Definitions

  • the invention relates to a method for controlling the armature movement of switching magnets, in particular electromagnets for actuators of internal combustion engines.
  • an adaptable control for the inflow and outflow of the working medium is required in order to be able to optimally influence the working process in accordance with the aspects required in each case.
  • the course of the control has a great influence on various parameters, for example the states of the working medium before, in and after the working area, the working frequency and the processes in the working area.
  • the need for adaptable control is particularly given in internal combustion engines, since they work transiently in very different operating states and a correspondingly variable positive control of the gas exchange valves is advantageous.
  • a major problem with electromagnetic controls of this type is to apply the high electromagnetic forces required to actuate the armature connected to the actuator. This leads to a ver relatively high energy consumption and also at an undesirable cost of materials.
  • the invention therefore aims to reduce the energy consumption or the current consumption in switching magnet arrangements of the type described and, accordingly, to achieve material savings.
  • the coil current of the electromagnet is regulated linearly before the expected impact of the magnet armature on the pole face.
  • the coil current of the electromagnet is determined by a two-point control (clocking) before and / or after the magnet armature strikes the pole face of the electromagnet.
  • the coil current of the electromagnet first increases in an unregulated manner up to the value I0 after switching on and then a two-point control (clocking) takes place.
  • the coil current of the electromagnet first increases uncontrolled up to the value I0 after switching on and that a linear regulation then takes place.
  • a constant current can be applied to the electromagnet to determine the impingement of the magnet armature on the pole face, and the point of impingement is then determined as a change in the voltage across the magnet coil.
  • the coil current can be determined again by a two-point control (clocking) after a predetermined time has elapsed after the magnet armature strikes the pole face.
  • electromagnets with soft iron cores instead of electromagnets with soft iron cores, electromagnets with armatures and / or cores made of permanent magnetic material are used additionally or exclusively.
  • a magnet coil 1 of a switching magnet which is connected in parallel with a freewheeling branch indicated by a diode 2, is connected on the one hand to a voltage source 6 and on the other hand to an output stage indicated by a transistor 3.
  • a circuit 5 is also connected to the magnet coil 1, which detects the impact of the magnet armature on the pole face of the electromagnet.
  • the circuit 5 is in turn connected to an output stage control 4, which can, for example, control the coil, as shown in FIG. 2.
  • the current in the coil of the electromagnet initially rises unregulated to the value I0 after switching on on, because the output stage control 4 ensures that the current is switched through in the period from A to B.
  • the current is clocked in the period from B to C between the values I1 and I2.
  • a switchover to linear control takes place, at which the current has the value I3.
  • the circuit 5 is activated in order to detect the impact of the magnet armature on the pole face in the manner indicated.
  • time D which can be the time of impact
  • time E it can be switched back to clocking until E again. It is also possible for the changeover to take place after a predetermined time has elapsed.
  • time E the system is switched off until another working period.
  • the invention offers particular advantages when actuating electromagnets, in particular for actuators on internal combustion engines, in which the time at which the armature strikes is to be detected in order to be able to compensate for influences in production, temperature, supply voltage or the like.
  • the detection of the armature impact usually occurs by evaluating the current dip that occurs when the armature approaches the magnets. However, this requires that the current is essentially only determined by inductance, coil resistance and supply voltage. The current, however, may then rise to values that are actually not necessary for the operation of the actuator.
  • these unnecessarily high currents and thus energy consumption are avoided by limiting the current to a height I0 and regulating it via an energy-saving two-point control (clocking and free-running). Because accurate detection of the When the anchor strike time is extremely difficult, a linear current phase is inserted in the time range of the anchor strike. During this time, the exact time of impact can be identified by evaluating the electrical voltage across the magnetic coil. After detection of the impact, it is possible to switch back to an energy-optimal 2-point control.
  • the main advantage is a particularly energy-saving control, whereby supply voltage compensation and temperature compensation are not necessary.
  • the application of the invention is not limited to electromagnets with soft iron cores, since the use of electromagnets with armatures and / or cores made of permanent magnetic material can also offer advantages.
  • the armature When using permanent magnetic armatures and / or cores, the armature is detached from the pole surface by applying a short countercurrent.
  • the permanent magnet In order to support the tightening process, the permanent magnet generally has to be additionally magnetized; this is done in the same way as for magnets with soft iron core.
