Method and apparatus for the fade-out failure of knocking noise detection in an internal combustion engine

摘要

The present invention provides an apparatus and failure noise fade-out way of knocking detection in an internal combustion engine. The following functions are performed here, ie: to form the sensor signal integration between the value of (MF) time measurement window of the sensor signal of the knock sensor (KI); correction value value integral signal sensor with respect to the (KI) (DKI formed correspondingly failure noise during the measurement time window (MF) a); in order to form a sensor signal integral value of the modified noise interference is fading out (KI `), and sensor corrected value (DKI) I subtract value from the signal integration (KI).
