Electric hydraulic brake

An electric hydraulic brake comprising:

• a plurality of wheel brakes configured to supply braking force to wheels of a vehicle;
• a reservoir storing brake oil;
• a master cylinder connected to the reservoir and configured to generate hydraulic pressure in cooperation with a motor;
• a hydraulic circuit fluidically connected to the master cylinder and configured to selectively transmit the hydraulic pressure to the plurality of wheel brakes, the hydraulic circuit including a front wheel hydraulic circuit to transmit the hydraulic pressure to a pair of front wheel brakes, a rear wheel hydraulic circuit to transmit the hydraulic pressure to a pair of rear wheel brakes, and a plurality of solenoid valves;
• a first controller electrically connected to the motor and configured to control the motor and the front wheel hydraulic circuit and the rear wheel hydraulic circuit of the hydraulic circuit in accordance with braking input;
• and
• a second controller electrically connected to the motor and configured to control the motor and the front wheel hydraulic circuit in response that the first controller malfunctions,
• wherein the hydraulic circuit includes a mixing flow path connecting the front wheel hydraulic circuit and the rear wheel hydraulic circuit,
• wherein a mixing valve that is one of the plurality of solenoid valves installed in the mixing flow path and configured to selectively transmit the hydraulic pressure to the plurality of wheel brakes, and
• wherein the mixing valve remains closed when the first controller malfunctions.
