The invention provides a vehicle speed control method, device and equipment and a storage medium. The method can be applied to the field of unmanned driving. The method comprises the following steps of obtaining a driving path of a vehicle on a high-precision map and a speed set corresponding to each path point on the driving path, and according to the speed set corresponding to each path point, calculating the speed of the vehicle according to the speed set corresponding to each path point; and determining a speed limit value of each path point, and controlling the running speed of the vehicle according to the speed limit value of each path; wherein the speed set corresponding to each path point comprises a speed limit value related to at least one map element and the maximum driving speed value of the vehicle. The method is advantaged in that a speed limit value of each path point is determined based on multiple information on the high-precision map, so the speed limit requirements of various road conditions can be well met, and the vehicle speed can be accurately controlled.
本申请提供一种车速控制方法、装置、设备及存储介质,该方法可应用于无人驾驶领域,该方法包括:获取车辆在高精度地图上的行驶路径,以及行驶路径上每个路径点对应的速度集合,根据每个路径点对应的速度集合,确定每个路径点的限速值,根据每个路径的限速值控制车辆的行驶速度。其中,每个路径点对应的速度集合包括与至少一个地图元素相关的限速值以及车辆的最大行驶速度值。由于各路径点的限速值是基于高精度地图上的多重信息确定的,可较好适应各种路况限速需求,从而实现对车辆速度的精准控制。
