ELECTRIC BRAKE SYSTEM AND OPERATION METHOD

WIPO Patent Application WO/2020/242071

A1

Disclosed is an electric brake system. An electric brake system, according to the present embodiment, may be provided by comprising: a reservoir in which a pressurizing medium is stored; an integrated master cylinder including a master chamber and a simulation chamber; a reservoir flow path which connects the integrated master cylinder and the reservoir; a liquid pressure supply apparatus which operates a hydraulic piston by an electric signal output in response to a displacement of a brake pedal so as to generate a liquid pressure, the liquid pressure supply apparatus including a first pressure chamber which is provided on one side of the hydraulic piston movably accommodated inside a cylinder block and which is connected to at least one wheel cylinder, and a second pressure chamber provided on the other side of the hydraulic piston and connected to at least one wheel cylinder; a hydraulic control unit including a first hydraulic circuit which controls the liquid pressure transferred to two wheel cylinders and a second hydraulic circuit which controls the liquid pressure transferred to two other wheel cylinders; and an electronic control unit which controls valves on the basis of liquid pressure information and displacement information of the brake pedal.
