Classification: CPC F  H | IPC F  H

Claim 7:
8. A hydraulic pressure generation device, comprising:
a hydraulic pressure pump;
a motor, driving the hydraulic pressure pump; and
a motor control device, controlling the motor,
wherein the motor control device comprises:
a current control part, performing current control for rotating the motor from a stop state;
a rotation speed calculation part, calculating an actual rotation speed of the motor;
an acquisition part, acquiring a target rotation speed, which is a target value relating a rotation speed of the motor;
a speed control part, performing speed control of the motor, so that the actual rotation speed of the motor calculated by the rotation speed calculation part becomes the target rotation speed acquired by the acquisition part; and
a correction part, at a time of a transition from a current control state by the current control part to the speed control performed by the speed control part, correcting the target rotation speed acquired by the acquisition part based on a relation between the actual rotation speed of the motor calculated by the rotation speed calculation part and the target rotation speed acquired by the acquisition part,
wherein in a case where the target rotation speed acquired by the acquisition part is corrected by the correction part, the speed control part performs the speed control, so that the actual rotation speed of the motor calculated by the rotation speed calculation part becomes the target rotation speed corrected by the correction part.
