle body so as to be able to move up and down, a control unit that controls lifting and lowering of the working machine, and a rear portion of the traveling vehicle body. A rear sensor that detects an object existing behind the traveling vehicle body and a positioning device that measures the position of the traveling vehicle body are provided.The control unit raises the work implement when the traveling vehicle body turns, and controls the planned traveling route of the traveling vehicle body. Storing, based on the measurement result of the positioning device, having an autonomous driving mode for performing work while autonomously traveling along the stored planned traveling route, and when the traveling vehicle body approaches a turning point during the autonomous driving mode, Stop detection by the rear sensor.
