In a device for controlling an electromagnetic valve, input device(s) write a multitude of measured values for the current and/or the voltage into a first memory to represent a characteristic. Analysis device(s) perform a state analysis and/or a change-over-time analysis. On the basis of the state analysis and/or the change-over-time analysis, evaluation device(s) correct at least one control variable, which characterizes the control, and write it into a second memory. Control device(s) control an output stage on the basis of the control variables.
