基于扩展Petri网建模的混合动力汽车能耗分析研究

摘要

A modelling method of extended colored stochastic Petri nets (ECSPN) was presented to analyze and optimize the driving system of hybrid electric vehicle (HEV ) based on the energy consumption of battery .With the method ,the function between the hybrid vehicle system components and the integrated lifetime models could be determined .The driving system of strong HEV was simulated and researched and the switch time and process between different operating modes were optimized . The results show that the modelling method is feasible .%以混合动力电动汽车电池能耗分析为切入点，提出一种利用扩展有色随机 Petri网（ECSPN ）的建模方法来分析、优化混合动力汽车驱动系统，利用这种方法可以确定混合动力汽车系统组件与集成寿命周期模型之间的函数关系。对1辆强混混合动力汽车驱动系统进行仿真研究，利用仿真结果对混合动力电动汽车不同操作模式间的切换时间以及切换过程进行优化，仿真结果表明此种建模方法是可行的。
