PROBLEM TO BE SOLVED: To properly purge an evaporation fuel and execute learning control while preventing hunting in purging.SOLUTION: A control device (100 ) of a vehicle (10) includes: a learning means (102) for executing learning control for making an actual air-fuel ratio follow a target air-fuel ratio in each of a plurality of learning regions divided according to an index value indicative of an operating state of an internal combustion engine; and a setting means (103) for setting a target operation line of the internal combustion engine according to the concentration of an evaporation fuel when the index value is located near a boundary between a learning completion region and a learning incompletion region. The setting means sets the target operation line to a first operation line corresponding to the learning completion region (i) when the concentration of the evaporation fuel is higher than predetermined concentration (THI), and sets a second operation line corresponding to the incompletion region (ii) when the concentration is not higher than the predetermined concentration. |
