Abstract
(DE)
Die Erfindung betrifft eine Steuereinheit zum Steuern eines Motors einer Ölpumpe. Die Steuereinheit umfasst eine Empfangseinheit, die eingerichtet ist, einen Solldruck zu empfangen; eine erste Bestimmungseinheit, die eingerichtet ist, ein Drehmoment aus dem Solldruck und einer Drehzahl des Motors über ein erstes Kennfeld zu bestimmen; eine zweite Bestimmungseinheit, die eingerichtet ist, einen Motor-Phasenstrom aus dem bestimmten Drehmoment über ein zweites Kennfeld zu bestimmen; und eine Ausgabeeinheit, die eingerichtet ist, den bestimmten Motor-Phasenstrom auszugeben.
(EN)
The invention relates to a control unit for controlling a motor of an oil pump. The control unit comprises a receiver unit which is configured to receive a setpoint pressure; a first determining unit which is configured to determine a torque from the setpoint pressure and from a rotational speed of the motor using a first characteristic map; a second determining unit which is configured to determine a motor phase current from the determined torque using a second characteristic map; and an output unit which is configured to output the determined motor phase current.
(FR)
L'invention concerne une unité de commande destinée à commander un moteur d'une pompe à huile. L'unité de commande comprend une unité de réception qui est configurée pour recevoir une pression de consigne ; une première unité de détermination qui est configurée pour déterminer un couple à partir de la pression de consigne et à partir d'une vitesse de rotation du moteur à l'aide d'une première carte de caractéristiques ; une seconde unité de détermination qui est configurée pour déterminer un courant de phase de moteur à partir du couple déterminé à l'aide d'une seconde carte de caractéristiques ; et une unité d'émission qui est configurée pour émettre le courant de phase de moteur déterminé.
