The invention discloses a method and a system for predicting microcosmic energy consumption of a pure electric vehicle based on path induction. The method comprises the following steps: initializing basic energy consumption prediction information of the pure electric vehicle; defining a current vehicle driving direction; obtaining a corrected vehicle basic energy consumption set and a residual energy consumption set when the vehicle arrives at each intersection; judging the remaining electric quantity of the vehicle, if the vehicle is supported to reach the final destination intersection, ending calculation, and outputting the total energy consumption at the moment; if the remaining electric quantity does not support the vehicle to arrive at the nearest distance charging station and cannot arrive at the final destination intersection, traversing elements in the remaining energy consumption set and the lowest energy consumption set, searching for an early warning intersection, carrying out path optimization, recalculating energy consumption, carrying out path planning again based on the current starting point and the current ending point, and carrying out calculation by defining contents again. According to the method, the required energy consumption is calculated on the basis of the path induction premise after the road network information is obtained, the prediction accuracy is improved, and a more accurate and effective prediction method is provided for a driver.

    本发明公开了一种基于路径诱导的纯电动汽车微观能耗预测方法、系统,该方法包括初始化纯电动汽车能耗预测基础信息;定义当前车辆行驶方向;获取修正后车辆基础能耗集合和车辆到达各个交叉口的剩余能耗集合;判断车辆剩余电量,若支持车辆到达最终目的点交叉口,则计算结束,输出此时总能耗;若剩余电量不支持车辆到达最近距离充电站亦无法到达最终目的点交叉口,遍历剩余能耗集合和最低能耗集合内的元素,寻找预警交叉口,进行路径优化并重新计算能耗,基于当前起点与终点重新进行路径规划,再次定义内容进行计算。本发明考虑在获知路网信息后基于路径诱导前提计算出所需能耗,提高了预测准确度并提供给驾驶员一种更精准、有效的预测方法。
