【摘要】 混合动力电动汽车(Hybrid Electric Vehicle)是传统燃油汽车和纯电动汽车相结合的新车型,具有燃油汽车的动力性能和较低的排放,是当前解决节能、环保问题切实可行的过渡方案。 目前混合动力电动汽车主要有3种混合驱动结构:串联式、并联式和混联式。本文对这3种混合动力系统结构和特点进行了分析,并重点介绍和分析了并联式结构中的不同结构特点,并分析了电动汽车专用分析软件Advisor的原理及使用方法。重点研究了Advisor2002自带的缺省并联混合动力电动汽车的驱动结构及其控制策略,在其基础上提出一种新型的混合动力电动汽车的系统模型,采用赛欧自动变速器作为传动机构,去掉离合器,以AT并联结构实现了四种工作模式。本文还对该系统建立了相应的控制策略,根据具体情况选择最合适的工作模式,并优化与发动机相关工作模式的性能,提高整车运行的燃油效率,减少尾气排放。在Matlab/Simulink环境中完成了这种新型混合动力电动汽车的传动系统和控制系统的建模,并在Advisor2002平台上,对其进行了系统仿真,将结果与缺省并联混合动力电动汽车的结果进行对比分析;最后把东风EQ7200的发动机、电池、电动机的数据用在所设计的AT并联混合动力系统上,并运行仿真,得出一个好的结果,证明此系统是可行的。 试验表明,这种新设计对缺省并联混合动力电动汽车有所改进,是一种可行的HEV设计方案。更多还原

【Abstract】 Hybrid Electric Vehicles (HEV) combines the advantages of conventional engine-driven vehicles and pure Electric Vehicles (EV). This provides satisfied driving performance and lower exhaust emission. Thus, HEV is a feasible solution to solve the energy crisis and environmental pollution problems.There are mainly three hybrid driving structures for the HEV at present: Series Schedule, Parallel Schedule and Series-Parallel Combined Schedule. The structures and features of the three hybrid power systems are analyzed in this paper. The different structures of the parallel type are introduced and analyzed emphatically. The performance request and systematic structure of Hybrid Electric Vehicle are introduced in this paper. The working basis and application of HEV specialized software Advisor 2002 is described in addition. A novel multi mode HEV systematic model is then presented basing on the research of Parallel HEV of Advisor 2002 , which focuses on its drive system’s structure and control strategy. The hybrid configuration proposed in the paper features saiou automatic transmission for an AT Parallel mode in addition to lay and realizes four operation modes in this structure. The vehicle control strategy is established to choose the most appropriate operation mode and optimize the overall vehicle operation involving the engine in terms of fuel economy and emission levels. The transmission and control system models are then established on the Matlab/Simulink platform and the overall system is simulated and analyzed in Advisor 2002; then, use engine data, electric storage data , motor data of dong feng EQ7200 in AT parallel model, and simulate, analyze, in the end ,receive a good result ,and prove that the AT parallel Schedule is feasible.The novel design shows improvement over parallel HEV of Advisor 2002 and is validated as a viable HEV design.更多还原
