A New Calibration System for the Daimler Chrysler Medium and Heavy Duty Diesel Engines - An Exercise in Methods & Tools 2001-01-1222
High demands in fuel consumption, efficiency, and low emissions lead to complex control functions for current and future diesel engine management systems. Great effort is necessary for their optimal calibration.
At the same time, and particularly for cost reasons, many variants exist on one individual type of diesel engine management system. Not only is it used for several base engines, but these engines are also used in different environments and for different tasks. For optimal deployment, their calibration status must also be optimized individually.
Furthermore, the demand for shorter development cycles and enhanced quality lead to a catalogue of new requirements for the calibration process and the affiliated tool. A new calibration system was developed, which optimally reflects the new demands.
The paper here provides an overview of how these new demands have been met, starting with the initial requirements of enhanced data management, reproducibility and quality assurance, safety and better ergonomics. Also shown is how the new international ASAM/ASAP standards have been implemented creating crucial interfaces for an open system.
The results section summarizes the benefits, which have arisen for the everyday calibration process, as well as for new approaches in the development, calibration and validation processes, which have not been feasible before.
