摘　　要：通过制动助力系统的失效模式分析,提出了对其失效的监测方法,实现了在系统整个工作过程的实时监测.当制动助力系统失效时,一方面能够将失效及时监测出来,另一方面也能进入备用控制模式,从而提高车辆行驶的安全性,降低车辆事故发生的概率.Based on the analysis of potential failure modes of brake booster system, the corresponding failure monitoring method was proposed, and the detection of brake booster system working status in real time was realized. When the failure of brake booster system has occurred ,the system can detect the fault in time and enter into backup control mode as soon as possible, which can improve the safety of the vehicle and reduce the accident probability.
