ABSTRACT:
An apparatus and method for controlling the intake air amount in an internal combustion engine provided with a throttle valve and an intake air amount changing means linked with the same, the intake air amount control apparatus and method of an internal combustion engine finding a target intake air amount mcta based on an accelerator opening degree and engine speed (step101), determining a target setting Cvta for said intake air amount changing means based on at least said target intake air amount (step103), and finding a target throttle opening degree θtta based on model equations creating a model of an engine intake system and expressing the air passing through the engine intake system from said target intake air amount mcta and the target setting Cvta (step107).
