Abstract

An object of the present invention is to prevent hunting of a throttle in a region in which a throttle upstream pressure and a throttle downstream pressure become substantially equal to each other in an internal combustion engine with a supercharger. For this purpose, a control device for an internal combustion engine with a supercharger provided by the present invention processes a signal of a throttle opening which is calculated by using a formula of throttling when a ratio of the throttle upstream pressure and the throttle downstream pressure has a value close to 1, and controls an operation of the throttle with the throttle opening the change speed of which is lessened as a target throttle opening.
