The invention provides a multifunctional shuttle valve type dual-motor redundancy braking system and a control method thereof. The braking system mainly comprises a brake pedal assembly, a main electro-hydraulic servo brake assembly, an auxiliary electro-hydraulic servo brake assembly, a shuttle valve, a hydraulic control unit and a brake set. Wherein the main electro-hydraulic servo brake assembly is connected with the brake pedal, and the main electro-hydraulic servo brake assembly and the auxiliary electro-hydraulic servo brake assembly are in communication connection. A front cavity of a main brake master cylinder is directly connected to one oil inlet of the hydraulic control unit through a first loop, a rear cavity of the main brake master cylinder and an auxiliary brake master cylinder are connected to two oil inlets of the shuttle valve through a second loop and a third loop respectively, and an oil outlet of the shuttle valve is connected with the other oil inlet of the hydraulic control unit through a fourth loop. The hydraulic control unit is connected to the brake set through a brake pipeline. The system can meet the requirement of servo braking of vehicles with high design tonnage, and has the advantages of being compact in structure, convenient to arrange, optimal in braking pressure distribution and the like.
