一、油電混合車是燒油還是燒電

油電混動車以用(yong)油(you)為(wei)主，沒油(you)可用(yong)電(dian)(dian)(dian)。油(you)電(dian)(dian)(dian)混合(he)動(dong)力汽車，即采用(yong)傳(chuan)統(tong)的(de)(de)內燃機（柴油(you)機或汽油(you)機）和電(dian)(dian)(dian)動(dong)機作(zuo)為(wei)動(dong)力源，車輛(liang)的(de)(de)行(xing)(xing)駛功率依(yi)據實際的(de)(de)車輛(liang)行(xing)(xing)駛狀態由單(dan)個驅(qu)動(dong)系統(tong)單(dan)獨或共(gong)同提供。

油電(dian)混(hun)動(dong)(dong)車最大的特點就是(shi)(shi)以(yi)油為主(zhu)，以(yi)電(dian)動(dong)(dong)機為輔提(ti)供動(dong)(dong)力，值(zhi)得注(zhu)意的是(shi)(shi)這種(zhong)車并不需(xu)要充電(dian)，它巧(qiao)妙的協(xie)調了發動(dong)(dong)機與電(dian)動(dong)(dong)機的工作時機，而且兩者動(dong)(dong)力切換的時候非常平滑自然。

插(cha)電混(hun)動(dong)車(che)和油電混(hun)動(dong)車(che)有很大的區別，插(cha)電混(hun)動(dong)在使用(yong)的時(shi)候是(shi)有電用(yong)電，沒電用(yong)油的方式，需(xu)要注意(yi)的是(shi)，插(cha)電混(hun)動(dong)車(che)如果電量用(yong)完(wan)了的話必須找充(chong)電樁才能充(chong)電，并不(bu)能用(yong)燃油發動(dong)機(ji)直(zhi)接提供充(chong)電，在目前(qian)充(chong)電樁布局(ju)不(bu)算多的情況下(xia)還是(shi)比較(jiao)麻(ma)煩的。當(dang)然這種混(hun)動(dong)車(che)也有一(yi)個(ge)好處就是(shi)在需(xu)要的時(shi)候可以發動(dong)機(ji)和電動(dong)機(ji)一(yi)起工作(zuo)，為車(che)子提供更強的動(dong)力。

增程式混動(dong)車主要由發動(dong)機來(lai)(lai)提(ti)(ti)供動(dong)力，但它依然(ran)可(ke)以(yi)加油，不(bu)過它加的油并不(bu)是用(yong)來(lai)(lai)提(ti)(ti)供動(dong)力的，而是被發動(dong)機用(yong)來(lai)(lai)為電(dian)動(dong)機提(ti)(ti)供電(dian)量，當(dang)然(ran)它也可(ke)以(yi)直(zhi)接在充電(dian)樁進行充電(dian)。

二、油電混合車怎么切換動力

油(you)電混合(he)車(che)是沒有手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)換操作的(de)(de)，油(you)電混合(he)車(che)是由(you)行車(che)電腦來控(kong)制(zhi)的(de)(de)切(qie)(qie)換，并沒有手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)換操作的(de)(de)功能。油(you)電混合(he)車(che)根據車(che)輛在(zai)不同(tong)行駛路(lu)況下的(de)(de)動(dong)(dong)(dong)(dong)力(li)需(xu)求，行車(che)電腦會控(kong)制(zhi)動(dong)(dong)(dong)(dong)力(li)在(zai)電動(dong)(dong)(dong)(dong)機驅(qu)動(dong)(dong)(dong)(dong)、發動(dong)(dong)(dong)(dong)機驅(qu)動(dong)(dong)(dong)(dong)、電動(dong)(dong)(dong)(dong)和發動(dong)(dong)(dong)(dong)機同(tong)時(shi)驅(qu)動(dong)(dong)(dong)(dong)，這三種不同(tong)驅(qu)動(dong)(dong)(dong)(dong)模式下的(de)(de)自動(dong)(dong)(dong)(dong)切(qie)(qie)換，實現不同(tong)動(dong)(dong)(dong)(dong)力(li)的(de)(de)輸出，無需(xu)手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)換。

只是，油電(dian)(dian)混合汽車(che)(che)把(ba)電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機和發動(dong)(dong)(dong)(dong)(dong)機分(fen)為了幾種(zhong)不同的驅動(dong)(dong)(dong)(dong)(dong)模式，在低速(su)巡航時，主要由電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機來驅動(dong)(dong)(dong)(dong)(dong)車(che)(che)輛，不需(xu)要發動(dong)(dong)(dong)(dong)(dong)機的介入，此時車(che)(che)輛動(dong)(dong)(dong)(dong)(dong)力來自于電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機，為電(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機驅動(dong)(dong)(dong)(dong)(dong)模式。

