適(shi)(shi)(shi)時(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)適(shi)(shi)(shi)時(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)介(jie)乎全(quan)時(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)分時(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)之間，驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式由電腦安(an)排，操(cao)縱(zong)非常簡單。采(cai)用這種驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)系(xi)統的(de)車(che)輛時(shi)根(gen)據(ju)電腦來控制并(bing)且選(xuan)擇(ze)適(shi)(shi)(shi)合當下(xia)情況(kuang)的(de)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式。在正常的(de)路(lu)面上(shang)車(che)輛一(yi)般(ban)會(hui)采(cai)用后輪(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)方式，而(er)一(yi)旦(dan)遇到路(lu)面不良或驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)輪(lun)打滑的(de)情況(kuang)，電腦就(jiu)會(hui)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)檢(jian)測并(bing)立即(ji)將發動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)輸(shu)出扭矩分配給前排的(de)兩個車(che)輪(lun)，自(zi)然(ran)切(qie)(qie)換到四輪(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)狀態(tai)，從而(er)免除(chu)了駕(jia)駛人的(de)判斷和(he)手(shou)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)作，應用更加簡單。不過以目(mu)前的(de)效果來看，電腦比起人腦速度(du)還是慢了很多，也就(jiu)是說住往(wang)不能及時(shi)進行驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)模(mo)式的(de)切(qie)(qie)換，反應較慢。比如北(bei)京(jing)現代生產的(de)途(tu)勝就(jiu)是采(cai)用適(shi)(shi)(shi)時(shi)四驅(qu)設(she)計。

汽(qi)(qi)車(che)在行(xing)(xing)駛(shi)(shi)時，電腦利用(yong)下述3種傳(chuan)(chuan)(chuan)感器不(bu)斷(duan)檢測汽(qi)(qi)車(che)的(de)行(xing)(xing)駛(shi)(shi)狀態，即4個車(che)輪的(de)轉(zhuan)(zhuan)速傳(chuan)(chuan)(chuan)感器、汽(qi)(qi)車(che)的(de)前(qian)(qian)(qian)(qian)后(hou)左右加速度傳(chuan)(chuan)(chuan)感器、發動(dong)機轉(zhuan)(zhuan)速傳(chuan)(chuan)(chuan)感器。此外，利用(yong)轉(zhuan)(zhuan)向盤轉(zhuan)(zhuan)向角傳(chuan)(chuan)(chuan)感器、油(you)門(men)踏板(ban)開度傳(chuan)(chuan)(chuan)感器不(bu)斷(duan)地判斷(duan)司機的(de)駕(jia)駛(shi)(shi)意圖(tu)，按(an)預先給定的(de)程(cheng)序(xu)進行(xing)(xing)綜合(he)控制。在AWD系統(tong)中，向前(qian)(qian)(qian)(qian)后(hou)車(che)輪的(de)動(dong)力(li)(li)(li)分(fen)配影(ying)響到(dao)汽(qi)(qi)車(che)的(de)行(xing)(xing)駛(shi)(shi)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)。如當汽(qi)(qi)車(che)向前(qian)(qian)(qian)(qian)后(hou)輪驅(qu)(qu)動(dong)力(li)(li)(li)的(de)分(fen)配比為(wei)0:100時，具有較(jiao)高的(de)轉(zhuan)(zhuan)向性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)和(he)極限行(xing)(xing)駛(shi)(shi)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)，當驅(qu)(qu)動(dong)力(li)(li)(li)分(fen)配比為(wei)50:50時，穩(wen)定性(xing)(xing)(xing)(xing)(xing)得(de)到(dao)提高，但轉(zhuan)(zhuan)向性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)和(he) 極限行(xing)(xing)駛(shi)(shi)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)會下降(jiang)。在轉(zhuan)(zhuan)向性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)、穩(wen)定性(xing)(xing)(xing)(xing)(xing)和(he)極限行(xing)(xing)駛(shi)(shi)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)之間(jian)要(yao)獲得(de)良好平衡(heng)，必須確定優的(de)前(qian)(qian)(qian)(qian)后(hou)驅(qu)(qu)動(dong)力(li)(li)(li)分(fen)配系數，理想的(de)分(fen)配系數按(an)照不(bu)同(tong)的(de)路面(mian)(mian)有所不(bu)同(tong)，在允(yun)許強力(li)(li)(li)加速的(de)鋪裝(zhuang)路面(mian)(mian)上考慮到(dao)載荷轉(zhuan)(zhuan)移(yi)，以向后(hou)輪分(fen)配較(jiao)大(da)驅(qu)(qu)動(dong)力(li)(li)(li)為(wei)宜。但是(shi)，在打(da)滑的(de)路面(mian)(mian)，當向后(hou)輪分(fen)配較(jiao)大(da)驅(qu)(qu)動(dong)力(li)(li)(li)時，就會引起(qi)過度轉(zhuan)(zhuan)向。有資料(liao)認(ren)為(wei)，理想的(de)前(qian)(qian)(qian)(qian)后(hou)驅(qu)(qu)動(dong)力(li)(li)(li)分(fen)配比在3O ：70～50：50。目前(qian)(qian)(qian)(qian)，本田新(xin)一代Legend轎車(che)的(de)SH—AWD能(neng)(neng)(neng)使前(qian)(qian)(qian)(qian)后(hou)驅(qu)(qu)動(dong)力(li)(li)(li)分(fen)配在70：30—30：70內連續變(bian)化。
