A target engine rotational speed depending at least upon the position of an accelerator pedal position and a motor vehicle speed is determined in a method for controlling the operation of a motor vehicle drive train having a drive motor and a branched power transmission with several steplessly adjustable transmission ratio regions, between which shifting takes place at a predetermined range shift transmission ratio. A transmission ratio corresponding to the target engine rotational speed and vehicle speed is determined and set, whereby the change with respect to time of the accelerator pedal position and/or the change with respect to time of the target engine rotational speed is used for determining the target engine rotational speed and is filtered when a difference between the actual transmission ratio and a transmission ratio shift range falls below a limit value.
