Title: WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE
Abstract:
A wheel loader (1) comprising steering cylinders (21, 22), a pilot valve (42), a joystick lever (24), a pressure detection unit (29), a force application unit (27), and a control unit (28). The pilot valve (42) controls the flow rate for oil supplied to the steering cylinders (21, 22). The joystick lever (24) is operated by an operator when the steering angle (θs) is changed and controls the pilot valve (42). The pressure detection unit (29) detects pressure generated in the steering cylinders (21, 22). The force application unit (27) applies an auxiliary force or a reaction force to the operation of the joystick lever (24). The control unit (28) controls the force application unit (27) so as to generate resistance against the operation of the joystick lever (24), on the basis of a pressure value detected by the pressure detection unit (29).
