Abstract
A method controls an automated dual clutch transmission of a motor vehicle. An actuating device, preferably arranged in the region of a steering wheel, for selecting the gear step of the shift transmission, which actuating device has a first and a second actuating element which, when actuated individually, cause an upshift or downshift of the shift transmission and, when actuated simultaneously, transfer the shift transmission into an idling state. When both actuating elements are actuated simultaneously, the force-transmitting clutch remains closed and consequently the selected gear remains engaged, and at the same time a clutch torque and/or an engine torque and, consequently, a drive torque acting on a driven wheel is reduced to approximately 0 Nm. It is thereby possible to tie up the force transmission again especially quickly after the termination of the idling state.
