Abstract
This work vehicle is provided with an emergency brake function for quickly bringing said work vehicle to an emergency stop when an abnormality has occurred inside of the vehicle. The work vehicle comprises: 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 that controls the operation of the electric actuator. When in an autonomous travel mode, the control unit controls the operation of the electric actuator and switches the foot brake from the release state to the braking state when an abnormality is detected inside of the vehicle on the basis of detection information from a vehicle state detection device for detecting the state of each part of the vehicle, or when an emergency stop command is acquired from a wireless communication device set so as to be capable of wireless communication with the autonomous travel unit.
