The invention provides a vehicle energy consumption prediction method and device, equipment and a medium, and the method comprises the steps: obtaining a first sample closest to a current moment from samples of a plurality of historical moments, the first sample comprising an actual unit mileage energy consumption value of a vehicle in a first historical time period and data of a plurality of feature indexes at the first historical moment, the first historical time period is a time period after the first historical moment; determining target weights corresponding to the plurality of feature indexes according to the data of the plurality of feature indexes at the first historical moment, the first weights corresponding to the plurality of feature indexes and the actual energy consumption value per unit mileage in the first historical time period; and based on the data of the plurality of feature indexes at the current moment and the target weights corresponding to the plurality of feature indexes, determining a target unit mileage energy consumption value in the future time period. According to the method, the target weights of the plurality of characteristic indexes are dynamically changed, so that the accuracy of the target unit mileage energy consumption value is improved.
本发明提供一种车辆能耗预测方法、装置、设备及介质,其中方法包括:从多个历史时刻的样本中获取距离当前时刻最近的第一样本,第一样本中包括车辆在第一历史时段的实际单位里程能耗值以及多个特征指标在第一历史时刻的数据,第一历史时段为第一历史时刻之后的时段;根据多个特征指标在第一历史时刻的数据、多个特征指标对应的第一权重以及第一历史时段的实际单位里程能耗值,确定多个特征指标对应的目标权重;基于多个特征指标在当前时刻的数据以及多个特征指标对应的目标权重,确定未来时段的目标单位里程能耗值。本发明中多个特征指标的目标权重动态变化,有利于提高目标单位里程能耗值的准确性。
