ELECTRONIC BRAKE SYSTEM AND OPERATION METHOD

The present disclosure relates to an electronic brake system and an operation method thereof. The electronic brake system includes a reservoir in which a fluid is stored, a hydraulic pressure supply device configured to generate a hydraulic pressure by operating a hydraulic piston in response to a signal from a pedal displacement sensor detecting a displacement of a brake pedal, a hydraulic control unit including a first hydraulic unit configured to control the hydraulic pressure to be transferred from the hydraulic pressure supply device to a first hydraulic circuit including two wheel cylinders, and a second hydraulic unit configured to control the hydraulic pressure to be transferred from the hydraulic pressure supply device to a second hydraulic circuit including other two wheel cylinders.
