【摘要】 混合动力电动汽车(Hybrid Electrical Vehicle,简称HEV)是将新技术和老技术结合的最可行的产物,它不仅具有纯电动汽车的高效率和低排放的性能,而且具有传统内燃机汽车的行驶里程长和快速补充燃料的性能,因此混合动力电动汽车成为当前解决节能、环保问题切实可行的方案。本文通过分析国内外HEV发展状况,阐述了当前在中国大力发展HEV的重要性、需要克服的技术难题以及HEV结合无级变速器(Continuous Variable Transmission,简称CVT)的特点和优势。在此基础上对典型的HEV动力总成系统进行了深入的分析,结合台架试验数据和理论分析,应用MATLAB/SIMULINK仿真语言自主设计搭建了CVT-HEV动力总成仿真平台。其次,在CVT-HEV仿真平台上研究了基于逻辑门限控制的混合动力电动汽车能源管理的控制策略,并结合工程实际编写了主控制器能源管理算法的控制流程图;同时对基于模糊逻辑的控制策略进行了探讨性的研究,并在仿真平台上对整车控制策略进行了仿真分析,为进一步的实车控制软件的开发提供了理论指导。最后,设计了配备CVT-HEV的动力总成控制系统基于CAN总线拓扑通信网络结构,并在J1939标准通信协议的基础上结合工程实际制定了基于CAN总线的CVT-HEV的控制器网络通信协议;并完成了CAN通讯模块和新型液晶显示仪表控制节点的软硬件设计。更多还原

【Abstract】 The Hybrid Electrical Vehicle is the feasible outcome from new and traditional Automobile technique. It not only has the advantages of low emission and high efficiency of Pure Electrical Vehicle, but also has the performances of long running mileage and fast fuel supplement in tradition internal-combustion engine automobile. Accordingly, Hybrid Electrical Vehicle becomes the feasible scheme for saving energy and protecting from environment in this century.In this paper, the worldwide development of HEV is analyzed. Along with the characteristic and superiority of combining HEV and CVT, the importance of developing HEV in China is presented. The typical HEV power assembly system is deeply analyzed on the basis of the development and study of the currently power assembly system. The mathematics model of combined coupling power assembly is built in combination with experimental data and theoretical analysis of the experimental bench. The professional simulation platform of CVT-HEV is designed and built by using MATLAB/SIMULINK simulation language.Then, the Hybrid Electric Vehicle Energy Management control algorithm based on logic threshold control method is studied on the CVT-HEV simulation bench. The control flow charts of the main controller energy management algorithm is written on the basis of the project. At the same time, the control algorithm based on fuzzy control has been studied on. The results and graphs of simulation based on CVT-HEV Energy Management Strategy which can be used for guiding the experiments are contended in the paper.Finally, the network’s topology of CVT-HEV power assembly control system is analyzed. Considering the practical project, the CAN Bus controller network communication protocol of HEV is established on the basis of J1939 protocol. Later on, the hardware and software of CAN module and the contronl node of liquid crystal display are developed.更多还原
