。[Claims for Utility Model Registration] A knock sensor detects vibrations including the acoustic range of the engine, and the knocking determination level is calculated by smoothing the output of the knock sensor using a predetermined smoothing coefficient for each ignition. a knocking detection device comprising: a knocking determination level calculating means for determining the knocking; and a knocking determining means for determining the occurrence of knocking by comparing the knocking determination level with the output of the knock sensor; and a transient operation detection means for detecting a transient operation of the engine; and a transient operation correction means for correcting the smoothing coefficient of the determination level calculation means to a smaller value during the transient operation. A device for detecting knotting.
