Abstract
When vibration sensed by knock sensor configured to sense the vibration of a multiple cylinder internal combustion engine is greater than a predetermined knock threshold value, a controller performs a first ignition timing control to retard ignition timings of cylinders so that the vibration becomes equal to or smaller than the knock threshold value; previously specifies a specific cylinder relating to a specific vibration due to a bending of a crank shaft; and in a state in which a driving state is in a predetermined specific driving region where there is a possibility that the specific vibration will be generated, when the vibration of the specific cylinder is greater than a predetermined specific vibration judgment threshold value that is smaller than the knock threshold value, performs a second ignition timing control to retard only the ignition timing of the specific cylinder by a predetermined amount.
