【摘要】 防抱制动系统(ABS)是现代汽车重要的主动安全装置之一。由于涉及到机、电、液一体化的问题,ABS装置的开发难度较大,其控制器的开发更是制约着国内ABS产业的发展。本文试图避开传统的以大量实车道路试验为基础的ABS控制器开发方法,以两台电脑(一台为嵌入式计算机,另一台为工业控制计算机)为平台,通过数据采集卡和MATLAB接口函数连接软、硬件,建立一个ABS控制器嵌入式开发系统,主要成果如下:(1)结合研扬公司的PCM-6890B主板和便携式C164采集卡,建立了一台基于PC/104总线的嵌入式PC;该嵌入式PC和另一台工控机(宿主机)构成了一个嵌入式开发系统;(2)根据ABS系统车辆动力学数学模型建立了车辆和ABS控制器的SIMULINK模型;(3)将车辆模型和ABS控制器模型进行了分离,并置入上述两台电脑中,通过编写接口函数使其和硬件相连,进行硬件在环仿真,方便地修改和优化控制器模型;优化后的SIMULINK控制器模型可由SIMULINK/RTW工具转换为可执行代码,该代码经优化可在目标单片机中运行。采用该系统进行ABS产品的开发,可以减少实车道路试验、缩短开发周期和降低开发成本。该系统对推动汽车ABS产品的国产化进程、提升ABS控制器的自主开发能力,具有一定的科学意义和应用前景,同时,该系统也适合对其他电子设备的开发。更多还原

【Abstract】 The Anti-lock Braking System (ABS) is one of the important active safety devices of modern automobiles. The ABS device is a complicated system and deals with interdisciplinary knowledge such as mechanics, electronics, and hydraulics. The ABS controller technique is a main bottleneck of the ABS development in China.Different from the traditional method, where the development of the ABS controller is based on a mass of vehicle road test, this thesis uses an embedded system. The system is comprised of two PCs, the MATLAB interface function, and some data acquisition cards. One of the PCs is an embedded PC, and the other is an industrial control computer. The main outcomes of this study are as follows:(4) An embedded development system is developed, which consists of an embedded PC and an industrial control computer, the embedded PC is consist of a PCM-6890B main-board and a convenient acquisition card.(5) An ABS controller SIMULINK (an add-in tool of MATLAB) model is developed based on the dynamics model of the vehicle.(6) A hardware-in-the-loop simulation technique is adopted to update and optimize the model parameters. After the model parameters are optimized, the controller model can be transformed into the executable code by using the RTW (an add-in tool of MATLAB). The controller model obtained in such a way is relatively effective and flexible.The developed system can significantly reduce the vehicle road test, shorten the development process, and hence reduce the development cost. In the meantime, the method presented in the thesis can be used in similar situations.更多还原
