Demands on reliability are high. Investigations were made using modelling, simulation, model reduction and identification, with the focus on model reduction. The resulting concepts for consumption reduction vary depending on the vehicle type and application. [German] Das Nebenaggregate-Management hat den bedarfs-, verbrauchs- und abgasorientierten Betrieb der Nebenaggregate im Kraftfahrzeug zum Ziel. Der sehr weit gespannte Einsatzbereich von Kraftfahrzeugen und die hohen Anforderungen an die Betriebszuverlaessigkeit stellen entsprechende Anforderungen an das Management. Zur Untersuchung eines verbesserten Betriebs von Nebenaggregaten wrden Verfahren der Regelungstechnik wie z.B. Modellbildung, Simulation, Modellreduktion und Identifikation eingesetzt, wobei der Modellreduktion in anbetracht des komplexen Gesamtsystems Kraftfahrzeug eine besondere Bedeutung zukommt. Ergebnisse der Untersuchungen sind Konzepte zur Verringerung des Verbrauchsanteils der Nebenaggregate, die je nach Fahrzeugtyp und Einsatzzweck variieren.
