摘要：Disclosed is an atmospheric pressure estimation device that estimates theatmospheric pressure to be applied to the calculation of control parameters for internalcombustion engines. An estimated airflow passing an intake throttle valve is calculatedbased on the estimated atmospheric pressure, detected intake air pressure, and airintake throttle valve opening, and the estimated atmospheric pressure is updated so thatthe estimated airflow passing the intake throttle valve matches the detected airflowpassing an intake throttle valve. The estimated airflow passing an intake throttle valve iscalculated using the updated estimated atmospheric pressure. Updating of theestimated atmospheric pressure and calculation of the estimated airflow passing thethrottle valve are successively executed, wherein the estimated airflow passing thethrottle valve is subject to the intake airflow, and the estimated atmospheric pressure issubject to the atmospheric pressure.
