Verfahren (10) zur Kupplungssteuerung eines Getriebes für ein Kraftfahrzeug während Herunterschaltbedingungen, wobei das Verfahren umfasst, dass:eine Bremswegnahmebedingung während Herunterschaltbedingungen ermittelt wird (22);ein minimaler geplanter Kupplungsdruck begrenzt wird, wenn eine Bremswegnahmebedingung ermittelt wird (22); unddie Beziehung des Kupplungsdrucks zu einem Drehmoment modifiziert wird (24). A clutch control process for a motor vehicle transmission during brake lift-out monitors a time rate of change of a brake pedal position and torque to detect a lift-out condition with rapidly changing torque. When the process detects a brake lift-out condition, the process limits the minimum scheduled clutch pressure as well as modifies the clutch pressure to torque relationship.
