Title:
内燃機関におけるノッキング検出時の障害ノイズをフェードアウトさせる方法および装置
Document Type and Number:
Japanese Patent JP2005509111
Kind Code:
A
Abstract:
The present invention creates a method and an apparatus for blanking out interfering noise in connection with detecting knocking in an internal combustion engine. The following functions are performed: Forming a sensor signal integral value (KI) during a measurement time slot (MF) of the sensor signal of a knocking sensor; forming a correction value (DKI) for the sensor signal integral value (KI) corresponding to an interfering noise during the measurement time slot (MF); and subtracting the correction value (DKI) from the sensor signal integral value (KI) for forming a corrected sensor signal integral value (KI') with the interfering noise blanked out.
