多用途轮式自动行走小车的设计
摘要
本文针对电动车的理想车型——双轮独立驱动电动车的驱动系统，对与上述EV的车辆动力学特性和电动车相关的轮毂式永磁无刷直流电机进行了深入的分析，基于当前电动车（EV）产业的兴起与发展进行了相关的研究和实验验证。
目前电动车发展中的一项关键技术是蓄电池技术，但同时也是电动车的薄弱环节，动力蓄电池已经成为电动车产业化的主要障碍。不同种类的蓄电池拥有不同的性能，而同一类型的蓄电池的不同个体也存在相当大的个体差异，这些差异对蓄电池组的性能会有影响，从而对电动车的整体性能也有影响。本中也涉及了有关电动车动力蓄电池性能的介绍。
电力机车技术的发展越来越受到广泛关注，其中控制系统性能的好坏对电动车的发展越来越重要，控制系统也逐渐引起了人们的关注。控制系统性能的关键是发挥控制系统的最大功效，因此研究电力机车控制系统也已经成为当今电动车领域一个重要的课题。现有的电力机车控制系统包括微机控制系统、逻辑控制系统、显示系统等，关键是如何将他们有机的结合起来并发挥出尽可能大的功效。本的写作过程中查阅了相关的资料，提出了一套以车指令系统+微机控制系统+逻辑控制系统的系统控制策略。

ABSTRACT
Based on the development of electric vehicles (EVs) industrial ,this paper describes an ideal concept EV, that is a EV has independent directly driven wheels (In-wheel EV). The research into drive systems concerns theoretical analysis and correlative experiment. The research on the permanent magnet brushless in-wheel motors and vehicle dynamics used for this novel EV is presented.
As the feeble section of electric vehicle, power battery was the main obstacle of the industrialization of electric vehicle. Designing a sound battery management system was one of the key technologies of electric vehicles. It was known that the performance difference among different kinds of batteries and considerable individual difference among the same kind of battery had great influence on the performance of battery team and the whole capability of electric vehicle. This article mainly describles the whole capability of power battery of the electric vehinle.
With the development of electric locomotive, the performance of locomotive control system is more and more took into account. How to combine the microcomputer control system, logic control system, display system with locomotive security system, and make the best use of control system is task of research of the electric locomotive control system. According to the other paper,this article expounds a strategy of control system based on locomotive instruction system,microcomputer control system, logic control system.
