The invention discloses a range extender model selection method which comprises the steps of dividing vehicle driving power into a plurality of intervals, determining a working condition point pi in each interval, and obtaining actual working condition point oil consumption APU-FCi corresponding to the working condition point pi; calculating the circulating working condition oil consumption of range extenders according to the plurality of actual working condition point oil consumptions; and selecting the range extender with the lowest oil consumption under the circulating working condition according to the circulating working condition oil consumption. Therefore, the circulating working condition oil consumption of the range extenders is obtained based on the actual working condition pointoil consumption of each working condition point, so that the representation significance of the circulating working condition oil consumption is more accurate, the oil consumption and the energy efficiency ratio of the range extenders can be accurately reflected, the model selection of the range extenders is facilitated, and the model selection of the range extenders of a finished automobile factory is more reasonable; the selected range extender is lower in oil consumption and higher in energy efficiency ratio.

    本申请公开了一种増程器的选型方法,所述选型方法包括:将车辆驱动功率划分为多个区间,每个区间内确定一个工况点pi,并获取与之对应的实际工况点油耗APU‑FCi;根据多个所述实际工况点油耗计算出増程器的循环工况油耗;根据循环工况油耗选取循环工况油耗最低的増程器。由此,基于每个工况点的实际工况点油耗求得増程器的循环工况油耗,使循环工况油耗的表征意义更加准确,可以准确地体现増程器的油耗以及能效比,从而方便増程器的选型,并使整车厂的増程器选型更加合理,选取后的増程器的油耗更低、能效比更高。
