A method for operating a drive train having a variable speed transmission connecting a drive unit with an output drive. The transmission has gears that can be selected by the driver and has a clutch that can be manually actuated. The torque intended by the driver is determined based on accelerator pedal actuation and the drive unit is operated on that basis. Whenever the driver disengages the clutch and changes gears, the torque intended by the driver is not used for operating the drive unit, rather the drive unit is automatically operated by a rotational speed control. In a first phase rotational speed control, a target value is automatically determined, that is independent of the current transmission input speed, and used for the rotational speed control. During a second phase, a target value which is dependent on the current transmission input speed is used for the rotational speed control.
