【正文】 本科畢業(yè)論文 題目名稱： 常用的汽車電子控制系統(tǒng) 故障診斷方法的研究 學(xué) 院： 專業(yè)年級： 學(xué)生姓名： 班級學(xué)號： 指導(dǎo)教師： 二 XXX 年 六 月 十 日 摘要 I 摘 要 隨著汽車工業(yè)的發(fā)展，電子控制技術(shù)在現(xiàn)代汽車上的應(yīng)用越來越廣泛，但是汽車電子控制系統(tǒng)故障也遠 比傳 統(tǒng)汽車故障復(fù)雜得多，這給故障診斷和維修工作增加了困難。本文通過對 常用的汽車電子控制系統(tǒng)故障診斷方法的研究， 把 對各診斷方法適用的故障類型進行了簡單的歸納總結(jié)，使發(fā)生在汽車電子控制系統(tǒng)中的各 種故障類 型與診斷方法基本對應(yīng)，避免了以后診斷工作時的盲目性。結(jié)合現(xiàn)代社會和科學(xué)技術(shù)的發(fā)展對汽車電子控制系統(tǒng)故障診斷方法的發(fā)展加以展望，闡述了汽車電子控制系統(tǒng)故障診斷的趨勢。 關(guān)鍵詞 ： 電子控制系統(tǒng) 故障診斷 診斷方法 大學(xué)本科畢業(yè)論文 II Abstract With the development of the automotive industry, the application of electronic control technology on modern cars is more and more extensive, but troubles with electronic control system are far more plex than the traditional car failure, which give more difficulties to the diagnosis and maintenance work of troubles. Based on the research of monly used automotive electronic control system fault diagnosis methods, this paper has simply summarized diagnostic methods applicable to all types of fault. It will make various types of fault which occurs in automotive electronic control systems correspond to diagnostic methods, and avoid the work of the blindness in the after diagnosis. Combined with modern social and development of scientific technological, the development of the method for automotive electronic control system fault diagnosis is prospected, indicate the trend of automotive electronic control system fault diagnosis. Keywords: Electronic control system， Trouble diagnosis， Diagnosis method Abstract I 目錄 摘 要 ...........................................................................................................................................
