CONTROL DEVICE FOR SUPERCHARGED ENGINE |
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. |
