Abstract
Due to the decreed reduction of the exhaust
emissions of motor vehicles the vehicle industry is
forced to make the internal combustion engines and
the auxiliaries more e ective and cleaner. An essential
reduction of the fuel consumption and the exhaust
emissions can be realised by drive train optimisations
of the auxiliaries.
For the investigation of the energy consumption of
conventional and innovative auxiliaries an entire vehi-
cle simulation was developed and implemented. Mat-
Lab/Simulink was used as the simulation tool. In the
simulation model the energy
ows in entire motor
vehicle were determined and innovative concepts of the
auxiliaries were investigated. A variable drive train of
each auxiliary and an uncoupling of each auxiliary from
the internal combustion engine were implemented.
With this setup the lowest fuel consumption of the mo-
tor vehicle can be achieved. Especially the e ects of the
driver and the driving cycle on the fuel consumption
of the entire motor vehicle were observed.
An entire vehicle simulation is developed to calcu-
late the e ciency of the conventional motor vehicle
with conventionally and innovative operated auxil-
iaries. Three di erent types of real driving cycles were
measured to validate the vehicle simulation model. A
comparison of the simulation and measurement results
will be presented. The fuel consumption reduction of
the entire vehicle was calculated and simulated using
the conventionally operated and the innovative oper-
ated auxiliaries. The saving potential of the exhaust
emissions and the fuel consumption will be presented
and discussed.
