Abstract
A electric brake system includes a main device that provides a first hydraulic pressure to a plurality of wheel cylinders respectively installed on a plurality of wheels, based on a position of a brake pedal; and art auxiliary device that provides a second hydraulic pressure to first and second wheel cylinders respectively installed on first and second wheels among the plurality of wheels based on the position of the brake pedal in a state in which the main device does not generate the first hydraulic pressure. The auxiliary device receives power from a power network different from that of the main device, and the auxiliary device controls at least one of first and second parking brakes respectively installed on third and fourth wheels among the plurality of wheels. In such an electric brake system, when the main device fails or is out of control, the auxiliary device may auxiliary generate the hydraulic pressure required for braking and may generate braking force using the parking brake.
