The invention provides an energy distribution control method and device for an electromechanical composite drive system. According to the method and the device, the number of electric drive axles involved in drive is dynamically adjusted according to the drive demand power, the gear of a transmission of a mechanical drive system and the gear of the electric drive axles of an electric drive systemare optimized, the output power of an engine, a power battery and a power unit are determined, and finally the power performance and economy of a vehicle are balanced. 本发明提供了一种机电复合驱动系统能量分配控制方法及装置，根据驱动需求功率，动态调整参与驱动的电驱动桥数量，优化机械驱动系统变速器挡位和电驱系统电驱动桥挡位，决定发动机、动力电池和动力单元的输出功率，最终实现平衡车辆的动力性和经济性。
