- Component of the fuel injection system or the internal combustion engine depends. To characterize the efficiency of the electromagnetic
- Actuation device is proceeded as follows: In an adaptation method, an energy supplied to the electromagnetic actuator is successively changed from a starting value to such a final value, in which a closing or opening of the quantity control valve is no longer or only just detected. The final value or a quantity based thereon is used to characterize the efficiency of the electromagnetic actuator. For a particularly accurate adaptation of the control of the quantity control valve to the specimen properties, an exact characterization of the specimen properties is required. Often two or more parameters are necessary for this characterization. However, with only one measurement as known in the art, two characteristics can not be determined independently.
- the invention relates to a method for controlling a quantity control valve, wherein at least two parameters characterize the quantity control valve, wherein a control signal supplied to the quantity control valve is defined by at least two parameters.
- the inventive method allows in particular the independent determination of two the behavior of the
- Quantity control valve characterizing parameters.
- Adjust quantity control valve in a suitable manner to the specimen properties of the quantity control valve.
- Quantity control valve wherein a the quantity control valve supplied
- Drive signal is defined by at least two parameters, which is characterized
- Adaptation at least one parameter is determined, or that based on the result of a first adaptation and a first parameter, a second parameter is determined, allows the determination of the specimen properties.
- the properties of the quantity control valve vary from item to item
- Quantity control valve Characterized in that in a second adaptation, at least a third parameter is maintained at a second constant value, and at least a fourth parameter is changed from a second start value to such a final value, in which closing or opening of the quantity control valve just no longer or straight is first determined, it is possible in conjunction with the final value of the first adaptation, the characterizing relationship between
- the result is an embodiment in which the same parameter is adapted in both adaptations.
- This embodiment is particularly easy to implement on a control unit.
- the two results are independent, which allows the characteristic relationship between
- Parameters are adapted. This embodiment in conjunction with that at least the first constant value and the second start value or the first start value and the second constant value are unequal allows the characteristic relationship between the drive signal and the closing / opening behavior of the
- Quantity control valve to describe by two parameters.
- Embodiment allows the particularly robust determination of the two characteristics describing the characteristic relationship. It is particularly easy to carry out the method according to the invention for pulse-width-modulated drive signals if one of the parameters belongs to the group given by duty cycle during a hold phase or an equivalent size and duration of a pull-in pulse or an equivalent variable.
- Carrying out the method according to the invention for electromagnetically controlled quantity control valves is particularly simple if at least one of the parameters belongs to the group given by the efficiency of the quantity control valve or of an equivalent size and ohmic total resistance deviation or of an equivalent size.
- the parameter is determined by a measurement or by an estimate or read from the control unit, it can be in
- the characteristic relationship between the drive signal and closing / opening behavior of the quantity control valve are described by two parameters. This is particularly efficient because only one adaptation is necessary to determine the two parameters. If an ohmic resistance of a supply line is used as the parameter, this allows, in particular, the particularly simple determination of the ohmic total resistance deviation.
- the preceding methods can be used in such a way that, starting from the characterizing variables, the parameters of the triggering signal of the quantity control valve are changed in such a way that an emission of audible sound produced when the solenoid valve is closed is at least partially reduced.
- the implementation of the preceding methods is advantageously carried out with a computer program programmed for use in a method according to one of the preceding descriptions.
- the inventive method thus allows a particularly good adaptation of the control of the quantity control valve to the specimen properties.
- One The advantage is the reduction of audible sound when closing the
- Quantity control valve during operation of the internal combustion engine arises.
- a further advantage is that the holding current level can be adapted to the exemplary behavior of the valve and the total ohmic resistance effective for the drive signal. For example, the holding current level can be minimized, dissipating less power dissipation and unnecessarily high
- Another advantage is in controls of energized open electromagnetically controllable quantity control valves, in which the acoustic behavior during opening by a force applied by the electromagnetic control brake pulse, which slows down the movement of the armature, is improved.
- the braking pulse can be adapted in a particularly suitable manner to the specimen properties of the quantity control valve, which improves the robustness of the desired behavior in borderline pattern cases.

- FIG. 6 analogous to FIG. 5, with a different constellation of the varied parameters held at a constant value, in the event that the same parameter is not varied in both adaptations.
- a fuel injection system bears the overall reference numeral 10. It comprises an electric fuel pump 12 with which fuel is conveyed from a fuel tank 14 to a high-pressure pump 16.
- High pressure pump 16 compresses the fuel to a very high pressure and promotes it further into a fuel rail 18.
