ABSTRACT:
A method and apparatus for calculating a target torque of an engine in accordance with operation condition of a vehicle, calculating a target intake air amount per engine revolution cycle required to generate the target engine torque, calculating an opening of a sub throttle valve disposed in an intake path of the engine from an opening of a main throttle valve disposed in the intake path, of which an opening is controlled in accordance with an operation amount of an accelerator pedal, and the target intake air amount, or calculating an equivalent throttle opening assuming the main throttle valve and the sub throttle valve as an equivalent throttle valve in accordance with the target intake air amount, calculating the sub throttle valve opening by correcting the equivalent throttle opening with a correction coefficient determined by the relationship between the equivalent throttle opening and the main throttle valve opening, and on/off controlling the sub throttle valve in accordance with the calculated sub throttle valve opening.
