Title:
ELECTRONIC BRAKE SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/080402
Kind Code:
A1
Abstract:
An electronic brake system according to one embodiment comprises: a reservoir in which a pressure medium is stored; a master cylinder for discharging the pressure medium according to the pushing force of a brake pedal; a hydraulic pressure supply device for generating hydraulic pressure by operating a hydraulic piston by means of an electrical signal outputted in correspondence to the displacement of the brake pedal; a hydraulic control unit which is connected to the hydraulic pressure supply device and which controls the flow of the hydraulic pressure transmitted to a wheel cylinder; a pedal simulator which is connected to the master cylinder and which provides a reaction force against the brake pedal; a simulator valve for opening/closing a flow path that connects the master cylinder and the pedal simulator; a cut valve for opening/closing a flow path that connects the master cylinder and the hydraulic control unit; a pedal displacement sensor for detecting the displacement information about the brake pedal; a pressure sensor for detecting the pressure information about the pedal simulator; and a control unit for compensating, when the cut valve is closed and the simulator valve is opened, for target pressure according to the brake pedal displacement on the basis of the brake pedal displacement information detected through the pedal displacement sensor and the pedal simulator pressure information detected through the pressure sensor, and driving the hydraulic pressure supply device according to the compensated target pressure.
