摘要： A method of activating an electromagnetic actuator having at least one coil and a movable armature. The method includes the step in which the electromagnetic actuator is demagnetized by passing a sequence of electric current pulses with a current flow direction which alternates from one current pulse to the next and with a current size which decreases from one current pulse to the next, through the at least one coil, in order to reduce or eliminate any residual magnetic flux density in the electromagnetic actuator. The method also includes a step in which a position of the movable armature is determined, after the demagnetization step, by passing a measurement current pulse through the at least one coil.
