Definitions

  • the invention relates to a method for operating an electromagnetic actuator, in particular a fuel injection valve of an internal combustion engine of a motor vehicle, in which the electromagnetic actuator is activated during an activation process in order to influence an operating state of the actuator.
  • the invention also relates to a control device for carrying out such an operating method.
  • a method of the type mentioned is already from the DE 101 38 483 A1 known.
  • the known method provides for applying a current pulse to the electromagnetic actuator before it is activated, and for correcting the control based on a variable that characterizes the duration of the current pulse. This ensures that a control duration for several control processes with different supply voltages is constant.
  • the disadvantage of the known method is the requirement to have to provide a separate current pulse before the actual control of the electromagnetic actuator. This results in particular restrictions with regard to the minimum time intervals between successive actuation processes. In addition, the current pulses that are not themselves part of the control increase the electrical energy requirement of a corresponding circuit.
  • the DE 101 34 332 A1 discloses a device and a method for controlling a consumer, in particular for metering fuel in an internal combustion engine. At least a first control and a second control of the consumer take place. The beginning of the second activation is at a minimum distance from the end of the first activation. In certain states, a variable is recorded that characterizes the flow of current in the consumer after the consumer has been activated. The minimum distance is determined on the basis of this size.
  • the electromagnetic actuator be controlled as a function of a magnetization parameter that characterizes the magnetization current.
  • the magnetization parameter can be determined, for example, as a function of a time profile of a coil current flowing through a magnet coil of the electromagnetic actuator.
  • This variant of the invention is distinguished by its low complexity and allows the magnetization parameter considered according to the invention to be determined by a simple time measurement.
  • both the activation duration for the current activation process and / or an activation start can be specified as a function of the state of the magnetic circuit and / or the magnetization parameter.
  • Another very advantageous embodiment of the method according to the invention provides that a coil voltage applied to the magnet coil is determined at a defined point in time before the start of the control process, and that the magnetization parameter is formed as a function of this determined voltage value.
  • a formation of the magnetization parameter as a function of several of the aforementioned variables is also conceivable.
  • the state of the magnetic circuit is determined based on a model as a function of at least one control variable for the electromagnetic actuator.
  • a state of the magnetic circuit of the electromagnetic actuator can be determined particularly precisely as a function of at least one control variable for the electromagnetic actuator.
  • the state of the magnetic circuit of the electromagnetic actuator can be determined not only at the beginning of a respective control process, but also at further operating times of the electromagnetic actuator.
  • the state of the magnetic circuit can be particularly advantageous as a function of one or several previous control processes can be determined, resulting in increased precision with regard to the information characterizing the state of the magnetic circuit.
  • a control device according to patent claim 7 is specified as a further solution to the object of the present invention.
  • the fuel injector 100 has an electromagnetic actuator 10, which drives at least one component of the fuel injection valve 100, not shown here, for example a valve needle, in order to effect fuel injections.
  • the electromagnetic actuator 10 is controlled by a control device 20 assigned to it.
  • the control device 20 has a computing unit such as a microcontroller or a digital signal processor (DSP), which are suitable for executing a computer program representing the method according to the invention.
  • DSP digital signal processor
  • Figure 2 shows a simplified equivalent circuit diagram of a magnetic circuit 11 of a typical electromagnetic actuator 10 ( Figure 1 ).
  • the equivalent circuit has a resistor R_c, which represents the ohmic resistance of a primary coil of the electromagnetic actuator 10.
  • a main inductance L_h which represents an inductance of the magnet coil of the electromagnetic actuator 10, is connected in series with the ohmic resistance R_c.
  • a series circuit In parallel with the main inductance L_h, a series circuit is provided which has a leakage inductance L_ ⁇ and a further ohmic resistance R_w *.
  • the further ohmic resistance R_w * is an eddy current resistance of the electromagnetic actuator 10 translated to the side of the magnet coil.
  • the magnetizing current i_m is decisive for the generation of a magnetic force of the electromagnetic Actuator 10, which is used to move the valve needle of the fuel injector 100.
