Abstract
A controller for an internal combustion engine defines a difference between a throttle opening degree target value before correction and a throttle opening degree target value after correction as a correction amount. The difference between a downstream pressure that is a pressure downstream of a throttle valve in the intake passage and a required value of the downstream pressure is defined as a pressure difference. The controller corrects the throttle opening degree target value so that the correction amount increases as the absolute value of the pressure difference increases, the correction amount is smaller when the throttle opening degree is large than when the throttle opening degree is small, and the correction amount is smaller when the flow velocity of intake air in the intake passage is low that when the flow velocity of the intake air is high.
