A method of operating a vehicle drive-train including a drive engine, a transmission device and a drive output. At least one shifting element is provided in the transmission, whose transmission capacity for obtaining an operating condition of the transmission device can at least, in part, be continuously varied. During overdrive operation of the drive-train, torque present at the output can be supported at least partially by the transmission device in the area of the drive engine. During overdrive operation, the transmission capacity of one of the transmission shifting elements, which to obtain the current operating condition of the transmission device is essentially at least approximately zero, is set to a value at which at least part of the torque present at the drive output can be supported in the area of the transmission device, and the rotational speed of the drive engine has a value below a predefined limit value. |
