Abstract
Disclosed herein is an electric brake system for a vehicle including a reservoir, a master cylinder, an input rod, and a pedal displacement sensor. The electric brake system includes a pressure supply unit to receive oil and to output an electrical signal through the pedal displacement sensor, a hydraulic control unit to perform braking of a wheel, first and second switching valves connected to a channel connecting the pressure supply unit to the hydraulic control unit, a simulator connected to the master cylinder, and an electronic control unit to control the motor and the valves. The pressure supply unit includes a pressure chamber, a hydraulic piston arranged in the pressure chamber, a hydraulic spring to elastically support the hydraulic piston, the motor to generate rotational force, and a ball-screw member to convert rotational motion of the motor into rectilinear motion. The hydraulic piston is connected to the screw.