  • the eddy current i_w * contributes in a manner known per se to the electrical power loss of the electromagnetic actuator 10.
  • FIG. 13 shows a time profile of the currents described above through the magnetic circuit according to FIG Figure 2 .
  • the control voltage u is then set to a lower value.
  • the occurrence of magnetizing currents i_m that do not vanish at the beginning t_0 of the control can, for example, result from the fact that a the previous control process was ended so shortly before the beginning t_0 that the entire magnetic field of the leakage inductance L_ ⁇ has not already decayed.
  • the eddy current curve i_w * 2 that is established here is also in Figure 4 illustrated.
  • the magnetizing current i_m3 can also have an even greater value at the activation start time t_0 than is the case with the magnetizing current profile i_m2 is the case.
  • the reason for this can be, for example, a particularly short pause between two successive control processes of the electromagnetic actuator 10, so that at the control start time t_0 of the control process under consideration, a relatively large amount of energy is still stored in the magnetic field of the leakage inductance L_ ⁇ .
  • the coil current i_c3 accordingly reaches the specifiable setpoint value l_boos the earliest.
  • the corresponding eddy current curve is illustrated by the reference symbol i_w * 3.
  • a particularly simple and efficient way of obtaining information about the state of the magnetic circuit 11 of the electromagnetic actuator 10 is to determine a magnetization parameter that characterizes a magnetization current i_m that flows through the primary inductance L_h at the beginning t_0 of the control process.
  • this magnetization parameter can advantageously be used directly to modify the control of the electromagnetic actuator 10, that is to say in particular the control voltage u.
  • the temporal course of the control voltage u can be modified as a function of the magnetization parameter in such a way that, regardless of the actual value of the magnetization current i_m at the time t_0, the same operating behavior of the electromagnetic actuator 10 and thus, for example, the same injection quantity when the fuel injection valve 100 is operated ( Figure 1 ) results.
  • the magnetization parameter can be determined particularly efficiently as a function of a time profile of the coil current i_c flowing through the magnet coil of the electromagnetic actuator 10.
  • the state of the magnetic circuit 11 is determined based on a model as a function of at least one control variable for the electromagnetic actuator 10.
  • the model 200 shown can be used, which can be used, for example, by a corresponding computer program in a processing unit of the control unit 20 Figure 1 ) is implemented.
  • input variables E1, E2 are fed to the model 200.
  • the input variables E1, E2 can, for example, be parameters of the last fuel injection that are present in the control unit 20. Furthermore, the input variables E1, E2 can also include desired properties of the subsequent injection.
  • the model 200 according to the invention uses this to determine parameters for the control of the subsequent injection, which are, for example, a time profile of the control voltage u ( Figure 2 ) can act.
  • the model 200 according to the invention can be made available by making metrologically recorded operating parameters of the electromagnetic actuator 10 available, which are shown in FIG Figure 5 are symbolized by the reference symbol M, can be adapted during its operation.
  • the metrologically recorded variables M can be, for example, the control voltage u, the control current I, from which further variables can be determined, for example an opening time and / or a closing time and / or a flight duration of a movable component of the fuel injection valve 100, which during the activation of the fuel injection valve performs a ballistic trajectory.
  • the model 200 From the input variables E1, E2, M supplied to it, the model 200 according to the invention forms output variables A for controlling the electromagnetic actuator 10, which can be, for example, the time profile of the control voltage u.
  • a particularly precise control of the electromagnetic actuator 10 can be realized.
  • an activation of the electromagnetic actuator 10 can thereby advantageously be realized in which various activation processes are carried out in quick succession.
  • the pause times between the adjacent control processes are so short that the magnetic field of the leakage inductance L_ ⁇ has not already completely broken down again until a subsequent control process begins.
  • a non-vanishing magnetization current I_m results at the point in time t_0, which according to the invention is advantageously taken into account in the formation of the control variables for the subsequent control process.
