Abstract
A method for determining the movement time curve of an electromagnetically driven armature of an actuator that has a coil may include: (a) applying to the coil a control signal dimensioned such that the armature undergoes only a partial deviation from the armature starting position without reaching an end position defined by a stop, and reaches the armature starting position again after reaching a turnaround position, wherein the deviation of the armature over time is described at least approximately by a section of a parabola at least between the turnaround position and the starting position, (b) determining the time at which the armature reaches the armature starting position again, (c) determining the speed with which the armature reaches the armature starting position again, and (d) ascertaining the movement time curve of the armature using a mathematical equation that describes the parabola based on the detected time and the detected speed.
