Abstract
A process for continuously controlling the degree of locking of open differential drives in a driven axle of a multi-axle vehicle, in the case of which a nominal value .DELTA..sub.v soll of the differential speed at the wheels driven via the differential gear is determined as a function of the vehicle speed v.sub.F determined at the non-driven wheels and which records the wheel speed differential .DELTA..sub.v ist between the wheels driven via the differential gear, which wheel speed differential .DELTA..sub.v ist is readjusted by varying the locking effect on the nominal value .DELTA..sub.v soll of the differential speed always deviating from zero.
