【正文】 le involves the ABS performance examination, is divided software and the hardware two parts, plements one another pletes the examination together. Equipped the ABS automobile to carry on applies the brake the effect, the ABS performance appraisal and the analysis. Computer based on Visual Basic translation development corresponding application procedure. The examination equipment sensor installs in has ABS in the experimental automobile automobile and debugs, pletes goes each kind of information gathering to the vehicles. Software pletes the data the collection and processing through the manmachine dialogue, realizes to this ABS performance examination and the appraisal. With increase of public interest in vehicle performance of safety, emission and ride fort, vehicle electronic control systems have been developed in generations for the purpose of enhancing overall dynamic behaviors by almost all automakers and parts suppliers for decades. The development of antilock braking system (ABS), for improving vehicle braking and handling performance, involves mechanism electronics, hydraulics, hardware and software design and field test validation, and also requires repeated field tests on various road conditions, which are not easily available. In the very beginning of product development for vehicle ABS, a huge amount of vehicle field tests are required to investigate the control laws by a great number of repeated modifications. Moreover, even in most repeatable test environments, the road conditions for field tests cannot be controlled exactly to be identical. This inevitably leads to increase of both development cost and cycle time for ABS product. Because of fierce petition in today39。文中建立的 ABS 快速開(kāi)發(fā)系統(tǒng)是一個(gè)開(kāi)放式的車輛電子控制系統(tǒng)快速開(kāi)發(fā)平臺(tái)。通過(guò)控制前軸左右車輪制動(dòng)力動(dòng)態(tài)分配，實(shí)現(xiàn)車輛在任何行駛工況下都能按駕駛員意圖跟蹤理想控制目標(biāo)。利用實(shí)車道路試驗(yàn)對(duì) ABS 控制器參數(shù)進(jìn)行精調(diào)，最終完成對(duì) ABS 控制器的快速開(kāi)發(fā)。應(yīng)用建成的這一快速開(kāi)發(fā)系統(tǒng)，詳細(xì)闡述了車輛 ABS 快速開(kāi)發(fā)的基本方法和基本過(guò)程，即從非在線數(shù)字仿真，實(shí)時(shí)數(shù)字仿真，硬件嵌入式實(shí)時(shí)混合仿真，以及實(shí)車試驗(yàn)驗(yàn)證整個(gè) ABS 研究和開(kāi)發(fā)過(guò)程。 基于混合仿真技術(shù)，本文進(jìn)行了車輛 ABS 快速開(kāi)發(fā)系統(tǒng)的總體方案和功能設(shè)計(jì)，并論述了實(shí)時(shí)仿真環(huán)境的實(shí)現(xiàn)方法。 ABS 動(dòng) 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(dòng)器模型。整個(gè)開(kāi)發(fā)過(guò)程包括控制系統(tǒng)概念設(shè)計(jì)，系統(tǒng)建模，系統(tǒng)離線仿真，代碼自動(dòng)生成，硬件在環(huán)實(shí)時(shí)仿真以及最終產(chǎn)品試驗(yàn)。在 ABS 開(kāi)發(fā)的初期，由于受計(jì)算機(jī)技術(shù)發(fā)展的限制，一般靠大量道路試驗(yàn)來(lái)摸索控制規(guī)律，耗費(fèi)大量人力、物力和財(cái)力，開(kāi)發(fā)周期比較長(zhǎng)。作為主動(dòng)安全系統(tǒng)代表車防抱死制動(dòng)系統(tǒng) (ABS) 是在這種背景提出和發(fā)展起來(lái)的。軟件完成數(shù)據(jù)的收集和處理通過(guò)人機(jī)對(duì)話，實(shí)現(xiàn)對(duì)該 ABS 性能的檢測(cè)和評(píng)價(jià)。 本文涉及的 ABS 性能的檢測(cè)，分軟件和硬件兩個(gè)部分，相輔相成共同完成檢測(cè)。 畢業(yè)設(shè)計(jì) (論文 )外文資料翻譯 學(xué)院 （ 系）： 專 業(yè)
