- System nach Anspruch 3, dadurch gekennzeichnet, dass die Grenzwerte beabstandet sind und/oder dass der erste Grenzwert den zweiten übersteigt.
- System nach Anspruch 3 oder 4, dadurch gekennzeichnet, dass wenigstens ein dritter vorgesehen ist, wobei der dritte Grenzwert den ersten Grenzwert übersteigt, und die Motorsteuerung (14) bei Überschreiten des ersten Grenzwertes eine bestimmte Menge an Leistungsverstärkung und ab dem dritten Grenzwert eine maximale Leistungsverstärkung ermöglicht.
- System nach einem oder mehreren der vorherigen Ansprüche, dadurch gekennzeichnet, dass die Menge an möglicher Leistungsverstärkung in Abhängigkeit von der Fahrgeschwindigkeit und/oder des Übersetzungsverhältnisses bzw. des eingelegten Gangs bestimmt wird.
- System nach einem oder mehreren der vorherigen Ansprüche, dadurch gekennzeichnet, dass die Motorsteuerung (14) die Menge an Leistungsverstärkung in Abhängigkeit von einer ermittelten Motor- bzw. Fahrgeschwindigkeitsänderung bzw. einer ermittelten Änderung eines Motor/Fahrgeschwindigkeitverhältnisses bestimmt.
- System nach einem oder mehreren der vorherigen Ansprüche, gekennzeichnet durch wenigstens einen Temperatursensor (16, 18, 20, 22, 24, 26) zur Ermittlung einer mit dem Motor verknüpften Temperatur.
- System nach Anspruch 8, dadurch gekennzeichnet, dass der Sensor (16, 18, 20, 22, 24, 26) eine Motoröltemperatur, eine Einlasskrümmertemperatur, eine Motorkühlmitteltemperatur, eine Getriebeöltemperatur bzw. eine Hydrauliköltemperatur ermittelt.
- System nach Anspruch 8 oder 9,dadurch gekennzeichnet, dass die Motorsteuerung (14) eine Leistungsverstärkung unterbindet, wenn die ermittelte Temperatur einen Temperaturgrenzwert übersteigt.
- System nach einem oder mehreren der vorherigen Ansprüche, dadurch gekennzeichnet, dass die Motorsteuerung (14) eine Leistungsverstärkung für eine variable Zeitdauer ermöglicht, welche vorzugsweise in Abhängigkeit von der Stärke der Leistungsverstärkung bestimmt wird.
- System nach Anspruch 11, dadurch gekennzeichnet, dass die Abhängigkeit zwischen der Stärke der Leistungsverstärkung und der Zeitdauer nicht linear ist.
