概(gai)述目(mu)前(qian)(qian)(qian)，2轎車的(de)(de)(de)4輪驅(qu)(qu)(qu)動(dong)(dong)(dong)裝(zhuang)置(zhi)已(yi)經引進了電子(zi)計算機控制(zhi)系統(tong)(tong)，當前(qian)(qian)(qian)輪或后輪驅(qu)(qu)(qu)動(dong)(dong)(dong)時(shi)，車子(zi)隨時(shi)根據路面(mian)狀態的(de)(de)(de)反饋信(xin)息分(fen)(fen)配前(qian)(qian)(qian)后輪子(zi)的(de)(de)(de)動(dong)(dong)(dong)力，變為4輪驅(qu)(qu)(qu)動(dong)(dong)(dong)。4輪驅(qu)(qu)(qu)動(dong)(dong)(dong)又可(ke)以細分(fen)(fen)成4種(zhong)驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)：全(quan)(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time）、分(fen)(fen)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Part-Time）、適時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Real－Time）和分(fen)(fen)時(shi)/適時(shi)混和驅(qu)(qu)(qu)動(dong)(dong)(dong)。全(quan)(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)全(quan)(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time） 全(quan)(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)特點就是無(wu)論(lun)怎(zen)么(me)樣，永遠都保持四輪驅(qu)(qu)(qu)動(dong)(dong)(dong)模(mo)式(shi)，這(zhe)種(zhong)傳動(dong)(dong)(dong)系統(tong)(tong)都是不(bu)需要駕駛人選(xuan)擇操作的(de)(de)(de)。行(xing)駛的(de)(de)(de)時(shi)將發(fa)動(dong)(dong)(dong)機輸(shu)出扭(niu)(niu)矩按(an)50∶50 設定在前(qian)(qian)(qian)后輪上(shang)，使(shi)前(qian)(qian)(qian)后排車輪保持等(deng)量的(de)(de)(de)扭(niu)(niu)矩，遇(yu)到特別路面(mian)的(de)(de)(de)時(shi)候就可(ke)以自(zi)動(dong)(dong)(dong)將不(bu)同(tong)的(de)(de)(de)扭(niu)(niu)距分(fen)(fen)配到各個輪子(zi)上(shang)面(mian)。全(quan)(quan)時(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)系統(tong)(tong)具有(you)良好的(de)(de)(de)駕駛操控性(xing)和行(xing)駛循跡性(xing)，不(bu)過缺(que)點也是很明顯的(de)(de)(de)，那就是比較廢油，經濟性(xing)不(bu)夠好，而且車輛沒(mei)有(you)任何裝(zhuang)置(zhi)來(lai)控制(zhi)輪胎轉速的(de)(de)(de)差異，一(yi)旦一(yi)個輪胎離開地面(mian)就有(you)可(ke)能(neng)讓你無(wu)法前(qian)(qian)(qian)進。

四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)（4 Wheel Drive)主變(bian)(bian)(bian)速器(qi)通(tong)(tong)過一(yi)個輔(fu)助(zhu)變(bian)(bian)(bian)速器(qi)將動(dong)(dong)(dong)(dong)力傳(chuan)送到前輪(lun)(lun)(lun)和(he)后輪(lun)(lun)(lun). 輔(fu)助(zhu)變(bian)(bian)(bian)速器(qi)通(tong)(tong)常(chang)(chang)有三檔選擇(ze)(ze)； 空(kong)檔，四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)，四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)低檔。空(kong)檔時，四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)就變(bian)(bian)(bian)成(cheng)了兩輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)。四(si)輪(lun)(lun)(lun)驅(qu) 動(dong)(dong)(dong)(dong)適合(he)于(yu)(yu)惡劣的(de)路(lu)面駕(jia)(jia)駛(shi)，例(li)如，雨雪天和(he)多(duo)沙石(shi)路(lu)面。四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)低檔則適合(he)高難度的(de)越(yue)野駕(jia)(jia)駛(shi)。全輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong) (All Wheel Drive)全輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)是(shi)四(si)輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)的(de)一(yi)種. 它(ta)自動(dong)(dong)(dong)(dong)將發動(dong)(dong)(dong)(dong) 機提供的(de) 扭矩(ju)分送到前輪(lun)(lun)(lun)和(he)后輪(lun)(lun)(lun)，不(bu)需要手動(dong)(dong)(dong)(dong)去調整，也沒有低檔選擇(ze)(ze)。全輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong) 減低了車輪(lun)(lun)(lun)打滑的(de)程度，改善了駕(jia)(jia)駛(shi)者的(de)控車能(neng)力。全輪(lun)(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)通(tong)(tong)常(chang)(chang)是(shi)一(yi)種 正(zheng)常(chang)(chang)路(lu)面駕(jia)(jia)駛(shi)系(xi)統，并(bing)不(bu)設計用于(yu)(yu)越(yue)野駕(jia)(jia)駛(shi)。
