摘要： A device for controlling knocking of an internal combustion engine featuring improved reliability by preventing signals of the knocking level from being erroneously detected as those of the noise level. The device detects an ionic current flowing through a spark plug, counts a signal of the knocking level from the ionic current, establishes an average knocking level from the signals of the knocking level and determines a background level from the average knocking level. A comparator judges the knocking state by comparing the signal of the knocking level with the background level. The device calculates the control quantity of the engine based on the operation conditions and the result of judgement of knocking. The device further judges a transient state and decreases the average knocking level depending upon a transience judgment signal in order to maintain a background level in a transient state at an optimum value.
