The invention provides a method and a device for predicting the travel energy consumption of a vehicle. The method comprises the following steps: training to obtain a vehicle road section energy consumption prediction model of each vehicle on each road section and a vehicle type road section energy consumption prediction model of each vehicle type on each road section according to pre-collected travel records of a plurality of vehicles in a preset area; generating a default road section energy consumption prediction model of the vehicle according to the default energy consumption of the vehicle or the vehicle type to which the vehicle belongs; connecting the models on the adjacent road sections to respectively generate vehicle, vehicle type and default consumption prediction grids; and on the basis of the grids, predicting the total energy of the target vehicle on a candidate travel path by utilizing at least one of the vehicle, the vehicle type and the default road section energy consumption prediction model (the priority selection sequence is the former) of the target vehicle. Personal driving habits, road condition information and travel conditions are comprehensively considered, the accuracy of the energy consumption prediction result can be improved, engineering implementation is easy, and the method has the advantages of being small in calculation amount, low in implementation cost and the like.

    本发明提供了一种车辆行程能耗的预测方法及装置。所述方法包括:根据预先收集的预设区域内多个车辆的行程记录,训练得到每一车辆在每一路段的车辆路段能耗预测模型和每一车型的车辆在每一路段的车型路段能耗预测模型;根据车辆或车辆所属车型的默认能耗,生成车辆的默认路段能耗预测模型;连接相邻路段上的上述模型分别生成车辆、车型和默认耗预测网格;基于上述网格,利用目标车辆的车辆、车型和默认路段能耗预测模型中的至少一个(优先选择顺序靠前者),预测目标车辆在候选出行路径上的总能量。本发明综合考虑了个人驾驶习惯、路况信息和出行条件,能够提高能耗预测结果的准确性,且易于工程化实施,具有计算量较小,实施成本较低等优点。
