MiL-Based Calibration and Validation of Diesel-ECU Models Using Emission and Fuel Consumption Prediction during Dynamic Warm-Up Tests (NEDC) 2012-01-0432

A calibration and validation workflow will be presented in this paper, which utilizes common static global models for fuel consumption, NOx and soot. Due to the applicability for warm-up tests, e. g. New European Driving Cycle (NEDC), the models need to predict the temperature influence and will be fitted with measuring data from a conditioned engine test bed. The applied model structure - consisting of a number of global data-based sub-models - is configured especially for the requirements of multi-injection strategies of common rail systems.
Additionally common global models for several constant coolant water temperature levels are generated and the workflow tool supports the combination and segmentation of global nominal map with temperature correction maps for seamless and direct ECU setting.
To globally validate the ECU calibration with respect to emission limits, fuel consumption and special regard to transient operation phases, the complete model chain will be stimulated with NEDC warm up tests. At the end of the workflow, the MiL-environment allows to improve the ECU labels (maps and curves) in a convenient time and resource saving manner.