在車(che)輛(liang)需要動(dong)力增(zeng)加，比如提(ti)速(su)時(shi)(shi)，或(huo)者車(che)載(zai)電(dian)池電(dian)量不足時(shi)(shi)，此時(shi)(shi)發(fa)動(dong)機會(hui)及時(shi)(shi)的(de)介入，提(ti)供動(dong)力，保障車(che)輛(liang)的(de)正常行駛。發(fa)動(dong)機在提(ti)供動(dong)力的(de)同時(shi)(shi)，也(ye)同時(shi)(shi)會(hui)給車(che)載(zai)電(dian)池充電(dian)，此時(shi)(shi)，就(jiu)是(shi)發(fa)動(dong)機的(de)驅動(dong)模式。

在(zai)車輛(liang)高速巡(xun)航時(shi)，電(dian)動(dong)(dong)(dong)(dong)機(ji)提(ti)供動(dong)(dong)(dong)(dong)力，不足(zu)(zu)以滿足(zu)(zu)高速巡(xun)航時(shi)車輛(liang)的(de)動(dong)(dong)(dong)(dong)力要(yao)求，此時(shi)，發動(dong)(dong)(dong)(dong)機(ji)就會加入到車輛(liang)的(de)動(dong)(dong)(dong)(dong)力輸出中來，保(bao)障足(zu)(zu)夠的(de)動(dong)(dong)(dong)(dong)力輸出。此時(shi)，車輛(liang)的(de)動(dong)(dong)(dong)(dong)力就由電(dian)動(dong)(dong)(dong)(dong)機(ji)和(he)(he)發動(dong)(dong)(dong)(dong)機(ji)同時(shi)提(ti)供，為電(dian)動(dong)(dong)(dong)(dong)和(he)(he)發動(dong)(dong)(dong)(dong)機(ji)同時(shi)驅動(dong)(dong)(dong)(dong)的(de)模式。

這三種模式的切換(huan)，是(shi)根(gen)據(ju)車(che)輛動力(li)的需求，通過(guo)行車(che)電腦的數據(ju)收集判斷，及(ji)時(shi)地給出指令而實現的。不需要(yao)我們手(shou)動去切換(huan)，手(shou)動切換(huan)也無法做(zuo)到(dao)無縫銜接的要(yao)求，所(suo)以，全(quan)部(bu)是(shi)由行車(che)電腦來完(wan)成的。

電(dian)動(dong)機加上(shang)發動(dong)機，在(zai)不同動(dong)力輸(shu)出(chu)之間(jian)的切(qie)換(huan)(huan)，是(shi)在(zai)車輛動(dong)力需(xu)求變化之時(shi)，就(jiu)直接切(qie)換(huan)(huan)的，以保障動(dong)力輸(shu)出(chu)的無縫銜(xian)接。如果是(shi)手動(dong)來操作，就(jiu)像我們駕駛(shi)手動(dong)擋車型(xing)時(shi)，手動(dong)切(qie)換(huan)(huan)檔(dang)位(wei)一樣，在(zai)某些特殊(shu)的情況下，操作控制的不好，就(jiu)很容易出(chu)現(xian)頓(dun)挫，檔(dang)位(wei)切(qie)換(huan)(huan)錯(cuo)誤(wu)，甚至造成車輛熄火(huo)的情況。

在油電混合(he)車(che)型(xing)實際的(de)駕駛(shi)中，如(ru)果還需要手(shou)動(dong)切換電動(dong)，或者發動(dong)機(ji)驅(qu)動(dong)的(de)模式，是(shi)不(bu)是(shi)就(jiu)有點像，我們駕駛(shi)著一(yi)輛電動(dong)車(che)，又帶(dai)著一(yi)臺(tai)發動(dong)機(ji)。電池(chi)沒電了，我們就(jiu)打開發動(dong)機(ji)，讓(rang)發動(dong)機(ji)來(lai)工作(zuo)，然后也給(gei)電池(chi)充電，就(jiu)需要不(bu)時地去手(shou)動(dong)操作(zuo)了，這車(che)開起來(lai)也太復雜了。

所以，綜合以上說明，油電混合車是不(bu)需(xu)要手動(dong)(dong)(dong)切換(huan)(huan)動(dong)(dong)(dong)力(li)的輸(shu)出(chu)模式的。動(dong)(dong)(dong)力(li)輸(shu)出(chu)的切換(huan)(huan)行車電腦(nao)會根(gen)據車輛(liang)實際的動(dong)(dong)(dong)力(li)需(xu)求，在不(bu)同的驅動(dong)(dong)(dong)模式之間無縫銜接的切換(huan)(huan)。保障車輛(liang)的動(dong)(dong)(dong)力(li)的輸(shu)出(chu)，同時，又提高(gao)車輛(liang)的燃油(you)經濟(ji)性，減少(shao)車輛(liang)的排放(fang)。
