Abstract
Disclosed herein an electronic brake system includes a first block comprising a master cylinder having a first master piston connected to a brake pedal and a first master chamber whose volume is changed by a displacement of the first master piston; a second block comprising a pedal simulator, a hydraulic pressure supply device that generates a hydraulic pressure by operating a hydraulic piston according to an electrical signal, and a hydraulic control unit comprising a first hydraulic circuit that controls a hydraulic pressure transferred to two wheel cylinders and a second hydraulic circuit that controls a hydraulic pressure transferred to the other two wheel cylinders, the second block disposed to be spaced apart from the first block; a plurality of electronic control units (ECUs) that controls various devices and valves based on hydraulic pressure information and displacement information of the brake pedal; and a connection line having one end connected to the first block and the other end connected to the second block; wherein the connection line has one end connected to the first master chamber and the other end thereof connected to the pedal simulator side.
