摘     要
 电动汽车电机及其控制系统研究课题的一项重要内容和基本要求，包括硬件平台建设和应用软件开发两部分。
 试验台架是涉及一种混合动力汽车动力传动系统可靠性试验台架，它包括发动机、发动机控制器ECU、ISG电机、电机控制器IPU、动力蓄电池、电池管理系统BCM、测功机、台架控制系统和上层控制器HCU。本文档是阐述试验台架的电控设计方案，总体设计方案主要有数据板卡（硬件）和控制软件（VB程序）组成。控制软件主要负责控制信号的输出，数据板卡用于数模转换并向电机控制器控制信号的输出和转速、扭矩信号的采集转化并传输给控制软件。控制软件同时对数据进行滤波处理，然后显示在控制台面板上。
 电动汽车电机及驱动系统性能评价试验台架并不等同于传统的电机性能试验平台，必须考虑电动汽车电机驱动系统测试项目的特点，特别是要实现对汽车行驶道路工况的模拟。根据这样的设计思路，要求在平台硬件设计中，功率、转矩的测量装置除满足静态特性的测试外，还必须满足动态特性测试的要求，测控软件的开发必须考虑测功机转动惯量等动态特性因素的影响。
 试验台架实现了模拟汽车行驶时作用在电机输出轴上的实际负载，再现诸如起步、变速、制动等行驶过程，实现同道路试验相同或更为理想的电机运行工况的模拟，技术水平达到了目前国内同行业先进水平。

 The Test Project Design of Electric Control about Hybird Electric Vehicle
Abstract
 Developing a test bench for evaluating motor drive performance of Electric Vehicle (EV) is one of important tasks of researching on motor and its drive system of Electric Vehicle, which is one of the nation's 863 projects. The development of the test bench includes hardware and software design.
 This test bench relate to a reliable test bench of Hybird electric vehicle for drive system. This test bench include of mover, controller of mover, ISG mover, controller of motor, rechargeable battery, managerial system for battery BCM, dynamometer machine and upper controller. This design set forth about the test project design of electric control about Hybird Electric Vehicle. The test project design include of boards for digital information (Hardware) and control soft. Control soft is for output of control signal. Control software is mainly responsible for the output control signals, data for the digital-to-analog converter board to the motor controller control signal output and rotational speed, torque signals into the acquisition and transmission to the control software. Control software at the same time filtering the data and then displayed on the console panel.
 The test bench for evaluating motor drive performance is different from traditional motor test bench. The characteristics of motor drive system have to be considered as well as drive conditions of EV. Accordingly, power and torque measurement tools in the hardware design must satisfy requirements of not only steady performance tests but also dynamic performance tests.
 This test bench can simulate loads on motor shaft when EV is driving on the road and reproduce the process of starting, speed varying and braking. The technology level involved in this test bench has reached an advanced level in the field of EV motor test in China.
