CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To improve followability and convergence of an actual air amount to a target air amount in acceleration by suppressing interference between an intake pipe pressure control using a supercharging characteristic control actuator and an intake amount control using a VVT (variable valve timing mechanism).SOLUTION: A base VVT control variable as a basic control variable of a VVT is calculated on the basis of a target air amount. A final VVT control variable as a final control variable of the VVT is calculated by correcting the base VVT control variable according to a condition of an internal combustion engine or a condition of the VVT. The VVT control variable corresponding to the smaller air amount of the base VVT control variable or the final VVT control variable is selected, and an actuator control variable as a control variable of a supercharging characteristic control actuator is calculated on the basis of the selected VVT control variable and the target air amount. A control device controls the VVT according to the final VVT control variable, and controls the supercharging characteristic control actuator according to the actuator control variable.
