Leichte Nutzfahrzeuge stellen ein großes Segment im Bereich Nutzfahrzeuge dar. Diese Fahrzeuge werden für unterschiedlichste Aufgaben eingesetzt. Die Berücksichtigung von Umweltthemen aber auch wirtschaftliche Betrachtungen zeigen, dass Hybridantriebe in diesem Fahrzeugsegment eine interessante Antriebslösung darstellen. Es werden verschiedene Hybridsystemansätze miteinander verglichen und Vor- bzw. Nachteile aufgezeigt. Auf Basis von Simulationsmodellen werden Einzelkomponenten des Systems definiert bzw. die Wirkungsweise verschiedener Funktionen bewertet. Abschließend wird für diese Fahrzeuggruppe eine Standardlösung ermittelt und vorgestellt.
Light commercial vehicles are a rapidly crowing vehicle segment. These vehicles are used for several purposes e.g. supply of different goods, construction areas, special applications A high number of vehicles are used in cities or in urban arena with a high density of traffic and typical environmental polluting. In the meantime legislation in several industrialized countries around the world have the target to protect environment, e.g., Euro 4 or 5 regulations or Japan 10. In parallel the automotive industries (ACEA) in Europe has given a self obligation to reduce the CO 2 emission until 2008 to a value of 140 g/km. A lot of activities are started by automotive industry and there suppliers in the past to meet these requirements. Beside already well known development activities like weight optimisation, lower driving and air resistance or improved diesel engine the hybrid power train, a combination of electric motor generator and combustion engine seems to be in the future an imported solution to meet these requirements in the future. Several possibilities to realize a hybrid power train for these applications is shown including the possibilities ZF have to show a hybrid power train for these types of applications. The advantages and disadvantages of the several possibilities are discussed from different point of view. The needed basic functions of a hybrid power train are discussed and system is recommended to use for these types of applications. A simulation model is shown and described including the realisation and results for different driving cycles. The influence on fuel consumption and emissions divided by functions are shown. A solution optimised for light commercial application is shown. Further more first results based on practical experiences are described.
