The invention relates to a braking system and a design method thereof. Comprising a double-control EPB system. The double-control EPB system comprises a first EPB, a second EPB, a third EPB and a fourth EPB; the first EPB and the second EPB are installed on a left front wheel and a right front wheel of the vehicle respectively. The third EPB and the fourth EPB are respectively mounted on a left rear wheel and a right rear wheel of the vehicle; an A1 actuator is arranged on the first EPB; an A2 actuator is arranged on the fourth EPB; a B1 actuator is arranged on the second EPB; a B2 actuator is arranged on the third EPB; the actuator A1 and the actuator A2 are controlled by the controller M1; the actuator B1 and the actuator B2 are controlled by the controller M2; a double-control EPB redundant braking scheme is designed, hazard analysis and risk assessment are carried out according to a function failure mode from function definition, a function safety target is exported and finally converted into a function safety mechanism and measure of an executable level, meanwhile, development economy and whole vehicle safety are improved, the problems of braking safety and regulation compliance are solved, and the method is suitable for popularization and application. The enterprise cost is reduced.

    本发明是一种制动系统及其设计方法。包括双控EPB系统;双控EPB系统包括第一EPB、第二EPB、第三EPB和第四EPB;第一EPB、第二EPB分别安装在车辆的左前轮和右前轮上;第三EPB和第四EPB分别安装在车辆的左后轮和右后轮上;第一EPB上设置有A1执行器;第四EPB上设置有A2执行器;第二EPB上设置有B1执行器;第三EPB上设置有B2执行器;A1执行器和A2执行器由M1控制器控制;B1执行器和B2执行器由M2控制器控制;本发明设计双控EPB冗余制动方案,从功能定义出发,根据功能失效模式进行危害分析与风险评估,导出功能安全目标,最后转化为可执行层面的功能安全机制及措施,同时提升开发经济性、整车安全性,并解决了制动安全及法规合规问题,降低企业成本。
