【摘要】：纯电动汽车(Battery Electric Vehicle,简称BEV),是指完全由可充电电池(如铅酸电池、镍镉电池、镍氢电池或锂离子电池)提供动力源的汽车。纯电动汽车的核心技术依靠电机控制器控制电机扭矩输出,整个电动汽车系统上任意控制单元的正常工作都是依赖控制器的协调控制,因此,研发可靠安全高效率的电机控制器、控制性能优异的安全监测管理系统以及能够确保系统协调工作的纯电动车研发技术具有非常重要的意义。本文主要致力于,电动汽车电机驱动系统的故障诊断系统的一系列研究。对此设计研发了一系列比较完善的故障诊断办法,以及相应的保护措施,分析了电动汽车电机控制器的故障类型、故障危害级别,并对此进行了故障的级别划分以及相应的处理办法。并利用MATLAB搭建了故障诊断和保护措施的模型;最终将故障诊断系统应用在了实际的电动汽车测试项目中,得到良好的反馈,同时本文也介绍了针对汽车电机控制器的故障诊断的容错控制。最后本文将匹配电动汽车电机控制器的故障管理说明汇总,并介绍了故障管理系统与整车结构的通讯设计开发。本论文致力于对新能源汽车电机控制系统的安全可靠性的研究,为今后这方面的研究提供了可能的参考。
[Abstract]:Pure electric vehicle Battery Electric vehicle (BEV) refers to a car that is powered entirely by rechargeable batteries (such as lead acid batteries, nickel cadmium batteries, nickel hydrogen batteries or lithium ion batteries). The core technology of pure electric vehicle depends on the motor controller to control the motor torque output. The normal operation of any control unit in the whole electric vehicle system depends on the coordination control of the controller. It is of great significance to develop a reliable safe and efficient motor controller, a safety monitoring and management system with excellent control performance and a pure electric vehicle technology which can ensure the coordinated work of the system. This paper is mainly devoted to a series of research on the fault diagnosis system of electric vehicle motor drive system. For this design, a series of perfect fault diagnosis methods and corresponding protection measures are developed, and the fault types and fault hazard levels of electric vehicle motor controller are analyzed. The classification of the fault level and the corresponding treatment methods are also given. Finally, the fault diagnosis system is applied to the actual electric vehicle test project, and good feedback is obtained. At the same time, this paper also introduces the fault-tolerant control for automobile motor controller. Finally, this paper summarizes the fault management instructions of the matched electric vehicle motor controller, and introduces the design and development of the communication between the fault management system and the whole vehicle structure. This thesis is devoted to the study of the safety and reliability of the motor control system of the new energy vehicle, which provides a possible reference for the future research.
