  • Method and apparatus for recognizing knocking of an internal combustion engine, preferably of a gasoline engine
    Patent number: 9625343
    Abstract: In a method for recognizing knocking of an internal combustion engine, solid-borne sound signals are measured and solid-borne sound features are recovered from the measured sound signals. A peak pressure for a combustion event of the internal combustion engine is estimated from the solid-borne sound features, and the estimated peak pressure is compared with a knock recognition threshold, knocking of the internal combustion engine being recognized when the knock recognition threshold is exceeded by the estimated peak pressure.
