The invention provides a vehicle collision early warning method and system, and relates to the technical field of vehicles. When the method is executed, the motion state of the vehicle is obtained firstly, the motion state of the vehicle comprises linear motion, fixed curvature motion, variable curvature motion and static state, and when the motion state of the vehicle is the fixed curvature motion or the variable curvature motion, the motion track of the vehicle is predicted according to the time, the arc length and the rotating angle of the fixed curvature motion or the variable curvature motion of the vehicle, the moving trajectory comprises a predicted position coordinate and a moving direction, then predicting the moving trajectory of the target vehicle, and finally performing vehicle collision early warning according to the moving trajectory of the vehicle and the moving trajectory of the target vehicle. In this way, according to the time, the arc length and the rotating angle of the fixed-curvature motion or the variable-curvature motion of the self-vehicle, the running track of the self-vehicle can be accurately predicted, and then vehicle collision early warning can be accurately carried out.

    本申请提供了一种车辆碰撞预警方法及系统,涉及车辆技术领域。在执行所述方法时,先获取自车运动状态,其中,自车运动状态包括直线运动、定曲率运动、变曲率运动以及静止,当自车运动状态为定曲率运动或变曲率运动时,根据自车定曲率运动或变曲率运动的时间、弧长以及转角,预测自车运行轨迹,其中,运行轨迹包括预测位置坐标以及运动方向,再预测目标车辆运行轨迹,最后根据自车运行轨迹和所述目标车辆运行轨迹,进行车辆碰撞预警。这样,根据自车定曲率运动或变曲率运动的时间、弧长以及转角可以对准确地对自车运行轨迹进行预测,进而可以准确地进行车辆碰撞预警。
