摘  要

 电子机械制动系统（EMB，Electro-Mechanical Braking System）以电驱动元件为制动执行器，取代传统的液压或气压制动执行器，是一种全新的制动理念没有制动液体，体积小巧，反应快速，性能可靠，安全环保等特点使 EMB 系统
拥有良好的应用前景和市场价值。
 本文通过设计并搭建一个 EMB 试验台，对 EMB 系统控制及应用进行研究，
为此作了如下几方面的工作：
 1、根据现有的材料，通过设计、计算及选型，加工完成了 EMB 试验台的
机械部件，并基于 IRF250 芯片设计了力矩电机驱动电路。
 2、根据 EMB 试验台的特性和要求，以 PC 为硬件平台，MFC(Microsoft
Foundation Class)为软件平台，基于 NI PCI-6024E 多功能数据采集卡，设计开发了 EMB 试验台软件系统，主要实现实时仿真计算、数据显示、数据存储、界面控制、与采集卡实时通讯等功能。
 3、EMB 试验台特性测试及应用，首先实现了实时获取驾驶员制动意图，根
据制动踏板位移线性控制力矩电机输出力矩的功能，随后采用 PID 控制算法，通过半物理仿真，实现了 EMB 系统对汽车的防侧翻功能。
 通过上述研究，本文完成了 EMB 试验台的开发，为进一步深入研究 EMB系统控制算法及性能提供了很好的实验平台。

ABSTRACT
 
 The Electro-Mechanical Braking System (EMB), which takes the place of conventional brake actuator-liquid or air pressure, is a new conception of braking system. The advantages such as no brake fluid, desponding quickly, reliable capability, safe and propitious to environment protecting give EMB an exciting future and market value.
 In order to research the control strategy and algorithm and the application of EMB system, a test-rig was established. For these, the following points were finished in this thesis:
 1, Based on the available materials, the mechanical parts of the EMB test-rig were designed and machined, and also a driving circuit consist of an integrate circuit -- IRF250 to the torque motor was designed.  
 2, The software system of the host computer suitable for the EMB test-rig was designed and developed based on a NI PCI-6024E multifunction DAQ card. With the PC serving as hardware platform, the MFC (Microsoft Foundation Class) as the software platform, the software system communicates with he NI PCI-6024E multifunction DAQ card through the PCI bus. Its main functions are real-time simulation calculating, displaying and storing the datam controlling the equipment throngh the interface and communicating with the multifunction DAQ card.
 3, By testing on the EMB test-rig, the function was achieved that acquiring the
real-time brake desire of driver to control the motor torque in linearity rule according
to the displacement of brake pedal. And then the rollover control function to a vehicle
was actualized with the EMB test-rig by using PID control.
 The EMB test-rig has been built up, which lays solid foundation for further researching on the characteristics and control algorithm of the EMB system.
