  "textContent": "A control device for an internal combustion engine includes an intake air amount controller and a variable valve controller. The intake air amount controller includes an exhaust manifold pressure calculator, an engine intake air amount calculator, a volumetric efficiency correction coefficient calculator, a cylinder intake air amount calculator, an exhaust gas flow rate calculator, and a cylinder intake air amount controller. The volumetric efficiency correction coefficient calculator calculates a volumetric efficiency correction coefficient based on a pressure ratio between an intake manifold pressure and an exhaust manifold pressure, a rotational speed of the internal combustion engine, and an actuation state of at least one of an intake valve and an exhaust valve.",
