- the sensors assigned to the control device 3 are designed as a first ammeter 34, the one Actual value I_AV1 of the current through the first coil is detected, or its second ammeter 35, which has an actual value I_AV2 of Current detected by the second coil 115.
- Sensors can also have other sensors.
- the control device further comprises a control unit 31 and a first power output stage 32 and a second power output stage 33.
- the control unit 31 generates depending on control commands the higher-level control device and depending on the actual values I_AV1, I_AV2 of the current through the first and the second coil 113, 115 control signals for the control lines L1, L2, L3, via which the control unit 31 is electrically conductive is connected to the first output stage 32, and control signals for the control lines L1 ', L2', L3 ', via which the control unit 31 electrically conductive with the second output stage 33 connected is.
- the first and second power output stages 32, 33 differ only in that the first power stage 32 for driving the first coil 113 and the second power output stage for driving the second coil 115 are provided. The circuit arrangement and mode of operation their components are equivalent.
- the first power stage 32 ( Figure 2a) has a first transistor T1, the gate terminal of which Control line L1 is electrically connected, one second transistor T2, whose gate terminal is electrically conductive is connected to the control line L2, and a third Transistor T3, whose gate connection is electrically conductive is connected to a control line L3.
- the first power stage 32 also includes diodes D1, D3, D4, a free-wheeling diode D2 is an electrical capacitor Energy storage and a resistor R, which acts as a measuring resistor is provided for the ammeter 34.
- the first Power output stage can be in five different operating states BZ1 can be controlled, which are each characterized by the respective switching state of the transistors T1, T2, T3.
- the five operating states BZ1 are in Figure 2e with the associated switching states of Transistors T1, T2, T2 applied.
- the five operating states BZ1 are an idle state RZ, normal energizing NB, free running FL, fast current withdrawal SSR and fast energizing SB.
- the Operating states BZ1 of the power output stage 32 are as follows explained in more detail with reference to FIGS. 2a to 2d.
- the transistors T1, T2, T3 are all non-conductive.
- the actual value I_AV1 of the current through the first coil is zero and the voltage drop U L at the first coil is also zero.
- the transistors T1 and T2 are operated in a conductive (ON) and transistor T3 are operated in a non-conductive (OFF) manner.
- Current then flows from a voltage source with the potential of the supply voltage U B through the transistor T1, the diode D1, the connection AL1 of the first coil 113, through the first coil 113 to the connection AL2 of the first coil 113, through the transistor T2 and the resistor R to a ground connection that is at a reference potential.
- the current increases in accordance with the ratio of the voltage drop UL across the first coil 113 and the inductance of the first coil 113.
- the transistor T2 In the operating state of the freewheeling device FL, the transistor T2 is operated in a conductive state (ON), the transistors T1, T3, however, are not operated in a conductive state (OFF). If a current flows from the connection AL1 through the first coil 113 to the connection AL2 at the time of the transition into the operating state of the freewheel FL, the freewheeling diode D2 becomes conductive and the current through the first coil 113 increases depending on the losses in the coil 113 , in the transistor T2, the resistor R and the freewheeling diode D2. The voltage drop U L at the first coil 113 is then given by the forward voltages of the freewheeling diode and the transistor T2 and the voltage drop across the resistor R (a total of, for example, 2 volts).
- the transistors T1, T2 and T3 are operated in a non-conductive manner. If a current flows through the first coil 113 during the transition into the operating state BZ1 of the rapid current reduction SSR, the freewheeling diode D2 and the diode D3 become conductive. The current then flows from the reference potential via the freewheeling diode D2 to the connection AL1 of the first coil 113 and then through the first coil 113 to the connection AL2. From there, the current flows through the diode D3 to the capacitor C and charges it.
- the current through the first coil decreases in the operating state of the rapid current reduction SSR much faster than in the operating state BZ1 of the freewheeling FL, since the negative supply voltage U B at the first coil 113 is reduced by the voltage drop U C across the capacitor C and the forward voltages the freewheeling diode D2 and the diode D3 drop.
