Abstract
Description
Die Erfindung betrifft eine elektrische Servolenkung, insbesondere eine Hilfskraftlenkung für ein Fahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention relates to an electric power steering, in particular a Power steering system for a vehicle, according to the generic term of claim 1.
Die
Wankstabilisierungssysteme, die als Vertikaldynamiksteller durch die gezielte Verstellung der Radaufstandkräfte ein Fahrzeugwanken verhindern sollen, oder die aktive Verteilung des Antriebsmoments zwischen den Rädern einer Achse mit Hilfe von Traktionsstellern sind weitere Beispiele.roll stabilization systems, as a vertical dynamic actuator by the targeted adjustment of Radaufstandkräfte prevent vehicle rolling, or the active distribution of the drive torque between the wheels of an axle Help from traction actuators are other examples.
All diesen Systemen ist gemeinsam, dass in einem geschlossenen Regelkreis ein Fahrdynamikregler einen Aktuator beaufschlagt, der im Fahrzeug ein Aggregat in gewünschter Weise einstellt, wobei die Dynamik des Aggregats bzw. des Fahrzeugs und auch die Eigendynamik des Reglers zu berücksichtigen ist.Alles These systems have in common that in a closed loop a vehicle dynamics controller an actuator applied to the in the vehicle Aggregate sets in the desired manner, the dynamics of the unit or of the vehicle and also the momentum of the controller to take into account.
Mit zunehmender Anzahl an Assistenzsystemen nimmt aber die Komplexität zu, was dazu führt, dass zwar ein einzelnes Regelsystem für sich stabil ist, jedoch durch das Zusammenwirken der verschiedenen Systeme gegenseitige Beeinflussungen auftreten können, die sich unter anderem auf die Stabilität auswirken können.With However, the increasing number of assistance systems decreases the complexity too, which leads to a single rule system is stable for itself, but through the interaction of different systems may interact with each other, which, among other things, can affect stability.
Verschärft wird dieses Problem noch dadurch, dass die einzelnen Fahrdynamikregler zum Teil bei unterschiedlichen Herstellern entwickelt werden, sodaß das Zusammenspiel der Regler erst in einer möglicherweise späten Entwicklungsphase getestet werden kann. Die Folge kann eine Instabilität des Gesamtsystems aufgrund einer zu hohen Gesamtverstärkung sein, ein unakzeptables Einschwingverhalten oder ein Gegeneinander der Einzelregler. Zudem wird für jeden Regler Bauraum benötigt.tightened This problem is still caused by the fact that the individual driving dynamics controller be developed in part at different manufacturers, so that the Interaction of the controller only in a possibly late Development phase can be tested. The consequence can be an instability of the Overall system due to too high overall gain be an unacceptable transient response or a conflict the single controller. In addition, space is required for each controller.
Der Erfindung liegt die Aufgabe zugrunde, eine kompakte elektrische Servolenkung deren Betrieb auch im Zusammenspiel von mehreren Fahrdynamikreglern stabil ist, anzugeben.Of the Invention is based on the object, a compact electrical Power steering their operation also in the interaction of several vehicle dynamics controllers is stable.
Die Aufgabe wird mit einer Servolenkung mit den Merkmalen des Anspruchs 1 gelöst.The Task is with a power steering with the features of the claim 1 solved.
