ABSTRACT:
A knocking detecting system comprising a microcomputer with an A/D converter, 4 which receives a frequency signal processed in accordance with the vibration signal of a knock sensor 1. The microcomputer 4 with the A/D converter operates including, at least, the A/D-conversion steps S.sub.1 -S.sub.4 of continuously sampling digital values, the steps S.sub.5 -S.sub.9 of integrating the differences between the digital values and a background level over a detecting period, and the steps S.sub.10 -S.sub.12 of comparing the integrated value with a judgement level, thereby to judge the presence of knocking and to evaluate a knocking level. The signal of the knock sensor 1 is converted into the digital values and is then arithmetically processed by the microcomputer 4. Thus, the knocking is detected, and the background level is calculated at high precision.
