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 supercharger 20 disposed on an intake passage 5 of an internal combustion engine 1 mounted on a vehicle, and driven by an electric motor 20a, a controller 16, 21 for controlling the electric motor 20a to control a boost pressure, and a pressure detector 30 for detecting a state of the atmospheric pressure, and is characterized in that when the atmospheric pressure detected by the pressure detector 30 becomes less than a predetermined value, the controller 16, 21 makes a driving force of the electric motor 20a larger than that when the atmospheric pressure is not less than the predetermined value.

Abstract: A control apparatus for an internal combustion engine has a supercharger connected to an intake passage of the internal combustion engine and driven by a motor, a bypass passage which is provided for the intake passage in such a manner as to bypass the supercharger, flow amount adjustment device which arbitrarily adjusts a flow amount of air flowing through the bypass passage, and controller which controls the motor and the flow amount adjustment device. The flow amount adjustment device is electrically driven. The controller stops the supercharger from performing supercharging after driving the flow amount adjustment device and starting suction of air via the bypass passage.

Abstract: A control apparatus for an internal combustion engine in accordance with the invention includes a supercharger, a bypass passage, a flow amount adjustment device, an operational state detection portion, and a driving time determination portion. The supercharger is connected to an intake passage of an internal combustion engine and is driven by a motor. The bypass passage is provided for the intake passage in such a manner as to bypass the supercharger. By being driven electrically, the flow amount adjustment device can arbitrarily adjust a flow amount of air flowing through the bypass passage. The operational state detection portion detects an operational state of the internal combustion engine. The driving time determination portion determines a time at which the flow rate adjustment device is driven based on a result of detection performed by the operational state detection portion.
