摘　　要：大型车辆的交通事故已经成为社会关注的热点问题,减少碰撞风险是交通安全研究的重要内容。根据大型车辆前向碰撞预警、后方碰撞预警和侧向防撞预警的要求,设计了一种全方位防撞预警系统。系统以分布式信息采集、处理和报警平台为基础,通过基于安全距离的算法实现分级预警。实车预警实验表明该系统能够根据安全等级准确地给出报警信息。As large vehicle traffic accidents have become a hot spot,it is an important content of road safety research to reduce the collision risk.According to the needs of forward collision warning,rear impact warning and lateral collision warning of large vehicle,a comprehensive anti-collision warning system is presented in this paper.The system is constructed on the distributed information acquisition,processing and warning platform.Different warnings are realized through the algorithms based on security distance algorithm.The real vehicle warning experiments show that the system can give accurate alarm information based on levels of security.