- injectors 20 To this several injectors 20 are connected, which inject the fuel in them associated combustion chambers.
- the pressure in the fuel rail 18 is detected by a pressure sensor 22.
- the high-pressure pump 16 is, for example, a
- Camshaft in a reciprocating motion can be offset.
- the delivery piston 24 defines a delivery chamber 28, which via a
- Quantity control valve 30 can be connected to the outlet of the electric fuel pump 12. Via an outlet valve 32, the delivery chamber 28 can also be connected to the fuel rail 18.
- the quantity control valve 30 comprises an electromagnetic
- Actuator 34 which operates in the energized state against the force of a spring 36.
- the quantity control valve 30 When de-energized, the quantity control valve 30 is open, in the energized state it has the function of a normal inlet valve.
- the electromagnetic actuator 34 may be designed in particular as a magnetic coil. This is referred to below as "coil”.
- the electromagnetic actuator 34 is driven by a control and regulating device 54, which is connected to it via a current-carrying line 56.
- the efficiency of the mass control valve 30 is defined as the ratio of the (quasi-static) attraction force on the armature that is being required for tightening to the actual quasistatic current in the coil at that moment. If the factor is normalized so that nominal valves have an efficiency of 1, for example, efficient patterns (fast tightening) have efficiency> 1, inefficient patterns (slow tightening) efficiency ⁇ 1. Efficiency is determined, for example, by tolerances in the design of the magnetic circuit as well as the other dynamic parameters. Another residual air gap, for example, leads u.a. to a decrease in efficiency, since at constant current less magnetic flux is built, resulting in less attractive force. A high spring force also leads to a decrease in the tightening force, and thus to an efficiency ⁇ 1.
- the ohmic total resistance consists of several serial
- Partial resistors together (e.g., from: coil of the quantity control valve, lines, contact resistance, power amplifier). Each of these resistors, however, is subject to uncertainties of resistance, which with a controlled pilot control of the quantity control valve 30 certain
- Deviations occur. Examples of such uncertainties result, for example, from errors in the temperature model of the coil, or from
- Drive voltage U is clocked in the embodiment in terms of pulse width modulation.
- the middle diagram 2b of Figure 2 shows the corresponding coil current I.
- the corresponding stroke H of the quantity control valve 30 is shown.
- the voltage signal U and the coil current I resulting therefrom initially have a so-called "starting pulse" 56.
- the coil is driven with a constant voltage
- the pull-in pulse 56 is followed by a holding phase 58, in which the coil is driven with a pulsed voltage 64.
- the effective drive voltage U is determined by the duty cycle
- the resulting coil current 60 shows a timing corresponding to the voltage signal and, depending on the effective drive voltage, an increase, a largely constant behavior (as illustrated in the exemplary embodiment in FIG.
- Movement sets and closes at a time t 2 and goes to attack, resulting in a strike noise.
- Quantity control valve 30 is advantageously defined by at least two parameters.
- these are, for example, the duty cycle during the hold phase 58 and the duration of the tightening pulse 56.
- a pulse-width-modulated control is assumed in the following, their signal through the two parameters
- Duty cycle during the holding phase and duration of the tightening pulse is defined.
- a parameter of the control of the quantity control valve 30 for example, the duration of the tightening pulse
- the other parameters eg the duty cycle during the holding phase
- the efficiency and the ohmic total resistance deviation represents.
- the characterizing parameters influence the properties of the quantity control valve in the same way. These are, for example, first the case of low efficiency and positive ohmic total resistance deviation and secondly the case of high efficiency and negative ohmic
- the three cases are, in particular, low efficiency and negative ohmic total resistance deviation, secondly high efficiency and positive ohmic total resistance deviation, and thirdly nominal efficiency and vanishing ohmic
- the method according to the invention allows the independent determination of the two characterizing parameters, that is, for example, of efficiency and ohmic total resistance deviation.
- the method according to the invention is based on the knowledge that a single measured quantity (for example the result of an adaptation) can not be used for the simultaneous reliable estimation of two independent unknown parameters (in the exemplary embodiment the efficiency and resistive total resistance deviation). If, on the other hand, according to the invention, a second adaptation is carried out, which takes place, for example, with a changed basic parameterization, then two parameters (in the exemplary embodiment the efficiency and ohmic total resistance deviation) can be determined from the result of the first adaptation and the result of the second adaptation. As part of the
- Embodiment is hereinafter assumed that the two characteristic of the behavior of the quantity control valve 30 characteristics are given by the efficiency and the ohmic total resistance deviation.
