The embodiment of the invention discloses a vehicle speed planning method and device, electronic equipment and a storage medium. The method comprises the steps that state data of a driving vehicle are acquired, sampling data are obtained through sampling based on the state data, a preset sampling interval and a preset sampling number, and the sampling data comprise a future time point and the vehicle speed of the driving vehicle at the future time point; generating at least one piece of alternative speed curve data according to the sampling data and the state data; respectively determining acceleration information of the at least one piece of alternative speed curve data, and updating the at least one piece of alternative speed curve data according to the acceleration information; and determining target speed curve data from the at least one piece of alternative speed curve data so as to complete speed planning of the driving vehicle according to the target speed curve data. According to the technical scheme of the embodiment of the invention, the calculation power required by vehicle speed planning is reduced, and the driving safety of the driving vehicle is ensured.
