【正文】 度的模擬實(shí)際車輛在各種工況下的運(yùn)行狀態(tài)，在實(shí)驗(yàn)室條件下實(shí)現(xiàn)對(duì) ABS 控制系統(tǒng)的快速開發(fā)。由于開發(fā)平臺(tái)是統(tǒng)一的，各個(gè)開發(fā)階段之間緊密相連，實(shí)現(xiàn)交互式的并行交流，大大克服了多余的中間環(huán)節(jié)，節(jié)約了時(shí)間和成本。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。對(duì)輪胎神經(jīng)網(wǎng)絡(luò)模型的深入研究，為獲得輪胎神經(jīng)網(wǎng)絡(luò)模型學(xué)習(xí)樣本的實(shí)車試驗(yàn)方案做出了貢獻(xiàn)，并進(jìn)行了相應(yīng)的試驗(yàn)。所有試驗(yàn)結(jié)果都表明，文中建立的 ABS 動(dòng)力學(xué)系統(tǒng)模型理論上是正確的，基本滿足仿真精度要求及后繼研究工作需要。以總體方案設(shè)計(jì)為指導(dǎo)，以 ABS 快速開發(fā)系統(tǒng)功能設(shè)計(jì)為目標(biāo)，從軟件、硬件和接口三個(gè)方面詳細(xì)論述了車輛 ABS 快速開發(fā)系統(tǒng)的設(shè)計(jì)和構(gòu)造。同時(shí)根據(jù)硬件配置的需要，進(jìn)行了接口設(shè)備、驅(qū)動(dòng)電路和電氣系統(tǒng)的設(shè)計(jì)。 以車輛 ABS 邏輯門限值控制方法研究與控制系統(tǒng)開發(fā)為主要目標(biāo)，利用該車輛 ABS 快速開發(fā)系統(tǒng)，對(duì) ABS 實(shí)用化控制邏輯進(jìn)行了全面研究和系統(tǒng)開發(fā)，包括 ABS 控制變量的實(shí)用化算法設(shè)計(jì)， ABS 邏輯門限值實(shí)時(shí)控制算法設(shè)計(jì)。為了驗(yàn)證自行開發(fā)的 ABS 控制器的有效性和實(shí)用性，文中進(jìn)一步闡述了實(shí)車 ABS 的道路試驗(yàn)。實(shí)車道路試驗(yàn)結(jié)果表 明，自行開發(fā)的 ABS 控制器控制有效，運(yùn)行穩(wěn)定，達(dá)到國(guó)外同類產(chǎn)品的控制精度和效果。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(jì)了車輛橫向穩(wěn)定性控制器。以變道工況和高速轉(zhuǎn)向工況為例，進(jìn)行了車輛橫向穩(wěn)定性控制的實(shí)時(shí)混合仿真研究。即使在道路條件和行駛條件改變時(shí)，該控制器對(duì)參數(shù)非線性和不確定性具有較強(qiáng)的適應(yīng)性和魯棒性。 車輛 ABS 快速開發(fā)方法及其系統(tǒng)在 ABS 控制器開發(fā)中的成功應(yīng)用，有力地證明了本文的研究工作使在投入少和周期短的情況下開發(fā)出合格的汽車 ABS 電子產(chǎn)品成為可能。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
