Abstract
In a slip-controlled system for road vehicles with all-wheel drive, the rear-axle differential gear (5) and/or the intermediate differential (3) are equipped with differential locks (33, 34). An electronic brake slip control unit (50) automatically disengages the differential locks (33, 34) partially or entirely upon the occurrence of an imminent locked condition or upon commencement of brake slip control. Coupling devices are provided as differential locks (33, 34) which allow coupling of the output shafts (8, 11; 9, 10) and which are isolated electrically or hydraulically in the control phase.
