The embodiment of the invention provides a vehicle collision early warning method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining second vectors of surrounding vehicles based on vehicle coordinates of the surrounding vehicles; based on the first vector of the current vehicle and the second vector of the surrounding vehicle, obtaining a heading included angle of the driving direction of the current vehicle relative to the surrounding vehicle; obtaining a transverse distance and a longitudinal distance between the surrounding vehicles and the current vehicle based on the course included angle and the vehicle coordinates of the surrounding vehicles; and performing collision early warning on the current vehicle based on the transverse distance and the longitudinal distance. When the course included angle, the transverse distance and the longitudinal distance between the current vehicle and the surrounding vehicles are calculated, only the first vector of the driving direction of the current vehicle in the vehicle coordinate system established by the current vehicle and the positions of the surrounding vehicles of the current vehicle in the vehicle coordinate system are used, so that errors caused by introduction of a large number of physical parameters are avoided; therefore, the result obtained by adopting the scheme of the invention to carry out collision early warning is more accurate.
本申请实施例提供了一种车辆的碰撞预警方法、装置、电子设备及存储介质。方法包括:基于周围车辆的车辆坐标,得到周围车辆的第二向量;基于当前车辆的第一向量、周围车辆的第二向量,获得当前车辆的行驶方向相对于周围车辆的航向夹角;基于航向夹角及周围车辆的车辆坐标,获得周围车辆与当前车辆的横向距离和纵向距离;基于横向距离和纵向距离对当前车辆进行碰撞预警。在计算当前车辆与周围车辆的航向夹角以及横向距离和纵向距离时,仅用到了当前车辆在以其建立的车辆坐标系中的行驶方向的第一向量及该当前车辆的周边车辆在该车辆坐标系中的位置,避免了大量的物理参数的引入导致的误差,因此采用本申请的方案进行碰撞预警得到的结果更准确。
