Description
Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb einer elektromechanischen Stelleinheit, die im wesentlichen aus einer elektronischen Steuereinheit und mindestens einem Elektromotor gebildet wird, wobei der Elektromotor von der elektronischen Steuereinheit mit Hilfe einer Pulsweitenmodulierung der Versorgungsspannung angesteuert wird und eine Bordnetzspannung an ihm anliegt. Außerdem betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The The present invention relates to a method of operating an electromechanical Actuator, which consists essentially of an electronic control unit and at least one electric motor is formed, wherein the electric motor from the electronic control unit using pulse width modulation the supply voltage is controlled and a vehicle electrical system voltage attached to him. Furthermore the invention relates to a device for carrying out the Process.

Es ist daher Aufgabe der vorliegenden Erfindung ein Verfahren zu entwickeln, das eine elektromechanische Stelleinheit derart ansteuert, dass unabhängig von Spannungsschwankungen des Bordnetzes ein Betrieb mit geringer Geräuschentwicklung realisierbar ist.It It is therefore an object of the present invention to develop a method which drives an electromechanical actuating unit in such a way that independently From voltage fluctuations of the electrical system, a low-power operation noise is feasible.
Diese Aufgabe wird verfahrensmäßig dadurch gelöst, dass der Elektromotor derart angesteuert wird, dass unabhängig vom aktuellen Wert der Bordnetzspannung die Drehzahl des Elektromotors und das vom Elektromotor zur Verfügung gestellte Drehmoment konstant sind.These Task is procedurally characterized solved, that the electric motor is controlled such that regardless of current value of the vehicle electrical system voltage, the speed of the electric motor and the torque provided by the electric motor constant are.
Dabei ist vorgesehen, dass die Versorgungsspannung des Elektromotors aus einem Produkt eines Faktors mit einem Quotienten aus Nominalspannung des Bordnetzes und dem aktuellen Wert der Bordnetzspannung gebildet wird, d.h. dass die Versorgungsspannung des Elektromotors durch die Gleichung bestimmt wird, sodass sichergibt.It is provided that the supply voltage of the electric motor is formed from a product of a factor with a quotient of nominal voltage of the electrical system and the current value of the vehicle electrical system voltage, ie that the supply voltage of the electric motor by the equation it is determined so results.
Eine besonders vorteilhafte Weiterbildung sieht vor, dass der Faktor derart ausgelegt wird, dass der Elektromotor bei einer Nominalspannung von vorzugsweise 14V ein für Feststellbremsvorgänge ausreichend großes Drehmoment zur Verfügung stellt und gleichzeitig eine Reduzierung des Laufgeräusches des Elektromotors sicherstelltA Particularly advantageous development provides that the factor is designed such that the electric motor at a nominal voltage of preferably 14V a for Parking brake operations big enough Torque available provides while reducing the running noise of the Electric motor ensures
Die Aufgabe wird außerdem erfindungsgemäß dadurch gelöst, dass Mittel vorhanden sind, die den Elektromotor derart ansteuern, dass unabhängig vom aktuellen Wert der Bordnetzspannung die Drehzahl des Elektromotors und das vom Elektromotor zur Verfügung gestellte Drehmoment konstant sind.The Task will as well according to the invention thereby solved, that means are present which drive the electric motor in such a way, that independent From the current value of the vehicle electrical system voltage, the speed of the electric motor and the torque provided by the electric motor constant are.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert, dessen einzige Figur ein schematisch dargestelltes Schaltbild eines hydraulischen Bremssystems zeigt, das eine elektromechanische Feststellbremse zur Durchführung von Feststellbremsvorgängen aufweist und an der das erfindungsgemäße Verfahren durchführbar istThe Invention will be related to an embodiment in the context closer with the enclosed drawing explains the single figure is a schematic diagram of a hydraulic braking system shows that an electromechanical parking brake to carry out of parking brake operations and at which the method according to the invention can be carried out
