Mobility and fuel economy of hybrid-driven vehicles in terrain~Results from computer simulation 2000-05-0394
An important requirement for the application of hybrid drives in
future terrain vehicles is their competitiveness with regard to the
driving properties and the fuel economy. Therefore, a two-axle,
all-wheel-driven military transport vehicle equipped with a serial
hybrid propulsion system has been regarded and examined by computer
The tool, used for this purpose, is the simulation program
ORSIS, (Off Road Systems Interactive Simulation), which has been
developed at the University of the Federal Armed Forces in Hamburg.
By generating a realistic surrounding area with reproducible
conditions ORSIS allows an objective comparison of different
vehicle types and the investigation of the influence of modified
The paper presents results from computer simulations which
include acceleration and braking procedures, determination of
maximum drawbar pull, and the estimation of fuel consumption under
realistic conditions by driving on determined routes.
