Abstract
Examples relate to a hydraulic control unit that includes a pump for increasing a hydraulic pressure of a brake fluid. The hydraulic control unit includes a discharge channel from which the brake fluid pressurized by a pump is discharged, 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 formed by the valve housing and one end surface of the movable core, into which the brake fluid flows, and whose volume can vary.
