METHOD FOR CONTROLLING A DRIVE TRAIN HAVING A DOUBLE-CLUTCH TRANSMISSION

摘要

The invention relates to a method for controlling a drive train having an internal combustion engine, a double-clutch transmission, having a first and a second sub-transmission having at least one switchable transmission ratio, a first friction clutch arranged between the internal combustion engine and the first sub-transmission and a second friction clutch arranged between the internal combustion engine and the second sub-transmission for providing a drive train torque on a transmission output of the double-clutch transmission by transferring an engine torque adjusted thereto via the friction clutches. In order to be able to continue operating a friction clutch which may have a previously damaged friction lining, at a clutch torque transferred via the first friction clutch, depending on a friction coefficient and a current temperature of a second friction lining of the second friction clutch, the second friction clutch is applied in a slipping manner at a transmission ratio engaged in the second sub-transmission and the friction lining is heated to a specified temperature.
