基于庞氏最小值原理,并以等效瞬时燃油消耗量最小为目标为某复合功率分流混合动力汽车制定了能量管理策略.利用MATLAB仿真平台,建立了混合动力系统能量管理策略的模型进行仿真.结果表明,与现有逻辑门限控制策略相比,采用等效瞬时燃油消耗量最小化的控制策略能显著提高燃油经济性.基于仿真结果,将控制策略集成到整车控制器中进行NEDC工况下的实车转鼓试验.结果显示,采用的控制策略使实车当量油耗降低了12.31%.%Based on Pontryagin's minimum principle and with minimizing equivalent instantaneous fuel con-sumption as objective, the energy management strategy for a compound power-split hybrid electric vehicle is formu-lated. A model for that energy management strategy of HEV is set up with MATLAB platform and a simulation is conducted. The results indicate that compared with existing logic threshold control strategy, using equivalent instan-taneous fuel consumption minimization strategy can significantly enhance fuel economy. Based on simulation results, the control strategy formulated is integrated into vehicle controller and a real vehicle drum test is performed under NEDC driving cycle with a result showing that using the control strategy formulated make the equivalent fuel con-sumption of vehicle reduces by 12 . 31%.
