PURPOSE:To prevent the generation of knocking in area unit and develop the output corresponding to the fuel state in acceleration by setting an area having a high learning frequency as a specific area and setting an area having a low learning frequency as estimated area and renewing the learning value in the estimated area when the variation quantity of the learning value in the specific area is large. CONSTITUTION:An area setting means 12 which sets the area having a high learning frequency out of a plurality of areas as a specific area and sets the area having a low learning frequency as an estimated area and a learning value determining means 11 which determines the new learning value in the estimated area according to the preceding learning value and the feedback quantity adopted as a new learning value when the learning condition for the specific area is satisfied and renews the new learning value in the estimated area by the determined learning value are provided. Therefore, the frequency can be increased into the area having the low learning frequency, and generation of knocking can be prevented in area unit, and the output corresponding to the fuel state can be sufficiently developed in acceleration. |
