Method of correcting fill vol. of pressure-operated clutches in motor vehicle transmissions, esp. of lamella clutches, ensures uniform switching quality when clutch parts wear and/or settle

摘要

The method involves switching the clutch with a switching element with a fill pressure applied to the clutch during a filling period. A computer (6) determines a current switching element load state from predetermined process parameters of previous switching processes and obtains an empirically determined filling period for the determined switching state from a memory (7).
