ABSTRACT:
A method for recalibration of parametric relationships used in exhaust gas recirculation EGR control. When such recirculation would typically be inactive, relationships between parameters are measured, such relationships being normally measurable only with inactive EGR. New information from those measurements is combined with information from previous calibrations to provide update information necessary for subsequent EGR control.
