PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of estimating accurate atmospheric pressure even if irregularities or the like between throttle devices are present.SOLUTION: A control device for an internal combustion engine includes atmospheric pressure estimating means which has: effective opening area calculating means 21 for calculating an effective opening area corresponding to a throttle opening; throttle opening learning value calculating means 22 for calculating a learning value on a relationship between the effective opening area and the throttle opening; error variation calculating means 23 for calculating error variations from the error occurring in the relationship after correction by using the learning value; error variation range determination means 24 for determining if the error variation is present in a predetermined range; atmospheric pressure estimation value updating means 26 for updating an atmospheric pressure estimation value; and a target throttle opening calculating section 27 for calculating a target throttle opening by using the updated atmospheric pressure estimation value. With this configuration, the atmospheric pressure estimating means controls the throttle opening to reach the target throttle opening. |
