摘要
在Matlab/Simulink环境下建立混联式混合动力电动汽车(Parallel-Series Hybrid Electric Vehicle,PSHEV)模型,并用Stateflow建立整车控制器的模式逻辑模型。在欧洲城市道路循环工况(European Urban Road Driving Cycle,CYC_ECE_EUDC)下对整车动力性能、燃油经济性能与排放性能进行仿真分析。仿真结果表明:与Advisor/Prius在相同工况下的仿真结果相比,所建立模型符合混联式混合动力电动汽车的整车动力学要求,模型具有正确性和可行性,且采用所建立的能量分配控制策略,百公里油耗为5.056L,较Advisor/Prius模型同比下降2.8%,CO排放量和NOx排放量分别降低16.9%和2.7%,实现控制策略的有效性,达到节能减排的目的。
A parallel-series hybrid electric vehicle （PSHEV） model is built up in Matlab/Simulink, and the mode logic of vehi- cle controller is modeled with Stateflow. Power performance, fuel economy and emissions performance of hybrid are compared by analysis of simulation using the European urban road driving cycle （CYC_ECE_EUDC）. The results of simulation show that com- paring with the Advisor/Prius, in the same conditions, the model conforms to PSHEV dynamic requirements and is of correctness and feasibility, what＇ s more, it uses the energy distribution control strategy, so that the fuel consumption per hundred kilometers is about 5. 056L, which is 2.8% less than that of the Advisor/Prius, the emissions of CO and NOx are reduced by 16.9% and 2.7%. The simulation results indicate the effectiveness of the control strategy. The using of PSHEV achieves the purpose of ener- gy-saving and emission reduction.
