A detecting device detects boost condition of each of a plurality of superchargers. The detecting device includes at least two of a pressure ratio detecting unit, which detects the ratio of the pressure downstream each supercharger to the pressure upstream each supercharger; an air flow rate detecting unit, which detects the flow rate of air passing through each supercharger; and a rotational speed detecting unit, which detects the rotational speed of each supercharger. When it is determined that the boost condition of only part of the superchargers is w...
The invention claimed is: 1. A supercharge control apparatus for an internal combustion engine, wherein the internal combustion engine includes a plurality of superchargers, and air fed from the superchargers are combined and supplied to the internal combustion engine, the apparatus comprising: a detecting device for detecting boost condition of each of the superchargers, the detecting device including at least two of a pressure ratio detecting unit, which detects the ratio of the pressure downstream each supercharger to the pressure upstream each super...
