【摘要】 混合动力电动汽车(Hybrid Electric Vehicle)是汽车技术不断发展的产物,既具有纯电动汽车高效率和低排放或零排放的特性,又具有传统内燃机汽车动力性强和续驶里程长的优点,是当前解决节能、环保问题切实可行的一种过渡方案。目前,混合动力电动汽车主要有三种驱动结构类型:串联式、并联式和混联式。通过客观分析比较这三种类型混合动力电动汽车的结构特性及优缺点,综合考虑对车辆的实际使用要求及成本问题等因素,本文所设计的车辆选择了并联式的混合动力驱动系统。本文以风神蓝鸟为设计原型,通过重新设计其驱动系统将风神蓝鸟设计成并联式混合动力电动汽车。根据风神蓝鸟的动力性指标,确定本文设计车辆的发动机功率、电动机功率、蓄电池功率、主减速比和变速器速比等参数及驱动系统主要部件的类型。分析了电动汽车专用仿真软件ADVISOR的原理及使用方法,建立了发动机、电动机、蓄电池、变速器等各部件模型及整车模型。在MATLAB/Simulink环境下,以ADVISOR为仿真平台,在仿真软件中输入仿真参数、设置测试性能、选择循环工况,分别对风神蓝鸟和本文设计的车辆进行仿真运算,分析比较仿真结果。结果表明:本文设计的并联汽车和风神蓝鸟相比,在不降低动力性的前提下大幅度提高了燃油经济性和改善了排放性能,具有良好的工程应用前景和实际应用的社会、经济效益。另外,本文还对部分参数进行了优化,对比分析了不同控制策略对本文设计的并联式混合动力电动汽车整车性能的影响,确定了适合于本文所设计车辆的控制策略。

【Abstract】 Hybrid Electric Vehicle is a product of the continuous development of technology, not only have the high efficiency and low emissions or zero emission performances of pure electric vehicles, but also have the advantage of traditional internal combustion engine vehicle with strong impetus and continued driving mileage. It’s the practical transition program to solve the energy conservation and environmental protection in current. At present, Hybrid Electric Vehicle have three main types of drivetrain structure: the Series, Parallel and Parallel-Series. Through objective analysis and comparing the properties of the structure and the advantages or disadvantages of those hybrid vehicles , and considering the actual use requirements of the vehicle and costs or other factors, this paper chosed the Parallel drivetrain system.Fengshen Bluebird as a design prototype in this paper. Through redesign the drivetrain system of Fengshen Bluebird, we made Fengshen Bluebird became a Parallel Hybrid Electric Vehicle. According to the momentum indicators of Fengshen Bluebird, we determined the main parameters of the vehicle which we designed in this paper ,such as engine power, motor power, battery power, final ratio, gear ratios and the types of the main components. Analysised the principle of the ADVISOR which is a dedicated simulation software for Electric Vehicle and how to use it. Built up the models of engine, motor, battery, transmission or other parts and the whole vehicle. Under MATLAB / Simulink conditions, we input the simulation parameters, set up the test performances and choose the cycle conditions base on ADVISOR .Carry out simulation computing for Fengshen Bluebird and the vehicle which we design respectively and analysis simulation results. The results show that: the Parallel Hybrid Electric Vehicle which we designed compare with Fengshen Bluebird has greatly increased fuel economy and improved emissions performance without lower impetus. And has a good prospect of application and the practical application of the social and economic benefits. In addition, the paper also optimized some parameters and comparatively analysised the effect on the Performance of the whole vehicle under different control strategies. And determined the fitable control strategy for the vehicle which we designed.
