Definitions

  • Electromagnetic actuators consisting essentially of at least an electromagnet and one to be actuated Actuator connected armature exist, when energized of the electromagnet against the force of a return spring is movable, have a high switching speed out.
  • d. H. with getting smaller Air gap between the pole face and the armature, which is on the armature acting magnetic force increases progressively while the counterforce the return spring only grows linearly, so that the anchor with increasing speed on the Pole surface hits.
  • the anchor In addition to the noise, it can this leads to bouncing processes, d. H. the anchor hits first on the pole face, but then lifts at least for a short time until it finally comes fully to the plant. This can impair the function of the Actuator come what is particularly high in actuators Switching frequency can lead to considerable interference.
  • the invention has for its object a control method to create it with an electromagnetic actuator of the type described above, via a Regulation of the energization of the electromagnet the movement of the To guide the anchor so that it has a low impact speed comes into contact with its seat on the pole face.
  • a sufficient holding force after the anchor hits the pole face must be regulated by a suitably regulated holding current can be specified via the control.
  • this object is achieved with a method to control an electromagnetic actuator with at least one electromagnet and one on an actuator acting anchor, against the force of at least one Return spring through controlled energization of the Pole-provided electromagnet via a control device from a first switching position to a second, by the placement of the armature on the pole face defined second Switch position is movable, which is characterized that the anchor path s and the course during the respective switching process the anchor speed v are recorded as actual values, the recorded actual values of anchor travel and anchor speed with a map stored in the control device for a predetermined dependence of the speed on the Flight path of the anchor compared and then a target value for the energization of the electromagnet is predetermined, and that the actual value for the current supply with the target value for the current supply compared and after regulating one out of this resulting difference in electromagnet for armature movement is energized.
  • This procedure takes advantage of the possibility that modern electronic computing modules have a have high computing speed so that it is possible not only the respective position during the switching process and / or speed of movement, but also a plurality of actuators with regard to their movement sequence to record, to process the required movement values and if there are deviations, a corresponding one Control intervention for each individual actuator optimal execution of each switching cycle for each actuator to ensure.
  • a in the Control device stored map in which to generate of the target value for the current supply the required dependency the anchor speed specified via the anchor path and by recording the actual values of the armature movement with regard to Anchor path and speed disruptive factors caused by a Map-dependent change of the setpoint specification for the Current controller and thus the actual value for energizing the "catching" electromagnets and thus the magnetic energy feed can be performed so that the anchor with a Impact speed on the pole face to the system comes that is only slightly above the ideal impact speed "Zero" is.
  • the term "map” in the sense of the invention includes both a single map and a system of maps that are suitable for a variety of operating states be valid.
  • a gas exchange valve GWV for a piston internal combustion engine shown schematically, the with an electromagnetic actuator EMA as valve train is provided.
  • the EMA actuator essentially consists of a closing magnet 2.1 and an opening magnet 2.2, between which an anchor 1 against the force from here only schematically indicated return springs RF1 and RF2 accordingly the current supply to the electromagnet 2 is guided to move back and forth is.
  • the two possible switch positions of the Actuator-forming gas exchange valve GWV are used here by placing the armature on one of the two electromagnets 2 defined.
  • the armature 1 is shown in an intermediate position, after it has been energized by opening the opening magnet 2.2 by the force of the assigned spring RF 2 in the direction of the closing magnet 2.1, d. H. is moved in the direction of the arrow.
  • the movement of the armature 1 is in each case by the energization the magnet 2 controlled. In the movement process shown In the direction of the arrow, this is done via a controller the energization of the catching closing magnet 2.1, so that acts on the armature 1, a magnetic force against the Restoring force of the return spring RF1 on the closing magnet acts after the armature 1 moves through the central position went through.
  • the current is provided by the current regulator 3, the in turn, his commands for energization from an engine control device 4 receives. At least the switch-off signals 5 for the current is passed to the current regulator 3.
  • the actuator is only schematic here shown detection and / or measuring device 7 assigned.
  • the anchor path is detected as a signal in the measuring device 7, whereby this path detection is not necessarily carried out directly Path measurement must take place, but also via a derivative the anchor path can take place from other characteristics, as will be described in more detail below.
  • the Path signal 8 obtained via the measuring device 7 and a signal obtained therefrom speed signal derived via a differentiation 9 10 is supplied to the engine control device 4.
  • the engine control device 4 For processing the path signal 8 and the speed signal 10 is the engine control device 4 with a map or a map system 11 with maps for several actuators provided in which the course of the speed via the anchor path based on empirical knowledge or based on of calculations from the characteristic data of the actuator is.
  • the speed curve over the way is here designed to achieve the desirable low impact speed of less than 0.05 m / s.
  • the map of the predetermined speed curve is a curve assigned for a current target value.
  • the current target value 12 taking into account the recorded actual movement conditions on the actuator using the specified map 11 or a map system of the engine control device itself is corrected, it is possible on the movement behavior of the actuator acting disturbances.
  • the various processes can be used. For example possible by recording the path-dependent Change in the restoring force of the return spring RF1 or RF2 via piezoelectric transducers supporting the return springs RF1 or RF2 are assigned a corresponding one Derive path signal and a speed signal.
  • the electromagnet it is possible to capture the changing direction of the course of the magnetic field lines the changing anchor position and thus the anchor path capture.
  • the electromagnet With an appropriate arrangement that can Main field, but also the stray field of the electromagnet measured and depend on the position of the anchor Changes in the anchor path are derived.
  • end position used here in relation to anchor 1 also applies to the positions that the anchor occupies if the valve is in the presence of a valve clearance Seat reached.
  • the measured or reconstructed variables “path” and “speed” are addressed to a characteristic diagram, from which a current target value is taken directly, in such a way that the optimum current is determined based on a realistic actuator model which enables a touchdown speed of approximately 0.
  • this is done by numerically solving the differential equation system of the actuator model by integrating backwards in time from the moment the armature touches down with a low touchdown speed (point A in the state space).
  • the value range of the current specification is run through in a sufficiently fine gradation, for each sensible speed v j at the path position s i-1 to obtain a current target value that leads safely to the starting point A.
  • An additional quality measure can be used to select an optimal value from several possible current target values.
  • a quality measure can be determined, which is an evaluation of the Map point entries makes.
  • Such a measure of quality can, for example based on what is considered to be particularly useful Trajectory can be determined by the map (the less Deviation from the trajectory, the better the map entry). Or other criteria, such as a current to be changed as little as possible the final map entries are used.
