摘　　要：为给辅助混合动力电动汽车的性能和分析提供一种新的手段,采用理论分析和试验数据相结合的建模方法,基于图形化建模仿真工具Matlab/Simulink建立了辅助混合动力电动汽车的仿真模型以及相应的控制器模型,并用该模型进行了一次充电续驶里程的仿真和分析,对该车在发动机运转和关闭2种状态下的仿真结果进行比较．结果表明,建立的仿真模型能很好跟踪循环工况,从而验证了仿真模型的正确性和有效性,也为进一步研究该车的设计和控制策略、完成性能的优化匹配、提高整车性能奠定了基础．To offer a new method which can forecast and analyze performance of an auxiliary hybrid electric vehicle, a computer simulation model and its controller were developed in the system simulation software Matlab/Simulink environment. The bench test results of key components of the hybrid powertrain were treated as reliable reference in the modeling. By using those models, the vehicle distance for specific drive cycle was simulated and analyzed. A comparison was made when engine is on and when engine is off. The results indicate the simulation model is in accordance with the specific drive cycle accurately so that the simulation model is effective. This study is helpful to the design of an auxiliary hybrid electric vehicle and the prediction of its performance.