Dadurch dass eine einzige Steuer- und/oder Regelungseinrichtung die Ansteuerung zumindest eines Servomotors zur Bereitstellung einer Lenkhilfskraft und eines elektrischen Aktuators und/oder dessen Steuergerät für ein Wankstabilisierungssstem des Fahrzeugs übernimmt und vorzugsweise mit Hilfe der Steuer- und/oder Regelungseinrichtung eine Wankrate des Fahrzeugs ermittelt wird, sind die einleitend erwähnten Probleme eliminierbar und eine kompakte elektrische Servolenkung angegeben, deren Betrieb auch im Zusammenspiel von mehreren Steuergeräten oder Fahrdynamikreglern stabil ist. Dabei ist es zweckmäßig, dass Stabilitätsindikatoren für die Servolenkung und Fahrdynamikregler oder Steuergeräte erstellt und miteinander verglichen werden, wobei im Fall einer unzulässig hohen Abweichung ein Eingriff in die Reglerstruktur durchgeführt wird.Thereby that a single control and / or regulating device, the control at least one servomotor for providing a steering assist force and an electric actuator and / or its controller for a roll stabilization point of the vehicle and preferably by means of the control and / or regulating device a rolling rate of the vehicle is determined, are the introductory mentioned problems eliminated and a compact electrical Power steering specified, their operation also in the interaction of several control units or vehicle dynamics control is stable. there it is appropriate that stability indicators for the power steering and driving dynamics controller or control units be created and compared with each other, in the case of impermissibly high deviation an intervention in the controller structure is carried out.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
Auf Grundlage des ermittelten Wankwinkels und/oder der Wankrate kann es zweckmäßig sein, weitere Stabilitätsmaßnahmen auf Fahrzeugstabilisierungssysteme, wie etwa auf Überlagerungsmittel zur Lenkwinkelverstellung des Fahrerlenkwinkels zu ergreifen. Mit Hilfe von Überlagerungsmitteln ist es möglich, einen an einer Lenkhandhabe vorgegebenen Lenkradwinkel zur Erhöhung der Fahrstabilität bzw. des Komforts mit einem Zusatzwinkel zu überlagern, so dass sich fahrdynamikabhängig bzw. komfortabhängig ein varialbles Übersetzungsverhältnis zwischen Lenkradwinkel und mittlerem Radlenkwinkel der lenkbaren Räder des Fahrzeugs einstellt. Dadurch ist es sicherheitstechnisch z. B. möglich, ein Kraftfahrzeug, welches auszubrechen droht, durch eine entsprechende Korrektur des Radlenkwinkels wieder in eine stabile Fahrsituation zurückzuführen. Die Überlagerungsmittel können auch andere Fahrdynamiksysteme, wie z. B. ein elektronisches Stabilitätsprogramm (ESP) oder ein Antiblockiersystem (ABS) mitunterstützen.On Basis of the determined roll angle and / or the roll rate can it may be appropriate to take further stability measures on vehicle stabilization systems, such as overlay means for To take steering angle adjustment of the driver's steering angle. With help of overlaying agents it is possible to use one on a steering handle predetermined steering wheel angle to increase the driving stability or the comfort with an additional angle to superimpose, so depending on driving dynamics or depending on the comfort a varialbles ratio between Steering wheel angle and middle wheel steering angle of the steerable wheels of the vehicle. As a result, it is safety z. B. possible, a motor vehicle, which threatens to break out, by a corresponding correction of the wheel steering angle back in attributed a stable driving situation. The overlay means can also other vehicle dynamics systems, such. B. an electronic Stability Program (ESP) or Anti-lock Braking System (ABS) sometimes support.
Komforttechnisch ist es auch möglich, einen Lenkradwinkel beispielsweise einen geschwindigkeitsabhängigen Zusatzwinkel zu überlagern. Dadurch kann bei niedriger Fahrgeschwindigkeit ein relativ hohes Übersetzungsverhältnis eingestellt werden, d. h. eine relativ kleine Drehung an einer Lenkhandhabe führt zu einem relativ großen Lenkwinkel der Räder des Fahrzeugs. Bei hohen Fahrgeschwindigkeiten kann dagegen ein relativ großes Übersetzungsverhältnis (gegenüber der mechanischen Grundübersetzung indirektes Übersetzungsverhältnis) eingestellt werden damit sich die Fahrstabilität des Kraftfahrzeugs erhöht.Comfort technology, it is also possible to superimpose a steering wheel angle, for example, a speed-dependent additional angle. As a result, a relatively high gear ratio can be set at low vehicle speed, ie a relatively small rotation on a steering handle leads to a relatively large steering angle of the wheels of the vehicle. At high driving speed On the other hand, a relatively large transmission ratio (relative to the basic mechanical transmission ratio) can be set to increase the driving stability of the motor vehicle.
Es kann zweckmäßig sein, ein blockiergeschütztes Bremssystem, insbesondere Aktuatoren oder ein Steuergerät dessen durch die Steuer- und/oder Regelungseinrichtung anzusteuern.It may be appropriate, an anti-lock Brake system, in particular actuators or a control unit to control this by the control and / or regulating device.
