<P>PROBLEM TO BE SOLVED: To properly correct a fuel injection quantity by a proper learning value. <P>SOLUTION: An engine ECU executes a program including a step (S100) of detecting the air-fuel ratio, a step (S102) of calculating a learning value of a feedback correction quantity of the total injection quantity of fuel calculated on the basis of the air-fuel ratio on a plurality of learning areas divided in response to the suction air volume, a step (S104) of calculating an average value of the calculated learning value, a step (S106) of calculating a guard value on the basis of the average value, and a step (S110) of restricting the learning value larger than the guard value to the guard value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
