From the vehicle safety angle , it provides theory and technical support for the research on automatic drive , intelligent drive and traffic safety . this paper is based on the study of single car external flow field about the simulation on the ground boundary layer , the rotating wheels and the crossing wind load , and on the two cars running - in - row and overtaking maneuvers 同时使用稳态超车的研究方法,利用了阶背式、快背式和厢式mira模型代替轿车模型进行了不同车型超车过程的对比研究,利用定性和定量两种方法研究了不同轿车车型在超车过程中的异同。
And the development of intelligent transportation system ( its ) and intelligent vehicle ( iv ) is one effective measure to solve the traffic safety problem of our country , thus various research has been done on vehicle intelligent auxiliary drive system and automatic drive system , of them one of key problems is how to obtain the dynamic distance between two vehicles 发展智能交通系统与智能车辆是解决我国交通安全问题的有效措施。由此,开展了各种辅助驾驶系统和自动驾驶系统的研究,其中,动态下两车间距的测量是一个关键问题。
