The invention relates to the technical field of electric vehicles, in particular to an electric vehicle remaining driving range prediction method and device considering a road environment, and the method comprises the steps: calculating a speed energy consumption correction factor, a slope energy consumption correction factor and a temperature energy consumption correction factor according to historical actual road driving data of an electric vehicle; matching at least one historical travel route of the electric vehicle according to the obtained actual travel starting point and the actual travel ending point of the electric vehicle; reading speed energy consumption, slope energy consumption correction factors and temperature energy consumption correction factors of at least one historical travel route, and calculating actual travel energy consumption and required energy of the at least one historical travel route in combination with the current travel temperature and the predicted travel speed; and calculating the actual remaining driving range of the electric vehicle according to the calculated actual travel energy consumption and the battery energy. Therefore, the problem that the accuracy of the driving range prediction result is not high due to the fact that the influence of the actual road complex composite environment on the energy consumption is not considered in the related technology is solved.

    本申请涉及电动汽车技术领域,特别涉及一种考虑道路环境的电动汽车剩余续驶里程预测方法及装置,其中,方法包括:根据电动汽车的历史实际道路行驶数据计算速度能耗、坡度能耗修正因子和温度能耗修正因子;根据获取的电动汽车的实际出行起点和实际出行终点匹配电动汽车的至少一条历史出行路线;读取至少一条历史行驶路线的速度能耗、坡度能耗修正因子和温度能耗修正因子,结合当前出行温度和预测出行速度,计算至少一条历史出行路线的实际出行能耗及所需能量,并根据计算实际出行能耗及电池能量计算所述电动汽车的实际剩余续驶里程。由此,解决了相关技术中未考虑到实际道路复杂复合环境对能耗的影响,导致续驶里程预测结果的准确度不高等问题。
