摘要： An air amount estimating apparatus in an internal combustion engine having a supercharger that estimates with high accuracy an amount of air drawn into a cylinder without involving an increased calculation load. The air amount estimating apparatus estimates a cylinder air amount through calculation that incorporates a physical model representing air flowing behavior through an intake path. When, at this time, a ratio of throttle downstream pressure to throttle upstream pressure as calculated with the physical model is smaller than a reference ratio, a throttle flow rate is calculated using an equation of throttle based on the throttle upstream pressure, the throttle downstream pressure, and a throttle opening. When the ratio of the throttle downstream pressure to the throttle upstream pressure is greater than the reference ratio, the throttle flow rate is calculated using a linear interpolation equation based on a compressor flow rate and an intake valve flow rate.

摘要： An object of the present invention is to improve the accuracy of predicting an in-cylinder intake air amount in a control device that predicts an in-cylinder intake air amount of a supercharged engine and controls the supercharged engine based on the predicted value, and particularly the accuracy during transient operation. To achieve this object, the present control device calculates a predicted value of a supercharging pressure based on a predicted value of a degree of throttle opening using a physical model of the supercharged engine, and also calculates a correction amount thereof. When calculating the correction amount, a measurement value of the supercharging pressure measured by a supercharging pressure sensor is acquired, and an estimated value of the supercharging pressure is calculated based on a measurement value of a degree of throttle opening using a physical model of the supercharged engine. A difference between the measurement value and the estimated value of the supercharging pressure is calculated, and the difference is adopted as a correction amount for the predicted value of the supercharging pressure. The present control device calculates a predicted value of the in-cylinder intake air amount based on the corrected predicted value of the supercharging pressure and a predicted value of the degree of throttle opening.
