Description
Die Erfindung betrifft ein Verfahren zur Steuerung eines Elektromagnetventils, insbesondere für ein Automatikgetriebe eines Kraftfahrzeugs, gemäß dem Oberbegriff des Patentanspruchs 1.The Invention relates to a method for controlling a solenoid valve, especially for one Automatic transmission of a motor vehicle, according to the preamble of the claim 1.

der
Aufgabe der Erfindung ist es demgegenüber, ein Verfahren zur Steuerung eines Elektromagnetventils vorzuschlagen, mittels welchem ein schnelles Ansprechverhalten und eine hohe Einstellgenauigkeit des Elektromagnetventils ermöglicht wird.task the invention it is in contrast, a To propose method for controlling a solenoid valve, by means of which a fast response and a high setting accuracy of the solenoid valve allows becomes.
Erfindungsgemäß wird die Aufgabe durch ein Verfahren nach Anspruch 1 gelöst.According to the invention Problem solved by a method according to claim 1.
Erfindungsgemäß wird die Periodendauer des Ansteuersignals von der Steuerungseinrichtung in Abhängigkeit von einem Einschaltanteil des Ansteuersignals verändert.According to the invention Period duration of the drive signal from the control device in dependence changed by a switch-on of the drive signal.
Bei einer pulsweitenmodulierten Ansteuerung wird ein Sollwert am Elektromagnetventil, beispielsweise ein Soll-Strom, einge stellt, indem ein Verhältnis zwischen einem Einschaltanteil und einem Ausschaltanteil der Versorgungsspannung innerhalb einer Periodendauer variiert wird. Die Taktfrequenz des Ansteuersignals entspricht dabei dem Reziprokwert der in Sekunden angegebenen Periodendauer. Bei Ansteuerverfahren nach dem Stand der Technik ist die Summe der Einschalt- und der Ausschaltzeit, die sogenannte Periodendauer, konstant. Die Periodendauer kann beispielsweise 1 ms betragen; die Taktfrequenz also 1000 Hz. Durch diese Ansteuerung führt ein Anker des Elektromagnetventils Mikrobewegungen aus, wodurch bei einer Positionsänderung lediglich Gleitreibung und keine erheblich höhere Haftreibung überwunden werden muss.at a pulse width modulated control is a setpoint at the solenoid valve, For example, a target stream, adjusted by a ratio between a switch-on and a Ausschaltanteil the supply voltage is varied within a period. The clock frequency of the Drive signal corresponds to the reciprocal of the seconds specified period. In driving method according to the state The technique is the sum of the turn-on and turn-off times, the so-called period duration, constant. The period can, for example 1 ms; the clock frequency thus 1000 Hz. By this control introduces Anchor of the solenoid valve micro-movements off, causing at a position change only sliding friction and no significantly higher static friction overcome must become.
Die spezifischen Eigenschaften eines Hydrauliksystems, in welchem Elektromagnetventile Verwendung finden, insbesondere die Steifigkeit und die Dämpfung, sind nicht konstant, sondern ändern sich erheblich bei verschiedenen Betriebsgrößen des Elektromagnetventils, insbesondere bei verschiedenen Einschaltanteilen des Ansteuersignals. Durch eine Änderung der Periodendauer in Abhängigkeit vom Einschaltanteil wird diesen unterschiedlichen Eigenschaften Rechnung getragen. Damit kann die Periodendauer optimal an die Eigenschaften des Hydrauliksystems angepasst und ein schnelles Ansprechverhalten und eine hohe Einstellgenauigkeit erreicht werden. Die Hysterese des Elektromagnetventils wird damit sehr gering.The specific characteristics of a hydraulic system in which solenoid valves use especially the stiffness and the damping, are not constant, but change considerably with different operating variables of the electromagnetic valve, in particular with different switch-on components of the drive signal. By a change the duration of the period as a function of Switching factor will take into account these different characteristics carried. Thus, the period can be optimally adapted to the properties adapted to the hydraulic system and a fast response and a high setting accuracy can be achieved. The hysteresis of the solenoid valve is thus very low.
Hydrauliksysteme neigen teilweise sehr stark zu Druckschwingungen. Die Ansteuerung und die damit hervorgerufenen Reaktionen eines Elektromagnetventils stellen Anregungen des Hydrauliksystems dar. Sie haben außerdem einen Einfluss auf Resonanzfrequenzen des Hydrauliksystems. Die genannten Anregungen können Druckschwingungen auslösen. Die Periodendauer bei einer pulsweitenmodulierten Ansteuerung ist eine entscheidende Eigenschaft der Ansteuerung. Durch Anpassung der Periodendauer und damit der Ansteuerung an die spezifischen Eigenschaften, insbesondere Steifigkeit und Dämpfung, können Druckschwingungen im Hydrauliksystem vermieden werden.hydraulic systems sometimes very strongly tend to pressure oscillations. The control and the resulting reactions of a solenoid valve represent suggestions of the hydraulic system. You also have one Influence on resonance frequencies of the hydraulic system. The mentioned Suggestions can Trigger pressure oscillations. The period duration in a pulse width modulated control is a decisive feature of the control. By adaptation the period and thus the control to the specific Properties, in particular stiffness and damping, can pressure oscillations in the hydraulic system be avoided.

