An electronic brake system is disclosed. According to an embodiment of the present invention, the electronic brake system comprises: a reservoir which stores oil therein; a master cylinder which is coupled to the reservoir and has first and second hydraulic ports; a pedal displacement sensor; a simulation device which is connected to the master cylinder; a hydraulic pressure supply device which generates hydraulic pressure by pressing first and second hydraulic chambers formed in both sides of a double-acting piston; a hydraulic pressure control unit which has first and second hydraulic circuits and controls the flow of hydraulic pressure transferred to a caliper brake; and an electronic control unit which controls the motor and the valves on the basis of the hydraulic pressure information and pedal displacement information. Thus, the present invention rapidly generates pressure when boosting the system and enables a precise pressure control. |
