The invention relates to a method for controlling a power train with an internal combustion engine outputting an engine torque controllable by means of an accelerator pedal, with a dual clutch received on the crankshaft of said internal combustion engine having two friction clutches controlled by a clutch actuator regulated by specifying a target value of a clutch position corresponding to a clutch torque and a dual-clutch gearbox having two partial transmissions with gears arranged relative to one another, each having a gearbox input shaft that can be coupled to a friction clutch, wherein the dual-clutch gearbox is shifted in that, with a closed first friction clutch of a first partial transmission and a gear engaged therein having a first transmission ratio and an opened second friction clutch of a second partial transmission and a gear engaged therein having a second transmission ratio, the first friction clutch is opened and the second friction clutch is closed with engine torque held constant and a slip speed during the closure of the second friction clutch is adjusted by means of a controller of the first friction clutch. In order to execute overlapping shifts between speeds of the two partial transmissions adaptively and more comfortably, operating conditions for a selection of predetermined shifting situations between two predetermined gears are checked during an ongoing shift for deviations from a predetermined value and, if the value is exceeded, a countermeasure provided for rectifying the deviation is stored and the countermeasure is used to maintain the target value in at least one subsequent application of the corresponding shifting situation.
