A method for operating a clutch (10), whose clutch slip (s) is adjusted to a setpoint value (s0) 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 (s0), when the derivative of the friction coefficient/slip characteristic at this slip value exceeds a specifiable limiting value. In particular, the setpoint value (s0) is selected as a function of a number of operating parameters, inside a range of permissible setpoint values (s0); 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 (s0).
A control device (50) for a slip-controlled clutch (10), whose clutch slip (s) can be adjusted to a setpoint value (s0) using a manipulated variable, having a selector unit (68), which selects the setpoint value (s0) as a function of a number of operating parameters, and having a diagnostic unit (70), which only allows a setpoint value (s0) to be a permissible setpoint value (s0), when the derivative of the friction coefficient/slip characteristic exceeds a specifiable limiting value.
