現(xiàn)在汽車已經(jīng)是家家戶戶都擁有的一件交通工具，但是在使用過程中由于各種各樣的原因，不可避免的會(huì)發(fā)生故障，
濟(jì)南寶馬汽車專修小編整理了一些汽車故障診斷方法給您作參考。
Now the automobile is a vehicle owned by every household, but it will inevitably break down due to various reasons in the use process. BMW Jinan has compiled some automobile fault diagnosis methods for your reference.
汽車故障診斷指的是當(dāng)汽車存在故障隱患，技術(shù)狀況變差，或是已經(jīng)部分或完全喪失工作能力，在不解體（或僅卸下個(gè)別小件）條件下，為確定汽車技術(shù)狀況或查明故障部位、原因進(jìn)行的檢測(cè)，以及分析與判斷。
Vehicle fault diagnosis refers to the detection, analysis and judgment for determining the vehicle technical status or finding out the fault location and cause without disassembling (or only removing individual small parts) when the vehicle has potential faults, the technical status has deteriorated, or the vehicle has partially or completely lost its ability to work.
人工診斷法
Artificial diagnosis
人工診斷主要是憑借診斷人員的實(shí)踐經(jīng)驗(yàn)和知識(shí)，借助簡(jiǎn)單工具，用眼看、耳聽、手模等感官手段，邊檢查、邊試驗(yàn)、邊分析，進(jìn)而對(duì)汽車技術(shù)狀況做出判斷。這種方法簡(jiǎn)便直觀，也是建立現(xiàn)代故障診斷專家系統(tǒng)知識(shí)庫的基礎(chǔ)。
Manual diagnosis mainly depends on the practical experience and knowledge of the diagnostic personnel, with the help of simple tools, by means of eyes, ears, hand models and other sensory means, while checking, testing, analyzing, and then making judgments on the technical status of the automobile. This method is simple and intuitive, and it is also the basis of building the knowledge base of modern fault diagnosis expert system.
儀器設(shè)備診斷法
Instrument and equipment diagnosis method
儀器設(shè)備診斷法是采用通用或?qū)Ｓ玫膬x器設(shè)備檢測(cè)汽車、總成和機(jī)構(gòu)，為分析汽車技術(shù)狀況和判斷故障提供定量依據(jù)。一些采用計(jì)算機(jī)控制或配置故障診斷專家系統(tǒng)的儀器設(shè)備可以自動(dòng)完成汽車技術(shù)狀況診斷參數(shù)的測(cè)試、分析、判斷和處理決策。儀器設(shè)備診斷法客觀、定量、檢測(cè)速度快，促進(jìn)了汽車診斷技術(shù)的發(fā)展和應(yīng)用。
Instrument and equipment diagnosis method is to use general or special instruments and equipment to detect automobiles, assemblies and mechanisms, and provide quantitative basis for analyzing automobile technical conditions and judging faults. Some instruments and equipment controlled by computers or equipped with fault diagnosis expert systems can automatically complete the testing, analysis, judgment and processing decisions of the diagnostic parameters of automobile technical conditions. The instrument and equipment diagnostic method is objective, quantitative and fast, which promotes the development and application of automobile diagnostic technology.
在診斷實(shí)踐中，兩種方法往往結(jié)合使用，先是診斷人員向駕駛員詢問故障情況，對(duì)車輛進(jìn)行直觀檢視，憑經(jīng)驗(yàn)初步判斷故障，再利用診斷儀器設(shè)備進(jìn)一步篩選、識(shí)別，終確認(rèn)故障。
In diagnosis practice, the two methods are often used in combination. First, the diagnostic personnel ask the driver about the fault, visually inspect the vehicle, preliminarily judge the fault based on experience, and then use diagnostic instruments and equipment to further screen, identify and finally confirm the fault.
采用相關(guān)技術(shù)的設(shè)備故障分析及預(yù)測(cè)方案，使用數(shù)據(jù)診斷分析，分析故障的規(guī)律，快速找到故障根因，處理設(shè)備故障，避免故障重復(fù)發(fā)生。您對(duì)此有什么想法可以隨時(shí)來我們網(wǎng)站
