The invention aims to provide a brake system with redundancy design and a control method. A master cylinder with a liquid storage tank assembly is separated from an electric control braking system; a hydraulic unit of the electric control braking system is provided with two pressure generating devices; an electric control unit is provided with a double-control ECU; a wheel end electromagnetic valve in the hydraulic unit of the electric control braking system realizes backup redundancy under the control of the double-control ECU; and the main cylinder of the whole system is simple in structure, the power and the torque of the motor are reduced, and the number of the system electromagnetic valves is only 15.
本发明的目的是提供一种冗余设计的制动系统及控制方法,主缸带储液罐总成与电控制动系统分离开;其中电控制动系统的液压单元具备两个压力发生装置;电控单元具备双控ECU;电控制动系统的液压单元中轮端电磁阀在双控ECU控制下实现备份冗余;整个系统主缸结构简单,电机的功率、扭矩下降,系统电磁阀数量只需要15个。
