The invention provides a vehicle collision early warning processing method and device, and the method comprises the steps: obtaining vehicle information and road network information of a current vehicle and a target vehicle, and carrying out the road network matching of the current vehicle and the target vehicle according to the vehicle information and the road network information; if a road network matching result is that the target vehicle is in front of the current vehicle and is located in the same road section lane, establishing a vehicle body coordinate system of the current vehicle, anddetermining a coordinate set of a predicted trajectory of the current vehicle within a predetermined time; determining that the current vehicle has a collision risk with the target vehicle accordingto a coordinate set of the predicted trajectory of the current vehicle; according to the method, the problem that the way of determining collision risk by calculating the safe vehicle distance betweenthe vehicle and the surrounding adjacent vehicles based on the positioning information of the vehicle in the prior art cannot be suitable for forward collision early warning in a curve scene can be solved, and the method can be well compatible with forward collision scenes of a straight road and a curve.
本发明提供了一种车辆碰撞预警处理方法及装置,该方法包括:分别获取当前车辆与目标车辆的车辆信息和路网信息,并根据该车辆信息和该路网信息对该当前车辆与该目标车辆进行路网匹配;若该路网匹配结果为该目标车辆在该当前车辆前方且处于同一路段车道,建立该当前车辆的车身坐标系,并确定预定时间内该当前车辆的预测轨迹的坐标集合;根据该当前车辆的预测轨迹的坐标集合确定该当前车辆与该目标车辆存在碰撞风险的情况下,发起车辆碰撞预警,可以解决相关技术中基于车辆的定位信息,通过计算自车与周围邻车的安全车距确定碰撞风险无法适用于弯道场景下的前向碰撞预警的问题,能够很好的兼容直道和弯道的前向碰撞场景。
