Abstract:
1. A control device for an internal combustion engine having an intake passage and a throttle valve arranged in the intake passage, the control device comprising: target air amount calculating means for calculating a target value of an intake air amount; target throttle opening calculating means for calculating a target throttle opening required for making the actual intake air amount equal to the target intake air amount; setting means for calculating a convergent throttle opening and setting a final target throttle opening to the convergent throttle opening when the engine steady operation is in process, the convergent throttle opening being a throttle opening to which the actual throttle opening converges assuming that the target intake air amount is kept at the target intake air amount calculated by the target air amount calculating means; and driving means for driving the throttle valve so that the actual throttle opening is made equal to the final target throttle opening.
