Definitions
- the invention relates to a method for operating a fuel injection system, in particular a motor vehicle according to the preamble of claim 1.
- the invention also relates to a corresponding computer program, a corresponding electrical memory, a corresponding control unit and a corresponding fuel injection system, in particular for a motor vehicle.
- Fuel storage provided, the fuel is supplied via a metering unit and a high-pressure pump. Furthermore, it is known to influence the actual pressure in the fuel storage, inter alia with the aid of an I-controller.
- the object of the invention is to provide a method for operating a fuel injection system, with the exact injection of the correct injection quantity is ensured even with a change of the operating point of the fuel injection system.
- a precontrol value is generated by a pilot control map with which production-related deviations from components of the fuel injection system are compensated.
- the scatter of different fuel injection systems is thus not compensated by the I controller, but by the additional pilot control map according to the invention.
- Fuel injection system gradually determined and entered in the pilot control map. This ultimately represents a learning process of the pilot control map.
- Fuel injection systems are automatically taken into account. A separate recording of these differences, for example, before the commissioning of the
- Fuel injection system is not required.
- the inventive method is thus easy and inexpensive to apply.
- the output value of the I-controller is in an operating point of the fuel injection system in the pilot control map entered. This represents the learning process of the pilot control map.
- the output value of the I-controller is distributed to a plurality of nodes of the pilot control map.
- the associated pilot value is read from the pilot control map during operation of the fuel injection system for the current operating point thereof. This means that the pre-tax value required to compensate for production-related deviations is immediately available. The production-related deviations must therefore no longer be compensated with the help of the I-controller.
- FIG. 1 shows a schematic block diagram of an exemplary embodiment of a method according to the invention for operating a fuel injection system
- FIG. 2 shows a detail of a pilot control map which is used in the method of FIG.
- FIG. 1 is a fuel injection system 10 a Internal combustion engine shown.
- a fuel injection system 10 a Internal combustion engine shown.
- Fuel injection system 10 is in particular a high-pressure fuel injection system and the internal combustion engine may in particular be a diesel internal combustion engine for a motor vehicle.
- the fuel injection system 10 has a pump 11, in particular a high-pressure pump, to which the fuel is supplied via a metering unit 12.
- the pump 11 is connected on the output side to a fuel reservoir 13, in which the fuel is stored under pressure.
- the fuel accumulator 13 is connected to injection valves, via which the fuel is injected into combustion chambers of the internal combustion engine.
- the fuel accumulator 13 is associated with a pressure sensor 14, with which the pressure in the fuel storage 13 is measured.
- the fuel injection system 10 is controlled and / or regulated by a control unit, not shown.
- the control unit has a computer with an electrical storage medium, in particular with a flash memory.
- a computer program is stored, which is executable on the computer. This computer program is adapted to affect the fuel injection system 10 and thus perform the desired control and / or regulation.
- FIG. 1 also shows a method 20 for operating this fuel injection system 10 in the form of a block diagram.
- This method 20 is executed by the controller.
- parts of the method 20 may also be realized with the aid of analog electronic modules.
- a signal corresponding to the actual pressure ID in the fuel storage 13 is generated and given to a comparator 21.
- the actual pressure ID is compared with a target pressure SD.
- the differential pressure DD is passed on to three controllers, namely a P controller 22 (proportional controller), a D controller 23 (differential controller) and an I controller 24 (integral controller).
- the outputs of these three regulators are added by an adder 25 to a desired fuel flow control value DS. This desired fuel flow is then supplied from the metering unit 12 of the pump 11 and thus the fuel storage 13.
- a pre-control signal Vl is provided, which is added via an adder 26 to the control value DS.
- a pilot control map 27 is provided, the output-side pilot signal V2 of which via an adder 28 to the control value DS for the
- Fuel flow is added. As input signals to the pilot control map 27, the current injection quantity q and the current speed n are supplied.
- the desired fuel flow control value DS is supplied to a characteristic curve 29 representing the metering unit 12. With the aid of this characteristic curve 29, the control value SS for a current with which the metering unit 12 must be actuated in order to generate the desired fuel flow rate is determined from the control value DS.
