Abstract

A system and method for controlling intake air flow of an internal combustion engine wherein the response of intake manifold pressure to changes in throttle valve position is controlled in accordance with an engine operating parameter and the gear position of an engine transmission, whereby jerk during acceleration or deceleration can be minimized and engine drivability can be harmonized with engine responsiveness.
