The invention discloses a method and device for determining an engine power threshold of a vehicle and a storage medium. The method comprises the steps of obtaining an actual electric quantity value of a battery of a vehicle; based on the actual electric quantity value, the electric quantity lower limit value of the battery and the electric quantity balance value of the battery, a target coefficient of the battery is determined, and the target coefficient is used for determining engine power; comparing the target coefficient with a coefficient threshold value of the battery to obtain a first comparison result; determining engine power based on the first comparison result; based on the engine power, an engine power threshold is determined. The technical problems that engine fuel economy under large-load battery assistance, medium-low-speed engine noise and electric quantity state balance under extreme working conditions cannot be effectively balanced are solved.

    本发明公开了一种车辆的发动机功率门限的确定方法、装置和存储介质。该方法包括:获取车辆的电池的实际电量值;基于实际电量值、电池的电量下限值和电池的电量平衡值,确定电池的目标系数,其中,目标系数用于确定发动机功率;对目标系数和电池的系数阈值进行比较,得到第一比较结果;基于第一比较结果,确定发动机功率;基于发动机功率,确定发动机功率门限。本发明解决了无法有效平衡大负荷电池助力下的发动机燃油经济性、中低车速发动机噪声以及极端工况下的电量状态平衡的技术问题。
