摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. It is judged whether the target throttle opening can be realized by a step motor. A final target throttle opening is set to a maximum or minimum throttle opening which can be realized by the step motor when it is judged that the calculated target throttle opening cannot be realized by the step motor. The step motor drives the throttle valve so that the actual throttle opening is made equal to the final target throttle opening, and the intake pipe pressure is estimated on the basis of the final target throttle opening.

摘要： A target value of an engine load ratio is calculated. A target throttle opening required for making the actual engine load ratio equal to the target engine load ratio is calculated on the basis of an intake pipe pressure which is a pressure in the intake passage downstream of the throttle valve. A convergent throttle opening, which is a throttle opening to which the actual throttle opening converges assuming that the target intake air amount is kept at the calculated target intake air amount, is calculated. A final target throttle opening is set to the target throttle opening when the engine transient operation is in process, and to the convergent throttle opening when the engine steady operation is in process. Then, the throttle valve is driven so that the actual throttle opening is made equal to the final target throttle valve.

摘要： An intake passage upstream of a throttle valve is divided into a plurality of intake divided-flow conduits, and air flow meters are arranged in the respective intake divided-flow conduits. The throttle opening is obtained, and a throttle valve passing-through air amount, which is an amount of air passing through the throttle valve, is calculated on the basis of the throttle opening. Each air flow meter-detecting intake air amount, which is an intake air amount to be detected by the air flow meter, assuming that air flows through each intake divided-flow conduit by a part of the throttle valve passing-through air amount, the part being determined by a divided-flow ratio of the corresponding intake divided-flow conduit, is estimated, and a total value of the estimated air flow meter-detecting intake air amounts is then estimated. The engine is controlled on the basis of the total air flow meter-detecting intake air amount.

摘要： In an internal combustion engine wherein a valve timing can be changed in at least two stages and wherein an exhaust gas recirculation passage provided with a control valve is connected to an intake pipe downstream of a throttle valve, there is provided an intake air amount estimation apparatus that estimates, on the basis of an intake pipe pressure, an amount of intake air drawn via the throttle valve. An amount of recirculated exhaust gas flowing past the control valve having a specific opening degree based on an intake pipe pressure in the case of the first valve timing is calculated as an intake exhaust gas amount. On the assumption that this intake exhaust gas amount remains unchanged irrespective of a valve timing, an intake air amount in the case of the second valve timing is calculated.
