The invention discloses a vehicle collision avoidance early warning method in a vehicle-road coordination environment. The vehicle collision avoidance early warning method is mainly used for performing vehicle early warning on vehicle lateral collision which is easy to occur in an intersection scene. The influence of the vehicle satellite positioning precision and the communication quality on early warning is comprehensively considered, the vehicle satellite positioning is optimized through a Kalman-Gaussian combined filtering method, and the position of a target vehicle is predicted under the condition of communication packet loss. And the collision probability of the vehicle in the intersection collision area is calculated by considering the minimum safety distance of the positioning error and the communication time delay, so that the aim of early warning is fulfilled. According to the method, the thought of the vehicle collision avoidance early warning method is widened, and a theoretical basis is provided for improvement of the collision avoidance early warning performance of the vehicles in the intersection environment from satellite positioning of the vehicles and communication between the vehicles.

    本发明公开了一种车路协同环境中车辆避撞预警方法,主要针对交叉口场景下易发生的车辆侧向碰撞进行车辆预警。综合考虑车辆卫星定位精度和通信质量对预警造成的影响,通过基于卡尔曼‑高斯的联合滤波方法对车辆卫星定位进行优化,对通信丢包情况下目标车辆进行位置预测,并通过考虑定位误差和通信时延的最小安全距离计算车辆在交叉口碰撞区域的碰撞概率,从而达到预警的目的。本发明拓宽车辆避撞预警方法的思路,是从车辆卫星定位和车辆之间的通信出发,为车辆在交叉口环境下避撞预警性能的提升提供理论基础。
