  • the current evaluation 135 acts on a current controller 140 with an actual value II for the current.
  • the current controller applies a signal Vtc to the output stage 130 and a filter 145.

It can also be provided that the measuring means 120 is arranged between the consumer 100 and the switching means 110. Is the measuring means 120 between the electromagnetic consumer 100 and the switching means 110 or between the electromagnetic consumer 100 and the positive pole Ubat of the supply voltage, the current values can also be detected and evaluated after opening the switching means 110.
  • the diode 105 serves as a freewheeling circuit and represents the simplest implementation of such a freewheeling circuit. It can optionally be replaced by other switching elements such as, for example, a plurality of diodes connected in series or by a series connection of transistor and diode. The same applies to the Z diode 108, which serves as an extinguishing device and can, if necessary, be replaced or supplemented by other suitable components.
  • the switching means 110 is preferably a transistor, in particular a field effect transistor.

  • the control unit 155 evaluates the signals from various sensors 160.
  • the sensors 160 record, for example, the rotational speed, the accelerator pedal position, various temperature and pressure values, and, in particular in the case of spark-ignited internal combustion engines, the throttle valve position. Based on these sensor signals and operating parameters, the control unit 155 calculates various signals for controlling various actuators 165.
  • control unit 155 specifies a signal DRVO that specifies the activation duration of the switching means 110.
  • Switching means 110 closes on the positive edge of signal DRVO and switching means 110 opens on the negative edge.

  • the current is preferably regulated to a higher value and in a second phase to a lower value.
  • the current evaluation 135 determines the actual current flowing through the consumer 100 based on the voltage drop across the resistor 120.
  • the current controller 140 compares the actual current II with the target current IS. Based on this comparison, it generates a control signal Vtc to act on the output stage 130, which then controls the switching means 110 accordingly.
  • the output signal of the current regulator 140 is further processed by the filter 145.
  • This filter generates a voltage value that is proportional to the pulse length of the output signal Vtc of the current regulator 140.
  • the switching time can be determined by evaluating the pulse length.
  • the time window 150 permits this evaluation only within a specific time range after the solenoid valve has been activated.
  • FIG. 2 in which various signals are plotted over time.
  • the DRVO signal is shown in the first line. This signal is transmitted from the control unit 155 to the output stage 130.
  • the signal CHIL which is also transmitted from the control unit 155 to the output stage 130, is plotted in the second line. While this signal is present, the second setpoint of the current is regulated.
  • the third line shows the current I flowing through the solenoid valve.
  • the stroke H of the solenoid valve needle is shown in the fourth line.
  • the fifth line shows the signal Vtc which corresponds to the output signal of the current regulator 140. This signal also corresponds to the switching state of the switching means 110. The switch is open when the signal value is low, and the switch is closed when the signal value is high.
  • the filtered pulse length of this signal is plotted on the next line. This signal is only present internally in filter 145.
  • the seventh line shows the signal VCLP, which assumes an increased value when the frequency exceeds a certain threshold value.
  • the next signal CLPV defines with its increased signal value the time window within which the switching time is usually. This signal is transmitted from the control unit to the time window 150.
  • the signal CLP the positive edge of which defines the switching instant, is plotted in the last line.
  • the output stage 130 controls the switching means 110 in such a way that it closes or there is a non-zero setpoint for the current I. This means that the output signal Vtc of the current regulator 140 takes on an increased value.
  • the current regulator 140 regulates the current flowing through the solenoid valve to a desired value IS1 specified by the control unit.
  • This current regulator is preferably implemented as a two-point regulator.
  • the two-point controller opens the switching means 110 when an upper current threshold is exceeded.
  • the lower current threshold is fluid and is reached by deactivating the switching means for a certain time TP. This means that when the current value is exceeded, the switch opens and after the predetermined time TP the switch closes again.
  • the current I through the solenoid valve fluctuates between a predetermined upper threshold and a lower value.
  • the solenoid valve needle Shortly before the end of the Tlreg period, the solenoid valve needle begins to move towards its new end position.
  • the switching state of the switching means 110 or the output signal of the current regulator changes between its upper and lower signal value.
  • the switching means is closed for a relatively long time.
  • the switch-off time TP is set so that a desired hysteresis of the two-point controller is achieved.
  • the setpoint which corresponds to the upper current threshold S1
  • the setpoint S1 in the first phase is called the starting current and the setpoint S2 in the second phase is called the holding current.
  • the setpoint value for the current is lowered after the solenoid valve needle has started to move.
  • This point in time is estimated by the control unit 155 depending on various operating parameters. After this point in time has been reached, the control unit 155 outputs a signal CHIL with a positive edge. From the positive edge of the signal CHIL, a constant or linearly decreasing switch-off time TP is specified, so that a desired hysteresis or sufficient accuracy of the switching time is achieved. If the switch-off time TP is reduced linearly or non-linearly in the direction of the expected closing time, the accuracy or the sensitivity of the detection can be improved.
  • the advantage of a variable switch-off time is a reduced power loss of the switching element 110, since the highest switching frequency only occurs in the vicinity of the closing time.
  • the pulse length of the signal Vtc changes suddenly. If one now considers the pulse length of the signal Vtc, one can see a sudden change or increase in the pulse length at the time of switching. As soon as the filtered pulse length exceeds the threshold value S, the signal VCLP has a positive edge. In order to prevent error detections, the VCLP signal only recognizes as permissible between the positive and the negative edge of the CLPV signal.
  • a positive edge of the signal CLP is transmitted to the control unit 155.
  • This positive edge characterizes the switching time of the solenoid valve. Due to signal delays, the edge is around the delay time Td after the actual switching time. This delay time Td is a function of the filter and the switching frequency at the time of closing and is taken into account by the control unit 155.
  • the period duration change is evaluated by a two-point controller with an upper and lower threshold if the current in the solenoid valve 100 can be measured directly. It is essential that a variable characterizing the switching state of the switching means 110 is evaluated. changes the control signal of the switching means or the output variable of the current controller 140, the time of the change corresponds to the switching time of the electromagnetic consumer.
  • the program begins with step 100.
  • the current is regulated by the current controller 140 to a first setpoint IS1.
  • step 320 the current controller 140 regulates the current on the. second setpoint IS2.
  • the subsequent query 330 checks whether the CLPV signal is present. If this is not the case, the program continues with step 320. If the signal CLPV is present, step 340 follows. Here, a constant value is specified for TP. Then, at step 350, the pulse length is determined from the signal Vtc and filtered. The query 360 checks whether the filtered signal Vtc is greater than a threshold S. If this is not the case, step 350 takes place again. Otherwise, if the pulse length is greater than a threshold S, the signal CLP is output.
