초록

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...
