Abstract:
1. A dual clutch transmission comprising: two sub-drivetrains, each of said two sub-drivetrains having at least one shiftable gear and a friction clutch operating between each of said two sub-drivetrain and a combustion engine, a clutch disengaging system that actuates the two friction clutches, wherein an electric motor acts on each said friction clutch through a clutch disengaging mechanism; and, at least one control device to control the two friction clutches and shift said at least one shiftable gear of each of the two sub-drivetrains, wherein a routine is provided in the at least one control device to check the functional capability of the electric motors, wherein if there is a deviation (ΔPATH1, ΔPATH2) of the functional capability of said at least one electric motor from predefined values, all of the at least one shiftable gears of the sub-drivetrain whose assigned friction clutch is operated by the at least one electric motor are disengaged while the assigned friction clutch remains engaged.
