現在汽車已經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，不可避免的會發生故障，
濟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汽車存在故障隱患，技術狀況變差，或是已經部分或完全喪失工作能力，在不解體（或僅卸下個別小件）條件下，為確定汽車技術狀況或查明故障部位、原因進行的檢測，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踐經驗和知識，借助簡單工具，用眼看、耳聽、手模等感官手段，邊檢查、邊試驗、邊分析，進而對汽車技術狀況做出判斷。這種方法簡便直觀，也是建立現代故障診斷專家系統知識庫的基礎。
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.
儀器設備診斷法
Instrument and equipment diagnosis method
儀器設備診斷法是采用通用或專用的儀器設備檢測汽車、總成和機構，為分析汽車技術狀況和判斷故障提供定量依據。一些采用計算機控制或配置故障診斷專家系統的儀器設備可以自動完成汽車技術狀況診斷參數的測試、分析、判斷和處理決策。儀器設備診斷法客觀、定量、檢測速度快，促進了汽車診斷技術的發展和應用。
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.
在診斷實踐中，兩種方法往往結合使用，先是診斷人員向駕駛員詢問故障情況，對車輛進行直觀檢視，憑經驗初步判斷故障，再利用診斷儀器設備進一步篩選、識別，終確認故障。
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.
The equipment fault analysis and prediction scheme based on relevant technologies shall be adopted, and the data diagnosis and analysis shall be used to analyze the rule of the fault, so as to quickly find the root cause of the fault, deal with the equipment fault and avoid the repeated occurrence of the fault.
