【摘要】 混合动力电动汽车(Hybrid Electric Vehicle,HEV)是改进的内燃机汽车技术与建立在信息技术基础上的纯电动汽车技术相结合的产物,具有纯电动汽车和传统内燃机汽车的综合优点,是相当长时间内缓解汽车工业能源短缺和环境污染问题的一个可行的过渡方案。 城市交通拥挤,汽车时走时停,行车速度慢,尾气排放污染严重。城市公交车一般是在固定道路,固定时间运行,每日运行的总里程大多在300km左右。在这种情况下,传统的内燃机油耗高和排放污染大,而混合动力城市客车可以发挥其优势,降低油耗,改善排放。混合动力驱动系统较传统驱动系统增加了一些设备,增加了车辆的重量和体积,相对于轿车,这些变化对城市公交大客车的影响较小。所以,许多专家认为,混合动力技术将首先在城市公交客车上实现产业化。 混合动力城市客车可采用串联或并联方案,分别有其优缺点。本文采用技术比较成熟的铅酸电池、交流感应电机、电控柴油发动机等组成一个混联布置的混合驱动系统。文中对驱动系统中所涉及的主要子系统,如电池、电机和发动机等进行了简要的介绍和分析建模:简要介绍了混合动力仿真软件——ADVISOR2002;较为详细地介绍了所选驱动系统控制策略的控制目标、控制模式以及确定控制策略时需要考虑的关键问题。文中也介绍了武汉理工大学混合动力课题研究组开发的混合动力仿真软件BondHEV1.0。 本文的主要工作是提出了一种混联式混合动力城市客车驱动系统的机电偶合方案,分析了该系统的各种工作模式和动力及能量流,针对汽车的某一运行工况,以维持电池SOC平衡为主要目标,设计了该驱动系统的控制策略,基于ADVISOR2002,建立该驱动系统的仿真模型并进行系统仿真。仿真结果表明,本文所提出的控制策略和仿真模型能满足该混合动力城市客车驱动系统的设计要求。更多还原

【Abstract】 Nowadays, the most feasible compromise in applying a combination of new and old technology is provided by hybrid electric vehicle, which provides the benefits of both electric(EV) and traditional internal combustion vehicle, while minimizing the limitations of each. Hybrid Electric Vehicle is the most feasible solution to solve the energy and pollution problems in long time.City public transit is very crowded, and stops frequently, has slow driving speed and extremely serious pollution. City bus has fixed traveling line and regular run time normally;the total course that transit bus runs everyday is around 300 kms mostly. Under this kind of condition, the emission and the fuel economy of conventional transit bus are bad. But Hybrid Electric Bus (HEB) can just develop its advantages. HEV has more components than conventional vehicle, so it increases weight and volume. But it has less influence on big transit bus than on car. So many experts think the HEB will realize its industrialization firstly. The Ministry of Science and Technology of China has also set the development of HEV and HEV components as one of the most important sub-projects in the 863 Program.No mater the configuration of the hybrid power train of HEB is parallel or series;there are advantages and disadvantages at the same time. HEB is decided to adopt the configuration in SPHEV;the components of the power train include the lead acid battery, AC induction motor and diesel engine. In this paper, the author gives a presentation and analyse on the power train subsystem, such as battery, motor and genertor. Moreover, the thesis also introduces the simulation software of HEV— ADVISOR2002.This thesis introduces control aim, control model and sixty-four-dollar questions of the control strategy. The simulation software of HEV-BondHEV1.0 exploited by Wuhan University of Technology HEV study is mentioned.An electromechanical coupling of the powertrain for a kind of SP hybrid electric city bus is proposed, analyse this system’s all kind of work modle and power flow.For some drive cycle, in order to maintain the batteries’ SOC, the control strategy for the powertrain is designed under a driving cycle. A simulation model based on ADVISOR2002 is set up also. From the results of simulation, the control strategy and simulation models can meet the need of the design target for the hybrid electric city bus powertrain.更多还原
