Abstract: Dual clutch transmissions (DCTs) refer to the double friction clutches; they are designed and operated fully automated in vehicle shift gearbox. The biggest advantage of the DCTs is the improvement of the fuel economy because the power flow from the engine to the transmission is always has a very high friction coefficient and is not interrupted. The current six-speed DCTs can provide more than 10% better fuel economy compared to the conventional six-speed automatic gearbox. This paper develops three vehicle models: conventional dual clutch transmission (DCT); conventional hybrid electric vehicle (HEV); hybrid dual clutch transition (HDCT). They are simulated on different drive-cycles. HEV and HDCT proved the superiority on fuel savings in low speeds. HDCT shows a little bit higher energy saving over HEV due to the higher efficiency of clutches to torque converters. Conclusions and recommendations for the development of DCT, HEV, and HDCT are also outlined.
