Abstract

The present invention makes it possible to avoid the risk of a brake operation system for emergency stopping not operating normally during autonomous travel of a work vehicle. A work vehicle is provided with: a foot brake for braking left and right rear wheels; an autonomous travel unit that enables autonomous travel of the vehicle; and an electric actuator for switching the foot brake between a braking state and a release state. The autonomous travel unit comprises a control unit for controlling the operation of the electric actuator. When an autonomous travel mode is selected by human operation of a mode selection unit, the control unit performs operation verification processing in which it is verified by operation control of the electric actuator whether the foot brake is operating normally, and when it is verified that the foot brake is operating normally in the operation verification processing, said control unit transitions to a completed operation verification state and allows the travel mode to transition from a manual travel mode to the autonomous travel mode.
