Abstract
(DE)
Es wird ein Verfahren zur Steuerung einer Vakuumpumpe in der Vakuumversorgung eines Kraftfahrzeugs mit einer Ölversorgung zur Schmierung durch einen Antriebsmotor vorgeschlagen, wobei die Vakuumpumpe elektrisch betrieben ist und mit einer Steuerung verbunden ist, mit folgenden Schritten: Detektieren, ob der Antriebsmotor abgeschaltet wurde, Starten der Vakuumpumpe mit einer Drehzahl unter der Arbeitsdrehzahl, Detektion des aufgebrachten Drehmoments am BLDC-Motor, Abschalten bei Erreichung eines Schwellwertes des Drehmoments.
(EN)
The invention relates to a method for controlling a vacuum pump in the vacuum supply of a motor vehicle with an oil supply for lubrication by a drive motor, wherein the vacuum pump is operated electrically and is connected to a controller. The method comprising the following steps: detecting whether the drive motor is turned off; starting the vacuum pump at a rotational speed below the working speed; detecting the applied torque on the BLDC motor and turning off said pump when a threshold value of the torque is reached.
(FR)
Procédé de commande d'une pompe à vide située dans l'alimentation en vide d'un véhicule à moteur pourvu d'une alimentation en huile pour la lubrification à l'aide d'un moteur d'entraînement, la pompe à vide étant électrique et étant reliée à une commande. Ledit procédé comporte les étapes suivantes : détecter si le moteur d'entraînement a été arrêté, démarrer la pompe à vide à un régime inférieur au régime de travail, détecter le couple produit sur le moteur BLDC et arrêter ladite pompe après atteinte d’une valeur seuil de couple.
