Abstract: A redundant vehicle braking system and its electronic control unit and control method thereof is disclosed. The redundant braking system is coupled to the main braking system of the vehicle. The electronic control unit comprises: a receiving module configured to receive a status signal indicating the status of the main braking system and a sensor signal indicating a driver input condition to the brake pedal and a vehicle speed condition; an activation module configured to activate the braking assist function of the redundant braking system when it is judged that the main braking system has entered a mechanical backup state based on the status signal; and a braking assist module configured to, upon activation of the braking assist function, execute a corresponding one of a plurality of braking assist modes based on the sensor signal, wherein the plurality of braking assist modes comprise: a standby mode, a first-assist adjustable mode, a second-assist adjustable mode, and a braking pressure holding mode.
