The embodiment of the invention discloses a vehicle early warning method and device, equipment, a medium and a product. The vehicle early warning method comprises the steps that basic safety message data BSM, map message data MAP and road side information data RSI are acquired; the main vehicle is a vehicle needing early warning; determining whether a collision point exists according to the driving tracks of the main vehicle and the remote vehicle; when the collision point exists, if the main vehicle and the far vehicle are located on the same lane, the vehicle distance between the main vehicle and the far vehicle is calculated according to the data of the road reference coordinate system; if the main vehicle and the far vehicle belong to different lanes, calculating the vehicle distance between the main vehicle and the far vehicle according to the driving coordinates of the track of the main vehicle moving to the collision point; determining an earliest early warning moment and a latest early warning moment according to the vehicle distance, and determining an early warning range according to the earliest early warning moment and the latest early warning moment; if the driving time of the main vehicle belongs to the early warning range, early warning is given out, early warning of the vehicle based on the log data is achieved, the calculation process of the early warning time is more concise, and the accuracy of the early warning time is improved.

    本公开实施例公开了一种车辆预警方法、装置、设备、介质及产品,包括:获取基础安全消息数据BSM、地图消息数据MAP和路侧信息数据RSI;主车为需要预警的车辆;根据主车和远车的行驶轨迹确定是否存在碰撞点;存在碰撞点时,若主车和远车位于同一个车道,则根据道路参考坐标系数据计算主车和远车的车辆间距;若主车与远车属于不同车道,则根据主车移动至碰撞点的轨迹的行驶坐标计算主车和远车的车辆间距;根据车辆间距确定最早预警时刻和最晚预警时刻,根据最早预警时刻和最晚预警时刻确定预警范围;若主车的行驶时间属于预警范围,发出预警,实现了基于日志数据对车辆进行预警,使得预警时间的计算过程更加简洁,提高了预警时间的准确性。
