PROBLEM TO BE SOLVED: To inhibit erroneous learning of a long time learning storage for throttle opening learning even in a system with no sensor installed for detecting atmospheric pressure.SOLUTION: In a throttle opening learning arithmetic operation for agreeing a target intake air amount with an actual intake air amount, when using estimated atmospheric pressure in an effective opening area arithmetic operation, a distribution coefficient to long time learning for storing throttle opening learning is calculated according to the estimated atmospheric pressure and an elapsed time after estimation of the atmospheric pressure to inhibit erroneous learning of a long time learning storage. |
