Internal combustion engine output control method and system
The invention is directed to the improvement of starting performance in an engine rotational speed region that exceeds an idle rotation region without affecting normal traveling performance. At the time when a vehicle starts moving, when in an electronic control unit, the rotational speed of an engine is in a predetermined range that exceeds an idle rotation region and the engine rotational speed decreases, the electronic control unit adds a corrected fuel injection amount corresponding to the rate of decrease to a target fuel injection amount to create a new target fuel injection amount. When the rotational speed of the engine increases, the electronic control unit subtracts a corrected fuel injection amount corresponding to the rate of increase of the engine rotational speed from a target fuel injection amount to create a new target fuel injection amount. Control of the output of the engine is performed by the electronic control unit.
