Combustion process model-supported predictive regulation method for internal combustion engine, involves adjusting model parameter during presence of pre-determined condition to optimize model

摘要

#CMT# #/CMT# The method involves operating an internal combustion engine with self ignition in a partial load region in an operating mode. Model-supported predictive regulation of a combustion process is performed based on a model of the combustion process under consideration of a planned adjustment intervention and a model parameter of the combustion process. The model parameter is adjusted during the presence of a pre-determined condition to optimize the model. Measured characteristic of the combustion process is subjected to a low-pass filtering before the difference formation. #CMT# : #/CMT# Independent claims are also included for the following: (1) computer program comprising a set of instructions for performing a method for regulating a combustion process in an internal combustion engine (2) a computer program comprising a set of instructions for performing a method for regulating a combustion process in an internal combustion engine (3) a controller for an internal combustion engine. #CMT#USE : #/CMT# Method for model-supported predictive regulation of a combustion process in an internal combustion engine of a vehicle. #CMT#ADVANTAGE : #/CMT# The model parameter is subjected to a regulation on the basis of the difference between an actual value and a desired value of a reference variable, so that a fast adjustment of the model parameter is made possible. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graph illustrating the modeling of a predictive combustion balance point on the basis of physical process parameters.
