機(jī)械外文資料翻譯---abs防抱死系統(tǒng)-文庫吧在線文庫
【正文】 詳細(xì)闡述了車輛 ABS 快速開發(fā)的基本方法和基本過程，即從非在線數(shù)字仿真，實(shí)時數(shù)字仿真，硬件嵌入式實(shí)時混合仿真，以及實(shí)車試驗驗證整個 ABS 研究和開發(fā)過程。 ABS 動 力學(xué)系統(tǒng)模型主要包括整車模型，輪胎神經(jīng)網(wǎng)絡(luò)模型，液壓系統(tǒng)模型以及制動器模型。在 ABS 開發(fā)的初期，由于受計算機(jī)技術(shù)發(fā)展的限制，一般靠大量道路試驗來摸索控制規(guī)律，耗費(fèi)大量人力、物力和財力，開發(fā)周期比較長。軟件完成數(shù)據(jù)的收集和處理通過人機(jī)對話，實(shí)現(xiàn)對該 ABS 性能的檢測和評價。 畢業(yè)設(shè)計 (論文 )外文資料翻譯 學(xué)院 （ 系）： 專 業(yè)： 機(jī)械制造及自動化 姓 名： 學(xué) 號： 外文出處： Business Weekly 附 件： ； 文 指導(dǎo)教師評語： 譯文選題符合畢業(yè)設(shè)計要求，語句基本通順，譯意正確，基本達(dá)到畢業(yè)設(shè)計大綱要求。檢測裝備傳感器安裝在一臺具 有 ABS 的實(shí)驗汽車?yán)锊⒄{(diào)試，完成對車輛行駛各種信息的采集。車輛 ABS 電子控制系統(tǒng)的開發(fā)，涉及到機(jī)械、電子、液壓技術(shù)、計算機(jī)軟硬件開發(fā)，以及試驗技術(shù)等方面。決速開發(fā)系統(tǒng)中的最重要的組成部分，直接關(guān)系到控制器的開發(fā)效率和精度。同時根據(jù)硬件配置的需要，進(jìn)行了接口設(shè)備、驅(qū)動電路和電氣系統(tǒng)的設(shè)計。利用前饋補(bǔ)償和模糊控制技術(shù)，以方向盤轉(zhuǎn)角為前饋輸入變量，車輛橫擺角速度和側(cè)偏角為反饋輸入變量，設(shè)計了車輛橫向穩(wěn)定性控制器。s business environment automotive industries suffer constantly increasing pressure of reduction in the development cost and time of new vehicle electronic products to meet the demands of market and urgent effective approaches to innovation of sophisticated vehicle electronic products. In this paper, a new rapid development method is proposed to develop and test ABS control system efficiently in laboratory environment, which covers the whole process of concept and function design, system modeling, offline simulation, code automatic generation, realtime hardwareintheloop (HiL) simulation and final vehicle test validation. This economical ABS rapid development system characterized by a parallel rather than a serial development process is built up with friendly interface for implementation of the present development procedure. The rapid development system is based on HiL simulation technology, and function of sensors and actuators of the control system are replaced by software to simulate a field test environment in a controllable situation. Therefore, consistently reproducible test conditions are provided and critical safety issues may be solved in the stage of electronic product development prior to invehicle tests. The present rapid development system is successfully employed in the ABS control system development and the developed control algorithm has been validated in the vehicle filed test. According to the test measures, the control precise is close to that of the original one. It is proved that t
