The invention discloses a collision early warning system which is used for improving the accuracy of vehicle collision risk prediction. A target vehicle pair is screened out according to a preset screening condition; for each target vehicle pair, determining a collision time set of the target vehicle pair based on the current position information of each vehicle in the target vehicle pair; determining whether the vehicles in the target vehicle pair will collide or not based on the collision time set; and if the collision is determined to occur, sending an alarm instruction to the vehicle in the target vehicle. Before collision early warning is carried out on the vehicles, the vehicles are screened according to the preset screening condition, whether the vehicles meet the triggering condition or not is judged firstly, waste of computing resources caused by anti-collision early warning on all the vehicles is avoided, whether the vehicles will collide or not is determined according to the current position information of the vehicles, and the vehicle collision early warning efficiency is improved. The high-precision map information and the information reported by the vehicle are fully combined, so that the early warning of the vehicle is more accurate.
本申请公开了一种碰撞预警系统,用于提高对车辆碰撞风险预测的准确性。本申请根据预设筛选条件筛选出目标车辆对;针对每个目标车辆对:基于目标车辆对中每个车辆的当前位置信息确定目标车辆对的碰撞时间集合;基于碰撞时间集合确定目标车辆对中的车辆是否会发生碰撞;若确定会发生碰撞,则向目标车辆对中的车辆发出告警指示。在对车辆进行碰撞预警之前,通过预设筛选条件对车辆进行筛选,先判断车辆是否满足触发条件,避免了对所有车辆进行防碰撞预警导致的对计算资源的浪费,通过车辆的当前位置信息来确定车辆是否会发生碰撞,充分结合了高精地图信息以及车辆上报的信息,使得对车辆的预警更加的准确。
