Abstract
An automobile engine control system estimates a required amount of intake air to be introduced at the end of an intake stroke, based on a change in a factual amount of intake air introduced prior to the end of an intake stroke, and determines a control parameter for controlling engine output based on the required amount of intake air. When the engine operates in a high pulsation range of engine loads, in which pulsation of intake air is at a high level, the determination of the control parameter is based on the required amount of intake air.
