A method of controlling at least one coupling in a powertrain of a motor vehicle includes the steps of: determining at least one slip value which represents an instantaneous slip between different axles of the motor vehicle or between different wheels of an axle; forming an absolute value of the slip value which corresponds to the amount of the slip value; summing the absolute value or a substitute value derived therefrom to a last-formed slip sum value to form an instantaneous slip sum value; comparing the instantaneous slip sum value with a slip sum threshold value: and generating a control signal for actuating the coupling if the instantaneous slip sum value reaches or exceeds the slip sum threshold value.
