Abstract
In the present disclosure, pressurized fuel is directly injected from a fuel injection valve into a cylinder, and a fuel pressure is controlled to a target fuel pressure. A target fuel pressure during early depressurization is calculated on the basis of a target amount of intake air that is a target load of an internal-combustion engine, a target fuel pressure during a normal state is set on the basis of an actual amount of intake air that is an actual load of the internal-combustion engine, and a lower one of the target fuel pressure during early depressurization and the target fuel pressure during a normal state is set as the target fuel pressure.
