Definitions

  • the invention relates to a control circuit for Control of at least one solenoid valve for the Fuel metering in an internal combustion engine according to the Preamble of claim 1.
  • Such a control circuit is such. B. from the German Patent application 195 39 071 of Robert Bosch GmbH known. With this known control circuit, fast Solenoid valves e.g. B. for "common rail injection” or “Direct petrol injection” from internal combustion engines Booster and battery supply voltage FET switches controlled, which at the transition from the starting current to the holding current released energy in a capacitor is saved.
  • This circuit arrangement requires a variety of Components and complex driver circuits that it allow the valves to be controlled with large flows heading for.
  • the resulting ones are disadvantageous Dependencies of the switch-off edges for quick extinguishing of the solenoid valves from the battery voltage.
  • the core of the control circuit is a Recharge circuit that with the first and second connection the supply voltage to generate a pre-stabilized recharge voltage for the Storage capacitor from the battery supply voltage and is connected to the first switching means, the Reload circuit via third switching means between the first connection of the at least one solenoid valve and the recharge circuit are arranged, the solenoid valves from the energy stored in the storage capacitor in the Booster phase energized and the storage capacitor as well fourth switching means, which, controlled by the Control means, the reload circuit for reloading the Storage capacitor activated.
  • the battery voltage can cover a wide range, without affecting the switch-off time of the solenoid valves, the stabilized voltage above or below the Battery voltage may lie.
  • FIG. 1 graphically shows the course over time of the current intensity I (in amperes) through a solenoid valve during a control process of the same.
  • the HS booster FET 140 or 141 controls the current profile in the booster phase B from the energy stored in the storage capacitor 145.
  • the control circuit uses the first switching means, the U BATT -FET 115, to perform a starting current control AR at a relatively high starting current during a starting phase. This is followed by a first quick erasure SL to the holding current which is less than the starting current.
  • the control circuit according to the invention carries out a holding current regulation HR. This is followed by a second quick erase SL to the current level 0.
  • Figure 2 shows a block diagram of an inventive Control circuit as an example for two banks I and II.
  • Bank I contains, for example, three solenoid valves 100, 101 and 102, which are interconnected with their high-side ends and via the high-side booster FET 140 during the booster phase and via the high-side U during the pull-in phase and the holding phase BATT -FET 115 are energized.
  • the other ends of the solenoid valves 100, 101, 102 are each connected via diodes to the recharging circuit 1 and via one of the low-side FETs 120, 121, 122 and a measuring resistor R1 to a ground connection GND of the battery supply voltage U BATT .
  • the interconnected high-side ends of the solenoid valves 100, 101 and 102 are connected to the recharging circuit 1 via a diode and the high-side booster FET 140.
  • the proposed recharging circuit 1 has a choke coil 110 between a first battery supply voltage connection U BR and the second connection GND of the battery supply voltage, serially connected to it a diode 112, a storage capacitor 145 and a measuring resistor 111 and, parallel to the series connection of the diode 112 with the storage capacitor 145, a field effect transistor 113 on.
  • the function of the drive circuit shown in Figure 2 is as follows.
  • the solenoid valves 100, 101, 102 of bank I and 200, 201, 202 of bank II to be controlled are each selected via the corresponding low-side FET 120, 121, 122 or 220, 221, 222.
  • the high-side booster FET 140 from bank I or 141 from bank II controls the current profile.
  • the current profile is controlled by the high-side U BATT -FET 115 or 116.
  • the quick-erase phases SL are replaced by simultaneous Switching off the low-side field-effect transistors 120, 121, 122 or 220, 221, 222 and high-side field effect transistors 115 or 116 generated.
  • the high-side U BATT- FET 115 or 116 when the high-side U BATT- FET 115 or 116 is switched on, additional energy is fed back into the storage capacitor via the quick- erase diodes. To improve the energy balance, the high-side field-effect transistor 115 or 116 can also remain switched on after the starting phase.
  • the proposed recharging circuit 1 performs the Energy losses back to the storage capacitor 145.
  • the recharging circuit 1 either clocks continuously and / or is regulated accordingly to achieve a desired voltage.
  • the resistor 111 which is connected in series between the storage capacitor 145 and the second connection GND of the supply voltage U BATT , is used to measure the voltage at the storage capacitor 145.
  • the "hot" end of the measuring resistor 111 is connected to the driver circuit 11 or the control means.
  • the driver circuit 11 is connected via a line system a higher-level control unit (not shown) connected.
