Automatic clutch controlling method for motor vehicle, involves reducing transferable coupling torque while laying channel depending on reference variable, where torque transferred by clutch is used as reference variable

The method involves reducing transferable coupling torque when laying a channel depending on a reference variable, where torque transferred by a clutch is used as the reference variable. A mathematical-physical model is utilized for the determination of the torque transferred by the clutch and a temporal derivative. The mathematical-physical model is held for determining slowly variable parameters and fast variable engine torque, such that the determination takes place during rapid changes of the engine torque and/or during adherent coupling. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for performing a method for controlling an automatic clutch (2) a device for controlling an automatic clutch. Steuerung einer automatisierten Kupplung, die in einem Antriebsstrang eines Kraftfahrzeugs zwischen einer Antriebseinheit und einem Getriebe mit einer Mehrzahl von Getriebestufen angeordnet ist, während des Auslegens eines Ganges im Getriebe, wobei das übertragbare Kupplungsmoment in Abhängigkeit einer Führungsgröße abgebaut wird.