- This control value SS represents a desired value for a downstream current controller 30. From this current controller 30, the metering unit 12 is then assigned the control value SS corresponding current applied. The current actually flowing through the metering unit 12 is measured by a sensor 31 and given as actual value IW to a comparator 32. There, the actual value IW is subtracted from the control value SS. The difference then acts on the current regulator 30.
- the actual pressure ID present in the fuel reservoir 13 is regulated to the desired pressure SD.
- the desired pressure SD include the three
- the metering unit 12 is then influenced.
- the metering unit 12 acting on the current is controlled by the current controller 30.
- the metering units of various fuel injection systems are subject to production-related scattering.
- the metering unit of a first fuel injection system for example, a different efficiency and thus a different characteristic than the metering unit of a second fuel injection system.
- these production-related deviations of the components of the fuel injection system 10 are taken into account by the pilot control map 27 and the pilot signal V2 resulting therefrom.
- an adaptive feedforward control is realized in particular with the aid of the pilot control map 27.
- pilot control map 27 After the production of the fuel injection system 10, no values are contained in the pilot control map 27. From the pilot control map 27 so that only the value zero can be read. The pilot control map 27 at this time has no influence on the method 20 for operating the fuel injection system 10.
- the pilot control map 27 is gradually filled with values during operation of the fuel injection system 10. For this purpose, it is determined whether the fuel injection system 10 is currently in a steady-state operating point. If this is the case, then for this operating point the associated output value of the I-controller 24 is further processed in addition to the already explained method 20 as explained below. This operating point-dependent output value of the I-controller 24 is indicated in FIG. 1 by the reference symbol Ix.
- FIG. 2 shows a section from the pilot control map 27 of FIG. On the two axes of this pilot control map 27, the injection quantity q is plotted against the rotational speed n.
- the first interpolation point MlI belongs to an injection quantity q1 at a rotational speed n1
- the second interpolation point M12 to an injection quantity q2 at the rotational speed n1
- the third interpolation point M21 to the injection quantity q1 at the rotational speed n2
- the fourth interpolation point M22 to the injection quantity q2 at the Speed n2.
- the current steady-state operating point Mx of the fuel injection system 10 is shown. This operating point belongs to the current injection quantity qx and the current speed nx.
- the instantaneous operating point Mx is arranged within the rectangle spanned by the four support points MlI, M12, M21, M22 and thus adjacent to all four support points MI1, M12, M21, M22.
- the current operating point Mx of the fuel injection system 10 thus does not coincide with any of the interpolation points MlI, M12, M21, M22 of the pilot control map 27.
- the output value Ix of the I-controller 24 belonging to this operating point Mx is therefore sent to the four interpolation points MlI, M12, M21,
- M22, new M22, old + Ix * (nl - nx) 2 * (ql - qx) 2 .
- the closest support point is always more strongly influenced, while the other three support points are less affected. If the instantaneous operating point Mx falls into one of the interpolation points MlI, M12, M21, M22, then the associated output value Ix of the I-controller 24 is taken into account only at this interpolation point, but not at the other three interpolation points.
- the values stored in the pilot control map 27 are read out and used as pre-control values V2 in the method 20 of FIG.
- the support points When reading from the pilot control map 27, in turn, the support points, but taken into account in the reverse procedure.
- the support points arranged adjacent to the instantaneous operating point are determined.
- the values stored in these four interpolation points are read from the pilot control map 27.
- These four values are linked to the precontrol value V2 via a predetermined function, preferably via a linear interpolation. In this interpolation, the arrangement of the current operating point with respect to the four adjacent nodes is taken into account.
- the I-controller 24 indicates a particular one
- the I-controller 24 supplies, inter alia, an output value Ix exactly when one or more components of the fuel injection system 10 have production-related deviations. If, for example, the metering unit 12 has an actual characteristic due to production-related variations, which deviates from the characteristic curve 29 of the metering unit 12 provided, this deviation from the I-controller 24 is compensated by a corresponding output value Ix. By the explained assumption of such output values in the pilot control map 27 then gradually all deviations of the characteristic of the metering unit 12 are no longer compensated by the I-controller 24, but by the pilot value V2 of the pilot control map 27th
- Output values always approximates over a time constant.
- the I-controller 24 no longer has to supply an output signal, at least with regard to production-related deviations of the components of the fuel injection system 10.
