摘要： PROBLEM TO BE SOLVED: To accurately judge whether knocking occurs or not even if noise is detected. SOLUTION: The engine ECU is provided with a waveform detection part 504, a zone identification part 514, and a feedback correction part 700. The waveform detection part 504 detects vibration waveform of a knocking detection gate. The zone identification part 514 identifies two crank angle zones in which change quantity of intensity is larger. A waveform correction part 710 of the feedback correction part 700 corrects vibration waveform according to whether the identified two zones are spaced or adjacent if one of the two identified zones is included in a zone of first half of the knocking detection gate and another is included in a latter half. It is determined whether knocking occurs or not by using the corrected vibration waveform. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To accurately determine an ignition timing for an internal combustion engine. SOLUTION: A 90° integrated value calculating part 608 of an engine ECU calculates such a 90° integrated value lpkknk that strength is totalled. A calculating part 610 calculates knock strength N by dividing the 90° integrated value lpkknk by BGL. A value obtained by subtracting a standard deviation σ from a central value VM for the 90° integrated value lpkknk is determined as the BGL. An ignition timing control part 614 corrects an ignition timing depending on whether the knock strength N is a determined value VJ or greater, or not. A central value calculating part 704 of a feedback part 700 calculates the central value VM for the 90° integrated value lpkknk. A standard deviation calculating part 706 calculates the standard deviation σ from the 90° integrated value lpkknk. A first stop part 800 stops the updating of the central value VM and the standard deviation σ when the 90° integrated value lpkknk is smaller than a first threshold value or a second threshold value or greater.

摘要： PROBLEM TO BE SOLVED: To perform accurate knock determination by reducing an influence of a noise, even when the noise is superimposed on some of vibration waveform components in a plurality of frequency bands extracted from an output signal from a knock sensor.
SOLUTION: The output signal from the knock sensor is filtered with a plurality of band-pass filters to extract vibration waveform components in a plurality of frequency bands fl-f4. Weighting coefficients G1-G4 by which the vibration waveform component in each frequency band is multiplied are established in such a manner as to be a smaller value as a noise intensity of each frequency band becomes larger. Thereby, since the vibration waveform components in the plurality of frequency bands can be synthesized with weighting according to the degree an influence caused by a noise intensity of each frequency band, even when the noise is superimposed on the vibration waveform component in some frequency band, the influence of the noise can be reduced and the vibration waveform component in each frequency band can be synthesized, and accurate knock determination can be performed based on the synthesized vibration waveform.

摘要翻译：要解决的问题：即使当噪声叠加在从爆震传感器的输出信号中提取的多个频带中的一些振动波形分量上时，通过减少噪声的影响来执行精确的爆震确定。解决方案：来自爆震传感器的输出信号用多个带通滤波器进行滤波，以提取多个频带fl-f4中的振动波形分量。每个频带中的振动波形分量相乘的加权系数G1-G4被建立为随着每个频带的噪声强度变大而变小的值。因此，由于可以根据每个频带的噪声强度引起的影响的加权来合成多个频带中的振动波形分量，所以即使当噪声叠加在一些频带的振动波形分量上时，可以降低噪声的影响，并且可以合成每个频带中的振动波形分量，并且可以基于合成的振动波形进行精确的爆震判定。版权所有（C）2009，JPO＆INPIT

SOLUTION: An engine ECU is equipped with an intensity detector 602, a calculator 610, a determination unit 612, an ignition timing controller 614 and a determination value setting unit 700.
