Abstract
Description
Die Erfindung betrifft eine Schaltungsanordnung zur Energieversorgung einer elektrischen Servolenkung gemäß dem Oberbegriff des Anspruchs 1The The invention relates to a circuit arrangement for power supply an electric power steering according to the preamble of the claim 1
Zunehmend finden in Kraftfahrzeugen elektrische Servolenkungen Verwendung, welche ihre elektrische Energie aus einem Bordspannungsnetz des Kraftfahrzeugs entnehmen. Elektrische Servolenkungen finden derzeit aufgrund der begrenzten Leistung des Bordspannungsnetzes vorwiegend in Klein- und Mittelklasse-Fahrzeugen Einsatz. Erhöhte Lenkleistung, welche insbesondere in oberen Fahrzeugklassen aufgrund der hohen Achslasten gefordert sind, können nicht oder nur kurzzeitig aufgrund der beschränkten Leistungsfähigkeit eines herkömmlichen Fahrzeugbordnetzes erreicht werdenIncreasingly find in electric vehicles electric power steering use, which their electrical energy from an on - board voltage network of Remove motor vehicle. Electric power steering systems are currently finding due to the limited power of the on-board voltage network predominantly in small and middle-class vehicles use. Increased steering power, which especially in upper vehicle classes due to the high Axle loads are required not or only for a short time due to limited performance a conventional one Vehicle electrical system can be achieved
Aus dem Stand der Technik sind ferner so genannte Überlagerungslenkung bekannt. Lenkungen dieser Art stellen selbsttätig einen von einem Fahrer vorgegebenen Lenkwinkel additiv einen Zusatzlenkwinkel zu und verändern damit ein Gesamt-Lenkübersetzungsverhältnis. Dadurch können sehr hohe Radlenkwinkel-Geschwindigkeiten erreicht werden. Deshalb werden in diesen Systemen vorwiegend hydraulische Servo-Steller eingesetzt. Lediglich die additive Zustellung des Lenkwinkes erfolgt mittels eines entsprechend dimensionierten Elektromotors und einem Überlagerungsgetriebe, meist in Form eines Planeten- oder Pulsatorgetriebes.Out The prior art also known as so-called superposition steering. Steering systems of this kind automatically set one by a driver given steering angle additive to an additional steering angle and change it an overall steering ratio. Thereby can very high wheel steering angle speeds can be achieved. Therefore Hydraulic servo controllers are predominantly used in these systems. Only the additive delivery of the steering angle by means of a suitably dimensioned electric motor and a superposition gear, usually in the form of a planetary or Pulsatorgetriebes.
Neueste Entwicklungen Kombinieren diese unterschiedlichen Lenksysteme miteinander, wobei die hydraulische Servostufe durch eine elektrische Servostufe ersetzt wird. Die additive Zustellung des Zusatzlenkwinkels wird mittels eines entsprechend dimensionierten Überlagerungs-Elektromotors übernommen und die eigentliche Servo-Unterstützung erfolgt mit einen entsprechend ausgelegten Elektromotor der elektrischen Servolenkung.Latest Developments Combine these different steering systems, wherein the hydraulic servo stage replaced by an electric servo stage becomes. The additive delivery of the additional steering angle is by means of taken over a correspondingly dimensioned overlay electric motor and the actual servo support is done with an accordingly designed electric motor of the electric power steering.
Die Bedeutung des Begriffs „elektrische Servolenkung" schließt im Folgenden auch derartige Lenksysteme mit ein.The Meaning of the term "electric Power steering "concludes below also such steering systems with a.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung und ein Verfahren zur Steigerung der Abgabeleistung einer elektrischen Servolenkung zu schaffen, bei dem ein vorhandenes Fahrzeugbordnetz weitgehend unverändert beibehalten werden kann.task It is the object of the present invention to provide an apparatus and a method to increase the power output of an electric power steering to create an existing vehicle electrical system largely unchanged can be maintained.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 und den Merkmalen des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen finden sich in den UnteransprüchenThese Task is with the features of claim 1 and the features of claim 9 solved. advantageous Embodiments can be found in the subclaims
Die erfindungsgemäße Schaltungsanordnung zur Erhöhung der Nutzleistung einer elektrischen Servolenkung sieht vor, einem regelbaren Bordspannungsnetz einen Hochlastzweig zuzuordnen wobei dieser mittels eines Entkoppelungsglieds dem Bordspannungsnetz beliebig zu- und abschaltbar ist.The inventive circuit arrangement to increase the net output of an electric power steering system provides a adjustable on-board voltage network to assign a high-load branch this by means of a Entkoppelungsglieds the on-board voltage network arbitrarily can be switched on and off.
Im Hochlastzweig sind wenigstens die Komponenten einer elektrischen Servolenkung angeordnet, welche einen erhöhten Bedarf an elektrischer Energie aufweisen, sowie ein Energiespeicher welcher auf ein gegenüber der Normspannung des Bordspannungsnetzes erhöhtes Spannungsniveau aufladbar ist.in the Hochlastzweig are at least the components of an electrical Power steering arranged, which increased the need for electrical Have energy, as well as an energy storage which on a relation to the Standard voltage of the on-board voltage system increased voltage level rechargeable is.
Dadurch dass der Hochlastzweig im Wesentlichen während der Betriebszeit eine gegenüber dem Niveau des Bordspannungsnetzes erhöhte Spannung aufweist, lässt sich eine signifikante Leistungssteigerung der elektrischen Servolenkung erreichen. Dabei wird als besonderen Vorteil angesehen, ein herkömmliches Bordnetzsystem im Wesentlichen unmodifiziert beizubehalten. Vorteilhaft Ausgestaltungen sind Gegenstand der UnteransprücheThereby that the high-load branch essentially during the operating time a across from The level of the on-board voltage network has increased voltage, can be a significant increase in power of the electric power steering to reach. It is considered a special advantage, a conventional wiring system essentially unmodified. Advantageous embodiments are the subject of the dependent claims

In einem herkömmlichen Bordspannungsnetz mit einer Nennspannung von 12 Volt schwankt die tatsächliche Spannung etwa im Bereich von etwa 11,5 V bis etwa 14,4 V, im folgenden Nennspannungsbereich genannt. Eine spannungsgeregelte Lichtmaschine oder ein Starter-Generator regelt das Spannungsniveau derart, dass die Spannung von etwa 14,4 V auch bei hohen Drehzahlen des Verbrennungsmotors im Wesentlichen nicht überschritten wird.In a conventional one On-board voltage network with a rated voltage of 12 volts fluctuates actual Voltage in the range of about 11.5 V to about 14.4 V, in the following Nominal voltage range called.
