【摘要】 日益严重的能源和环境问题,使得人们对于节约能源和环保意识显著提高,混合动力汽车作为一种能节约能源和达到环保目的的交通工具,在近20年有了长足的发展。随着相关立法的日趋严格,混合动力汽车已成为本世纪重点发展的新型汽车。客车作为城市公用交通工具,使用混合动力驱动形式同样必要。本文首先分析了三种混合动力形式的优缺点,介绍了现在混合动力技术的研究现状和发展趋势。再结合城市公交行驶路况,分析了适合城市公交的混合动力形式,并最终确定并联型混合动力客车为研究方向。按照城市客车的工况要求对混联式混合动力车的动力系统部件进行选型,根据样车的使用要求,对动力系统进行了概念设计,并进一步对各关键部件进行了形式研究,初步确定了部件的参数,提出动力系统匹配方案。详细介绍ADVISOR2002(Advanced Vehicle Simulator 2002)。在充分研究已有模型的基础上,再以MATLAB为工作平台,确定并建立混合动力汽车的发动机、交流感应电机和蓄电池等系统部件模型,并对原仿真模型进行了二次开发,建立ADVISOR可用的后轮驱动并联混合动力汽车模块。对混合动力汽车的控制策略进行研究,确定使用电力辅助控制策略。输入混合动力汽车的仿真参数,使其在CYC1015循环工况下仿真,通过与原车的模拟仿真结果比较可知,整车的动力性能与设计目标基本符合,并联混合动力客车的动力性能、经济性得到改善。本论文所做的研究将有助于缩短混合动力汽车的设计开发时间,为其驱动系统的设计和控制策略及整车性能评估提供参考。
【Abstract】 With the deterioration of energy and environment, people realize that saving energy and protecting environment is very important. HEV is a good vehicle to reach this goal. During the recent 20 years, the technology in this field is developed quickly. As the interrelated law become strict, HEV is becoming an important developing new vehicle. As the urban bus is the most public vehicle, using hybrid is also necessary.In this article, three different kinds of hybrid drive type are analyzed, the hybrid technology nowadays and developing tendency are introduced. With the real urban bus driving way, the proper way for urban bus is analyzed. Finally, the PHEV is determined to use for the bus design.The power system of the PHEV is designed with the status of urban driving. Parallel hybrid drive train is selected as the drive system of the prototype according to its use requirement. The structure of the drive system is conceptive designed. The parameters of the key components are computed and optimally matched by the analysis of the system and their special characteri -stics.Introduced ADVISOR2002(Advanced Vehicle Simulator 2002) in detail, based on Matlab/simulink modeling environment. Construct the models of engine, AC motor and battery of PHEV by making reference to the model presented. Then, develop new simulation models, the rear wheel drive components are modularized and can run in the ADVISOR.Analyzed several control strategies of Hybrid Electric Vehicle, designed the power train based on the parallel electric assistant control strategy. Simulate the PHEV under the CYC1015 cycle in advisor with the parameters of the key components. Comparing with the simulation results of conventional vehicle, the power performance showed accord with the design goal, and we can make a conclusion that the PHEV has better vehicular dynamic performance and fuel economy.The study of this paper would be helpful to reduce the period of design for HEV and supply the reference for drive train design, control strategy and vehicle’s performance evaluation.
