The invention discloses a stable energy output control strategy for a range-extended power system, and relates to the technical field of energy output control, the stable energy output control strategy comprises a whole vehicle control strategy and a range extender control strategy, in the whole vehicle control strategy, when the part, larger than the output energy of a power battery, of the whole vehicle demand energy is compensated by the output energy of a range extender, the whole vehicle demand energy is compensated by the output energy of the range extender; in the range extender control strategy, if the SOC of the power battery is larger than the lower limit value of the charge interval, the whole vehicle runs in a pure electric mode; if the SOC of the power battery is reduced to the lower limit value of the charge interval, a range extender is turned on, the whole vehicle runs in a range extending mode, and the control strategy adopted for the engine is determined according to the energy required by the whole vehicle; by formulating a reasonable and effective control strategy, the demanded power of the whole vehicle is optimally distributed between the two energy sources, the dynamic property and fuel economy of the whole vehicle are improved, efficient work of power components is guaranteed, and adaptability is high.

    本发明公开了一种增程式动力系统能量稳定输出控制策略,涉及能量输出控制技术领域,本发明包括整车控制策略和增程器控制策略,整车控制策略中,当整车需求能量大于动力电池输出能量的部分由增程器输出能量进行补偿,从而保证汽车正常行驶的能量需求,增程器控制策略中,若动力电池SOC大于荷电区间下限值,则整车以纯电动模式运行;若动力电池SOC下降至荷电区间下限值,则将增程器打开,整车以增程模式运行,根据整车需求能量的大小确定对发动机采用何种控制策略;本发明通过制定合理有效的控制策略,将整车的需求功率在两个能量源之间进行最佳分配,提高整车动力性和燃油经济性、保证动力部件高效工作,适应性强。
