PURPOSE: A hydraulic active booster is provided to prevent changes in pedal feeling caused by the liquid pressure change of a master cylinder during regenerative braking. CONSTITUTION: A hydraulic active booster comprises an input shaft(20), a pedal simulator(60), a master cylinder(50), and an oil supply device(40). The input shaft is connected to a brake pedal(10). The pedal simulator outputs a reaction force to the brake pedal. The master cylinder comprises a control plunger(25), a first piston(52), a second piston(55), and a master cylinder housing(51). The control plunger has a receiving groove(25a) in which a protrusion of the first piston is accommodated. The oil supply device supplies oil to the pedal simulator. |
