Abstract
A system and method for controlling a powertrain, comprising an internal combustion engine connected to a double clutch transmission having a first and a second partial transmission with at least one shiftable transmission stage. A first friction clutch is arranged between the internal combustion engine and the first partial transmission, and a second friction clutch is arranged between the internal combustion engine and the second partial transmission. An engine torque of the internal combustion engine is transmitted by the first and second friction clutches to the first or second partial transmissions to provide a drivetrain torque at the output of the double clutch transmission. The powertrain is monitored for an occurrence of juddering oscillations, wherein in response to juddering oscillations being detected a regeneration process of one of the first and second friction clutches is triggered, and a friction lining is removed in the regeneration process.
