    • The instantaneous interruption detection apparatus includes a noise removing section to remove a noise component from an in-cylinder pressure signal inputted thereto, and output a noise-removed in-cylinder pressure signal, a derivative signal calculating section to calculate a detection signal which is a function of a derivative value of the noise-removed in-pressure signal with respect to the crank angle of an internal combustion engine, an instantaneous interruption determining section configured to make determination that instantaneous interruption of the in-cylinder pressure signal has occurred when the detection signal has exceeded a detection threshold, and a threshold setting section configured to set the detection threshold to such a value that the instantaneous interruption determining section can make the determination in accordance with the noise-removed in-pressure signal which is dull compared to the in-cylinder pressure signal inputted to the noise removing section depending on a gain-frequency characteristic of the noise removing section.
    • 瞬时中断检测装置包括噪声去除部,其从输入的缸内压力信号中除去噪声成分,并输出噪声消除的缸内压力信号;微分信号计算部,计算检测信号为 相对于内燃机的曲柄角的噪声消除的压力信号的微分值的函数;瞬时中断确定部,被配置为当检测到汽缸内压力信号的瞬时中断时已经发生 信号已经超过检测阈值,并且阈值设定部分被配置为将检测阈值设置为瞬时中断确定部分可以根据噪声消除的压力信号进行确定,该噪声消除的压力信号与in 依赖于输入到噪声去除部的气缸压力信号 根据噪声去除部的增益频率特性。
