IAV EasyDoE

Simplified Model-based Calibration, 2016

IAV EasyDoE:Motivation

  • •More restricted emission legislation requirements worldwide
  • •More transient and more realistic drive cycles need optimization of whole ECU maps
  • •More complex engines and exhaust aftertreatment systems
  • •More ECU labels to calibrate 
  • Model Based Calibration with IAV EasyDoE

    Process Steps from Task Definition to Optimized ECU Calibration

    IAV EasyDoE:Advanced Calibration

    Challenge:

        •Unknown engine operation limits

        •Many parameter with complex interactions

    Solution: Advance Test Design Definition

        •Import results of ORION BoundaryFinder directly as design space for the test plan

        •Support for multiple injections (prevent injection collisions)

        •Optimize ECU maps with a flexible target and constraints definition

    IAV EasyDoE:Advanced Calibration

    Model Fitting:

        •Most advance model types are included (GPM, Hilomot, RBF)

        •Robust Polynomial models are included

        •High flexibility of models allow a one zone approach covering the whole engine operation area

        •One click model fitting with automatic best model selection

    IAV EasyDoE:Summary

    IAV EasyDoE for Model-based Engine Calibration:

        •Based on IAV expert knowledge

        •Workflow guided concept for calibration engineers

        •Fast and flexible test preparation

        •Integrated data quality check

        •Automated one click model creation

        •Powerful ECU map optimization

        •Extensible plug-in concept for Matlab-based tools
