Driveline Simulation

Measurement while vehicle testing

Data collection in vehicle tests using the measurement system winADAM developed by Steinbeis. Using our own measurement cars MB SL 350 und VW EOS 1,2 TSI we do vehicle testing according to customer´s demand and we measure data to describe the road (Topography, curvature), traffic parameters (traffic environment, density, driving type (no car in front, car in front, Kolonne)), driving parameters (speed, position, distance, accelleration, etc) and parameter of the driveline (rotating speeds, moments, gear, fuel injection amount, etc.). If wanted we rent each wished car and prepare and use it for vehicle measurements defined by the customer. This also is done for heavy vehicles and construcvtion machines.

Driving behaviour, fuel consumption, pollutions

Examples of our projects:

  • prediction of fuel consumption on a test track for different driveline concepts (3 l-car) and research of drivers characteristic
  • Possible fuel reduction by management of auxillary consumers
  • Possible fuel reduction by motor stop
  • Possible fuel reduction by storage of breaking energy,
  • Possible fuel reduction by energy optimised tires
  • Simulation of driveline management to optimize the braking energy storage system
  • Comparison of differnt gear systems for fuel consumption
  • Influence of gear losses to the fuel consumption
  • comparison of the primary energy for a new system of of eletrical driven trucks and the existing railway system for the Alps Transit NEAT (New European Alps Transversale)
  • Fatigue life prediction of a retarder shaft for given driving cycles of a truck
  • Influence of manual gear shifting to the gear life.
  • Investigation of new shifting technologies in automatic transmissions by SIL (Software in the Loop-Simulation)
  • Fatigue Life of gearbox components under realistic driveng cycles
  • Investigation of continious transmissions based on power split hydrostatic systems
  • Driving simulation of CVT to develop a efficient regulation strategy
  • Simulation of different driveline concepts to select an optimum gear
  • Thermal behaviour of electric motors under realistic driving cycles in commercial vehicles
  • Influence of the traffic density to the speed of commercial vehicles and the resulting fuel consumption
