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 Beispiel.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 another example.
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 Servolenkung deren Betrieb auch im Zusammenspiel von mehreren Fahrdynamikreglern stabil ist, anzugeben.Of the Invention is based on the object, a compact power steering their operation also stable in the interaction of several vehicle dynamics controllers is to indicate.
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 Aktuators zur Lenkwinkelüberlagerung des Fahrerlenkwinkels durchführt, wobei es zweckmäßig ist, dass Stabilitätsindikatoren für die Servolenkung und Fahrdynamikregler erstellt und miteinander verglichen werden, wobei im Fall einer unzulässig hohen Abweichung ein Eingriff in die Reglerstruktur durchgeführt wird, ist eine kompakte und im Betrieb stabil arbeitende Servolenkung angegeben.Thereby that a single control and / or regulating device, the control at least one servomotor for providing a steering assist force and an actuator for steering angle superposition of the driver steering angle where appropriate, that stability indicators for the power steering and vehicle dynamics controllers are created and compared with each other, whereby in the case of an impermissibly high deviation an intervention is performed in the controller structure is a compact and stably operating power steering indicated in the operation.
Bevorzugte Ausführungen ergeben sich aus den Unteransprüchen.preferred Designs emerge from the dependent claims.
Es kann zweckmäßig sein, die Steuer- und/oder Regelungseinrichtung an einem Überlagerungsgetriebe oder einem Servomotor für das Überlagerungsgetriebe der Servolenkung anzuordnen.It may be appropriate, the control and / or regulating device at a superposition gear or a servomotor for to arrange the superposition gearbox of the power steering.
Es kann auch zweckmäßig sein, die Steuer- und/oder Regelungseinrichtung an einem Aktuator zur Lenkwinkelüberlagerung des Fahrerlenkwinkels anzuordnen oder an oder in einem, das Lenkgetriebegehäuse bildenden Gestell anzuordnen. Die Servolenkung ist bevorzugt als elektrische Hilfskraftlenkung ausgebildet.It may also be appropriate to the tax and / or Control device on an actuator for steering angle superposition to arrange the driver's steering angle or on or in one, the steering gear housing to arrange forming frame. The power steering is preferred as electric power steering system formed.
Die Erfindung wird nun näher anhand eines Ausführungsbeispiels beschrieben und anhand der beiliegenden Zeichnung wiedergegeben.The Invention will now be closer with reference to an embodiment described and reproduced with reference to the accompanying drawings.
