Vehicle Calibration for EaFC.jpg

Driveability Calibration Diesel Passenger Cars

Engine Driveability Calibration under all conditions by calibration of torque forming SW-functionalities combined with objective judgment of vehicle driveability to achieve higher calibration quality.

Vehicle Calibration is essentially determining the customer relevant attributes of a car at the same time fulfilling legislative standards, world-wide for all markets.

Main criteria for a successful product like

  • Fuel Consumption
  • Performance
  • Emission
  • Driveability
  • OBD compliance

have to be achieved in a documentation and tool environment that ensures efficient workflow, traceability and robustness to worldwide market demands.
