进行了具有平稳随机道路输入的驾驶员—汽车闭环系统的响应分析与操纵安全性评价 ,该算法不仅为精确算法 ,而且可以缩短评价周期 ,并且减少实车试验带来的巨大经济负担。在此基础上 ,研究了演变随机道路输入的驾驶员—汽车闭环系统的响应分析与操纵安全性评价 ,该项研究涉及汽车速度随时间慢变的情况 ,因此能够更好地评价汽车真实的行驶过程 The response analysis and steering safety evaluation of the driver-car closed-loop system with smooth and stochastic road input are carried out. The algorithm not only is an accurate algorithm, but also can shorten the evaluation cycle and reduce the huge financial burden caused by the actual vehicle test. On this basis, the response analysis and steering safety evaluation of the driver-car closed-loop system evolving stochastic road input are studied. The research involves the case that the vehicle speed changes slowly with time, so that the real driving of the car can be better evaluated process
