The invention discloses a networked vehicle cooperative collision avoidance early warning system and method in a signal-control-free intersection environment, and the system obtains the information of vehicles in a radiation range and a vertical lane thereof through a vehicle-to-vehicle communication technology, shares the information of the vehicles, and takes the time when the vehicles arrive at an intersection at the same time as the vehicle-to-vehicle pre-judgment information. If the absolute value of the time difference of the two vehicles arriving at the same intersection is smaller than a set threshold value, and the ratio of the distance between the vehicles and the intersection to the calculated safe distance is smaller than 1.6, the man-machine interaction module gives an early warning to a driver. According to the invention, other vehicles in the surrounding environment can be sensed, so that whether collision occurs can be judged according to the driving state. A driver can take corresponding measures according to the prompt of the collision avoidance early warning system so as to avoid collision, the cooperative intersection collision early warning realized by using the vehicle-vehicle communication technology can effectively reduce the occurrence of collision accidents at the non-signal-control intersection, and the road traffic safety is improved.
本发明公开了一种无信控交叉口环境下网联车辆协作避碰预警系统及方法,通过车车通信技术,获取车辆在其辐射范围内与其垂直车道车辆的信息并共享自身车辆信息,以同时到达一个交叉路口的时间作为辆车预判信息,若到达同一路口的两辆车辆时间差绝对值小于设定阈值,且车辆距离交叉口的距离与计算出的安全距离的比值小于1.6时,人机交互模块对驾驶员进行预警,本申请能够感知到周围环境中的其他车辆,从而根据行驶状态判断是否会发生碰撞,驾驶员可以通过避碰预警系统的提示采取相应的措施,进而避免碰撞,利用车车通信技术实现的协同式交叉路口碰撞预警可以有效降低无信控交叉口碰撞事故的发生,提高道路交通安全。
