wobei die Referenzdrehzahl unterhalb eines vorherbestimmten Grenzwerts der Bewegungsenergie des Fahrzeugs eine Funktion des Grads der Drossel klappenöffnung ist; und
die Referenzdrehzahl abgesenkt wird, wenn sie über dem Grenzwert der Bewegungsenergie des Fahrzeugs liegt, um einen raschen Eingriff der Kupplung in eine voll eingerückte Position zu fördern.
unter dem vorherbestimmten Wert der Druckplatten drehzahl.
Rref = Rint + K1 + K2á ist; und
über dem vorherbestimmten Wert der Druckplattendrehzahl:
Rref = Rint + K1 + K2á - K3dRdp/dt ist;
wobei:
Rref = Referenzdrehzahl;
Rint = Motordrehzahl zu Beginn der Einrückung;
α = % der Drosselklappenöffnung; und
Rdp = Drehzahl der Druckplatte.
