驾驶人应急转向操作行为下的车辆横向响应

Vehicle lateral response under driver's emergency steering operation behavior

为了深入研究驾驶人应急转向操作行为下车辆的横向响应状态,在车辆受力分析的基础上,建立了车辆应急转向响应力学模型。通过驾驶人应急转向行为下车辆横向应急响应实车试验,采集了驾驶人应急转向操作力度与车辆横向响应等关键数据,对比分析了实车试验数据与模型计算数据。试验结果表明:所建立的模型计算得到的数据误差较小,相对误差均在10%以内,能够反应驾驶人事故前应急操作,可用于道路交通事故再现的研究。

In order to study vehicle lateral response under driver＇s emergency steering operation behavior, vehicle emergency steering response dynamic model is established for reverse calculation based on vehicle dynamic analysis, and driver emergency steering operating vehicle emergency response to a real vehicle test is designed. During the tests, driver emergency steering force and vehicle emergency response level data operation are collected and thus real vehicle test data and dynamic model calculated val- ues are analyzed. The research results show that the discrepancy of proposed model is very small, while the emergency response model error rate is within 10%. Therefore, this research is conductive to study the operation before emergency, and helpful to the study of accident reconstruction.
