Abstract

The proposal is to compare determined measurement values in the form of the actual engagement position to a set engagement speed of the clutch apparatus with a set position and a set engagement speed so that, upon the attainment of a known set-position and the presence of a defined deviation or a trend toward a diversion in the concept of an over-stepping of the set engagement speed, the set engagement speed of the clutch apparatus is braked to a predetermined engagement speed which prevents an undesired engagement impact of the clutch apparatus or at least alleviates an excessive engagement speed.
