Definitions

  • the invention relates to a method for regulating an opening and / or closing process of a solenoid valve according to the preamble of claim 1.
  • the known solenoid valve has an electromagnet arranged in a housing part, an axially movable armature which is guided in a slider and acted on by a closing spring, and a control valve member which moves with the armature and which cooperates with a valve seat of the solenoid valve and thus the fuel outflow from the control pressure chamber controls.
  • a solenoid valve for controlling an injection valve of an internal combustion engine is also known from DE 101 31 201 AI.
  • DE 196 07 073 AI describes a method and a device for controlling the movement of an armature of an electro- magnetic switching element (or a solenoid valve), which has an excitation winding, described.
  • a first setpoint value for the current can be specified from a first point in time and a second setpoint value for the current can be specified from a second point in time.
  • the second target value is less than, equal to or greater than the first target value and the second point in time lies before a third point in time at which the armature reaches its end position with a solenoid valve needle or the control valve member.
  • P -oblematic in general is that the control valve member or the armature has not yet been precisely regulated during the ballistic phase, that is to say during the flight phase.
  • the line resistance of the supply voltage is a factor that greatly impairs the flight phase, because a high internal resistance can lead to voltage fluctuations. Since the voltage measurement is usually carried out by averaging, voltage drops due to the internal resistance can hardly be determined. Exact current control at any discrete point in time is very complex since, for example, a separate processor would have to be made available for this. Due to these voltage fluctuations, however, the pulling and opening times of the armature or of the control valve element change, as a result of which a closing process or the ballistic phase of the armature disadvantageously cannot be reproduced exactly.
  • the time duration between the times of the previous opening and / or closing process is used as a controlled variable for regulating the current and / or voltage curve in the opening and / or closing process can advantageously precisely regulate the current curve.
  • the solenoid valve closes, the time at which the armature or the control valve member picks up and strikes is already detected, which means that the flight phase or the ballistic phase of the control valve member or the armature can be regulated in a simple manner by means of current - and voltage curve can be adjusted accordingly.
  • the flight phase of the control valve member is thus reproducible up to the point of impact and there is no complex regulation of the current value at any discrete point in time. As a result, production costs can be kept low.
  • the time of impact can also be recorded, as is known.
  • the total duration of the anchor's flight phase can be calculated using these variables. It can thus be reproducibly determined exactly how long the pull-in phase with a high voltage to accelerate the armature, the subsequent second phase with a lower voltage after exceeding a current threshold value until it opens (closing of the solenoid valve) and the holding phase after the opening time.
  • FIG. 1 shows a current flow diagram during the closing process of a solenoid valve with an increased internal resistance of the supply lines with and without a control according to the invention
  • 2 shows a flowchart of an embodiment of the control method according to the invention.
  • a solenoid valve (not shown here) for controlling the fuel injection of an internal combustion engine is known, for example, from DE 196 07 073 AI.
  • An excitation winding or coil of the solenoid valve is in series with a voltage source and at least one controllable switching means, for example a transistor, which is controlled by a control signal from a control signal.
  • the control signal is provided by a motor control.
  • the present exemplary embodiment shows a method for regulating an opening and / or closing process of the solenoid valve, the voltage source during the closing process of the solenoid valve, in which fuel is to be injected into the internal combustion engine, the excitation winding in three phases Pl, P2, P3 (see Fig. 1) supplied with a voltage which varies during each phase P1, P2, P3, as a result of which a control valve member is moved accordingly, in particular via an armature.
  • the voltage can also be modulated differently in the respective phases, for example.
  • a first voltage is applied at time T Be gi nn until a current threshold value, in the present exemplary embodiment numbered 14 amperes, is reached.
  • a current threshold value in the present exemplary embodiment numbered 14 amperes
  • the control valve member starts to move or is accelerated.
  • the voltage in phase P2 is reduced again in order not to accelerate the armature or the control valve member any further.
  • the voltage is kept constant in order to keep the control valve in the open state and the solenoid valve closed.
  • a current curve la is outlined without a temporal control of the phases P1 and P2.
  • a curve b shows a current waveform of the solenoid valve at nominal conditions or with an inventive temporal Einregelung particular phases Pl and P2 on the detected time points T Be beginning, nzug and t Au ftsch •
  • FIG. 2 shows a control method according to the invention as a flow diagram.
  • a step A marks the start of the method, in a step B the start values for the voltage conditions in the phases P1 and P2 are defined.
  • the energization of the solenoid valve begins at time T Be gi ⁇ m.
  • the corresponding voltage for phase P1 is then applied (step D).
  • the suit detection is carried out, ie the measurement of the time A n to g when the current value threshold is reached, after which in a step F the phase P2 is initiated by applying a further changed voltage.
  • a step G the impact detection follows, ie the measurement of the impact time T A schschiag, after which the phase P3 is initiated at a point H.
  • this phase P3 is characterized by an exact current control and represents the so-called holding phase of the solenoid valve.
  • the voltage is switched off quickly or the solenoid valve opens.
  • the resulting time behavior of the current curve remains in the required accuracy, as well as the injection behavior of the internal combustion engine, which is now constant regardless of mechanical and hydraulic disturbances.
  • the solution can easily be implemented by a computer program. An automatic compensation of aging effects and manufacturing variation of the solenoid valves is also achieved.
  • the flight time of the control valve member can be used to diagnose the internal combustion engine.
  • T Due to the constant pick-up and opening times T should be g / T _ impact of the valve of the respective physical beginning of injection is constant, and thus the fuel injected into the cylinder fuel amount, since the injection nozzle is acted upon in time always evenly with pressure.

Abstract

L'invention concerne un procédé permettant de réguler un processus d'ouverture et/ou de fermeture d'une électrovanne, par régulation du trajet d'un courant et/ou d'une tension qui parcourent ou alimentent une bobine de l'électrovanne, pour déplacer un élément de soupape de commande. Plusieurs instants du processus d'ouverture et/ou de fermeture sont détectés, qui résultent notamment de valeurs caractéristiques physiques du trajet du courant et/ou de l'électrovanne. Les grandeurs de régulation utilisées pour réguler le trajet du courant et/ou de la tension, lors du processus d'ouverture et/ou de fermeture, sont la durée temporelle entre les instants détectés du processus d'ouverture et/ou de fermeture précédent.
