Abstract
A control device that includes an electronic control unit that is configured to perform, when specific control that causes a change in a state of a hydraulic circuit in the hydraulic control device that involves an increase in hydraulic pressure at the discharge port is performed in a state in which a rotational speed of the electric motor is a first rotational speed, torque increase control that controls drive of the electric motor such that torque of the electric motor starts to increase before hydraulic pressure at the discharge port increases by the specific control.
