The invention discloses a vehicle anti-collision early warning method. The method comprises the following steps: step S10, acquiring multiple groups of monitoring data packets obtained by multiple groups of monitoring equipment mounted on a vehicle in real time; step S11, according to the identification numbers of the radar device and the camera in each group of monitoring data packets, determining the position direction corresponding to the corresponding distance data and the environment image; step S12, analyzing distance data in two adjacent unit time in the monitoring data packet in each position direction, and forming an influence factor set in each position direction; step S13, inputting the corresponding information in the multiple groups of monitoring data packets and each influence factor set into a pre-established cellular automaton model, and predicting whether there is a collision risk in each position direction; and step S14, giving an early warning to a driver to prompt the collision risk. The invention further provides a corresponding system and a vehicle. According to the invention, the collision risk of the vehicle in each direction in the driving process can be predicted based on the cellular automaton model; the prediction capability of vehicle pre-collision is improved, and a more accurate collision prediction result can be obtained.

    本发明公开了一种车辆防碰撞预警方法,包括步骤:步骤S10,实时获取安装于车辆上的多组监测设备所获得的多组监测数据包;步骤S11,根据每组监测数据包中的雷达装置及摄像头的标识号,确定相应距离数据和环境图像所对应位置方向;步骤S12,对各位置方向上监测数据包中相邻两个单位时间内距离数据进行分析,并形成各位置方向上的影响因子集;步骤S13,将多组监测数据包中的相应信息以及各影响因子集输入一预先建立的元胞自动机模型,对各位置方向上是否存在碰撞风险进行预测;步骤S14,向驾驶员进行预警提示所述碰撞风险。本发明还提供相应的系统及车辆。实施本发明,可以基于元胞自动机模型预测车辆在行驶过程中各方向上存在的碰撞风险;提高了车辆预碰撞的预测能力,并能获得更加精准的碰撞预测结果。
