摘　　要：随着我国经济迅速发展,公路基础设施也得以逐步完善,中国公路运输业高速发展。客运车辆的行驶安全成为当下汽车领域研究的又一新的热点和难点。客运车辆纵向避撞预警系统是客运车辆主动安全辅助系统中较为重要的组成部分,其可以及时辨别客运车辆行驶状态,计算与前方行驶客运车辆的安全距离,并及时对客运车辆驾驶员进行预警。从而达到减少客运车辆发生事故的概率。文章围绕客运车辆纵向避撞系统相关研究,对客运车辆纵向行驶安全域进行建模分析,通过分析比较前后车的不同行驶状态及不同的天气条件和路面条件,进行不同的纵向安全域模型计算,得到不同状态下的客运车辆纵向行驶的安全域。With the rapid development of China’s economy, highway infrastructure has been gradually improved, China’s highway transport industry has developed rapidly. The driving safety of vehicles has become a new hot and difficult point in the field of automobile research nowadays. Longitudinal Collision avoidance warning System of passenger vehicle is an important part of vehicle active safety auxiliary system. It can identify the driving state of the vehicle in time, calculate the safe distance with the driving vehicle ahead, and make early warning to the vehicle driver. So as to reduce the probability of accidents in passenger vehicles. In this paper, the longitudinal collision Avoidance system of passenger vehicle is studied, and the longitudinal driving safety area of passenger vehicle is modeled and analyzed. By analyzing and comparing the different driving states and different weather conditions and road conditions of the front and rear cars, the longitudinal safety domain model is calculated and the safety area of the passenger vehicles under different conditions is obtained.
