A vehicle drive-train with a drive engine, a drive output and a transmission device connected in the power flow between the drive engine and the drive output. The transmission device has at least two transmission units whose transmission ratios can be varied continuously, at least in some ranges, and which are arranged in power-trains running parallel with one another between the drive engine and the drive output. The power-trains can each be functionally connected with a respective axle of the drive output. At least one shifting element is provided by which the power-trains can be functionally connected in the area between the transmission units and the drivable axles. In addition, a method for operating the vehicle drive-train is described, in which the shifting element is actuated as a function of torque to be transmitted via the transmission device between the drive engine and the drive output.
