<p>An intake air flow rate detection device for an internal combustion engine (100), including a sensor (61, 63) that detects an operating condition of the internal combustion engine (100), an air flow meter (21) that disposed in the intake passage (20) upstream of the supercharging device (41), and a programmable controller (60) programmed to calculate a measured intake air flow rate from a detection value of the air flow meter (21), calculate a calculated intake air flow rate from the operating condition of the internal combustion engine (100), and employ either the measured intake air flow rate or the calculated intake air flow rate as an intake air flow rate of the intake passage (20) on the basis of an air flow rate of air that is circulated to the intake passage (20) between the air flow meter (21) and the supercharging device (41) through the bypass passage (51).</p> |
