A target HST pressure specifying unit specifies a target HST pressure which is a target pressure of HST. A measurement value acquisition unit acquires an actual HST pressure which is a measurement value of a pressure of the HST. A brake torque determination unit determines a brake torque based on the target HST pressure and the actual HST pressure, the brake torque which is a torque consumed by a hydraulic pump. A pump control unit controls the hydraulic pump based on the brake torque.
