2014中国汽车工程学会年会用户论文集：A new vehicle safety system based on the vehicle information system is presented in this paper. The presented system concept includes a distance obstacle detection and safety distance calculation. The system can determine when and how long to record automatically itself by analyzing the relative velocity and the distance between two vehicles. It provides date, pictures and videos of the whole process from Front Collision Warning system(FCW) and Automatic Emergency Braking system(AEB) based on 77G Hz radar, Blind Spot Detection system(BSD) based on 24G Hz radar, and Lane Departure Warning System(LDW) based on camera. The date, pictures and videos provided by systems can facilitate the road accident identification process afterwards. In ever of a traffic accident, the system can store data, pictures and video of the whole event from the active safety system like FCW,BSD and AEB. This stored information can be utilized to facilitate the road.基于车辆主动安全集成信息系统
