Abstract
The controller executes acquisition process for acquiring a parameter correlated with a back pressure which is a pressure in the exhaust pipe upstream of a turbine wheel of the turbocharger, determination process for determining whether the back pressure is higher than or equal to a predetermined pressure based on the acquired parameter, and overlap limitation process for limiting a valve overlap amount between an intake valve and an exhaust valve of the internal combustion engine when it is determined that the back pressure is higher than or equal to the predetermined pressure. The overlap limitation process is a process of changing the valve closing time of the exhaust valve such that the valve overlap amount becomes smaller than that before the overlap limitation process is executed.
