The invention provides a control method, device and equipment for reducing fuel consumption of a range extending type automobile and a storage medium, and the method comprises the steps that when it is judged that the automobile enters a climbing state, the current gradient change proportion is calculated; calling a range extending strategy calibration database, wherein the range extending strategy calibration database comprises multiple groups of gradient change ranges and generated power corresponding to each group of gradient change range; traversing the range extending strategy calibration database, and obtaining the generated power corresponding to the current gradient change proportion; driving a range extender to generate electricity according to the generated power, and maintaining the remaining capacity of the battery to be greater than or equal to a first preset threshold; compared with the prior art, the range extender can generate electricity as much as possible according to the amount of electricity used by the battery, so that the range extender can be used immediately after generation, additional power generation is not needed, and mismatching of power generation caused by climbing is reduced, so that the consumption of fuel oil of an automobile can be effectively reduced.

    本申请提供降低增程型汽车油耗的控制方法、装置、设备及存储介质,所述方法包括:判断车辆进入爬坡状态时,计算当前坡度变化比例;调用增程策略标定数据库,所述增程策略标定数据库包括:多组坡度变化范围和每组所述坡度变化范围对应的发电功率;遍历所述增程策略标定数据库,获取与当前坡度变化比例对应的发电功率;以该发电功率,驱动增程器发电,维持电池剩余电量大于或等于第一预设阈值;与现有的相比,电池用多少电增程器就会尽可能的发多少电,做到即发即用,无需额外发电,减少由爬坡引发的发电不匹配,故能够有效地降低汽车燃油的消耗。
