Abstract:
1. A computer-readable storage medium storing a computer program including a plurality of program codes which, when executed by a computer, performs a method for controlling an internal combustion engine, the method comprising: providing an operating-point-dependent setpoint value of at least one combustion attribute of a combustion in the internal combustion engine on the basis of a setpoint value characteristics map, the combustion attribute corresponding to a variable characterizing the combustion in the internal combustion engine; determining from a control variable characteristics map a value of a characteristics-map-based control variable for controlling the internal combustion engine; ascertaining with the aid of a data-based model a value of a modified control variable for controlling the internal combustion engine, the data-based model ascertaining the value of the modified control variable as a function of a real value of the combustion attribute of the preceding combustion and the characteristics map-based control variable, the real value of the combustion attribute being ascertained by measuring the combustion attribute while the internal combustion engine is in operation, wherein the data-based model is configured to be adaptable as a function of the setpoint value of the combustion attribute and the real value of the combustion attribute; and providing a real control variable to the internal combustion engine to control the internal combustion engine, the real control variable being set to a value that is a function of at least one of the value of the characteristics map-based control variable and the value of the modified control variable.
