Vehicle Calibration for DriveabilityCustomer RequirementsFor brand differentiation purposes individual driveability calibration with respect to emission targets, fuel consumption, climatic conditions and market specific demands is required. In gasoline calibration different fuel qualities have to be considered as well.
A big number of vehicle derivatives with different gearbox concepts and chassis variants have to be considered. This requires an integrated view of the complete vehicle and all its sub-systems. Due to limited ressources and development time all synergy effects have to be utilized. An easy and consistent calibration data management through the complete development process is mandatory.

AVL ApproachAVL’s tradition in combustion development is the basis for understanding and optimization of transient engine behaviour which highly determines the vehicle driving behaviour.
To ensure that the driveability calibration meets exactly the brand-specific requirements, AVL works in a very close cooperation with the manufacturer’s driveability experts. Common Assessments are carried out locally at customer’s site on proving grounds and during the climatic test trips.
AVL’s approach to a most efficient calibration process is to use the tool AVL DRIVE which allows to make the subjective target become an objective one.
To handle the synergies between similar vehicle variants AVL has established a professional data management tool and clearly defined release procedures. |
