Abstract
A method for operating a clutch ( ), whose clutch slip (s) is adjusted to a setpoint value (s ) with the aid of a manipulated variable, should allow a clutch to be controlled in a particularly reliable and stable manner. To this end, the present invention provides for a slip value only being permitted to be a setpoint value (s ), when the derivative of the friction coefficient/slip characteristic at this slip value exceeds a specifiable limiting value. In particular, the setpoint value (s ) is selected as a function of a number of operating parameters, inside a range of permissible setpoint values (s ); the slip value, at which the derivative of the friction coefficient/slip characteristic falls below a specifiable limiting value, being selected as an upper limit (G) of the range of permissible setpoint values (s ).
