The embodiment of the invention provides a vehicle speed planning method and device, electronic equipment and a storage medium. The method comprises the steps that a vehicle planning decision label corresponding to a target vehicle is determined according to collected surrounding information; determining target ST reference lines of target vehicles corresponding to different vehicle planning decision labels; smoothing the target ST reference line to generate a smooth ST reference line; and deriving the smooth ST reference line, and outputting a target speed planning curve. The method comprises the following steps: determining a planning decision label of a target vehicle by collecting surrounding information, generating a target ST reference line based on different labels, and finally outputting an optimal speed and acceleration curve through smooth processing and quadratic programming algorithm optimization. The method not only improves the decision precision and response speed of the intelligent driving system, but also enhances the stability and safety of the system, so that the vehicle can perform speed control more intelligently and efficiently in different driving scenes.

    本发明实施例提供了一种车辆速度规划方法、装置、电子设备及存储介质,包括:采集的周边信息确定目标车辆对应的车辆规划决策标签;确定不同车辆规划决策标签对应的目标车辆的目标ST参考线;对目标ST参考线进行平滑处理,生成平滑ST参考线;对平滑ST参考线求导,输出目标速度规划曲线。即通过采集周边信息确定目标车辆的规划决策标签,并基于不同标签生成目标ST参考线,再通过平滑处理和二次规划算法优化,最终输出最优的速度和加速度曲线。这种方法不仅提高了智能驾驶系统的决策精度和响应速度,还增强了系统的稳定性和安全性,使得车辆在不同驾驶场景下能够更加智能、高效地进行速度控制。
