Abstract: 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.

Key words: active safety, collision-avoidance system, adaptive warning area, CANopen protocol
