The invention relates to a curve road section early warning method and device, electronic equipment and a storage medium. The curve road section early warning method comprises the steps that path point information on a current reference path of a vehicle is acquired; calculating a target curvature radius corresponding to each piece of path point information; and under the condition that any target curvature radius is smaller than a first threshold value, calculating the average curvature radius of the reference path. According to the method, the target curvature radius corresponding to each piece of path point information on the reference path of the vehicle can be calculated, under the condition that any target curvature radius is smaller than a first threshold value, the current reference path can be regarded as a curve road section, the average curvature radius of the curve road section is calculated, and if the average curvature radius is smaller than a second threshold value, the current reference path is regarded as the curve road section. If yes, it is determined that the reference path comprises the sharp turn road section, so that the sharp turn scene can be judged in advance, safety early warning information is output when the driving time is smaller than the safety time interval, a driver is reminded, and the driving safety is improved.

    本申请涉及一种弯道路段预警方法、装置、电子设备及存储介质,包括:获取车辆当前的参考路径上的路径点信息;计算每个路径点信息对应的目标曲率半径;在任意一个目标曲率半径小于第一阈值的情况下,计算参考路径的平均曲率半径。该方法,可计算车辆的参考路径上每个路径点信息对应的目标曲率半径,在任意一个目标曲率半径小于第一阈值的情况下,可认为当前的参考路径为弯道路段,计算该弯道路段的平均曲率半径,若平均曲率半径小于第二阈值,则确定该参考路径中包括急弯路段,从而可以提前判断急弯场景,并且,在行驶时间小于安全时距时输出安全预警信息,对驾驶员进行提醒,提高了驾驶的安全性。
