Abstract
An intake air amount control apparatus is mounted on a vehicle having an automatic transmissionthat switches the shifting pattern for the gear ratio between two modes. The intake air amount control apparatus controls the intake air amount by cooperation of a variable valve lift mechanismthat changes the lift integration value of an intake valveand a throttle valvelocated in an intake passage. When the shifting pattern for the gear ratio is in a sport mode, which gives priority to acceleration performance, the intake air amount control apparatus executes a lift varying control such that the lift integration value of the intake valveis greater than when the shifting pattern is in normal mode, which gives priority to fuel economy.
