The invention relates to the technical field of hybrid power vehicles, in particular to a power assembly control method for a hybrid power vehicle. The power assembly control method for the hybrid power vehicle comprises three control strategies, which are separately a rule based steady-state optimization control strategy, a real-time control based dynamic optimization control strategy and a fuzzycontrol based intelligent control strategy; the rule based steady-state optimization control strategy has three independent control parameters, which are separately an electric quantity state controlparameter, a speed control parameter and a torque control parameter; and the electric quantity state control parameter adopts a SOC value to mark while a SOC value of a storage battery is higher thana set lower limit soc low. The power assembly control method can regulate power output of a vehicle in real time according to a road condition by selecting a vehicle traveling road condition, and canmaximize power energy efficiency in the vehicle, thereby reducing loss of energy, greatly increasing economic benefits and reducing pollution on environment.

    本发明涉及混合动力汽车技术领域,尤其涉及一种混合动力汽车动力总成控制方法,本发明混合动力汽车动力总成控制方法分为3种控制策略,分别是基于规则的稳态优化的控制策略、基于实时控制的动态优化控制策略以及基于模糊控制的智能控制策略;基于规则的稳态优化的控制策略中共有3个独立的控制参数,分别是电量状态控制参数、速度控制参数和转矩控制参数;电量状态控制参数采用SOC值进行标志,当蓄电池SOC值高于其设定下限soc_low时。本发明根据车辆行驶的路况进行选择,能让车辆的动力输出实时根据路况进行调整,能将车内的动力能源效率最大化。减少能量的损失,极大的增加了经济效益和减少了对环境的污染。
