一种电动汽车及其续驶里程预测方法、系统
摘要：
本申请公开了一种电动汽车及其续驶里程预测方法、系统，该方法包括：获取当前电动汽车的行驶信息；利用行驶信息，确定当前电动汽车所在行驶道路的道路类型，得到目标道路类型；确定与目标道路类型对应的单位能耗，并获取电动汽车的当前电池状态；利用单位能耗以及当前电池状态，计算当前电动汽车可持续行驶的里程数。本申请中的单位能耗是与道路类型相对应的，能够更加贴合当前电动汽车所行驶道路的实际情况，也即使得上述单位能耗与当前电动汽车的实际能耗更加一致，具有非常高的准确度，从而提升了后续依赖上述单位能耗计算出来的可持续行驶里程数的准确度。综上，本申请能够对电动汽车剩余的续驶里程进行更加准确的预估。
摘要（英）：

The invention discloses an electric vehicle, a driving mileage prediction method and a system thereof. The driving mileage prediction method includes the steps of obtaining the current driving information of the electric vehicle; determining the type of a driving road where the electric vehicle currently runs on according to the driving information and obtaining the type of a targeted road; determining the unit energy consumption corresponding to the type of the targeted road and obtaining the current battery state of the electric vehicle; and calculating a driving mileage that the electric vehicle can currently continue to drive for according to the unit energy consumption and the current battery state. According to the driving mileage prediction method, the unit energy consumption corresponds to the road type so as to better fit the practical conditions of the road where the electric vehicle runs on and make the unit energy consumption more coincident with the current practical energy consumption of the electric vehicle, and thus the accuracy is very high, and accordingly the accuracy of the following sustainable driving mileage calculated based on the unit energy consumption is improved. As a conclusion, the driving mileage prediction method can predict the remained driving mileage of the electric vehicle more accurately.
