  • Method for controlling a friction clutch
    Patent number: 8591382
    Abstract: A method for controlling a friction clutch operatively arranged between a drive unit and a gearbox. The method includes the steps of detecting torque transmitted by the friction clutch, determining a coefficient of friction between friction linings of a clutch disk and antifriction surfaces of the friction clutch, and evaluating the functional capability based on the determined coefficient of friction. In order to avoid an evaluation of a friction clutch that has not yet been broken-in as a worn friction clutch, the evaluation is postponed during a specified breaking-in phase of the friction clutch.
    Type: Grant
