ABSTRACT:
A method and a device for the closed-loop control of a control element having integral action, particularly an injection-timing device of a high-pressure fuel pump. Using a system deviation as a baseline, a controller preselects a driving signal to be applied to the control element. In the event of an error in the area of actual-value ascertanment, an emergency travel operation is initiated. A signal is applied to the control element, such that at least short-term, it assumes a defined position.
