汽車電路故障判斷技巧:常見故障的原因

來源:http://www.nhakhoathuduc.net/ 日期:2021-08-26 發(fā)布人:admin
常見的故障原因有:1、維修不專業(yè)導(dǎo)致故障,2、私自加裝電器引起線路故障,3、人為操作不當(dāng)引起故障,4、洗車不當(dāng)造成問題,5、缺乏保養(yǎng)引起故障
Common fault causes include: 1. Failure caused by unprofessional maintenance; 2. Line failure caused by unauthorized installation of electrical appliances; 3. Failure caused by improper human operation; 4. Problems caused by improper car washing; 5. Failure caused by lack of maintenance
1)汽車電子從結(jié)構(gòu)上分為傳感器、控制單元、執(zhí)行器、連接導(dǎo)線/數(shù)據(jù)線四大部分,汽車電子故障也與這四個方面的正常運(yùn)行情況有著很密切的關(guān)系。汽車電子構(gòu)造中這些部件都是很精 密的,對于使用環(huán)境也有著較高的要求,而目前車主普遍存在的對電子部件缺乏保養(yǎng)、清潔不到位已成為造成故障的重要原因。
1) The structure of automotive electronics is divided into four parts: sensor, control unit, actuator and connecting wire / data line. The fault of automotive electronics is also closely related to the normal operation of these four aspects. These components in the automotive electronic structure are very precise and have high requirements for the use environment. At present, the lack of maintenance and poor cleaning of electronic components, which are common among car owners, has become an important cause of failure.
2)汽車傳感器傳感器作為汽車電子控制系統(tǒng)的信息源,是汽車電子控制系統(tǒng)的關(guān)鍵部件,而它如果受到灰塵等雜物的污染,就可能造成傳感器的靈敏度和精 密度降低,甚至?xí)霈F(xiàn)傳感信號失真,從而使得車輛控制單元和執(zhí)行器出現(xiàn)故障而無 法正常行駛。
2) As the information source of the automobile electronic control system, the automobile sensor is the key component of the automobile electronic control system. If it is polluted by dust and other sundries, it may reduce the sensitivity and precision of the sensor, and even cause the distortion of the sensing signal, resulting in the failure of the vehicle control unit and actuator.
3)連接導(dǎo)線采用電子儀表的汽車,需要很多連接器把電線束連到儀表板上去。然而這些連接器一旦受潮或被水侵蝕后,往往會使連接導(dǎo)線氧化,進(jìn)而導(dǎo)致接觸不好。檢查時可用眼看或手摸的方法進(jìn)行,連接器裝置要齊全、完好,插頭、插座應(yīng)接觸可靠、無銹蝕。儀表電路工作中用手觸摸連接器,應(yīng)沒有明顯的溫度感覺,若溫度過高,說明該連接器接觸不好 ,應(yīng)查明原因予以排除。
3) Cars with electronic instruments need many connectors to connect the wire harness to the instrument panel. However, once these connectors are damp or eroded by water, they often oxidize the connecting wires, resulting in poor contact. The inspection can be carried out by eye or hand. The connector device shall be complete and intact, and the plug and socket shall be contacted reliably without corrosion. When touching the connector by hand during the operation of instrument circuit, there shall be no obvious temperature feeling. If the temperature is too high, it indicates that the connector is not in good contact, and the cause shall be found out and eliminated.
以上就是小編給大家介紹的關(guān)于汽車電路故障判斷技巧的全部內(nèi)容了。看完小編的介紹以后,大家有沒有對汽車電路故障判斷技巧有一個基本的了解呢,好了今天小編就先介紹到這里,要想了解更多咨詢,就來關(guān)注陸通汽車吧。
