Abstract

The invention relates to a method for the electronic control of the brake force distribution according to a differential slip or differential velocity between at least one wheel of the front axle (2) and at least one wheel of the rear axle (8) of a vehicle wherein if a differential slip threshold value or a differential velocity threshold value is exceeded by the differential slip or the differential velocity the brake pressure at the rear axle is limited. According to the invention the differential slip threshold value or the differential velocity threshold value is determined according to the braking demand.
