The embodiment of the invention provides a collision early warning method, a vehicle-mounted terminal and a storage medium, and belongs to the field of intelligent automobiles. The method comprises the following steps: acquiring a map message MAP, state information of a main vehicle and basic security messages BSM of a plurality of remote vehicles; according to the MAP and the state information, determining whether the main vehicle is about to drive into an intersection; if the main vehicle is about to drive into the intersection, according to the MAP, the state information and the BSM of each far vehicle, screening out a target far vehicle having a collision risk with the main vehicle in the intersection from the plurality of far vehicles; in the process from the moment when the main vehicle drives into the intersection to the moment when the main vehicle drives out of the intersection, if it is predicted that the main vehicle collides with the target remote vehicle, collision early warning information is output. According to the scheme, the accuracy of vehicle collision risk detection and the accuracy of early warning are greatly improved.
本发明实施例提供一种碰撞预警方法、车载终端及存储介质,属于智能汽车领域。该方法包括:获取地图消息MAP、主车的状态信息和多个远车的基础安全消息BSM;根据所述MAP和所述状态信息,确定所述主车是否即将驶入交叉路口;若所述主车即将驶入交叉路口,则根据所述MAP、所述状态信息和每个所述远车的BSM,从所述多个远车中筛选出与所述主车在所述交叉路口内存在碰撞风险的目标远车;在所述主车驶入所述交叉路口到所述主车驶出所述交叉路口的过程中,若预测到所述主车与一个所述目标远车发生碰撞,则输出碰撞预警信息。本方案极大地提高车辆碰撞风险检测的准确性和预警的准确性。
