A control device includes a drive unit configured to supply electric power to a fuel injection valve to perform valve open drive to supply fuel to a combustion chamber of an internal combustion engine; and a correction unit configured to correct a fuel injection amount of the fuel injection valve. The correction unit is configured to learn the fuel injection amount of the fuel injection valve when NOx purge is performed to reduce and purify the NOx occlusion catalyst.
