Abstract
Description
Die Erfindung betrifft ein System zur Ermittlung des vom Fahrer eines Fahrzeugs mit einem Lenkrad vorgegebenen Lenkwinkels in einer Fahrzeug-Lenkanlage, in der der Fahrer-Lenkwunsch auf hydraulischem und/oder elektronischem Weg an einen die lenkbaren Fahrzeug-Räder bewegenden Aktuator übermittelt wird, wobei an das Lenkrad mittels eines einen Motorlagesensor mit mehreren Magnetpol-Paaren aufweisenden Elektromotors unter Zwischenschaltung eines Untersetzungsgetriebes ein Drehmoment anlegbar ist, und wobei das vom Fahrer an das Lenkrad angelegte Drehmoment mittels einer Torsionsstab-Messvorrichtung messbar ist. Zum Stand der Technik wird neben der
Eine Fahrzeug-Lenkanlage, in der viele dieser genannten Merkmale gezeigt sind und bei der ebenso wie bei einer erfindungsgemäßen Lenkanlage keine mechanische Verbindung zwischen dem Lenkrad des Fahrers und einem die lenkbaren Fahrzeug-Räder verschwenkenden Lenk-Getriebe vorgesehen ist, ist in der erstgenannten
In der
Vorliegend soll nun für eine Fahrzeug-Lenkanlage mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen ein System zur Ermittlung des vom Fahrer vorgegebenen Lenkwinkels aufgezeigt werden, welches keinen eigenständigen Lenkwinkelsensor am Lenkrad bzw. an der mit diesem drehfest verbundenen Lenksäule benötigt (= Aufgabe der vorliegenden Erfindung).In the present case, for a vehicle steering system with the features specified in the preamble of
Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass der vom Fahrer vorgegebene Lenkwinkel multiturnfähig aus dem Signal des Motorlagesensors des (im Oberbegriff des unabhängigen Patentanspruchs genannten) Elektromotors und einer an der Torsionsstab-Messvorrichtung vorgesehenen, ebenfalls mehrere Magnetpol-Paare aufweisenden Winkelmessvorrichtung unter Anwendung des Noniusprinzips ermittelt wird, wobei die Zahl der Magnetpol-Paare des Motorlagesensors sowie der Winkelmessvorrichtung an der Torsionsstab-Messvorrichtung und weiterhin das Übersetzungsverhältnis des Untersetzungsgetriebes solchermaßen gewählt ist oder sind, dass ein Lenkrad-Drehwinkelbereich zumindest in der Größenordnung von 1440° abgedeckt ist.The solution to this problem is characterized in that the predetermined by the driver steering angle multiturnfähig from the signal of the motor position sensor of the (referred to in the preamble of the independent claim) electric motor and provided on the torsion bar measuring device, also having a plurality of magnetic pole pairs angle measuring device using the vernier principle is determined, wherein the number of magnetic pole pairs of the motor position sensor and the angle measuring device on the Torsionsstab-measuring device and further the transmission ratio of the reduction gear is selected such or are that a steering wheel rotation angle range is covered at least in the order of 1440 °.
