<p>PURPOSE:To absorb the variation of control due to the dispersion of parts or the secular change of an engine even during acceleration by increasing the target supercharged air pressure via the judgement of acceleration and feedback- controlling the supercharged air pressure to the target supercharged air pressure during acceleration based on the detected supercharged air pressure. CONSTITUTION:The intake air quantity is detected with an operational state detecting means 1, the basic control quantity is calculated with a basic control calculating means 3, and the control quantity of an actuator driving an exhaust bypass valve 5 is controlled with a control means 4. During acceleration, an acceleration increment is added to the basic control quantity with a correction calculating means 8. A target supercharged air pressure higher than the normal target supercharged air pressure is set with a target supercharged air pressure setting means 9, the deviation between the detected supercharged air pressure and the target supercharged air pressure is calculated with a deviation calculating means 10. Next, the feedback correction quantity is calculated with a correction is corrected with the correction calculating means 8 based on the feedback correction quantity.</p> |
