In a hydraulic control device, a state determination unit of a control unit determines whether a second pump is in a boosting operation or in a transition state. If the state determination unit has determined that the second pump is in the boosting operation or in the transition state, a valve-opening detection unit determines whether a check valve is opened. If the valve-opening detection unit has determined that the check valve is opened, a controller stops the second pump or decreases the rotation number of the second pump.
