The invention provides a collision early warning method and system and a storage medium, and the method comprises the steps: constructing a target detection region in an electronic map based on the target vehicle action information of a target vehicle; defining at least one auxiliary vehicle in the target detection area, and determining an auxiliary vehicle blind area for each auxiliary vehicle; roadside sensing data of the blind area of the auxiliary vehicle are collected through roadside sensing equipment; when the roadside sensing data of the blind area contains early warning target action information, calculating a target vehicle action track of the target vehicle, and calculating an early warning target action track of the early warning target; and generating collision early warning information corresponding to the early warning target according to the target vehicle action track and the early warning target action track. Through the roadside sensing devices on the two sides of the road, the global view information of the blind area can be obtained, whether the target vehicle collides with the early warning target or not is effectively predicted, the collision early warning information is sent to remind the target vehicle before collision is predicted, and the target vehicle is helped to avoid collision events in advance.

    本发明提供了一种碰撞预警方法、系统及存储介质,包括:基于目标车辆的目标车辆行动信息,在电子地图中构建目标检测区域;在目标检测区域内定义至少一辆辅助车辆,为每一辆辅助车辆确定辅助车辆盲区;通过路侧感知设备采集辅助车辆盲区的路侧感知数据;当盲区的路侧感知数据包含预警目标行动信息时,计算目标车辆的目标车辆行动轨迹,计算预警目标的预警目标行动轨迹;根据目标车辆行动轨迹和预警目标行动轨迹生成对应于预警目标的碰撞预警信息。通过道路两侧的路侧感知设备,可获取盲区的全局视野信息,有效预测目标车辆与预警目标是否发生碰撞,在预测发生碰撞之前发送碰撞预警信息提醒目标车辆,帮助目标车辆提前规避碰撞事件的发生。
