The invention provides a global vehicle speed prediction method, a vehicle controller and a readable storage medium. The method comprises the steps of obtaining vehicle networking data of a target vehicle at a current moment; inputting the vehicle networking data into vehicle speed prediction models of different driving styles to respectively obtain predicted vehicle speed sequence data of the target vehicle under different driving styles; according to the predicted vehicle speed sequence data of the target vehicle under each driving style, obtaining predicted vehicle speed data of the target vehicle under each driving style of each fusion period; and for each fusion period, according to the predicted vehicle speed data of the target vehicle in each driving style of the fusion period and the initial weight of the vehicle speed prediction model of each driving style in the fusion period, obtaining predicted fusion vehicle speed data of the target vehicle in the fusion period. The method can globally predict the approximate trend of the vehicle speed in a period of time in the future, and provides necessary reference input for a whole vehicle energy consumption optimization strategy and a power or chassis system control function.

    本发明提供了一种全局车速预测方法、车辆控制器和可读存储介质,该方法包括:获取目标车辆在当前时刻的车辆联网数据;将车辆联网数据输入至不同驾驶风格的车速预测模型中,以分别获取目标车辆在不同驾驶风格下的预测车速序列数据;根据目标车辆在各个驾驶风格下的预测车速序列数据,获取目标车辆在各个融合周期的各个驾驶风格下的预测车速数据;针对每个融合周期,根据目标车辆在该融合周期的各个驾驶风格下的预测车速数据以及各个驾驶风格的车速预测模型在该融合周期的初始权重,获取目标车辆在该融合周期的预测融合车速数据。本发明可以全局预测未来一段时间内车速大致走势,为整车能耗优化策略以及动力或底盘系统控制功能提供必要参考输入。
