The invention discloses a vehicle safety distance early warning method and system, a vehicle and a storage medium. The method comprises the following steps: detecting distance information between theside face of the vehicle and an obstacle; establishing a vehicle coordinate system, and determining coordinates of the obstacle under the vehicle coordinate system according to the distance information; converting the coordinates of the obstacle in the vehicle coordinate system into coordinates in a world coordinate system; collecting motion data of the vehicle, and drawing a driving track of thevehicle in a future preset time period in a world coordinate system; calculating the relative distance between the coordinate of the point closest to the obstacle in the driving track of the vehicle and the coordinate of the obstacle, and judging whether the relative distance is smaller than a first distance threshold value or not; and if so, determining that a scratching risk exists. According tothe invention, early warning can be carried out on whether the scratch event occurs between the vehicle and the obstacle in the future preset time period, so that a driver can respond in time and avoid the obstacle in the driving process, and the driving safety is improved.
本发明公开了一种车辆安全距离预警方法、预警系统、汽车及存储介质,其中方法包括:检测车辆的侧面与障碍物之间的距离信息;建立车辆坐标系,并根据距离信息确定障碍物在车辆坐标系下的坐标;将障碍物在车辆坐标系下的坐标转换为在世界坐标系下的坐标;采集车辆的运动数据,并在世界坐标系中绘制未来的预设时段内车辆的行驶轨迹;计算车辆的行驶轨迹中距离所述障碍物最近的点的坐标与障碍物的坐标之间的相对距离,并判断相对距离是否小于第一距离阈值;若是,则确定存在剐蹭风险。本发明能够对未来的预设时段内车辆与障碍物是否会发生剐蹭事件进行预警,从而使得驾驶员能够及时反应并避开行车过程中的障碍物,提高了行车的安全性。
