摘  要

 電子機(jī)械制動系統(tǒng)（EMB，Electro-Mechanical Braking System）以電驅(qū)動元件為制動執(zhí)行器，取代傳統(tǒng)的液壓或氣壓制動執(zhí)行器，是一種全新的制動理念沒有制動液體，體積小巧，反應(yīng)快速，性能可靠，安全環(huán)保等特點使 EMB 系統(tǒng)
擁有良好的應(yīng)用前景和市場價值。
 本文通過設(shè)計并搭建一個 EMB 試驗臺，對 EMB 系統(tǒng)控制及應(yīng)用進(jìn)行研究，
為此作了如下幾方面的工作：
 1、根據(jù)現(xiàn)有的材料，通過設(shè)計、計算及選型，加工完成了 EMB 試驗臺的
機(jī)械部件，并基于 IRF250 芯片設(shè)計了力矩電機(jī)驅(qū)動電路。
 2、根據(jù) EMB 試驗臺的特性和要求，以 PC 為硬件平臺，MFC(Microsoft
Foundation Class)為軟件平臺，基于 NI PCI-6024E 多功能數(shù)據(jù)采集卡，設(shè)計開發(fā)了 EMB 試驗臺軟件系統(tǒng)，主要實現(xiàn)實時仿真計算、數(shù)據(jù)顯示、數(shù)據(jù)存儲、界面控制、與采集卡實時通訊等功能。
 3、EMB 試驗臺特性測試及應(yīng)用，首先實現(xiàn)了實時獲取駕駛員制動意圖，根
據(jù)制動踏板位移線性控制力矩電機(jī)輸出力矩的功能，隨后采用 PID 控制算法，通過半物理仿真，實現(xiàn)了 EMB 系統(tǒng)對汽車的防側(cè)翻功能。
 通過上述研究，本文完成了 EMB 試驗臺的開發(fā)，為進(jìn)一步深入研究 EMB系統(tǒng)控制算法及性能提供了很好的實驗平臺。

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.