- the first coil 113 and the capacitor C form a first resonant circuit.
- the first transistor T1 is operated in a non-conductive manner (OFF) and the transistors T2 and T3 are operated in a conductive manner (ON).
- Current flows from the voltage source via the capacitor C, which is thereby discharged, the transistor T3 to the connection AL1 of the first coil through the first coil to the connection AL2 of the first coil 113 through the transistor T2 and the resistor R to the reference potential ,
- the voltage drop U L at the first coil 113 is equal to the sum of the supply voltage U B and the voltage drop U C at the capacitor C reduced by the forward voltages of the transistors T2 and T3 and the voltage drop across the resistor R.
- the voltage drop U L at the first coil 113 is then, for example, approximately 80 V at a supply voltage U V of approximately 42 V.
- the increase in the current through the first coil 113 is then approximately twice as high as if only the supply voltage U B were present the first coil 113 drops.
- a diode D4 is connected in parallel with the capacitor C, this ensures that the voltage potential at the drain terminal of the transistor T3 does not fall below the supply voltage U B by more than the forward voltage of the diode D4.
- FIG. 3 shows the first and second power output stages 32, 33 in one embodiment, in the two power output stages 32, 33 a common capacitor C is assigned.
- This Embodiment has the advantage that only one capacitor is provided, whereby the power output stages as a whole are inexpensive, and the capacitor C in an operating state Z1 of the first power output stage 32 of the fast one Current withdrawal SSR can be loaded, and then in an operating state BZ2 of the fast energization SB of the second Power output stage 34 can be discharged again. This vice versa is also possible.
- the reference numerals of the first Power output stage 32 corresponding elements of the second Power output stage 33 are each provided with a "'".
- FIG. 4 shows a flow diagram of a first program, that is processed in the control unit 31.
- the program is started in a step S1. It becomes the current one Target position of the anchor plate 116 read in by the higher-level control device is specified.
- Step S2 is checked whether the target position of the Anchor plate 116 since the last call of the first program the closed position S has changed to the open position O. If this is the case, the first power output stage becomes step S3 32 in the operating state BZ1 rapid current withdrawal SSR controlled. The first power stage 32 goes into the operating state BZ1 of the idle state RZ as soon as the current through the first coil 113 becomes zero.
- the first program is then ended in step S5.
- step S7 checked whether since the last call of the first Program a transition from the target position of the anchor plate 116 from the open position O to the closed position S. is. If this is the case, the first step is S8 Controller R1 activated.
- the controlled variable of the first controller R1 is the current through the first coil 113.
- a setpoint I_SP1 of the current through the first coil 113 becomes a catch value I_F assigned.
- a control difference RD is calculated from the Difference between the setpoint I_SP1 and the actual value I_AV1 of the Current through the first coil 113.
- the first regulator is R1 preferably designed as a two-point controller.
- the first regulator R1 controls the first output stage 32 depending on the control difference RD either in the operating state BZ1 of the normal current supply NB or the freewheel FL. Controller R1 remains activated until a predetermined condition is met, the one Signs of anchor plate 116 striking the first Contact surface 115a is.
- the specified condition can for example, be that the anchor plate a predetermined position has reached or exceeded. This predetermined position is chosen so that it is very close to the Close position S is.
- step S9 in which the first Controller is reactivated, the setpoint I_SP1 of the Current through the first coil 113 an increased hold value I_HE is.

- the first controls Controller in step S9 the first power output stage 32 first in the operating state of the rapid current supply SB, until the actual value I_AV1 of the current through the first coil is larger than the increased hold value I_HE, and / or in the operating state of normal energization as soon as the capacitor C discharges until the actual value I_AV1 of the current through the first coil is larger than the increased holding value I_HE.
- the processing is continued in a step S10.
