Abstract
An object of the present invention is to provide a control apparatus for an electrically assisted supercharger capable of effectively compensating for an output drop even with decrease in the atmospheric pressure. A control apparatus for an electrically assisted supercharger according to the present invention has a superchargerdisposed on an intake passageof an internal combustion enginemounted on a vehicle, and driven by an electric motor, a controllerfor controlling the electric motorto control a boost pressure, and a pressure detectorfor detecting a state of the atmospheric pressure, and is characterized in that when the atmospheric pressure detected by the pressure detectorbecomes less than a predetermined value, the controllermakes a driving force of the electric motorlarger than that when the atmospheric pressure is not less than the predetermined value.
