Abstract:
The invention relates to a method for controlling a drivetrain having an internal combustion engine, a dual-clutch transmission, having a first and second sub-transmission having at least one shiftable gear ratio, a first friction clutch disposed between the internal combustion engine and the first sub-transmission and a second friction clutch disposed between the internal combustion engine and the second sub-transmission to provide a drivetrain torque at a transmission output of the dual-clutch transmission by transferring an engine torque adjusted thereto via the friction clutches. So as to be able to continue operating a friction clutch which may have a previously damaged friction lining, at a first clutch torque transferred via the first friction lining, depending on a friction coefficient and a current temperature of a second friction lining of the second friction clutch, the second friction clutch is engaged at a gear ratio selected in the second sub-transmission and the friction lining is heated to a specified temperature.
