摘　　要：交通事故频发使人们对道路交通安全的关注度日益提高,近年来高级辅助驾驶技术逐渐成为汽车行驶安全的研究热点。首先对常用的基于车辆相对位置(CCP)和跨越车道时间(TLC)的车道偏离预警算法进行研究;然后使用Matlab/Simulink设计了一种基于模糊算法的车道偏离预警;接着使用仿真软件Prescan搭建测试环境,即车辆传感器、交通场景、车辆动作等;最后设计联合仿真试验。试验结果表明:设计的基于模糊算法的车道偏离预警达到了设计标准,符合实际需求。The frequent occurrence of traffic accidents has made people pay more and more attention to road traffic safety,and in recent years,advanced assisted driving technology has gradually become a research hotspot of automobile driving safety.Firstly,the commonly used lane departure warning algorithm based on vehicle relative position(CCP)and lane departure warning algorithm based on lane crossing time(TLC)are studied.Then,Matlab/Simulink is used to design a lateral warning algorithm based on fuzzy control.It uses the simulation software Prescan to build a test environment,including vehicle sensors,traffic scenarios,vehicle movements,etc.Finally,a joint simulation experiment is designed.The experimental results show that the horizontal early warning algorithm based on fuzzy control designed meets the design standards and the actual needs.
