創(chuàng)造簡潔的的方案來解決復(fù)雜問題的是本田專業(yè)。混合系統(tǒng)初到美國的時候，本田擊敗豐田的市場，僅僅通過在發(fā)動機(jī)的飛輪簡單安裝一個交流電機(jī)。這樣的設(shè)計(jì)，被稱為整合混合動力系統(tǒng)，它緊湊和高效的但到2006都沒有提供純電動驅(qū)動?，F(xiàn)在，混合系統(tǒng)在原有的普銳斯以及連續(xù)的混合系統(tǒng)演變成充電混合系統(tǒng)，本田已經(jīng)創(chuàng)建了一個新的，兩個馬達(dá)動力系統(tǒng)布局而且基于復(fù)雜CVT傳動系統(tǒng),。2014HondaAccordhybridThesecondaryACmachineissmallerandservesmainlyasagenerator,providingthedrivemotorwithelectriccurrenttoaugmentorreplacejuicefromthebatteryduringcruising.Oncue,thismachinestartstheenginesoitcansupplytherequiredtorque,butitneverdrivesthewheels.

二次交流機(jī)小，主要用作發(fā)電機(jī)，提供驅(qū)動電動機(jī)的電流增加或替換的電池在巡航。恰在這個時候，這臺機(jī)器啟動發(fā)動機(jī)，這樣它可以提供所需的轉(zhuǎn)矩，但它從來沒有驅(qū)動車輪。Asinmosthybrids,itusesanAtkinsoncycle(late-closingintakevalves)thatsacrificessomelow-rpmtorquetogainmid-rangeefficiency.Atwo-modevariableintake-valve-timingandliftsystemprovidesextrapowerforaccelerationandmaximumefficiencyduringcruising.

在大多數(shù)的混合系統(tǒng)中，它采用阿特金森循環(huán)（延遲關(guān)閉進(jìn)氣閥），犧牲一些低轉(zhuǎn)速扭矩增加中檔效率。在巡航雙模式可變進(jìn)氣門正時和升系統(tǒng)提供額外的動力加速度和最大效率。NotcountingthelateFiskerKarma,theHondaAccordistheonlyhybridwithoutatransmission