Ein einzustellender Druck oder ein einzustellender Durchfluss durch das Magnetventil ist vom Ist-Ventilstrom abhängig. Der Ist-Ventilstrom ist abhängig vom Einschaltanteil, der Versorgungsspannung, einem ohmschen Widerstand und einer Induktivität der Spule des Elektromagnetventils. Der Ist-Ventilstrom steigt bei steigendem Einschaltanteil, steigender Versorgungsspannung und/oder sinkendem Widerstand. Der Widerstand der Spule ist abhängig von der Temperatur. Damit ist der Ist-Ventilstrom auch indirekt von der Temperatur der Spule und damit von der Temperatur des Arbeitsmediums abhängig. Da der Widerstand mit steigender Temperatur ansteigt, sinkt der Ist-Ventilstrom mit steigender Temperatur des Arbeitsmediums und gleichbleibender Versorgungsspannung und gleichbleibendem Einschaltanteil ab..On pressure to be set or flow to be set The solenoid valve is dependent on the actual valve current. The actual valve current is dependent from the switch-on component, the supply voltage, an ohmic resistor and an inductance the coil of the solenoid valve. The actual valve current increases rising switch-on, rising supply voltage and / or sinking resistance. The resistance of the coil depends on the temperature. Thus, the actual valve current is also indirect from the temperature the coil and thus dependent on the temperature of the working medium. There the resistance increases with increasing temperature, the actual valve current decreases with increasing temperature the working medium and constant supply voltage and constant starting proportion from ..
Auf Grund der genannten Abhängigkeiten muss der Ist-Ventilstrom aufwändig berechnet oder gemessen werden. Der Einschaltanteil liegt dagegen ohne vorherige Berechnung oder Messung in der Steuerungseinrichtung vor. Die Umsetzung der Veränderung der Periodendauer in Abhängigkeit vom Einschaltanteil ist damit einfacher in der Steuerungseinrichtung umsetzbar.On Reason of said dependencies must the actual valve current costly calculated or measured. The switch-on is, however, without previous calculation or measurement in the control device. The implementation of the change the period in dependence From the turn-on is thus easier in the control device implemented.
Das Elektromagnetventil kann als ein sogenanntes Sitzventil ausgeführt sein, welches über einen Übertrittsquerschnitt zur Beeinflussung von Druck- und/oder Strömungsverhältnissen verfügt. Mittels eines Ankers, welcher von der Spule bewegt werden kann, ist der Übertrittsquerschnitt veränderbar. Bei einer so gearteten Ausführung des Elektromagnetventils wird die Periodendauer verkürzt, wenn sich der Anker in der Nähe des sogenannten Ventilsitzes befindet, welcher zusammen mit dem Anker den Übertrittsquerschnitt bestimmt.The Solenoid valve can be designed as a so-called seat valve, which over a crossover cross section has an influence on pressure and / or flow conditions. through An armature that can be moved by the coil is the crossover cross section variable. With such a kind execution of the solenoid valve, the period is shortened when the anchor nearby the so-called valve seat is located, which together with the Anchor the crossover cross section certainly.
Die pulsweitenmodulierte Ansteuerung führt zu Mikrobewegungen des Ankers, wobei die Amplitude der Mikrobewegungen um so größer ist, je länger die Periodendauer ist. Befindet sich der Anker in der Nähe des Ventilsitzes, kann es damit zu einem Aufschlagen des Ankers auf den Ventilsitz, zu sogenannten Sitzprellern kommen. Dies verursacht ungewollte Geräusche und stellt außerdem eine Anregung des Hydrauliksystems dar, was zu Druckschwingungen führen kann. Durch eine kurze Periodendauer wird die Amplitude der Mikrobewegungen verkürzt und ihre Frequenz erhöht. Damit können Sitzpreller wirkungsvoll verhindert werden.The Pulse width modulated control leads to micro movements of the Anchor, where the amplitude of the micromotion is greater, the longer the Period is. Is the armature near the valve seat, it can thus be a knocking of the armature on the valve seat, come to so-called seat bouncers. This causes unwanted noise and as well an excitation of the hydraulic system, which can lead to pressure oscillations. A short period of time will cause the amplitude of the micromotion shortened and their frequency increases. With that you can Sitzpreller be effectively prevented.
Bei einem Elektromagnetventil zur Druckregelung mit einer sogenannten steigenden Kennlinie steigt der Druck mit steigendem Ist-Strom und damit steigendem Einschaltanteil an. Bei steigendem Druck verringert sich der genannte Übertrittsquerschnitt. Damit wird bei einem so gearteten Elektromagnetventil die Periodendauer bei steigendem Einschaltanteil verkürzt.at a solenoid valve for pressure control with a so-called rising characteristic increases the pressure with increasing actual current and thus increasing starting share. Reduced with increasing pressure the said crossover cross section. Thus, the period is in such a solenoid valve Shortened as the starting percentage increases.
Für ein schnelles Ansprechverhalten und eine hohe Einstellgenauigkeit des Elektromagnetventils ist es vorteilhaft, wenn die Periodendauer des Ansteuersignals mit steigender Temperatur des Arbeitsmediums kleiner wird. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass diese Abhängigkeit automatisch enthalten ist. Da der Widerstand der Spule mit steigender Temperatur ansteigt, vergrößert sich bei gleichem Ist-Ventilstrom der Einschaltanteil. Damit verkürzt sich die Periodendauer automatisch bei steigender Temperatur.For a quick Responsiveness and high setting accuracy of the solenoid valve it is advantageous if the period of the drive signal with increasing temperature of the working medium is smaller. Another Advantage of the method according to the invention is that dependence is included automatically. As the resistance of the coil increases with increasing Temperature increases, increases at the same actual valve current, the switch-on. This shortens the period automatically when the temperature rises.
