ABSTRACT:
In a system for the automatic control of form-locked clutches serving as differential lock in drive axles of a motor vehicle, in which control signals for a coupling actuator are formed by comparison of slippage signals with threshold values, both the engagement and the disengagement of the lock clutch are to be better adapted to the operating conditions which occur in practice. For this purpose, slippage sum signals (SSLR, SSFH) formed by integration of the speed differences (DFLR, DFVH) are compared with slippage sum thresholds (SSSLR1, SSSLR2, SSSVH1, SSSVH2) and the actuating time of the actuator is controlled as a function of further traveling conditions.
