Document Type and Number:
Japanese Patent JP4429336
Kind Code:
B2
Abstract:
An air-fuel ratio control apparatus includes a learning unit learning amounts of divergence of a correction amount from a reference value thereof respectively as to a plurality of set lift amount regions as divergence amount learning values, a correction unit calculating a divergence amount correction value and correcting a fuel injection amount command value, and a reflection unit reflecting a learning result of the divergence amount learning value of a specific one of the plurality of the set lift amount regions on the divergence amount learning value of another one of the lift amount regions when there is a history indicating that the divergence amount learning value of the specific one of the lift amount regions has been learned and there is no history indicating that the divergence amount learning value of that another one of the lift amount regions has been learned.
