    • A knock control apparatus for internal combustion engine includes: a knock signal normalization unit that normalizes a knock signal extracted from an output signal of a knock sensor; a knock determination threshold setting unit that sets a knock determination threshold on the basis of the normalized knock signal; a knock intensity computation unit that calculates knock intensity on the basis of the normalized knock signal and the set knock determination threshold; a knock determination unit that determines a presence or absence of a knock on the basis of the calculated knock intensity; and a knock correction amount computation unit that calculates a knock correction amount to correct the calculated knock intensity in a case where an occurrence of a knock is determined. The knock signal normalization unit normalizes a standard deviation of the knock signal by dividing the knock signal by an average value of the knock signal.
    • 用于内燃机的爆震控制装置包括:敲击信号归一化单元,其对从爆震传感器的输出信号提取的爆震信号进行归一化; 爆震判定阈值设定单元,其基于归一化爆震信号设定爆震判定阈值; 敲击强度计算单元,其基于所述归一化爆震信号和所述设定爆震判定阈值来计算爆震强度; 敲击判定单元,其基于所计算的爆震强度来确定爆震的存在或不存在; 以及敲击校正量计算单元,其在确定敲击的发生的情况下计算敲击校正量以校正所计算的敲击强度。 敲击信号归一化单元通过将爆震信号除以爆震信号的平均值来标准化爆震信号的标准偏差。

    • Knocking control is performed using a data group of serial segments each including a predetermined number of values obtained by A/D-converting a signal that appears within a knocking detection window and a data group consisting of serial segments each including the predetermined number of values. The starting timing is shifted and a time-frequency analysis is applied to the data groups in a plurality of frequency bandwidths. Peak values and integration values of spectrums, within the knocking detection window, outputted after the time-frequency analysis in each of the frequency bandwidths are calculated. A P/H method is performed based on the peak value in each of the frequency bandwidths and an integration method is performed based on the integration value in each of the frequency bandwidths for a knocking determination. If knocking is detected through at least one of the methods, the ignition timing is delayed in order to avoid the knocking.
    • 使用串行数据的数据组进行敲击控制,每个数据组包括通过A / D转换出现在爆震检测窗口内的信号获得的预定数量的值,以及由包括预定数量值的串行段组成的数据组。 开始定时被移位,并且在多个频率带宽中对数据组应用时间 - 频率分析。 在每个频率带宽中的时间 - 频率分析之后输出的爆震检测窗口内的频谱的峰值和积分值被计算。 基于每个频率带宽中的峰值执行P / H方法,并且基于用于敲击确定的每个频率带宽中的积分值来执行积分方法。 如果通过至少一种方法检测到爆震,则点火正时被延迟以避免爆震。
