A method and an apparatus for controlling, in particular, an operating parameter of an internal combustion engine. A variable can be defined as a function of an actual value and a setpoint. As a function of the variable, a controller defines a manipulated variable for application to a control element. A microcomputer determines a variable for influencing the response characteristics of the controller, and at least one activation variable for influencing the manipulated variable.

Method and apparatus for controlling a current

A method and an apparatus for controlling an electromagnetic switching member having an excitation winding and a movable armature. A first time point and a second time point define a time window. Within the time window, the current characteristic and/or the voltage characteristic is evaluated in order to detect a switching time point at which the armature reaches a new limit position. The time window is enlarged if no reliable switching time point was detected within the time window.
