Abstract: To provide a control device of an internal combustion engine in which an accurate output of the internal combustion engine can be obtained, even on the occurrence of a decrease of an opening area of an opening of a throttle valve due to deposition of deposits adhering to the opening of the throttle valve.SOLUTION: A correction function calculation unit is provided for calculating a characteristic curve that determines a correction value every throttle opening on the basis of learning results of a learning value (air-flow rate varying by accumulation of deposits adhering to a throttled part), and thereby a calculated value for each throttle opening calculated on the basis of the characteristic curve is made as the correction value. The correspondence between the throttle opening and the air flow rate is learned, and an adaptation table at the decrease of a passage air flow rate assuming a state of being clogged up most is used about a closing side from the learned opening degree. A learning value of a clogging state is used in the vicinity of the learned opening degree. Also, two adaptation tables at the decrease of the passage air flow rate being close to the value of the learning value are selected about the opening side from the learned opening degree, and the optimal clogging correction can be made using the value obtained by performing interpolation calculation between the learning value and itself.SELECTED DRAWING: Figure 8
