<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 determining the DI ratio (r) by linearly interpolating a preset value of the preset DI ratio (r), a step (S102) of calculating a deviation between the determined DI ratio (r) and the preset value, a step (S106) of reducing an updating quantity of a learning value when the deviation between the determined DI ratio (r) and the preset value is larger than a threshold value (YES in S104), a step (S114) of updating the learning value by subtracting the updating value from the learning value calculated last time or adding the updating quantity to the learning value calculated last time when a learning condition is realized (YES in S112), and a step (S116) of correcting the fuel injection quantity on the basis of the learning value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
