Abstract
Method and apparatus for controlling supercharge pressure for a turbocharger in any of operating zones where proportional control and/or integral control are to be performed and can be selected in accordance with the result of the determination of operation zone determining means and the integral control can be performed only in a predetermined operation zone close to the target supercharge pressure. With this construction, the proportional control is made possible from the zone having a relatively low supercharge pressure and a quick response for the supercharge pressure can be obtained. In addition, a detrimental influence due to early starting of the integral control in the prior art can be avoided.
