摘　　要：以单轴并联式混合动力电动汽车为研究对象,基于混合动态系统理论,利用混合输入输出自动机模型,直观的描述了混合动力系统,分析得出了多能源功率分配和工作模式切换序列的基本规律,系统的阐述了能量最优化分配和工作模式最佳切换序列的工程实现,为进一步实现性能的优化匹配和协调控制,提高整车性能奠定了一定的基础。通过与Advisor中Insight车型的仿真结果对比,验证了基于混合动态理论能量管理策略的实际效能。A signal axel parallel HEV was set as the study object. Based on the concept of hybrid dynamic system and the model of hybrid automata, a visualized mathematical description of HEV was completed and rules of the control strategies were proceed. At the same time, the power splitting and drive mode switch sequence control strategies were formatted. In the final, power of optimal distribution is realized through the suitable cost function. Compared with the results of the special simulation software Advisor, the simulation results show that the research is helpful to the design of a hybrid electric vehicle and prediction of its performance.
