Abstract
(DE)
Verfahren zur Bestimmung der Förderleistung oder der Betätigungshäufigkeit einer Fluidpumpe (1,1'), insbesondere Hydraulikpumpe, in einem elektronischen Druckrege laggregat (6), wobei dieses neben einer durch analogisierte Ventilansteuerung betätigten Druckkreisregelung ein Pumpenleistungseinstellungsmittel zur Einstellung der Förderleistung der Hydraulikpumpe (1) umfasst, bei dem die Bewegungshäufigkeit des mechanischen Pumpwerks über Druckfluktuationen des Förderfluids bestimmt wird, wobei die Fluktuationen an Hand von Änderungen des magnetischen Flusses im Bereich des Ansteuermagnetfelds eines elektromagnetisch angesteuerten Fluidventils (2, 2' ) ermittelt werden. Die Erfindung betrifft auch die Verwendung des vorstehend beschriebenen Verfahrens in Kraftfahrzeugbremsenregelungssystemen.
(EN)
The invention relates to a method for determining the flow rate or the actuation frequency of a fluid pump (1,1'), particularly a hydraulic pump, in an electronic pressure control unit (6), wherein the same comprises a pump rate adjusting means for adjusting the flow rate of the hydraulic pump (1), in addition to a pressure cycle controller actuated via an analogized valve actuator, wherein the movement frequency of the mechanical pump station is determined via pressure fluctuations of the pumped fluid, wherein the fluctuations are ascertained based on changes of the magnetic flow in the region of the actuation magnetic field of an electromagnetically actuated fluid valve (2, 2' ). The invention further relates to the use of the above-described method in motor vehicle brake control systems.
(FR)
L'invention concerne un procédé permettant de déterminer la capacité de refoulement ou la fréquence d'actionnement d'une pompe à fluide (1, 1'), notamment une pompe hydraulique, dans un organe de régulation de pression (6) électronique, ce dernier comprenant, outre une régulation de circuit hydraulique actionné par commande de soupape analogué, un élément d'ajustement de capacité de pompage pour ajuster la capcacité de refoulement de la pompe hydraulique (1). Selon ce procédé, la fréquence de mouvement du système de pompage mécanique est établie par l'intermédiaire des variations de pression du fluide refoulé, lesdites variations étant déterminées sur la base des modifications de flux magnétique dans la zone du champ magnétique de commande d'une soupape hydraulique (2, 2') à commande électromagnétique. L'invention concerne également l'utilisation du procédé décrit dans des systèmes de régulation de freinage de véhicules automobiles.
