Throttle valve control device for internal-combustion engine

摘要

A throttle valve control device in an internal-combustion engine having an electronically-controlled throttle valve is provided for calculating a final target opening based on an engine operation state, which includes an accelerator depression amount, and an ISC request opening for adjusting a revolutional speed of the engine to a target revolutional speed during an idling operation, and for electronically controlling the throttle valve so as to adjust the throttle valve opening to the final target opening. The device of the present invention includes a correction section for correcting the ISC request opening based on an amount of variation in the revolutional speed of the engine when the final target opening is identical to the ISC request opening, while prohibiting the correction of the ISC request opening when the final target opening is not identical to the ISC request opening.
