Abstract

PURPOSE:To improve the stability and the responsiveness of the average of the knocking intensity values by providing an update quantity setting means which sets the update quantity per one averaging operation of an averaging means for the knocking intensity values to a greater value for the specified period after the engine state satisfies the specific requirements. CONSTITUTION:A detecting means B detects knocking intensity values from the outputs of a knocking sensor A and the knocking intensity values are averaged by an averaging means C. Based on the average of the knocking intensity values, a knocking decision level generating means D generates a knocking decision level and based on said decision level, a knocking decision means E decides the occurrence of a knocking. And according to the result from the decision, a knocking control means F controls a knocking control factor. In this case a decision means H decides whether or not the specified time passed after the engine state detected by an engine state detecting means G satisfies the specific requirements and if the satisfaction is made within the specified period, the update quantity per one averaging operation of the averaging means C is set higher by an update quantity setting means I.
