基于Matlab/Simulink的混联式混合动力电动汽车建模与仿真

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。

Modeling and Simulation of Parallel-Series Hybrid Electric Vehicle Based on Matlab/Simulink

A parallel-series hybrid electric vehicle (PSHEV) model is built up in Matlab/Simulink, and the mode logic of vehicle 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 comparing 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 energy saving and emission reduction.
