基于故障树分析的汽车防盗系统故障诊断研究

应用故障树分析法对汽车防盗系统不解除故障进行研究,建立了模块不工作、钥匙不工作、线路故障和启动装置按钮不工作的故障树模型。以迈腾B8装备的第五代防盗系统故障为例,进行故障分析和排查,结果表明该方法能够快速查找分析故障原因,提高效率,可为汽车防盗系统的故障诊断提供参考依据。

Research on Fault Diagnosis of Automobile Anti-theft System Based on Fault Tree Analysis

The fault tree analysis is applied to study the failure of the automobile anti-theft system without removing,and the fault tree models for the module does not work,the key does not work,the car circuits fault and the starting device button does not work are established.Taking the fault of Magotan B8 with the fifth generation anti-theft system as an example,fault analysis and troubleshooting are carried out.The results show that this method can quickly find and analyze the cause of the fault,improve the efficiency,and provide reference for the fault diagnosis of automobile anti-theft system.
