ABSTRACT:
A method for increasing the drive torque achieves the action of a differential lock in that controlled brake engagement takes place on one side of a driven axle provided that there is a speed difference between the wheels on the different sides of a driven vehicle axle which exceeds a threshold value. The regulation engagement is started even when there are only small speed differences between the wheels on the two sides of the driven axle. A reference velocity of the vehicle is determined and, on the basis of the determined reference velocity, wheel calibration and cornering correction take place, and thereafter, the speed difference is determined therefrom. The speed difference thus determined is substantially based on the difference in the adhesion on both sides of this axle.
