Response Analysis and Handlmg Safety Evaluationfor Driver/Vehicle/Road Closed-loop ManeuveringSystem with Random Road Input

本文建立了一种平衡随机道路输入的数学模型。应用精细积分法,进行了具有此类随机道路输入的人-车-路闭环操纵系统响应的仿真研究与汽车的主动安全性评价。该方法不仅为精确算法,而且可以缩短汽车主动安全性的评价周期,避免实车试验带来的巨大的经济负担。结合实例,说明该方法是正确的,其结果是有效而合理的。

A kind of mathematical model for steady random road input is built in this paper. The response simulation is studied and the vehicle active safety is evaluated using finer integration method. This method not only is precise, but also can shorten the evaluation period of active safety and reduce the tremendous cost for real vehicle testing. A practical example shows the correctness and efficiency of the method.
