Zusammenfassung:	The invention relates to fuel rail pressure control systems and methods. The fuel control system includes a target rail pressure module. The target rail pressure module determines a target fuel rail pressure of a fuel rail of a direct injection engine. An offset module determines an offset value based on an engine speed of the direct injection engine and at least one of an engine load and an air per cylinder. A modifier module determines a modifier value based on a temperature of the direct injection engine. A rail pressure control module adjusts a current fuel rail pressure of the fuel rail based on the target fuel rail pressure, the offset value and the modifier value.
