The invention discloses a remaining mileage estimation method for an electric vehicle. The method comprises the following steps: 1, acquiring vehicle body parameters and vehicle surrounding environment data of a new energy vehicle; 2, performing path planning according to a destination input by a driver, and screening out a preferred path; 3, detecting traffic data on a route according to an optimal route obtained by route planning; 4, importing the obtained data into a comprehensive operation module, and obtaining predicted specific energy consumption data through operation; 5, obtaining the endurance mileage according to the residual electric quantity of the battery; and 6, according to the obtained energy consumption data and the endurance mileage, judging whether the vehicle can smoothly arrive at the destination or not. According to the method, the accuracy of estimating the endurance mileage of the new energy automobile in the path planning process aiming at the target location on the actual road can be improved.

    本发明公开了一种电动汽车的剩余里程预估方法,包括:1.对新能源汽车的车身参数和车周环境数据进行获取;2.根据驾驶员输入的目的地,进行路径规划,筛选出优选路径;3.根据路径规划得到的优选路径,对该路线上的交通数据进行检测;4.将所得数据导入综合运算模块,通过运算获得预测的具体能耗数据;5.根据电池剩余电量获得可续航里程;6.根据获得的能耗数据与可续航里程,判断能否顺利到达目的地。本发明能够提高新能源汽车实际道路上针对目标地点的路径规划过程中的可续航里程估计的准确性。
