Abstract
A method and a device for controlling an internal combustion engine, in particular a diesel gasoline engine. The output signal from at least one structure-borne noise sensor is supplied to at least one first and one second filter means, which exhibit different response characteristics. On the basis of the output signals from the filmer means, at least two quantities that characterize the combustion and/or the injection in the internal combustion engine are able to be determined.
