Abstract:
1. A method for controlling an automated friction clutch disposed between an engine and a transmission of a motor vehicle, the method comprising: detecting a set of operating state variables of the drive train; computing a first component of a clutch torque, the first component being essentially engine torque-dependent, wherein the computing of the first component is performed using at least a first operating state variable from the set; computing a second component of the clutch torque, the second component being slip-dependent, wherein the computing of the second component is performed using at least a second operating state variable from the set; determining the clutch torque from the first and second components; controlling the clutch so as to transfer the clutch torque; computing and correcting at least one parameter of a controller based on at least a third operating state variable from the set; and adapting the first component using an i-component of the controller in the sense of a reduction of the i-component and wherein the determining of the second component is performed using the controller according to a variance between actual slip and a setpoint slip, the setpoint slip being determined using at least the second operating state variable from the set, wherein during a rapid change of the position of the load control element, the first component is determined using the position of the load control element and a rotational speed of the engine, and during a slow change of the position of the load control element, the first component is determined using additional engine operating variables.
