Abstract

A device and a method for controlling an internal combustion engine, in particular a diesel engine, are described. Based on the signal from a structure-borne noise detector, parameters are determined which are used to regulate the internal combustion engine. At least one parameter is determined through an analysis that includes a filtering which selects at least two angular ranges.
