Zusammenfassung
Of the three main automatic transmission types, the stepped automatic (AT), the continuously variable transmission (CVT) and the dual clutch transmission (DCT), the high mechanical efficiency of DCT technology [1] makes it a preferred technology for many hybrid vehicles. The mechanical efficiency of the DCT means it saves on both battery and engine demand to drive the vehicle. It is selected for hybrids because it provides high energy transfer efficiency, which delivers vehicle fuel economy performance improvements. The DCT is efficient in terms of mechanical efficiency as there are no torque converter losses [2].