Für moderne Antriebsstränge (z. B. Allradantriebsstränge) sind so genannte „Active-Yaw”- oder „Torque-Vectoring”-Systeme bekannt. Mit solch einem System wird die Giergeschwindigkeit eines Fahrzeugs aktiv gesteuert, wobei die Antriebsmomente ungleich auf die Räder verteilt werden können. Dadurch kann mehr Antriebsmoment beispielsweise zum kurvenäußeren Rad gelenkt werden, sodass bei normalen Fahrbedingungen ein übersteuerndes Verhalten eingestellt werden kann. Solche Systeme weisen beispielsweise eine Differentialeinheit mit einem Differentialgehäuse, das ein Ausgleichsgetriebe und Getriebe beinhaltet auf. Jedes der Getriebe weist eine Lamellenkupplung mit einem Aktuator und einer Getriebeanordnung auf. Eine Antriebswelle, die drehfest mit einer Kardanwelle des Fahrzeugs verbunden ist, ist in dem Differentialgehäuse drehbar gelagert. Zudem sind Abtriebswellen, die drehfest mit den Achswellen verbunden sind, in dem Differentialgehäuse drehbar gelagert.For modern drive trains (eg four-wheel drive trains) are so-called "active-yaw" or "torque-vectoring" systems known. With such a system, the yaw rate of a vehicle becomes actively controlled, with the drive torque unequal to the wheels can be distributed. This allows more drive torque For example, be directed to the outside wheel, so in normal driving conditions an oversteer Behavior can be adjusted. Such systems are for example a differential unit with a differential housing, which includes a differential and gearbox on. Each of the Transmission has a multi-plate clutch with an actuator and a gear assembly on. A drive shaft that is non - rotatable with a cardan shaft of the Vehicle is connected in the differential case rotatably mounted. In addition, output shafts are non-rotatable with the axle shafts are connected, rotatably mounted in the differential housing.
Mit Hilfe wenigsten einer Lameellenkupplung kann ein zusätzliches Drehmoment auf eine der beiden Abtriebswellen übertragen werden um die Antriebsmomente ungleich auf die Räder zu verteilen.With Help at least a lameel clutch can be an additional Transfer torque to one of the two output shafts Be equal to the drive torque unequal to the wheels to distribute.
Ein Steuergerät für ein derartiges „Torque-Vectoring”-System und/oder ein oder mehrere Aktuatoren eines solchen Systems lassen sich über die Steuer- und/oder Regelungseinrichtung ansteuern.One Control unit for such a "torque vectoring" system and / or leave one or more actuators of such a system to control via the control and / or regulating device.
Alle Steuergeräte und Aktuatoren oder Servomotoren der elektrischen Servolenkung lassen sich über die Steuer- und/oder Regelungseinrichtung mit Hilfe einer bidirektionalen Busverbindung ansteuern. Kommunikationsparameter der bidirektionalen Kommunikation können hierbei ein Lenkwinkel und/oder die Fahrgeschwindigkeit des Fahrzeug sein. In Abhängigkeit von der Anzahl der in dem Fahrzeug vorgesehenen Stabilitätsprogramme können mehrere Kommunikationsparameter wie eine Gierrate und/oder ein Drehmoment an einem Wankstabilisator und/oder ein Drehwinkel an einem Wankstabilisator und/oder eine Radeinfederposition des Fahrwerks des Fahrzeugs und/oder die Stromaufnahme von Aktuatoren der Stabilitätsprogramme bilden.All Control devices and actuators or servomotors of electrical Power steering can be via the control and / or regulating device with Activate help of a bidirectional bus connection. communication parameters The bidirectional communication can be a steering angle and / or be the driving speed of the vehicle. Dependent on from the number of stability programs provided in the vehicle can have multiple communication parameters such as a yaw rate and / or a torque on a roll stabilizer and / or a rotation angle on a roll stabilizer and / or a Radeinfederposition of the chassis of the vehicle and / or the current consumption of actuators of the stability programs form.
Es kann zweckmäßig sein, die Schaltungsträger der Steuer- und/oder Regelungseinrichtung und der Steuergeräte als Leiterplatte zu bilden. Die im Bereich insbesondere von Leistungsendstufen aufgrund der hohen Ströme und Verlustleistungen herrschenden Bedingungen lassen es jedoch sinnvoll erscheinen, die Schaltungsträger als Metall-Keramik-Hybridsubstarte bevorzugt in Sandwichbauweise mit einer Keramikplatte und Metallbeschichtungen auszubilden.It may be appropriate, the circuit carrier the control and / or regulating device and the control devices to form as a circuit board. The in particular of power output stages due to the high currents and power loss conditions However, it makes sense, the circuit carrier as a metal-ceramic hybrid substrate preferably in sandwich construction with a ceramic plate and metal coatings form.
Als Servomotoren eignen sich Synchron- oder Asynchronmaschinen. Es können grundsätzlich mehrere Aktuatoren oder Servomotoren von der Steuer- und/oder Regelungseinrichtung angesteuert sein.When Servo motors are suitable for synchronous or asynchronous machines. It can basically several actuators or servomotors of be controlled by the control and / or regulating device.
