The invention provides a hybrid power system energy efficiency calculation method, a hybrid power system energy efficiency calculation system and a vehicle, and relates to the technical field of software. The hybrid power system energy efficiency calculation method specifically comprises the following steps: calculating the equivalent discharge efficiency of a power battery; identifying a drivingmode of the vehicle; and calculating the system energy efficiency by combining the equivalent discharge efficiency of the power battery according to different driving modes. The hybrid power system energy efficiency calculation method calculates according to the equivalent discharge efficiency of the power battery, so the problem that the calculated energy efficiency of the system is too high dueto the fact that the discharging efficiency of the battery is directly adopted is solved, the accuracy of switching the power of the vehicle according to the calculated energy efficiency of the systemis guaranteed, and then the purpose of saving oil is achieved.

    本发明提供了一种混合动力系统能量效率的计算方法、计算系统和车辆,涉及软件技术领域。具体本发明的所述混合动力系统能量效率的计算方法包括:计算动力电池的等效放电效率;识别车辆的驱动模式;根据不同驱动模式,结合动力电池的等效放电效率计算获得系统能量效率。本发明的混合动力系统能量效率的计算方法根据动力电池等效放电效率进行计算,避免了直接采用电池的放电效率而造成计算的系统的能量效率偏大的问题,从而保证了车辆根据计算出的系统能量效率进行车辆的动力进行切换的准确性,进而达到节油的目的。
