Patent claim: A method according to any of the previous claims wherein the initial duration of the peak phase TSTART ATduring which the peak control current I is to be supplied to the electromagnetic actuator 22 to control the movement of the component 21 25 moving towards the position defined by the limit stop 26 is chosen among the following possibilitiesthe last value of the duration of the peak phase T during which the electromagnet 24 is to be excited with the peak control current I ora reference initial duration of the peak phase TSTART during which the electromagnet 24 is to be excited with the peak control current I and which is determined in a preliminary set up phase ora weighted mean between the last value of the duration of the peak phase T during which the electromagnet 24 is to be excited with the peak control current I and a reference initial duration of the peak phase TSTART during which the electromagnet 24 is to be excited with the peak control current I and which is determined in a preliminary set up phase ora reference initial duration of the peak phase TSTART during which the electromagnet 24 is to be excited with the peak control current I and which is determined in a preliminary set up phase corrected according to one of the following formulas TjTSTARTjTj1TSTARTj1TjTSTARTjTj1TSTARTj1 whereinTj1 is the last value of the duration of the peak phase T during which the electromagnet 24 is to be excited with the peak control current ITSTARTj1 is the last value of the reference initial duration of the peak phase during which the electromagnet 24 is to be excited with the peak control current I and which is determined in a preliminary set up phase as a function of conditions such as battery voltage V temperature of the winding of the electromagnetic actuator 22 temperature of the fuel used speed of the internal combustion engine ICETSTARTj is the value of the reference initial duration of the peak phase during which the electromagnet 24 is to be excited with the control current I and which is determined in a preliminary set up phase as a function of conditions such as battery voltage V temperature of the winding of the electromagnetic actuator 22 temperature of the fuel used speed of the internal combustion engine ICE.

Related passage: On the other hand if the timing of the pulse is too early or the control current value is too high the pulse may have a negative effect in that the speed of the opening movement of the intake valve may not be only reduced but stopped.It is even possible that the intake valve will due to the pulse of control current be closed again possibly even up to the fully closed position thereby possibly generating a noise when reaching the fully closed position and after shutting off the control current of the pulse the intake valve will start again moving in the opening direction due to the biasing force andor hydraulic force until it reaches the fully open position without any reduction in speed thereby again having a high impact speed and generating a loud noise.Also the valve will in such a situation reach the fully open position at a later time at which the movable plunger may have already an even higher movement speed depending on the cam profile.Then the valve may even reach the fully open position at an even higher impact speed than without applying the deceleration pulse and even generate a louder impact noise.
