The invention provides a vehicle collision early warning method. The method comprises the following steps: acquiring first position information and driving state information of a vehicle; acquiring obstacle position information; predicting a vehicle driving track based on the first position information and the driving state information to obtain vehicle track points at a plurality of future time points; constructing a vertical shaft alignment bounding box according to the vehicle track points and the vehicle body size information; establishing a directed bounding box according to the vehicle track point, the vehicle body size information and the vehicle state information; vehicle collision detection is carried out according to the axis alignment bounding box, the directed bounding box and the obstacle position information; when it is detected that the vehicle collides with the obstacle, the vehicle is controlled to execute the early warning action, the accuracy of collision prediction can be improved, and accurate early warning is achieved.
本申请提供了一种车辆碰撞预警方法,所述方法包括:获取车辆的第一位置信息和行驶状态信息;获取障碍物位置信息;基于所述第一位置信息和所述行驶状态信息对车辆行驶轨迹进行预测得到多个未来时间点下的车辆轨迹点;根据所述车辆轨迹点和车身尺寸信息构建立轴对齐包围盒;根据所述车辆轨迹点、车身尺寸信息、车辆状态信息建立有向包围盒;根据所述轴对齐包围盒、所述有向包围盒和所述障碍物位置信息进行车辆碰撞检测;在检测到车辆与障碍物发生碰撞时,控制车辆执行预警动作,可提升了碰撞预测的精准度,实现精准预警。
