The invention discloses an electric vehicle driving range prediction method and device. The method comprises the following steps: acquiring the available electric quantity and the driving resistance of the vehicle, wherein the driving resistance is the estimated resistance generated by the vehicle in a future driving road section; obtaining the driving power of the vehicle according to the drivingresistance of the vehicle; according to the use state of the vehicle-mounted accessory of the vehicle and the historical use data of the vehicle-mounted accessory by the user, obtaining the consumedpower of the vehicle-mounted accessory; and finally, obtaining the driving range of the vehicle according to the available electric quantity, the driving power and the consumed power. According to themethod, the actual use state of the vehicle on a future road section and user habits are considered, and the accuracy of driving range prediction is remarkably improved.

    本发明公开了一种电动汽车续驶里程预测方法及装置,所述方法包括:获取车辆的可用电量以及行驶阻力;其中,所述行驶阻力为预估的所述车辆在将来行驶路段中产生的阻力;根据车辆的行驶阻力,获得车辆的行驶功率;再根据车辆的车载附件的使用状态以及用户对车载附件的历史使用数据,获得车载附件的消耗功率;最后,根据可用电量、行驶功率以及消耗功率,获得车辆的续驶里程。本发明考虑了车辆在将来路段的实际使用状态以及用户习惯,显著提高了续驶里程预测的准确性。
