METHOD FOR REGULATING AN INTERNAL COMBUSTION ENGINE, COMPUTER PROGRAM AND CONTROL UNIT
First Claim
1. A method for regulating an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition and a combustion process of which is influenced by a manipulated variable, comprising:
- determining a desired value of a combustion position feature of the combustion process;
determining the manipulated variable by predictive closed-loop control based on a modeling of the combustion position feature as a function of the manipulated variable in the combustion process; and
determining, as the manipulated variable, a value at which the difference between the desired value of the combustion position feature and a model-based predicted combustion position feature is minimized.

Abstract
A method for regulating an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition and a combustion process of which is influenced by a manipulated variable, the method includes the steps of determining a desired value of a combustion position feature of the combustion process; determining the manipulated variable by predictive closed-loop control based on a modeling of the combustion position feature as a function of the manipulated variable in the combustion process; and determining, as the manipulated variable, a value at which the difference between the desired value of the combustion position feature and a model-based predicted combustion position feature is minimized.

15. A computer-readable storage medium containing program code configured to, when executed on a program-controlled device, perform the steps of a method for regulating an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition and a combustion process of which is influenced by a manipulated variable, the method comprising:
-
determining a desired value of a combustion position feature of the combustion process; determining the manipulated variable by predictive closed-loop control based on a modeling of the combustion position feature as a function of the manipulated variable in the combustion process; and determining, as the manipulated variable, a value at which the difference between the desired value of the combustion position feature and a model-based predicted combustion position feature is minimized.

16. A control unit for an internal combustion engine, the control unit comprising at least one arrangement configured to perform the steps of a method for regulating an internal combustion engine that is operable, at least in a part-load range, in an operating mode with auto-ignition and a combustion process of which is influenced by a manipulated variable, the method including:
-
determining a desired value of a combustion position feature of the combustion process; determining the manipulated variable by predictive closed-loop control based on a modeling of the combustion position feature as a function of the manipulated variable in the combustion process; and determining, as the manipulated variable, a value at which the difference between the desired value of the combustion position feature and a model-based predicted combustion position feature is minimized.
