摘要:
An oxygen sensor control apparatus (10) obtains a correction coefficient for calibrating the relation between oxygen concentration and an output value of an oxygen sensor (20), when a fuel cut operation of an internal combustion engine (100) is performed. The apparatus includes average output value calculation means; inter-fuel-cut average output value calculation means; and correction coefficient calculation means.
