ABSTRACT:
An engine ECU executes a program including the steps of: detecting an air-fuel ratio; calculating a learn value of a feedback correction amount for total fuel injection amount calculated based on the air-fuel ratio, for a plurality of learning regions obtained as a result of division corresponding to an intake air amount; interpolating the learn value at an intake air amount different from the intake air amount detected at the time of calculation of the learn value, based on the calculated learn value; and correcting an amount of fuel injection based on the obtained learn value.
