In a method for operating a drive train for a motor vehicle, a torque is produced by means of an internal combustion engine as a function of an available torque set value signal and transmitted to drive wheels by means of a clutch. With the help of an electric motor, a closing force is applied, with which the clutch is held in a closed position against a restoring force. The electric motor is energized in such a way that a high current is used in the case of a high torque and a lower current is used in the case of a lower torque. The thermal load of the electric motor is determined and a load signal corresponding to the thermal load is produced. The load signal is compared with a load limit signal assigned to a permissible load range. If the load signal deviates from the load-limit signal, the torque of the internal combustion engine is limited.
