In order to derive the optimal supercharging pressure, a basic control signal by, which a device which varies the capacity of a turbocharger is controlled, is arranged to increase the supercharge pressure until engine knocking or like undesirable phenomenon occurs, whereafter the throttling provided by the capacity controlling device is incrementally reduced until the phenomenon disappears. Subsequent increases and decreases in the throttling degree holds the supercharge pressure at the optimal level. When acceleration is required, the maximum degree of throttling is induced and held for a time or until an undesirable phenomenon occurs. The hold time may be varied with engine operational parameters such as engine speed.
