概述目(mu)前(qian)(qian)，2轎(jiao)車的(de)(de)4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)裝置已經引進了電(dian)子(zi)計(ji)算機控(kong)制系統(tong)，當前(qian)(qian)輪(lun)或后輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)時(shi)(shi)(shi)，車子(zi)隨時(shi)(shi)(shi)根據路面(mian)狀態的(de)(de)反饋信息分(fen)配前(qian)(qian)后輪(lun)子(zi)的(de)(de)動(dong)(dong)(dong)力，變為4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)。4輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)又(you)可(ke)以細分(fen)成4種(zhong)(zhong)驅(qu)(qu)(qu)動(dong)(dong)(dong)模式：全(quan)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time）、分(fen)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Part-Time）、適時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Real－Time）和分(fen)時(shi)(shi)(shi)/適時(shi)(shi)(shi)混和驅(qu)(qu)(qu)動(dong)(dong)(dong)。全(quan)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)全(quan)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)（Full－Time） 全(quan)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)特點就是(shi)無論怎么樣，永遠(yuan)都保持四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)模式，這種(zhong)(zhong)傳動(dong)(dong)(dong)系統(tong)都是(shi)不需要駕(jia)駛(shi)(shi)人選擇操作(zuo)的(de)(de)。行(xing)駛(shi)(shi)的(de)(de)時(shi)(shi)(shi)將(jiang)發動(dong)(dong)(dong)機輸出扭矩按50∶50 設定(ding)在前(qian)(qian)后輪(lun)上，使(shi)前(qian)(qian)后排(pai)車輪(lun)保持等量的(de)(de)扭矩，遇到特別路面(mian)的(de)(de)時(shi)(shi)(shi)候就可(ke)以自動(dong)(dong)(dong)將(jiang)不同的(de)(de)扭距分(fen)配到各個輪(lun)子(zi)上面(mian)。全(quan)時(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)系統(tong)具有良好的(de)(de)駕(jia)駛(shi)(shi)操控(kong)性(xing)和行(xing)駛(shi)(shi)循跡性(xing)，不過缺點也(ye)是(shi)很明顯的(de)(de)，那(nei)就是(shi)比(bi)較(jiao)廢(fei)油，經濟性(xing)不夠好，而(er)且(qie)車輛沒有任何裝置來(lai)控(kong)制輪(lun)胎(tai)轉速的(de)(de)差異(yi)，一旦一個輪(lun)胎(tai)離開地面(mian)就有可(ke)能讓你無法前(qian)(qian)進。
