The invention relates to an electronic mechanical brake redundancy control system and a control method, and aims to solve the technical problem that in the prior art, redundancy braking and parking requirements under a complete failure scene of a vehicle control unit are not considered. Comprising a whole vehicle controller used for sending a brake signal to an EMB control module through a first communication network or sending the brake signal to a redundancy control module through a second communication network; the fault detection module is used for detecting whether the EMB control module has a fault or not in real time; the redundancy control module is used for acquiring a wheel speed signal of each wheel and calculating braking torque data of a left rear wheel and braking torque data of a right rear wheel based on the braking signal and the wheel speed signal of each wheel; the left rear wheel end actuator applies a braking torque corresponding to the braking torque data of the left rear wheel to the left rear wheel; and the right rear wheel end executor applies the braking torque corresponding to the braking torque data of the right rear wheel to the right rear wheel.
