摘要
为了提高在高速行驶状态下的车辆主动安全性能,并针对高速公路上汽车追尾事故发生的特点,以汽车制动过程为分析基础,得到3种不同的安全车距计算方法.利用Matlab对干燥路面状况下的车速与安全车距的关系进行仿真.仿真结果表明,其符合国家对机动车运行安全的要求.在此基础上,研究了汽车防追尾安全行驶的控制与执行,最后提出了基于不同影响因子的安全车距等级预警方法.
To improve initiative security of vehicle at high speed, according to the characteristics of the accident of highway vehicle, three different safe vehicle gap can be obtained on the basis of the analysis of a vehicle braking process. It can be emulated by using matlab so as to understand fully the relationship between vehicle speed and safe gap at dry road conditions. The simulation results show that the safe running requirement of the vehicle can be acquired. And then the process of the control and implementation of safe running was investigated. Finally the method of warning of safe vehicle gap was advanced based on the level of security of the proposed factor.
