Disclosed is a motor vehicle with a drive train comprising at least one controllable clutch, in which unwanted rpm oscillations on the output side of the clutch (2), e.g. due to the age of the clutch (2), are reduced by determining a variable for rpm oscillations on the output side and reducing the rpm oscillations according to the determined variable by means of a regulating mechanism which acts upon the controllable clutch (2). The regulating mechanism used for reducing rpm oscillations is advantageously limited regarding a minimum frequency in order not to influence an additional parallel regulating mechanism that also acts upon the controllable clutch (2). The oscillations can be suppressed without influencing existing regulating mechanisms by separately superimposing the control loop used for eliminating rpm oscillations upon other regulating mechanisms by means of a bandwidth limitation for the regulating mechanism used for reducing the rpm oscillations and an associated regulating mechanism, e.g. for controlling the rotational speed of the engine. |