- other variables can be used as parameters, for example one for efficiency or ohmic
- FIG. 3 shows the sequence of the method according to the invention.
- a variation of a parameter e.g. the duration of the tightening pulse 56
- the closing behavior of the quantity control valve 30 varies.
- the result 94 of this first adaptation 90 is the value of the varied one
- a parameter e.g. the duration of the tightening pulse 56
- the closing behavior of the quantity control valve 30 varies.
- the result 98 of this second adaptation is the value of the varied parameter at which the quantity control valve 30 is no longer or just now closing.
- This first parameter 102 and this possibly second parameter 104 are used in the control and regulating device 54 in order to generate, for example with the aid of a characteristic map, an improved control of the quantity control valve 30, in particular with respect to the acoustic behavior.
- the duration of the tightening pulse 56 is varied successively while the duty cycle is kept constant during the holding phase 58, until it is determined that the quantity control valve 30 is no longer or just closing. This is done, for example, by evaluating the measuring signal of the pressure sensor 22.
- the result 94 in this embodiment is the value of the duration of the tightening pulse at which the quantity control valve 30 is no longer or just now closing.
- the duty cycle during the holding phase 58 while simultaneously keeping the duration of the tightening pulse 30 is varied successively until it is determined that the quantity control valve just no longer or just closes.
- the result 98 is in this
- Flow control valve 30 just stops or is just closing.
- FIG. 10 An alternative embodiment is shown in FIG.
- a variation of a parameter e.g. the duration of the tightening pulse 56, the closing behavior of the quantity control valve 30 varies.
- the result 94 of this first adaptation 90 is the value of the varied one
- a first parameter 102 is provided.
- a second parameter 104 is determined. This first parameter 102 and this second parameter 104 are used in the control and regulating device 54 in order to generate, for example with the aid of a characteristic map, an improved control of the quantity control valve 30, in particular with regard to the acoustic behavior.
- the default 100 can be given, for example, by measuring the ohmic total resistance deviation. This is done according to the invention particularly advantageous by the evaluation of a current value of
- the effective current according to the invention is particularly advantageous over a plurality of phases of the pulse width modulated
- pulse width modulated drive signal allows the most simple
- the efficiency as a second parameter is then determined on the basis of the measurement of the total ohmic resistance deviation and of the result of FIG.
- FIG. 5 describes the relationship of the first adaptation 90 and the second adaptation 92 to one another.
- a first parameter 110 - e.g. the duty cycle during the hold phase 58 - held at a first constant value 112
- a second parameter 114 - e.g. the duration of the tightening pulse 56- changed from a first starting value 116 to such a final value, in which closing or opening the
- Quantity control valve 30 is not or only just determined.
- a third parameter 118 - eg the duty cycle during the hold phase 58 - is held at a second constant value 120 and a fourth parameter 122 - eg the duration of the pull-in pulse 56 - is changed from a second start value 124 to such a final value. in which a closing or opening of the quantity control valve 30 is no longer or just just determined.
- the first parameter 110 and the third parameter 118 both the duty cycle during the hold phase 58 and the second parameter 114 and the fourth
- Parameter 122 is both the duration of the pull-in pulse 56.
- the first parameter 110 thus corresponds to the third parameter 118 and the second parameter 114 to the fourth parameter 122.
- FIG. 5 Analogous to FIG. 5, another possible embodiment is shown in FIG.
- the duty cycle during the hold phase 58 is held at a second constant value 120 and the duration of the pull-in pulse 56 is changed
- the duration of the pull-in pulse 56 is maintained at a first constant value 110 and the duty cycle during the hold phase changed.
- the first parameter 110 and the fourth parameter 122 correspond to both e.g. both the duration of the pull-in pulse 56
- the second parameter 114 and the third parameter 118 both the duty cycle during the hold phase 58.
- the first parameter 110 thus corresponds to the fourth parameter 122 and the second parameter 114 to the third parameter 118th
- the start parameterization be different from the constant value and the starting value. In the constellation shown in Figure 5, this means that either the first constant value 112 is different from the second constant value 120, or the first start value 116 is different from the second start value 124, or both.
- Characteristics is advantageously repeated at long intervals. The reason for this is the fact that over time a slow change in the
- Characteristics e.g. efficiency, occurs. This is caused for example by wear. Since this change is slow, it is advantageous to store the determined parameters, for example in the control unit.
- maps are used in the method described, it is advantageous to adapt these maps to the current battery voltage, since the currents in the control of the quantity control valve and possibly the result of an adaptation (in particular, if the adapted parameter is given by the duty cycle) of the Battery voltage can depend.
