1. A method for operating a drive system for a motor vehicle having an internal combustion engine and having an electric motor in drive connection with the internal combustion engine, wherein the internal combustion engine is operatable in a partial operating state as well as in a full operating state, the method comprising:

  • defining a first threshold for a target drive torque to be applied by the drive system for a switchover from the partial operating state into the full operating state;

    delaying a switchover, after the first threshold is exceeded, for a defined period of time;

    compensating a difference between a target drive torque and an actual drive torque of the internal combustion engine for the electric motor; and

    switching-over, after the period of time has elapsed, from the partial operating state to the full operating state if the first threshold value continues to be exceeded or ending a compensating operation of the electric motor if the torque has fallen below the first threshold again after the period of time has elapsed or as soon as this occurs during the period of time.
