Abstract
A method and device for controlling an internal combustion engine. A first variable is predefined on the basis of a signal of a combustion chamber pressure sensor or a structure-borne noise sensor. This first variable characterizes the combustion process in the combustion chamber of at least one cylinder of the engine. A second variable is read from a characteristics map; a manipulated variable for influencing the combustion process is predefinable from this second variable. The characteristics map and/or the second variable read from the characteristics map are adapted as a function of at least one feature which is determined on the basis of the first variable.
