The invention provides a vehicle speed prediction method and device based on a driving condition and a driving style. The method comprises the steps of obtaining first vehicle speed data; based on the first vehicle speed data, performing classification through an identification model to determine a prediction index corresponding to the first vehicle speed data; querying the target mapping relationship according to the prediction index to obtain model configuration parameters, and updating the prediction model according to the model configuration parameters to obtain a target prediction model; and inputting the first vehicle speed data into the target prediction model to obtain second vehicle speed data, and performing vehicle energy management based on the second vehicle speed data. The method solves the problem that the prediction algorithm in the prior art does not integrate the driving condition and the driving style, so that the predicted vehicle speed result has large deviation.

    本申请提供了一种基于行驶工况和驾驶风格的车速预测方法和装置,获取第一车速数据;基于第一车速数据通过识别模型进行分类确定第一车速数据对应的预测指标;根据预测指标查询目标映射关系得到模型配置参数,根据模型配置参数更新预测模型得到目标预测模型;将第一车速数据输入目标预测模型,得到第二车速数据,基于第二车速数据进行车辆能量管理。该方法解决了现有技术中预测算法中并未综合行驶工况和驾驶风格,导致预测车速结果存在较大偏差的问题。
