Abstract

A method of controlling supercharging pressure in an internal combustion engine by means of a basic control amount dependent upon operating conditions of the engine. A change rate of the supercharging pressure is detected. When the supercharging pressure is in a transient state where it is increasing, the basic control means is corrected in response to the detected change rate of the supercharging pressure, in such a manner that the supercharging pressure increases at a predetermined rate.
