The invention relates to the technical field of road traffic safety assistance, in particular to an intersection vehicle early warning method and system based on vehicle-road cooperation, and the method comprises the following steps: A, obtaining the position information of a target vehicle and the obstacle information of the position of a target intersection; B, generating corresponding early warning state information according to the obstacle information of the target intersection position; and C, when the distance between the current position of the target vehicle and the position of the target intersection is smaller than or equal to a set early warning distance, continuously sending out a corresponding early warning prompt signal according to the early warning state information. The invention further correspondingly discloses the intersection vehicle early warning system based on vehicle-road cooperation. According to the intersection vehicle early warning method and system, a vehicle driver can be assisted in avoiding visual field blind area position obstacles, and therefore, the probability of traffic accidents of the intersection can be reduced in an assisted mode.

    本发明涉及道路交通安全辅助技术领域,具体涉及一种基于车路协同的交叉路口车辆预警方法及系统,所述方法包括以下步骤:步骤A:获取目标车辆的位置信息,以及目标交叉路口位置的障碍信息;步骤B:根据目标交叉路口位置的障碍信息生成对应的预警状态信息;步骤C:当目标车辆的当前位置与目标交叉路口位置间的距离小于或等于设置的预警距离时,根据预警状态信息持续发出相应的预警提示信号。本发明还相应的公开了一种基于车路协同的交叉路口车辆预警系统。本发明中的交叉路口车辆预警方法及系统能够辅助车辆驾驶者规避视野盲区位置障碍,以能够辅助降低交叉路口的交通事故发生概率。
