The invention provides a vehicle speed limiting method. The method comprises the steps of preprocessing a course angle to obtain a corrected course angle, wherein the course angle is an inferior angleand a flat angle between a current driving direction of the vehicle and the north; the course angle is a positive angle along a clockwise direction and is a negative angle along an anticlockwise direction; and there is no jump in the corrected course angle corresponding to a preprocessed driving track point; extracting the corrected course angles corresponding to a first preset number of continuous driving track points; accumulating an absolute value of a difference between the two adjacent corrected course angles in the first preset number of corrected course angles to obtain a road bendingcoefficient; and obtaining a current road speed limit according to a pre-constructed corresponding relation between the road speed limit and the road bending coefficient. By means of the method, the continuous vehicle speed limit value can be obtained, and safety and comfort of the vehicle are guaranteed. The invention further provides a vehicle speed limiting device, electronic equipment and a storage medium.

    本申请提供了一种车辆的限速方法,该方法包括:对航向角进行预处理以得到校正航向角;航向角为车辆当前行驶方向与正北方所夹的劣角和平角;航向角沿顺时针方向为正角度,沿逆时针方向为负角度;预处理后的行驶轨迹点对应的校正航向角中不存在跳变;提取第一预设数目个连续的行驶轨迹点对应的校正航向角;累加第一预设数目个校正航向角中相邻两个校正航向角之差的绝对值,以获取道路弯曲系数;根据预先构造的道路限速与道路弯曲系数的对应关系,获取当前的道路限速。利用本方法能够获取连续的车辆限速值,保证了车辆的安全性与舒适性。本申请还提供了一种车辆的限速装置、电子设备及存储介质。
