Abstract

A method for operating a drive train of a vehicle with a drive engine, a brake system, at least two vehicle cross-shafts of a first vehicle axle with at least two wheels. The cross-shafts being actively connected via a transverse distributor gear and being driven by the engine. The vehicle also possibly having a second vehicle axle with at least two wheels. Frictional shift elements of the first vehicle axle, between the wheels of the first vehicle axle and the transverse distributor gear, are provided for variable distribution, to the first vehicle axle, of the fraction of the drive torque from the engine in the transverse direction of the vehicle between the two wheels. A desired yaw torque is determined. The drive engine, brake system and shift elements are controlled such that the desired yaw torque is produced essentially without changing the positive forward drive of the vehicle.
