The invention relates to a method and device for calculating oil consumption per unit mileage of an extended-range electric vehicle. The method comprises the steps that the power consumption per unitmileage is determined; the power generation amount of a range extender and the oil consumption of an engine are determined; extended mileage is obtained based on the power generation amount of the range extender and the power consumption per unit mileage, wherein the extended mileage refers to the number of mileage which can be increased if the power generation amount of the range extender is completely used for increasing the mileage; and the oil consumption per unit mileage of the extended-range electric vehicle is determined based on the oil consumption of the engine and the extended mileage. According to the method and device for calculating oil consumption per unit mileage of the extended-range electric vehicle disclosed by the technical scheme, the problem that in an existing scheme,when the oil consumption per unit mileage of the extended-range electric vehicle is calculated, the characteristics of the extended-range electric vehicle are not considered, and consequently the calculated oil consumption per unit mileage is low can be solved; and according to the method and device for calculating oil consumption per unit mileage of the extended-range electric vehicle disclosedby the technical scheme, the characteristics of the extended-range electric vehicle are fully considered, the calculated oil consumption per unit mileage is accurate, and a technical basis can be provided for accurately estimating the driving range of the vehicle subsequently.

    本公开涉及一种增程式电动汽车单位里程的耗油量计算方法及装置,该方法包括:确定单位里程的耗电量;确定增程器发电量和发动机耗油量;基于增程器发电量和单位里程的耗电量,得到扩展里程,扩展里程是指如果将增程器发电量全部用于增加里程,其可增加的里程数;基于发动机的耗油量和扩展里程,确定增程式电动汽车单位里程的耗油量。本公开实施例技术方案可以解决现有方案中计算增程式电动汽车单位里程的耗油量时,没有考虑增程式电动汽车的特点,致使所计算出的单位里程的耗油量偏低的问题,本公开实施例技术方案,充分考虑了增程式电动汽车的特点,所计算出的单位里程的耗油量准确,可以为后续准确地预估车辆的续驶里程提供技术基础。
