In the knocking avoidance device, the knocking avoidance device comprises: an abnormality determining means for determining whether or not the detection function of each knock detecting means is abnormal based on each detection result of the knock detecting means for each cylinder; and this abnormality determining means. a selection means for selecting the detection result of the knock detection means of a predetermined cylinder in the vicinity of the cylinder in which the knock detection means is installed when the detection function is determined to be abnormal; 1. A knocking avoidance device comprising: abnormality knocking determining means for determining whether knocking occurs in a cylinder provided with the knocking detecting means whose detection function is determined to be abnormal.
