  • Double clutch transmission for a hybrid electric vehicle and method for operating the same
    Publication number: 20070028718
    Abstract: A double clutch transmission is described that ideally changes torque received from an engine and a motor by providing an optimal layout in power transmission scheme and motor location. Such a double clutch transmission is optimally adapted to a hybrid electric vehicle, and an optimal operation method for such a double clutch transmission is also provided, overcoming inefficiency in application of a conventional CVT to an HEV.