- step S10 the first controller R1 is activated
- the setpoint I_SP1 of the current through the first coil 113 is Hold value I_H and the controller controls the first power stage 32 depending on the control difference RD either in the State of the operating state BZ1 of the normal current NB or the freewheel FL until a transition from the target position of the anchor plate from the closed position S to the open position O.
- the processing of the program in the Step S5 ends.
- step S11 in which it is checked whether the target position of the anchor plate 116 is the closed position S or whether the capacitor C is charged to a predetermined value. Checking whether the capacitor C is charged to the predetermined value can be carried out particularly simply by evaluating a counter which is incremented each time step S13 is processed and which is reset in step S8. It is advantageous if a sensor is provided which detects the voltage drop U C across the capacitor C and the charge on the capacitor C is determined from the detected voltage drop U C. If the condition of step S11 is met, the first controller R1 remains active as in step S10 if the target position of the anchor plate 116 is the closed position S, and the first program is ended in step S11.
- step S13 in which the first power output stage 32 is controlled into an operating state BZ1 of the normal current supply NB, either for a predetermined period of time or until the actual value I_AV1 of the current through the first coil 113 has reached a predetermined value.
- the power output stage 32 is then controlled in a step S14 in the operating state BZ1 of the rapid current reduction SSR.
- the capacitor C can thus simply be charged while the first coil 113 is not energized to catch or hold the armature plate 116.
- the processing of the program is then ended in step S5.
- the first program is called cyclically, either at predetermined intervals or after a predetermined Change in the crankshaft angle. While the target position anchor plate 116 is the open position O thus the first power stage 32 once in step S3 in the operating state BZ1 of the rapid current withdrawal SSR and several times in step S14 the operating state BZ1 controlled rapid current withdrawal and thus the capacitor C within a predetermined period of time to the predetermined Value loaded.
- the first coil 113 in the step S8 is controlled in the operating state of the freewheel as soon as the energy required to reach the closed position S. the anchor plate has been fed.
- the coil first 113 is then in freewheeling FL when the specified condition is met which is a sign of the impact of the anchor plate 116 onto the first contact surface 115a.
- FIG. 5 A flow chart of a second program for controlling the second coil 115 is shown in Figure 5, which in the Control unit 31 is processed.
- the second program has the same structure as the first program ( Figure 4). in the The following are just the differences from the first program described.
- step S2 is checked whether the target position the anchor plate 116 since the last call of the first program the open position O changed to the closed position S. Has. If this is the case, then in a step S3 ' second power stage 34 in the operating state BZ2 controlled SSR rapid current withdrawal. The second power stage 34 goes into the operating state BZ2 of the idle state RZ over once the current through the second coil 115 becomes zero becomes.
- step S7 If the condition of step S2 'is not fulfilled, then in a step S7 'checked whether since the last call of the second program a transition of the target position of the anchor plate 116 from the closed position S to the open position O is done.
- a second controller R2 is activated, whose controlled variable is the current through the second coil 115.
- a control difference RD ' is calculated from the difference of Setpoint I_SP2 and the actual value I_AV2 of the current through the second coil 115.
- the second regulator R2 is preferably as Two-point controller designed. The second controller R2 controls the second output stage 33 depending on the control difference RD 'accordingly how the first controller R1 controls the first output stage.
- the controller R2 remains activated in step S8 'until one predetermined condition is met, which is an indication of a Impact of the anchor plate 116 on the second contact surface Is 115b.
- step S7 ' If the condition of step S7 'is not met, then the processing continues in a step S11 'in which checked whether the target position of the anchor plate 116 is the open position Is O or whether the capacitor C is at a predetermined Value is loaded.
- step S11 ' If the condition of step S11 'is not met, then the processing is continued in a step S13 ', in which the second power output stage 33 in an operating state BZ1 des Normal energizing NB is controlled, either for the predefined period of time or until the actual value I_AV2 of the Current through the second coil 115 reaches a predetermined value Has.
