Internal combustion engine controlling method, involves filtering signal characterizing engine vibrations using low pass filter to select low frequency components of signal for forming characteristic used for control of operation parameters

摘要

The method involves retrieving characteristics used for the regulation and/or control of operation parameters of an internal combustion engine, from a signal, of a sensor, characterizing the vibrations of the engine. The vibrations characterizing signal is filtered by a low pass filter to form the characteristic. The filtering selects low frequency components of the signal. An independent claim is also included for a device for controlling an internal combustion engine.
