Abstract

A method of controlling a friction-based torque-transmitting system in the drive train of a motor vehicle has the following steps: PA0 a) monitoring the respective rates of rotation of an input element and an output element of the torque-transmitting system, PA0 b) establishing and analyzing a correlation between said rates of rotation; and PA0 c) initiating a change in the operating mode of the torque-transmitting system if the correlation is found to have changed in excess of a given threshold limit.
