Engine torque i.e. toque of drive machine such as internal combustion engine, reducing method for motor vehicle, involves reducing engine torque with closed clutch based on difference between engine and gear input speeds

The method involves reducing an engine torque with a closed clutch depending on a difference between an engine speed (nm) and an gear input speed (nk) when a predetermined value of the speed difference exceeds. The engine speed is provided within a defined range and a defined full-load operation is...

Beschreibung
Zusammenfassung:	The method involves reducing an engine torque with a closed clutch depending on a difference between an engine speed (nm) and an gear input speed (nk) when a predetermined value of the speed difference exceeds. The engine speed is provided within a defined range and a defined full-load operation is determined. The amount of reduction of the engine torque is provided to be proportional to the amount of the speed difference. Bei einem Verfahren zur Reduzierung des Motormoments in Kraftfahrzeugen wird abhängig von der Drehzahldifferenz zwischen der Motordrehzahl und der Getriebeeingangsdrehzahl bei geschlossener Kupplung das Motormoment reduziert, wenn ein vorgegebener Wert der Drehzahldifferenz überschritten wird. Vorzugsweise wird bei geschlossener Kupplung das Motormoment nur dann reduziert, wenn sich die Motordrehzahl innerhalb eines definierten Bereiches befindet und/oder wenn ein definierter Volllastbetrieb erkannt wird.
