Patent ID: 7258090

Claim:
An intake air amount control apparatus for an internal combustion engine mounted on a vehicle provided with an automatic transmission having a gear ratio, in which the engine includes an intake passage and an intake valve having a lift integration value, the intake air amount control apparatus comprising: a throttle valve located in the intake passage of the engine; a variable valve actuation mechanism that changes the lift integration value of the intake valve of the engine; and an electronic control unit that controls intake air amount of the engine, wherein the electronic control unit controls the intake air amount by cooperation of the throttle valve and the variable valve actuation mechanism, wherein the electronic control unit changes the gear ratio of the automatic transmission based on a predetermined parameter representing an operating condition of the vehicle, wherein the electronic control unit is capable of switching a shifting pattern for the gear ratio between a first mode and a second mode, the gear ratio being set higher in the second mode than in the first mode, and wherein, when the shifting pattern for the gear ratio is in the second mode, the electronic control unit controls the variable valve actuation mechanism such that the lift integration value is greater than when the shifting pattern is in the first mode.
