Optimizing model for controlling internal combustion engine involves taking smoothing of characteristic relationship into account for model optimization in addition to actual output parameters

摘要

The model (20) uses at least one characteristic relationship (25) when computing an output parameter (27) from input parameters (21-24). The method involves measuring input and output parameters on an internal combustion engine and varying the characteristic relationship taking into account deviations between computed and measured output parameters to optimize the model. Smoothing of the characteristic relationship is also taken into account.
