Abstract
In a method and a device for the pressure control of a common rail injection system of an internal combustion engine, typically a volume flow control valve regulating mode is carried out. During the performance of the volume flow control valve regulating mode, a pressure control valve regulating mode is activated, if necessary, and temporarily carried out in order to achieve improved pressure control behavior in this way, particularly during dynamic processes.
