摘要： A knock control apparatus equipped with an altitude compensation function is disclosed. The apparatus comprises a knock sensor (100) fittet to an internal combustion engine and detecting the mechanical oscillation of the engine; a background signal detection circuit (201, 202, 204) discriminating the background level signal of the knock signal from the output signal of the knock sensor; a comparator (212) comparing the output signal of the knock sensor with the background signal and detecting knock and the intensity of knock; and a knock control circuit (500) sequentially advancing the ignition timing of the internal combustion engine towards the maximum advance angle position and retarding the ignition timing in accordance with the occurrence of knock and its intensity so as to control and optimize the ignition timing of the engine. The knock control apparatus further includes an atmospheric pressure sensor (700) and changes the maximum advance angle position of the ignition timing in accordance with the output signal of this atmospheric pressure sensor.
