  "textContent": "An acquisition unit acquires a required torque and an operating state of an internal combustion engine. A control unit is configured to: control operation of the internal combustion engine by using a required air amount, a required fuel amount, and a required ignition timing; acquire a required air amount by using the acquired required torque and a target air-fuel ratio of an air system determined according to the operating state; perform torque fluctuation correction on the target air-fuel ratio of the air system to determine a target air-fuel ratio of an injection system to reduce a difference between the required torque and an actual torque in a transition period between stoichiometric combustion and lean combustion; acquire a required fuel amount and a required ignition timing by using the determined target air-fuel ratio of the air system and the determined target air-fuel ratio of the injection system.",
