The invention discloses an energy-saving vehicle speed planning method and system, electronic equipment and a storage medium. The method comprises the steps that the current speed and the current acceleration of a vehicle are obtained; acquiring gradient information and spacing information of a plurality of sub-road sections in a driving target road section in front of the vehicle, wherein each sub-road section has a unique gradient; on the basis of the current speed, the current acceleration, the gradient information and the distance information, the predicted speed and predicted driving time of the vehicle in each sub-road section under the condition that the power output of the vehicle is not changed are calculated; calculating a predicted average speed of the driving target road section, and calculating a speed difference value between the predicted average speed and a target speed of passing through the driving target road section; and generating a first planned speed of the vehicle in each sub-road section based on the speed difference value and the predicted speed of the vehicle. And the speed planning calculation efficiency of the driving target road section is high.

    一种节能型车辆速度规划方法、系统、电子设备、存储介质,所述方法包括:获取车辆的当前速度和当前加速度;获取所述车辆前方的行驶目标路段中的多个子路段的坡度信息和间距信息,每个子路段内具有唯一坡度;基于所述当前速度、所述当前加速度、所述坡度信息、所述间距信息,计算出所述车辆在动力输出不变的情况下每个所述子路段内的车辆预测速度和预测行驶时间;计算出所述行驶目标路段的预测平均速度,并计算出所述预测平均速度和通过所述行驶目标路段的目标速度之间的速度差值;基于所述速度差值和所述车辆预测速度,生成车辆在每个所述子路段的第一规划速度。对行驶目标路段的速度规划计算效率高。
