Abstract
(DE) Es wird ein Verfahren zum Steuern einer Fahrdynamikregelungsvorrichtung (10), die zum Beeinflussen des Bremsens von Rädern (50, 52) eines Kraftfahrzeugs ausgebildet ist, vorgeschlagen, wobei die Fahrdynamikregelungsvorrichtung (10) eine Pumpe (20) mit mindestens zwei Pumpenelementen (22, 23) zum Fördern einer Bremsflüssigkeit und einen Elektromotor (30) umfassend einen Rotor und einen Stator zum Antreiben der Pumpenelemente (22, 23) aufweist, wobei das Verfahren folgende Schritte umfasst: Erfassen der Position des Rotors relativ zu dem Stator; und Einstellen einer Idealposition des Rotors relativ zu dem Stator, wobei die Summe der Drehmomente zum Bewegen der Pumpenelemente (22, 23) in der Idealposition unterhalb eines vorgegebenen Drehmomentgrenzwerts liegt, insbesondere minimal ist.
(EN) The invention relates to a method for controlling a drive dynamic control device (10) which is designed to influence the brakes of wheels (50, 52) of a motor vehicle. The drive dynamic control device (10) has a pump (20) with at least two pump elements (22, 23) for pumping a braking fluid and an electric motor (30) comprising a rotor and a stator for driving the pump elements (22, 23). The method has the following steps: detecting the position of the rotor relative to the stator; and setting an ideal position of the rotor relative to the stator, wherein the sum of the torques for moving the pump elements (22, 23) in the ideal position lies below a specified torque threshold and is minimal in particular.
(FR) L'invention concerne un procédé servant à commander un dispositif de régulation de dynamique de conduite (10), qui est réalisé pour influencer le freinage de roues (50, 52) d'un véhicule automobile. Le dispositif de régulation de dynamique de conduite (10) comporte une pompe (20) pourvue d'au moins deux éléments de pompe (22, 23) servant à refouler un liquide de frein et un moteur électrique (30) comprenant un rotor et un stator servant à entraîner les éléments de pompe (22, 23). Le procédé comprend des étapes suivantes consistant à : détecter la position du rotor par rapport au stator ; et régler la position du rotor par rapport au stator. La somme des couples de rotation servant à déplacer les éléments de pompe (22, 23) est inférieure dans la position idéale à une valeur limite de couple de rotation spécifiée, en particulier est minimale.
