Abstract:
A control method for an internal combustion engine, the internal combustion engine including a valve timing control mechanism on at least an intake side and configured to control an operation of the valve timing control mechanism on the intake side during acceleration, the method including, calculating a relational expression between an intake valve timing, the intake valve timing being an operation timing of an intake valve, and a cylinder air charge amount in a range in which the intake valve timing can be advanced or retarded within a predetermined calculation cycle from a current value, calculating a target air charge amount, the target air charge amount being a target value of the cylinder air charge amount during the acceleration, based on an operating state of the internal combustion engine, calculating a target value of the intake valve timing corresponding to the target air charge amount from the relational expression for each calculation cycle, and setting a command signal for the valve timing control mechanism on the intake side based on a calculated target value of the intake valve timing.
