- An intake port 22 and a cylinder 23 with a piston 24 are assigned to the cylinder head 21.
- the piston 24 is coupled to a crankshaft 26 via a connecting rod 25.
- a control device 3 which detects signals from sensors and / or detects signals from a higher-level control device (not shown) for engine operating functions and generates actuating signals, depending on which the first and second coils 113, 115 of the actuating device 1 are controlled.
- the sensors which are assigned to the control device 3 are designed as a first ammeter 34, which detects an actual value I_AV1 of the current through the first coil, or its second ammeter 35, which detects an actual value I_AV2 of the current through the second coil 115. In addition to the sensors mentioned, other sensors can also be present.
- 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 from the higher-level control device and depending on the actual values I_AV1, I_AV2 of the current through the first and second coils 113, 115 Control signals for the control lines L1, L2, L3, via which the control unit 31 is electrically conductively connected to the first output stage 32, and control signals for the control lines L1 ', L2', L3 ', via which the control unit 31 is electrically conductive to the second output stage 33 is connected.
- the first and second power output stages 32, 33 differ only in that the first power output stage 32 are provided for driving the first coil 113 and the second power output stage for driving the second coil 115.
- the circuit arrangement and functioning of its components is equivalent.
- the first power output stage 32 is described below as an example.
- the first power output stage 32 (FIG. 2a) has a first transistor T1, the gate connection of which is electrically conductively connected to the control line L1, a second transistor T2, the gate connection of which is electrically conductively connected to the control line L2, and a third Transistor T3, the gate terminal of which is electrically connected to a control line L3.
- the first line Stungsendch 32 also includes diodes Dl, D3, D4, a free-wheeling diode D2, an electrical energy store designed as a capacitor C, and a resistor R, which is provided as a measuring resistor for the ammeter 34.
- the first power output stage can be controlled in five different operating states BZl, each of which is characterized by the respective switching state of the transistors T1, T2, T3. If there is a high voltage potential at the gate connections of the transistors T1, T2, T3, which are preferably designed as MOS transistors, the respective transistor T1,
- the five operating states BZl are plotted in FIG. 2e with the associated switching states of the transistors Tl, T2, T2.
- the five operating states BZl are an idle state RZ, normal energization NB, freewheeling FL, rapid current withdrawal SSR and rapid energization SB.
- the operating states BZl of the power output stage 32 are explained in more detail below 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 ALI 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 resistance 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), while the transistors Tl, T3 are not operated in a conductive state (OFF).
- a current flows from the connection ALI through the first coil 113 to the connection
- the freewheeling diode D2 becomes conductive and the current through the first coil 113 decreases 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 to the operating state BZl 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 ALI 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 significantly faster in the operating state of the rapid current reduction SSR than in the operating state BZl of the freewheel FL, since the negative supply voltage U B at the first coil 113 is reduced by the voltage drop U c at the capacitor C and the forward voltages of the freewheeling diode D2 and the diode D3 drops.
- 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).
- 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 drops at the first coil 113.
- 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 an embodiment in which a common capacitor C is assigned to both power output stages 32, 33.
- This embodiment has the advantage that only one capacitor is provided, as a result of which the power output stages are generally inexpensive, and the capacitor C can be charged in an operating state ZI of the first power output stage 32 of the fast current recovery SSR, and subsequently in an operating state BZ2 of the fast Energizing SB of the second power stage 34 can be discharged again. The reverse is also possible.
- the reference numerals of the Most 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.
- the current target position of the anchor plate 116 is read, which is specified by the higher-level control device.
- a step S2 it is checked whether the target position of the anchor plate 116 has changed to the open position 0 since the last call to the closed position S. If this is the case, then in a step S3 the first power output stage 32 is controlled in the operating state BZl rapid current reduction SSR.
- the first power output stage 32 changes to the operating state BZl 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 checks whether the target position of the anchor plate 116 has changed from the open position 0 to the closed position S since the last call of the first program. If this is the case, a first controller R1 is activated in a step S8.
- the controlled variable of the first regulator R1 is the current through the first coil 113.
- a catch value I_F is assigned to I_SP1 of the current through the first coil 113.
- 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 controller R1 is preferably designed as a two-point controller.
- the first controller Rl controls the first output stage 32 depending on the control difference RD either in the operating state BZl of the normal current NB or the freewheeling FL.
- the controller R1 remains activated until a predetermined condition is met, which is an indication of the anchor plate 116 hitting the first contact surface 115a.
- the predefined condition can be, for example, that the anchor plate has a predefined position. sition has reached or exceeded. This predetermined position is chosen so that it is very close to the closed position S.
