Accordingly, the invention is implemented by a digital storage medium with a computer program that has program instructions that are suitable for executing the method according to the invention.
- Figure 1 shows a schematic block diagram of an embodiment of an inventive
- FIG. 2 shows a schematic circuit diagram for one of the electromagnetic valves with the current flow in four successive time ranges
- FIG. 3 shows a schematic time diagram of the current over one of the electromagnetic valves in the four time ranges
- FIG. 1 shows a device 10 for controlling at least two electromagnetic valves 11, 12.
- the electromagnetic valves 11, 12 are intended for use in an internal combustion engine, in particular a motor vehicle.
- the electromagnetic valves 11, 12 can be provided in connection with an electrohydraulic valve control of the intake and exhaust valves of the internal combustion engine.
- the electromagnetic valves 11, 12 control a hydraulic system with which the intake and exhaust valves of the internal combustion engine can be opened and closed.
- the device 10 described below can not only be used for the two valves 11, 12 shown, but that the device 10 can also be used for any number of valves by appropriate extensions. It is thus possible for a total of 32 solenoid valves for controlling the intake and exhaust valves of the internal combustion engine to be present in an internal combustion engine with four cylinders.
- DC-DC converters 13, 14 To supply the valves 11, 12 with energy, two DC-DC converters 13, 14 are provided, which together form a converter 17. Both DC-DC converters 13, 14 and thus the converter 17 contain controls and / or regulations for maintaining the generated ones
- the DC-DC converter 13 is suitable for generating a booster current on an electrical line 15. Accordingly, the DC-DC converter 14 is suitable for generating a holding current on an electrical line 16. The booster current is larger than the holding current.
- an output stage 20 is provided with which the current flow is controlled via the valves 11, 12.
- This control is carried out by a control device 19.
- the function of the output stage 20, its control and the current flow thus generated via the valve 11 is explained in more detail below with reference to FIG. 2. The explanation there also applies in a corresponding manner to the current flow via the valve 12 and to the current flow via any further valve.
- the line 16 is connected to one of the two connections of the electromagnetic valve 11 via a diode D1 switched in the direction of flow.
- connection of the electromagnetic valve 11 is connected to the line 15 via a diode D2, which is also switched in the direction of flow.
- the cathodes of the two diodes D1, D2 are connected to one another via a switch S1.
- the anode of the diode D2 is connected to ground via a switch S2.
- FIG 3 shows the current I NV over the electromagnetic valve 11 over time.
- the four time ranges a, b, c, d are shown in FIG result from the four adjustable switch positions of the two switches S1, S2.
- the two switches S1, S2 are closed. This results in a current flow a, as shown in FIG. 2 and correspondingly labeled “a X ”.
- the booster current generated by the DC-DC converter 13 flows via the valve 11.
- This current I M v increases according to FIG. 3 up to a final value and is provided in each case to adjust the valve 11 to a predetermined end position.
- switch S1 is open and switch S2 is closed. This results in a current flow, as shown in FIG. 2 and marked with “c”.
- the holding current generated by the voltage converter 14 is supplied to the valve 11. The holding current is chosen such that the end position that valve 11 has reached due to the booster current is not changed.
- 4a shows the booster current I B generated by the DC / DC converter 13 for the connected valves 11, 12 over the time t.
- the result of the high booster current 22 is that the DC voltage converter 13 provided for the booster currents is exposed to very high loads. The following is provided for better processing of these loads:
- the control unit 19 is connected to the converter 17, in particular to the direct voltage converter 13 responsible for the booster current, via a line 18.
- the control unit 19 determines when a high load due to overlapping booster currents will occur. This can be derived from the control device 19 from the controls provided for the switches S1, S2 of the output stage 20.
- control unit 19 Before a high load occurs, the control unit 19 indicates the impending high load to the converter 17, in particular the DC voltage converter 13. This happens with the help of a signal S, which is transmitted from the control unit 19 to the converter 17 via the line 18.
- the signal S is plotted over time t. It can be seen that the signal S is present during a time period T which extends from a time T1 to a time T2. This is identified in FIG. 4b by reference number 23.
- the time period T corresponds approximately to that
- the output voltage U B of the DC-DC converter 13 is plotted over time. As already mentioned, this output voltage Ü B is controlled and / or regulated to a predetermined setpoint.
- the setpoint is identified in FIG. 4c with the reference symbol U BS oi ⁇ .
- the control and / or regulation of the DC / DC converter 13 is designed, for example, such that the output voltage U B of the DC / DC converter 13 moves within a tolerance band of +/- 10% around the setpoint U B s.
- the setpoint value U B s of the output voltage U B of the DC voltage converter 13 is increased during the time period T. This is shown in dashed lines in FIG. 4c and is identified by reference numeral 24.
- the DC-DC converter 13 thus supplies an increased output voltage U B according to reference number 25. This ensures that the DC-DC converter 13 can better process the high load associated with the increase in the booster current I B.
- the increased setpoint U Bs oi ⁇ and the resulting increased output voltage U B ensure that the drop in this output voltage U B is less than without the aforementioned increase due to the high booster current I B.
- FIG. 4c On the basis of the curve profiles which are identified by the reference symbols 26, 27.
- the curve shape that results from the increase in the setpoint U BS oi ⁇ is shown in dashed lines and identified by the reference number 26, while the curve profile that would result without the increase in the setpoint value Ußsoii described above is identified by the reference number 27.
- the control and / or regulation contained in the converter 17 can take preventive measures based on the signal S, in particular there due to the increase in the signal S at the beginning of the time period T, before the occurrence of a control deviation, so that Counteract control deviation that results from the high booster current.
- the control and / or regulation can preventively increase the output power of the DC / DC converter 13.
- control unit 19 can remove the remaining one
- Control and / or regulate DC voltage converter 13 such that it takes over the function of the DC voltage converter 14 and additionally generates the holding current.
- the output voltage of the DC-DC converter 13 can be pulsed in order to generate a corresponding holding current.
- control unit 19 can control the control unit 19 in the opposite case.
- the control device 19 can increase the target value of the output voltage of the DC-DC converter 14.
- it can make sense for the control unit 19 to trigger the switches S1, S2 earlier in order to generate the booster current, in order to compensate for possible deteriorations in the tightening dynamics of the valves 11, 12.
