HYDRAULIC CONTROL UNIT FOR VEHICLE BRAKE SYSTEM

[Problem] The present invention relates to a hydraulic control unit that includes a pump for increasing a hydraulic pressure of a brake fluid. [Means for Resolution] The hydraulic control unit according to the present invention includes: a discharge channel from which the brake fluid is discharged, the brake fluid being pressurized by the pump; a pulsation reducing unit disposed in the middle of the discharge channel; and a controller controlling the pump and the pulsation reducing unit. The pulsation reducing unit includes: a valve housing; a fixed core fixed to the valve housing; a movable core received in the valve housing in an axially movable manner; a closing member interlocking with the movable core and closing the discharge channel; a coil disposed in a manner to surround the valve housing and the fixed core; and an inflow chamber which is formed by the valve housing and one end surface of the movable core, into which the brake fluid from the discharge channel flows, and whose volume can vary.
