Abstract

A device and a method for controlling an internal combustion engine, in which, based on a signal that characterizes the vibrations of an internal combustion engine, at least one feature is determined and used to regulate and/or control operating parameters of the internal combustion engine. In order to generate the feature the signal of a sensor is filtered. Filtering selects low-frequency components of the signal.
