Abstract

A vehicle is described, with a drive engine arranged in the transverse direction of the vehicle, with vehicle cross-shafts of a vehicle axle that can be driven by the drive engine and with a transmission unit for the variable distribution of the drive torque from the drive engine in the vehicle's transverse direction between wheels connected to the vehicle cross-shafts. The transmission unit has an input shaft and two output shafts, with two planetary gearsets and an electric machine arranged between two interconnected shafts of the planetary gearsets for the variable distribution of the torque delivered by the input shaft between the two output shafts as a function of torque produced by the electric machine. The electric machine is brought into active connection with the transmission unit and with the drive engine via shiftable clutch devices such that the degree of distribution between the output shafts of the transmission unit can be varied when the electric machine is operating as a motor and as a generator. The electric machine can be driven directly by the drive engine to operate as a generator.
