Abstract:
1. A method for controlling a twin clutch transmission with two partial drive trains, which respectively feature multiple executable gearshifts, and in which one partial drive train is operated respectively with one gear actively engaged and in which, in another partial drive train according to a preselection strategy, a gear is engaged for a subsequent driving operation, in which a friction clutch is assigned respectively to one partial drive train, which is actuated by an actuator activated travel- or force-dependently by a control device and, upon attaining or exceeding a default threshold, transmits maximum clutch torque, the method comprising: if the maximum clutch torque of a friction clutch falls short of a predefined threshold value and once a clutch temperature assigned to this friction clutch is exceeded, an emergency operation is initiated, in which the partial drive train corresponding to the affected clutch is deactivated by opening the friction clutch, changing the preselection strategy, and activating the other partial drive train, wherein, depending upon falling short of a clutch temperature, the emergency operation is deactivated and normal operation restored, wherein a damage index is calculated besides a clutch temperature.
