摘　　要：以车车之间的纵向防碰撞系统作为研究对象,提出了基于车联网的防碰撞系统架构及软硬件实现方式,建立了车-车、车-路之间的车联网,建立了基于车联网的安全距离计算模型,采用模糊PID控制算法保证车辆精确地避免碰撞,使得车辆及时地、精确地减速行驶,防止车辆纵向碰撞事故的发生。In the paper,the anti-collision system between vehicles longitudinal direction is taken as the focus of thestudy. The architecture of anti-collision system and the realization of hardware and software is put forward. The internet ofvehicles between V2V and V2I is established,the safety distance calculation model of the network is adopted,and thefuzzy PID control algorithm is used in the system to ensure that the vehicle avoids the collision accurately,so that thevehicle can decelerate in time and accurately to prevent the longitudinal collision of the vehicle.
