ABSTRACT:
An electronic control unit (an ECU) of a fuel injection system performs a learning injection based on a learning injection quantity and obtains multiple influence values of an operating state of an engine generated through the learning injection. The ECU calculates a learning value for correcting the injection quantity in a normal operation based on the multiple influence values. The ECU determines whether the influence value obtained during the learning injection is within a predetermined range of the influence value. The ECU calculates a provisional learning injection quantity for bringing a subsequent influence value into the predetermined range if the influence value obtained in an early stage of the obtainment is out of the predetermined range. Then, the ECU calculates the other influence values by performing the other learning injections based on the provisional learning injection quantity.
