Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2022114011
Kind Code:
A
Abstract:
To provide a control device for an internal combustion machine capable of more accurately calculating an effective opening area of a throttle valve while suppressing an increase in development man hours and pressure on a storage region.SOLUTION: An ECU 200 includes: a deposit learning determination section 203 determining whether to allow throttle valve effective opening area learning on the basis of a pressure difference between a throttle valve upstream pressure estimation value and atmospheric pressure; an actual effective opening area calculation section 204 calculating an actual effective opening area that is a true throttle valve effective opening area on the basis of the atmospheric pressure, an ambient temperature, throttle valve downstream pressure and an intake air flow rate; a model effective opening area calculation section 206 calculating a model effective opening area that is a prediction value of the throttle valve effective opening area on the basis of a throttle valve opening and correcting the model effective opening area on the basis of effective opening area correction amount; and an effective opening area correction amount calculation section 205 calculating the effective opening area correction amount on the basis of a difference between the actual effective opening area and the model effective opening area.SELECTED DRAWING: Figure 3
