摘　　要：为提高城市环境中车辆驾驶的安全性,设计了一种主动安全避碰系统.该系统底层硬件采用分布式架构,底层软件采用uC/OS-Ⅱ嵌入式实时操作系统,通信系统采用CANopen通信协议.针对城市环境道路曲率变化大的情况,提出了一种基于激光雷达的随动预警区域检测方法.实际实验证明了系统的稳定性和检测方法的有效性.To improve vehicle driving safety in urban environment,an active safety collision avoidance system was presented and implemented.A distributed architecture was adopted in the low-level system,uC/OS-II employed as the real-time operational system of the bottom software.The communication system was realized by CANopen protocol.Since the road curvature always changes drastically in urban environment,an adaptive warning area based collision detecting method was proposed using scanning laser radar.The stability of the system and the validity of the proposed method were proved by the real experiments.
