隨(sui)著汽(qi)車工業的不斷發(fa)展，人們(men)對汽(qi)車的性(xing)(xing)能和(he)安全(quan)(quan)性(xing)(xing)要求(qiu)越(yue)來(lai)越(yue)高。汽(qi)車服務商抓住了(le)大眾的心理和(he)需(xu)求(qiu)，在安全(quan)(quan)、環保、舒服三個方面(mian)做了(le)深度優(you)化。現(xian)在汽(qi)車的安全(quan)(quan)性(xing)(xing)要求(qiu)很高，包括主(zhu)動安全(quan)(quan)和(he)被動安全(quan)(quan)，安全(quan)(quan)與汽(qi)車性(xing)(xing)能和(he)檢(jian)測密(mi)切(qie)相(xiang)關。

汽(qi)(qi)車(che)傳統(tong)(tong)的(de)(de)制(zhi)(zhi)(zhi)動(dong)(dong)方式是安裝摩擦(ca)制(zhi)(zhi)(zhi)動(dong)(dong)器，利用滑動(dong)(dong)摩擦(ca)的(de)(de)原理(li)來制(zhi)(zhi)(zhi)動(dong)(dong)汽(qi)(qi)車(che)。汽(qi)(qi)車(che)經過長時間的(de)(de)發(fa)展(zhan)，傳統(tong)(tong)的(de)(de)制(zhi)(zhi)(zhi)動(dong)(dong)方式也發(fa)生(sheng)了(le)很大(da)的(de)(de)變化。目(mu)前制(zhi)(zhi)(zhi)動(dong)(dong)效(xiao)果(guo)好(hao)的(de)(de)很先進的(de)(de)制(zhi)(zhi)(zhi)動(dong)(dong)裝置是防抱死制(zhi)(zhi)(zhi)動(dong)(dong)系(xi)統(tong)(tong)。由(you)于它的(de)(de)存在，汽(qi)(qi)車(che)的(de)(de)制(zhi)(zhi)(zhi)動(dong)(dong)方向(xiang)具有很大(da)的(de)(de)穩定性(xing)，不易發(fa)生(sheng)側滑、跑偏(pian)等事故(gu)。普通制(zhi)(zhi)(zhi)動(dong)(dong)系(xi)統(tong)(tong)突然剎車(che)時，摩擦(ca)力大(da)于汽(qi)(qi)車(che)的(de)(de)動(dong)(dong)力，產生(sheng)靜摩擦(ca)力，導(dao)致汽(qi)(qi)車(che)抱死。防抱死制(zhi)(zhi)(zhi)動(dong)(dong)系(xi)統(tong)(tong)正好(hao)解決了(le)這(zhe)個問題(ti)。

每一個汽(qi)車系(xi)統和設(she)備都有(you)(you)自己獨特的功能(neng)，比如汽(qi)車故障(zhang)診斷設(she)備，可(ke)以(yi)快速診斷出汽(qi)車出了(le)什么問題(ti)。這(zhe)種(zhong)防抱死制動系(xi)統可(ke)以(yi)從根本上提高汽(qi)車的性(xing)能(neng)，還(huan)可(ke)以(yi)改善輪胎(tai)磨(mo)損。它(ta)還(huan)具有(you)(you)很(hen)強(qiang)的舒服性(xing)，駕駛員無需擔心車輪抱死的問題(ti)，從心理上減輕了(le)駕駛員的疲勞，從而保證(zheng)了(le)行車安全。

變(bian)(bian)(bian)(bian)速(su)器(qi)是(shi)控(kong)制車(che)速(su)的(de)重(zhong)要部件。當(dang)車(che)速(su)不(bu)穩定(ding)時(shi)，可以使(shi)用車(che)輛故障(zhang)(zhang)診(zhen)斷設備檢查變(bian)(bian)(bian)(bian)速(su)器(qi)是(shi)否有故障(zhang)(zhang)。變(bian)(bian)(bian)(bian)速(su)器(qi)故障(zhang)(zhang)的(de)原(yuan)因有：變(bian)(bian)(bian)(bian)速(su)器(qi)換擋(dang)、變(bian)(bian)(bian)(bian)速(su)器(qi)缺油或變(bian)(bian)(bian)(bian)速(su)器(qi)油過多等。當(dang)萬向(xiang)傳(chuan)動出(chu)現故障(zhang)(zhang)時(shi)，會(hui)發出(chu)奇怪的(de)噪音(yin)，引起震動，當(dang)我們握著方向(xiang)盤時(shi)，會(hui)感(gan)到手臂麻木(mu)疼痛。
