An electronic brake system includes: a master cylinder connected to a brake pedal; a hydraulic pressure supply device including a motor that generates a rotational force and a hydraulic piston movably accommodated in a pressure chamber, and configured to generate a hydraulic pressure by a movement of the hydraulic piston; a hydraulic control unit configured to control a flow of the hydraulic pressure transferred to a wheel cylinder from the hydraulic pressure supply device; a hydraulic block in which the master cylinder, the hydraulic pressure supply device and the hydraulic control unit are integrated; and a controller configured to control the motor and the hydraulic control unit, wherein, during an anti-lock braking system (ABS) operation, the controller is configured to generate vibration in the motor by supplying the motor with an excitation current for exciting the motor to notify a driver of the ABS operation by vibration of the brake pedal.
