Abstract

In order to avoid faults as a result of different diameters of tires, under prescribed conditions a correction of one wheel speed with respect to the other on each side of the vehicle is performed. The conditions are based on a comparison of the throttle valve angle to the zero torque angle, and a comparison of the speed of the driven wheel to the speed of the non-driven wheel.
