Abstract: An electric hydraulic brake includes: wheel brakes configured to supply braking force to wheels of a vehicle; a main braking unit including a reservoir which stores brake oil, and a master cylinder configured to form pressure of the brake oil in conjunction with a main brake motor; and a hydraulic controller comprising at least one pump configured to pump the brake oil in conjunction with an auxiliary brake motor, and configured to selectively transmit the pressure of the brake oil formed in the master cylinder or the pump to the wheel brakes. The hydraulic controller includes at least one auxiliary flow path which is connected at a first end thereof to the reservoir and is connected at a second end thereof to an inlet of the pump to transmit hydraulic pressure from the reservoir to the pump directly through the at least one auxiliary flow path.

Abstract: An electric hydraulic brake includes: wheel brakes configured to braking force to wheels of a vehicle; a reservoir storing brake oil; a master cylinder connected to the reservoir, and operated in conjunction with a main brake motor to generate pressure of the brake oil; a first controller configured to control the main brake motor; a hydraulic controller including a pump configured to form pressure of the brake oil in conjunction with an auxiliary brake motor, and a hydraulic block configured to selectively transmit the pressure of the brake oil formed in the master cylinder or the pump to the wheel brakes; and a second controller configured to control the auxiliary brake motor when the master cylinder or the first controller malfunctions. The hydraulic controller is provided with an auxiliary flow path to transmit the brake oil from the reservoir to the pump directly through the auxiliary flow path.
