Abstract
During a special scientific project (SFB 365), supported by the
DFG, a parallel hybrid concept for passenger cars, called the
Autark Hybrid, was developed, assembled and investigated.
The drive line consists an electric engine supplied by a
120V-Ni/MH-battery for about 30 km electrical driving distance and
a turbo diesel engine. Both engines use the same gearbox, the
i2-gearbox, which is specially designed to have a wide spreading.
Significant fuel savings are achieved by recuperation of kinetic
energy and by avoidance of inefficient operation of the ic-engine
at areas of low power demand.
The results from the research project concerning fuel
consumption, respectively fuel saving will be presented and
discussed in this paper. The adjustment between simulation and test
rig investigations shows problems by the practical realisation of
operation strategy and operation mode of the powertrain elements.
As result smaller fuel savings can be realised than predicted.
