Fuel pressure control device for internal combustion engine

A fuel pressure control device for an internal combustion engine, wherein the fuel pressure control device controls a pressure of fuel supplied to a fuel injection valve, and the fuel pressure control device comprises:

• a fuel pump, adopting the internal combustion engine as a driving source, and discharging pressurized fuel to a side of the fuel injection valve;
• a boost control part, performing boost control of setting a fuel discharge amount of the fuel pump to a predetermined value for boosting the pressure of the fuel from a time when cranking starts until a predetermined timing halfway during a startup of the internal combustion engine;
• and
• a limit control part, performing limit control following the boost control, wherein the limit control limits the fuel discharge amount by using an upper limit smaller than the predetermined value.
