Abstract
A control device for an internal combustion engine includes a throttle valve opening degree detector, an air bypass valve controller, and a torque reduction controller. The throttle valve opening degree detector detects an opening degree of a throttle valve which is provided downstream with respect to a compressor of a supercharger. The air bypass valve controller opens an air bypass valve based on a reduction change in the opening degree of the detected throttle valve. The air bypass valve is configured to open and close a bypass path. The torque reduction controller controls the throttle valve to reduce the opening degree of the throttle valve while an automatic transmission connected to the internal combustion engine is in an acceleration shifting in order to execute a torque reduction control. The air bypass valve controller maintains the air bypass valve in a close state during the torque reduction control.