- step S9 in which the first controller is reactivated, the setpoint I_SP1 of the current through the first coil 113 being an increased hold value I_HE.
- the first controller Rl controls the first power output stage 32 depending on the control difference RD either in the operating state BZl of the fast energization SB or in the operating state BZl of the freewheeling FL or, if the capacitor C is discharged, in the operating state BZl of the normal - Current NB.
- the first controller in step S9 controls the first power output stage 32 first into the operating state of the fast energization SB until the actual value I_AV1 of the current through the first coil is greater than the increased holding value I_HE, and / or in the operating state of the normal current supply, as soon as the capacitor C is discharged, namely until the actual value I_AV1 of the current through the first coil is greater than the increased holding value I_HE.
- the actual position of the armature plate 116 is very close or at the closed position S.
- the armature plate rests reliably on the first contact surface and neither bounces off nor falls into the rest position N before the closing position S is reached.
- the actual value I_AV1 of the current through the first coil 113 can be set very quickly to the increased holding value I_HE. This has the advantage that the first controller R1 in step S9 immediately before the anchor plate 116 strikes the first
- Contact surface 115a can be activated so that the speed of the anchor plate is no longer increased significantly so that the impact noise of the anchor plate on the first contact surface 115a is low. After a predetermined period of time, which is preferably determined by tests, 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 the hold value I_H and the controller controls the first power output stage 32 either in the state of the operating state BZl of the normal current NB depending on the control difference RD or the freewheeling FL until the target position of the anchor plate changes from the closed position S to the open position 0.
- the processing of the program is then ended in step S5.
- step S11 in which it is checked whether the target position of the armature 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 Rl 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 in the step
- step S11 If the condition of step S11 is not fulfilled, however, processing is continued in a step S13, in which the first power output stage 32 is controlled into an operating state BZl 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. Then in a step S14, the power output stage 32 is controlled in the operating state BZl 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 up cyclically, either at predetermined time intervals or after a predetermined change in the crankshaft angle. While the target position of the armature plate 116 is the open position 0, the first power output stage 32 is thus controlled once in step S3 into the operating state BZl of the rapid current withdrawal SSR and several times in the step S14 the operating state BZl of the rapid current withdrawal and thus the Capacitor C charged to the predetermined value within a predetermined period of time.
- the first coil 113 is controlled in the operating state of the freewheel in step S8 as soon as the energy required to reach the closed position S has been supplied to the armature plate.
- the coil first 113 is then freewheeling FL when the predetermined condition is met, which is an indication of the anchor plate 116 hitting the first contact surface 115a.
- FIG. 5 A flow chart of a second program for controlling the second coil 115 is shown in FIG. 5, which is processed in the control unit 31.
- the second program has the same structure as the first program ( Figure 4). Only the differences from the first program are described below.
- step S2 is checked whether the target position of the anchor plate 116 has changed since the last call of the first program from the open position 0 to the closed position S. If this is the case, then in a step S3 ' second power output stage 34 controlled in the operating state BZ2 rapid current withdrawal SSR. The second power output stage 34 changes to the operating state BZ2 of the idle state RZ as soon as the current through the second coil 115 becomes zero.
- step S7' checks whether the target position of the anchor plate 116 has changed from the closed position S to the open position 0 since the last call to the second program.
- a second controller R2 is activated, the controlled variable of which is the current through the second coil 115.
- a control difference RD ' is calculated from the difference between the setpoint I_SP2 and the actual value I_AV2 of the current through the second coil 115.
- the second controller R2 is preferably designed as a two-point controller.
- the second controller R2 controls the second output stage 33 depending on the control difference RD 'in accordance with how the first controller R1 controls the first output stage.
- the controller R2 remains activated in step S8 'until a predetermined condition is met, which is an indication of the anchor plate 116 hitting the second contact surface 115b.
- step S9 ' the actual position of the armature plate 116 is very close or at the open position 0.
- the armature plate on the second contact surface is reliable is present and neither rebounds nor falls into the rest position N before reaching the open position 0.
- step S7 ' If the condition of step S7 'is not fulfilled, the processing is continued in a step Sll', in which it is checked whether the target position of the anchor plate 116 is the open position. fenposition 0 or whether the capacitor C is charged to a predetermined value.
- step S11 ' If the condition of step S11 'is not met, the processing is continued in a step S13', in which the second power output stage 33 is controlled into an operating state BZl of the normal current supply NB, either for the predetermined period of time or until Actual value I_AV2 of the current through the second coil 115 has reached a predetermined value. Then, in a step S14 ', the second power output stage 33 is controlled into the operating state BZ2 of the rapid current reduction SSR.
