Method for detecting the motion and position state of a component of an inductive electric load, which component can be moved between two end positions by means of magnetic interaction

A method for detecting an instantaneous motion and position state of a movable inductive electric load component which is moved between two end positions by magnetic interaction, comprising the steps of:

• dividing the total waveform of the drive current of the inductive electric load into a plurality of states which characterize the instantaneous motion and position state of the movable component;
• determining a parameter set from at least two parameters assuming binary values, in which a first parameter of the two parameters characterizes a setpoint value of the drive current, the first parameter being the value 1 when the inductive electric load starts to move out of its rest position and being the value 0 when the inductive electric load is at rest and in which the second parameter characterizes a direction of change of the drive current to determine if the drive current is increasing or decreasing the second parameter being the value 1 when the drive current increases and being the value 0 when the drive current is constant or decreasing;
• evaluating the change in direction of the drive current as a function of the set point value of the drive current if the inductive electric load is in motion;
• and
• transitioning from a first motion and position state of the inductive electric load into a second motion and position state of the inductive electric load when the values of the parameters the parameter set change
