Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Motoransteuerung mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass bei der Ansteuerung eines Motors ein mittels des Klangsignals des Klangsignalgenerators erzeugtes zusätzliches Betriebsgeräusch erzeugt wird, das die als störend empfundenen Geräuschanteile des gewöhnlichen Betriebsgeräusches des Motors überlagert. Dadurch wird eine kostengünstige Lösung geschaffen, mit der beliebige, insbesondere als angenehm empfundene, Betriebsgeräusche des Motors erzeugt werden können.The Motor control according to the invention the features of the main claim has the advantage that in the Control of a motor by means of the sound signal of the sound signal generator generated additional Operating noise generated that will be annoying perceived noise components of the ordinary Operating noise of the Motors superimposed. This will be a cost effective solution created, with any, especially perceived as pleasant, operating noise of the engine can be generated.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Hauptanspruch angegebenen Motoransteuerung möglich.By in the subclaims listed activities are advantageous developments of specified in the main claim Motor control possible.
Vorzugsweise ist der Motor ein Elektromotor.Preferably the engine is an electric motor.
Vorteilhaft ist es, dass das Klangsignal ein Klangstromsignal ist, dass das Energieversorgungssignal ein Energieversorgungs-Gleichstromsignal ist und dass der Mischer das Ansteuerungssignal entsprechend der Summe des Addierens des Pegels des Klangstromsignals zu dem Pegel des Energieversorgungs-Gleichstromsignals erzeugt. In diesem Fall überlagert der Mischer dem Energieversorgungs- Gleichstromsignal das Klangstromsignal. Während das Energieversorgungs-Gleichstromsignal den Elektromotor zum Antreiben durchfließt, dient das Klangstromsignal zum Erzeugen eines synthetischen Betriebsgeräusches des Motors, der vergleichbar einem Lautsprecher angesteuert wird. Die Überlagerung kann z.B. innerhalb einer Leistungsendstufe realisiert werden.Advantageous it is that the sound signal is a sound current signal that the Power supply signal, a power supply DC signal is and that the mixer, the drive signal according to the Sum of adding the level of the sound stream signal to the level of the power supply DC signal. In this case superimposed the mixer sends the power signal to the power supply DC signal. While that Power supply dc signal the electric motor to power flows through the sound current signal serves to generate a synthetic operating noise of the Motors, which is controlled similar to a speaker. The overlay can e.g. be realized within a power output stage.
In vorteilhafter Weise gibt der Klangsignalgenerator das Klangsignal so vor, dass das künstliche Betriebsgeräusch des Elektromotors einem Betriebsgeräusch eines sich gleichmäßig drehenden Elektromotors entspricht. Bei einer sich ändernden Motorlast, die durch unterschiedliche Gewichte, Schwergängigkeiten, Kinematiken und dgl. hervorgerufen werden kann, wird dadurch der Eindruck einer gleichmäßigen Betätigung erzeugt. Durch eine Verschiebung des Frequenzspektrums des Klangsignals, insbesondere eines langsamen An- oder Absteigens der Frequenz des Klangsignals, lassen sich dadurch auch dynamische Effekte realisieren, was beim Anfahren und Abbremsen eines Verstellantriebs bei der fremdkraftbetätigten Bewegung von Fenstern, Dachteilsystemen, Sitzverstellungen und dgl. zur Anwendung kommen kann.In Advantageously, the sound signal generator gives the sound signal so before that the artificial operating noise of the Electric motor operating noise a uniformly rotating Electric motor corresponds. At a changing engine load caused by different weights, bindings, kinematics and Like. Can be caused, thereby the impression of a generated uniform actuation. By shifting the frequency spectrum of the sound signal, in particular a slow increase or decrease in the frequency of Sound signal, thereby also dynamic effects can be realized, what when starting and braking an adjusting drive in the power-operated movement of windows, roof systems, seat adjusters and the like. For use can come.
In vorteilhafter Weise gibt der Klangsignalgenerator das Klangsignal so vor, dass das künstliche Betriebsgeräusch des Elektromotors einem Betriebsgeräusch eines sich mit konstanter Drehzahl drehenden Elektromotors entspricht. Durch die drehzahlunabhängige Festlegung der Frequenzanteile des Klangsignals kann der Eindruck eines hochwertig klingenden Motors mit konstanter Frequenz erzeugt werden. Dadurch kann ein kostengünstiger Motor ohne Drehzahlkonstanz eingesetzt werden, ohne dass unangenehme Geräuschvariationen wahrnehmbar sind.In Advantageously, the sound signal generator gives the sound signal so before that the artificial operating noise of the Electric motor operating noise corresponds to a rotating at constant speed electric motor. By the speed independent Determining the frequency components of the sound signal can be the impression a high-quality sounding engine with a constant frequency can be generated. This can be a more cost effective Motor can be used without speed constancy without being unpleasant sound variations are perceptible.
Dabei ist es besonders vorteilhaft, dass der Klangsignalgenerator das Klangsignal als ein Klangsignal erzeugt, das in Bezug auf eine Grundfrequenz aus harmonischen Oberwellen zusammengesetzt ist, wobei die Grundfrequenz im Bereich von etwa 50 Hz bis etwa 70 Hz liegen kann. Auf diese Weise kann ein künstliches Betriebsgeräusch des Elektromotors erzeugt werden, das als besonders angenehm empfunden wird.there it is particularly advantageous that the sound signal generator the Sound signal generated as a sound signal, with respect to a fundamental frequency harmonic waves is composed, the fundamental frequency may range from about 50 Hz to about 70 Hz. To this Way can be an artificial one operating noise be generated by the electric motor, which felt particularly pleasant becomes.
Vorteilhaft ist es, dass ein Drehzahl-Erfassungsmittel vorgesehen ist, das zum Erfassen einer Drehzahl des Elektromotors dient und ein die momentane Drehzahl des Elektromotors anzeigendes Drehzahlsignal an den Klangsignalgenerator ausgibt, und dass der Signalgenerator das Klangsignal in Abhängigkeit von dem Drehzahlsignal erzeugt. Dadurch kann das mittels des Klangsignals hervorgerufene Betriebsgeräusch des Elektromotors, insbesondere hinsichtlich der Frequenz, der Motordrehzahl angepasst werden, um eine akustische Rückmeldung zur Motordrehzahl zu geben. Dies ist von besonderem Vorteil, wenn Verstellantriebe mit zwei oder mehr Geschwindigkeiten, insbesondere zur Sitzverstellung, realisiert werden.It is advantageous that a speed-detecting means is provided which serves to detect a rotational speed of the electric motor and a mo mentane speed of the electric motor indicating speed signal to the sound signal generator outputs, and that the signal generator generates the sound signal in response to the speed signal. As a result, the operating noise of the electric motor caused by the sound signal, in particular with regard to the frequency, of the engine speed can be adjusted in order to give an acoustic feedback to the engine speed. This is of particular advantage when adjustment drives with two or more speeds, in particular for seat adjustment, can be realized.
