Beschreibung
Zusammenfassung:	Proposed is a method for closed loop rail pressure control of a V-type internal combustion engine with an asymmetrical firing order, wherein an actual rail pressure is computed from the measured rail pressure; a system deviation is determined by means of the actual rail pressure and a set rail pressure; and wherein a correcting variable for actuating a pressure actuating element, in particular a suction throttle, for regulating the rail pressure is computed. The invention is characterized by the fact that the actual rail pressure is computed from the measured rail pressure by means of an averaging filter in that below a limit speed (nLi) the rail pressure is averaged over a constant time and in that above the limit speed (nLi) the rail pressure is averaged over a working cycle of the internal combustion engine.
