轎車(che)(che)(che)AWD系(xi)統(tong)實際上是驅動力分配(pei)控(kong)(kong)(kong)(kong)制(zhi)方式的(de)(de)四(si)輪(lun)驅動，它利用電(dian)腦(nao)和(he)各種(zhong)不斷改進的(de)(de)傳感(gan)器，不斷判斷輪(lun)胎(tai)對(dui)地 面的(de)(de)動態(tai)附著(zhu)力和(he)司(si)機的(de)(de)駕(jia)駛意圖，積極控(kong)(kong)(kong)(kong)制(zhi)汽(qi)車(che)(che)(che)差速器的(de)(de)差動狀態(tai)，平衡各輪(lun)的(de)(de)驅動力，優(you)化汽(qi)車(che)(che)(che)的(de)(de)各項性能。典型的(de)(de)轎車(che)(che)(che)AWD系(xi)統(tong)主要由前后輪(lun)驅動裝置(zhi)、傳感(gan)器、電(dian)控(kong)(kong)(kong)(kong)單元、分動器和(he)液(ye)壓裝置(zhi)等組成(cheng)。控(kong)(kong)(kong)(kong)制(zhi)系(xi)統(tong)的(de)(de)控(kong)(kong)(kong)(kong)制(zhi)原(yuan)理，在前后輪(lun)之(zhi)問布(bu)置(zhi)一(yi)個濕式多(duo)片離合器，在汽(qi)車(che)(che)(che)行(xing)駛過(guo)程中，使用電(dian)腦(nao)控(kong)(kong)(kong)(kong)制(zhi)液(ye)壓系(xi)統(tong)的(de)(de)油壓，適應汽(qi)車(che)(che)(che)的(de)(de)行(xing) 駛狀態(tai)將驅動扭矩分配(pei)到前后車(che)(che)(che)輪(lun)上去。

分(fen)(fen)(fen)動(dong)器(qi)(qi)(qi)的(de)功能是執行前后(hou)輪扭矩分(fen)(fen)(fen)配功能，在(zai)分(fen)(fen)(fen)動(dong)器(qi)(qi)(qi)中(zhong)間布置一(yi)個濕式多片離合器(qi)(qi)(qi)，該離合器(qi)(qi)(qi)右端通過傳動(dong)軸驅動(dong)后(hou)輪，左端通過鏈傳動(dong)驅動(dong)前輪。電控(kong)(kong)(kong)(kong)(kong)單元(yuan)（ECU)ECU是AWD系統(tong)(tong)的(de)核心，其功用是根據制(zhi)(zhi)定(ding)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)方案，按照(zhao)編(bian)制(zhi)(zhi)的(de)程序對各種傳感器(qi)(qi)(qi)輸入(ru)信(xin)(xin)號進行分(fen)(fen)(fen)析、計算、處理，輸出一(yi)定(ding)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)信(xin)(xin)號指(zhi)令，驅動(dong)電磁閥(fa)動(dong)作(zuo)。AWD系統(tong)(tong)ECU主要(yao)由輸入(ru)信(xin)(xin)號調理電路、微處理器(qi)(qi)(qi)、輸出信(xin)(xin)號處理電路、電源電路等硬件(jian)部分(fen)(fen)(fen)以及控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)(tong)和控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)程序、軟件(jian)平(ping)臺等軟件(jian)部分(fen)(fen)(fen)組成。為保證控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)系統(tong)(tong)可靠地工(gong)作(zuo)，電控(kong)(kong)(kong)(kong)(kong)單元(yuan)還必須采取有(you)效的(de)抗干擾措施和故(gu)障自(zi)診斷(duan)處理措施。

四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)（4 Wheel Drive)主變速器通(tong)(tong)過一(yi)個輔(fu)助(zhu)(zhu)變速器將動(dong)(dong)(dong)(dong)力傳送到(dao)前(qian)輪(lun)(lun)(lun)(lun)和(he)后(hou)輪(lun)(lun)(lun)(lun). 輔(fu)助(zhu)(zhu)變速器通(tong)(tong)常有(you)(you)三(san)檔選擇； 空檔，四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)，四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)低(di)(di)檔。空檔時，四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)就(jiu)變成了(le)(le)兩輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)。四輪(lun)(lun)(lun)(lun)驅(qu)(qu) 動(dong)(dong)(dong)(dong)適(shi)合于惡劣(lie)的(de)路面駕(jia)駛(shi)(shi)，例(li)如，雨雪天(tian)和(he)多沙石路面。四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)低(di)(di)檔則(ze)適(shi)合高(gao)難度(du)的(de)越(yue)野(ye)駕(jia)駛(shi)(shi)。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)是四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)一(yi)種. 它自動(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong) 機提供的(de) 扭矩分送到(dao)前(qian)輪(lun)(lun)(lun)(lun)和(he)后(hou)輪(lun)(lun)(lun)(lun)，不需要手動(dong)(dong)(dong)(dong)去調整(zheng)，也沒有(you)(you)低(di)(di)檔選擇。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong) 減低(di)(di)了(le)(le)車輪(lun)(lun)(lun)(lun)打滑的(de)程(cheng)度(du)，改(gai)善了(le)(le)駕(jia)駛(shi)(shi)者的(de)控車能力。全輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)通(tong)(tong)常是一(yi)種 正常路面駕(jia)駛(shi)(shi)系統，并不設(she)計用于越(yue)野(ye)駕(jia)駛(shi)(shi)。
