More Information
Summary:In an internal combustion engine control apparatus, an electronic control device is configured to subject a signal from a knock sensor to short-time Fourier transform, to thereby generate an observation matrix. Further, the electronic control device is configured to decompose the observation matrix into knocking vibration data being data on vibration caused by knocking and mechanical vibration data being data on vibration other than the knocking.
