| 摘 要： | 为分析车辆运行状态对行车安全的影响,提出了基于事故树分析的车辆安全状态模糊综合评价方法。在系统分析车辆安全状态影响因素的基础上,构建了车辆安全状态事故树,通过计算事故树基本事件的结构重要度明确车辆安全状态的主要影响因素。根据车辆安全状态事故树分析结果,选取车载质量、车速、横向安全车距等9个因素作为车辆安全状态评价的主要关联因子,基于模糊评判理论构建了车辆安全状态模糊综合评价模型。在CA1046L2轻型载货汽车上安装车辆监测预警系统,系统自动采集车辆行驶过程中的运行状态参数,采用预设故障的试验方法进行了道路试验,利用评价模型对车辆的安全状态进行分析评价。试验结果表明,该模型应用于车辆安全状态评价具有较高的适用性。

| Abstract: | In order to analysis the impact of vehicle condition on its safety states,a fuzzy comprehensive assessment method was put forward on the basis of fault tree analysis.The fault tree of vehicle safety states was established on the basis of scientific analysis of influencing factors of vehicle safety states.The sorting of structure importance of all the basic events was obtained by calculating the structure importance.Based on the fault tree analysis result of vehicle safety states,nine key elements,namely loa... |
