Abstract
A rotational speed of an electric motor is memorized at a memory unit as a set rotational speed for allowing a minimum required volume of brake fluid to be discharged from the pumps in a state where the output hydraulic pressure of the master cylinder is highest, and an energizing duty ratio for the electric motor which is designed so as to rotate the electric motor at the set rotational speed is determined at a duty ratio determining unit in response to an applied voltage detected at a voltage detecting unit A motor control unit controls the energizing of the electric motor from a battery in accordance with the energizing duty ratio determined at the duty ratio determining unit
