The invention belongs to the technical field of automobiles, and discloses a vehicle curve collision early warning method, device and equipment and a storage medium. The method comprises the following steps: acquiring a relative distance between a vehicle and a target vehicle and a current driving parameter of the vehicle; the current driving parameters are analyzed, and the turning radius of the vehicle is obtained; the turning radius of the target vehicle is obtained according to the relative position relation and the relative distance between the target vehicle and the vehicle; comparing the turning radius of the vehicle with the turning radius of the target vehicle, and performing curve collision early warning according to a comparison result; the relative position of the vehicle and the target vehicle in the curve is judged according to the turning radius of the vehicle and the turning radius of the target vehicle, so that the alarm function is more accurate, the driving safety in the curve is ensured, the false alarm and missing alarm of forward and backward collision early warning are reduced, and the situation that the vehicle is overtaken or overtaken during high-speed driving is avoided. The collision early warning function misjudges front and rear vehicles, the trust degree of a driver on the collision early warning function is affected, and the comfort of the system is reduced.
本发明属于汽车技术领域,公开了一种车辆弯道碰撞预警方法、装置、设备及存储介质;该方法包括:获取自车与目标车辆的相对距离以及自车的当前驾驶参数;对当前驾驶参数进行分析,得到自车转弯半径;根据目标车辆与自车的相对位置关系以及相对距离得到目标车辆的转弯半径;比较自车转弯半径和目标车辆的转弯半径,根据比较结果进行弯道碰撞预警;本发明通过自车转弯半径和目标车辆转弯半径判断弯道内自车与目标车辆的相对位置,使得报警类功能更加准确,确保弯道内的行驶安全,减少前向和后向碰撞预警的误报和漏报,避免在高速行驶超车或被超车时,碰撞预警功能对前后方车辆产生误判,影响驾驶员对碰撞预警功能的信任度和降低系统舒适性的问题。
