The invention relates to a dynamic optimization method for heating energy consumption of a vehicle air conditioner. According to the temperature requirements of passengers in the vehicle passenger compartment at the t moment, the air conditioner heating demand x (t) in the passenger compartment is obtained, meanwhile, the cooling water outlet temperature y (t) in an engine and the remaining electric quantity z (t) of a power battery are obtained, the engine waste heat quantity Qw (t) is obtained, whether the air conditioner heating demand x (t) exceeds the engine waste heat quantity Qw (t) or not is judged, and if yes, after a balance relation is established, the air conditioner heating demand x (t) is judged to be larger than the engine waste heat quantity Qw (t); the method comprises the following steps: acquiring an output power form expression P1 (t) of a power battery and an energy supply power form expression P2 (t) of a range extender, then establishing a target function, and calculating an output power true value of the power battery and an energy supply power true value of the range extender through an algorithm program; if not, heat is supplied to the passenger compartment through the engine; according to the method, the optimal allocation can be directly found by utilizing an intelligent algorithm without depending on expert judgment.

    本发明涉及一种车辆空调制热能耗动态优化方法,具体步骤包括;根据t时刻车辆乘仓中乘客的温度需求,得到乘仓中空调制热需求量x(t),同时获取发动机中冷却出水温y(t)以及动力电池的剩余电量z(t),获得发动机余热量Qw(t),并判断空调制热需求量x(t)是否超过发动机余热量Qw(t),若是,则建立平衡关系后,获得动力电池的输出功率形式表示P1(t)和增程器的供能功率形式表示P2(t),随后建立目标函数,通过算法程序计算出动力电池的输出功率真实值和增程器的供能功率真实值;若否,则通过发动机向乘仓供热;通过本发明可以不依赖专家判断,利用智能算法直接寻到最优分配。
