摘要
应用故障树分析方法对车道偏离预警系统的可靠性进行了研究,简要介绍了故障树分析的基本理论以及车道偏离预警系统的工作原理,建立了以车道偏离未报警为顶事件的故障树,给出了车道偏离未报警的各种原因及其组合方式,采用下行法对车道偏离预警系统故障进行了定性分析和定量计算,确定了系统的薄弱环节以及故障维修的顺序。
The reliability of a lane departure warning system was investigated based on the fault tree analysis. The theory of fault tree analysis and the operating principle of lane departure warning system were briefly introduced. The fault tree that the top event fault was lane departure without warning was established and all kinds of possible reasons and their combined forms of lane departure without warning were found out. Qualitative analysis and quantitative calculation of fault tree were presented by the descending method ; the weakness of system and the order of breakdown maintenance were confirmed.
