Electronic brake system

An electronic brake system comprising:

• a pedal unit connected to a brake pedal and operated by a pedal effort of a driver;
• and
• a brake operating unit configured to generate pressure of a pressing medium for braking a vehicle based on a signal output in response to a displacement of the brake pedal,
• wherein the pedal unit comprises a pedal displacement actuator configured to displace the brake pedal from a first position to a second position when the vehicle enters an autonomous traveling mode in which a braking operation is not required by the driver,
• the brake operating unit comprises a first controller configured to control the generation of the pressure, and a second controller configured to control the generation of the pressure together with the first controller or on behalf of the first controller when the first controller fails, and
• when the vehicle enters the autonomous traveling mode, the first controller or the second controller controls the pedal displacement actuator to displace the brake pedal from the first position to the second position,
• wherein the first controller and the second controller transmit control signals for the pedal displacement actuator to the pedal displacement actuator through a controller area network (CAN) of the vehicle,
• the first controller is directly connected to the pedal displacement actuator through a first wire, the second controller is directly connected to the pedal displacement actuator through a second wire, and
• when the transmission of the control signals through the CAN fails, the first controller or the second controller directly transmits the control signal to the pedal displacement actuator through the first wire or the second wire.
