Patent ID: 7860632

Claim:
A method for operating and controlling a motor vehicle drive train and at least one of its components, said drive train being coupled at a drive end to an internal combustion engine, a clutch device and a transmission device being disposed within said drive train and wheels being disposed at a driven end of the drive train in such a manner that said wheels are operatively arranged to be driven by the internal combustion engine via the drive train, comprising the steps of: detecting at least one input signal in a time slot, which comprises a temporal progression of at least one rotational parameter of a drive train section and a corresponding output; electronically conditioning and evaluating said at least one input signal a plurality of times in a parallel manner and according to different characteristics; and, using at least one comparison of the conditioning and evaluation results of at least one input signal to determine whether transmission behavior of the drive train or at least one pre-determined drive train component changes.
