The invention discloses an auxiliary braking system and method of a vehicle. The auxiliary braking system comprises a first controller, a first power assisting assembly and a second power assisting assembly, and the output end of the first power assisting assembly and the output end of the second power assisting assembly are both connected with a braking pipeline of a booster; the first power assisting assembly comprises a first pressure sensor, and the first controller is in signal connection with the first pressure sensor; the second power assisting assembly comprises a second controller, the second controller is in signal connection with a second pressure sensor of the pedal, and the second controller is in signal connection with the first controller. According to the booster, the second boosting assembly is arranged on the braking pipeline of the booster and serves as a supplementing pipeline of the original first boosting assembly, braking boosting can be supplemented when a vacuum pump/compressor of the first boosting assembly is damaged or vacuum/air pressure of a loop is insufficient, the braking safety and reliability are improved, and practicability is high.

    本申请公开了一种车辆的辅助制动系统及辅助制动方法,辅助制动系统包括第一控制器、第一助力组件和第二助力组件,第一助力组件和第二助力组件的输出端均与助力器的制动管路连接;第一助力组件包括第一压力传感器,第一控制器与第一压力传感器信号连接;第二助力组件包括第二控制器,第二控制器与踏板的第二压力传感器信号连接,并且第二控制器与第一控制器信号连接。本申请通过在助力器的制动管路上设置第二助力组件,作为原有第一助力组件的补充管路,能够在第一助力组件的真空泵/压缩机损坏或者回路的真空/气压不足时提供制动助力的补充,提高制动的安全性和可靠性,实用性较高。
