The invention relates to a method for controlling a drivetrain having an internal combustion engine controlled dependent on a load demand on a target engine torque and having a dual-clutch transmission with two sub-transmissions, each having a friction clutch positioned operatively between the internal combustion engine and a sub-transmission with a changing maximum transferable clutch torque, wherein a specified clutch torque is set along an actuation travel path by means of a clutch actuator, a clutch characteristic of the transferable clutch torque is continuously adapted over the actuation travel path, and a maximum engine torque for a sub-transmission, which is reduced in comparison to the target engine torque, is limited to the maximum clutch torque transferable by means of the friction clutch of that sub-transmission.
