The invention provides a vehicle intersection collision early warning method and system based on GPS and V2X communication, and relates to the technical field of 5G-CV2X communication and vehicle early warning, and the method comprises the steps: building the connection between a main vehicle and surrounding vehicles through a V2X communication mode; the method comprises the following steps that: a main vehicle acquires GPS information of surrounding lateral driving vehicles and GPS information of the main vehicle, and pre-processes the GPS information; vehicle speeds, course angles and time data in the preprocessed GPS information of all vehicles are extracted; the intersection point of the driving direction of the main vehicle and the driving direction of the lateral driving vehicle and the vector time when the two vehicles arrive at the intersection point are preset, whether the positions of the two vehicles coincide at the intersection or not is predicted and judged according to a time simulation judgment algorithm, and therefore whether the two vehicles collide or not is judged, and early warning information is found in time.

    本公开提供了基于GPS和V2X通信的车辆交叉路口碰撞预警方法及系统,涉及5G‑CV2X通信及车辆预警技术领域,包括:通过V2X通信方式建立主车与周围车辆之间的连接;主车获取周围侧向行驶车辆的GPS信息以及自身的GPS信息,并对GPS信息进行预处理;提取预处理后所有车辆的GPS信息中的车辆速度、航向角以及时间数据;预设主车和侧向行驶车辆的行驶方向的交点以及两车到达交点经过的矢量时间,根据时间模拟判断算法,预测和判断两车在交叉路口是否存在位置重合的情况,以此判断两车是否发生碰撞,并及时发现预警信息。
