Ziel der Erfindung ist es, eine verbesserte Anordnung zur Bremsbelagverschleißanzeige bei einem Kraftfahrzeug bereitzustellen, welche eine genauere Vorhersage des Belagverschleißes ermöglicht.aim The invention is an improved arrangement for brake pad wear indicator in a motor vehicle providing a more accurate prediction the lining wear allows.
Diese Aufgabe wird erfindungsgemäß durch die Anordnung nach Anspruch 1 gelöst.These The object is achieved by the Arrangement according to claim 1 solved.
Der Erfindung liegt der Gedanke zugrunde, zumindest zwei der an einem Kraftfahrzeug angeordneten Bremsbelagverschleißsensoren in unterschiedlichen Tiefen innerhalb verschiedener Bremsbeläge anzubringen. Hierdurch ergeben sich unterschiedliche Bremsbelagstärken bis zum Ansprechen der beiden Verschleißsensoren. Dies ist vorteilhaft, um den weiteren Bremsbelagverschleiß vorherzusagen. Außerdem kann damit eine Verschleißanzeige an den Fahrer bzw. für die Werkstatt optimiert werden. Dabei wird von der Annahme ausgegangen, dass der Bremsbelagverschleiß an den Bremsbelägen im Wesentlichen gleich groß ist.Of the Invention is based on the idea, at least two of the one Motor vehicle arranged brake pad wear sensors in different To install depths within different brake pads. This results different brake pad thicknesses to the response of both wear sensors. This is advantageous to predict the further brake pad wear. Furthermore can thus wear a wear indicator the driver or for the workshop can be optimized. It is assumed that the brake pad wear on the brake pads is essentially the same size.
Dabei ist es vorteilhaft, wenn die beiden in unterschiedlicher Tiefe angebrachten Bremsbelagverschleißsensoren an verschiedenen Rädern angeordnet sind.there It is advantageous if the two are mounted at different depths Brake pad wear sensors on different wheels are arranged.
In einer Weiterbildung der Erfindung werden die beiden in unterschiedlicher Tiefe angebrachten Bremsbelagverschleißsensoren an den beiden Rädern einer Achse angeordnet. Dies ist vorteilhaft, da davon ausgegangen werden kann, dass der Bremsbelagverschleiß auf den Rädern einer Achse im Wesentlichen gleich groß ist.In a development of the invention, the two in different Deep mounted brake pad wear sensors on the two wheels of a Axis arranged. This is advantageous because it is assumed may be that the brake pad wear on the wheels of an axle substantially is the same size.
In einer weiteren bevorzugten Ausführungsform sind an jeder Achse des Fahrzeuges zwei in unterschiedlicher Tiefe angebrachte Bremsbelagverschleißsensoren angeordnet. Hierdurch wird auf jeder Achse eine Art Zweistufigkeit erreicht.In a further preferred embodiment are on each axis of the vehicle two at different depths attached brake pad wear sensors arranged. This makes a kind of two-stage on each axis reached.
Dabei ist es bevorzugt, dass die Tiefen der jeweils tiefer oder höher angebrachten Bremsbelagverschleißsensoren an allen Achsen gleich sind. Hierdurch wird eine gemeinsame Weiterverarbeitung/Auswertung der Bremsbelagverschleißsignale der in gleicher Tiefe angeordneten Bremsbelagverschleißsensoren, z.B. durch in Reihe Schaltung der Bremsbelagverschleißsensoren, möglich.there It is preferred that the depths of each lower or higher attached Brake pad wear sensors are the same on all axes. This will be a common further processing / evaluation the brake lining wear signals the in the same depth arranged brake pad wear sensors, e.g. by serially switching the brake pad wear sensors, possible.
Es ist bevorzugt, dass die in gleicher Tiefe angebrachten Bremsbelagverschleißsensoren jeweils in der Fahrzeugdiagonale angeordnet sind. Dies ist vorteilhaft, da die hydraulischen Bremskreise üblicherweise diagonal angeordnet sind. So ergibt sich eine ähnliche Abnutzung der Bremsbeläge in der Fahrzeugdiagonale.It it is preferred that the brake pad wear sensors mounted at the same depth are each arranged in the vehicle diagonal. This is advantageous since the hydraulic brake circuits are usually arranged diagonally are. This results in a similar Wear of brake pads in the vehicle diagonal.
Es ist jedoch auch bevorzugt, dass die in gleicher Tiefe angebrachten Bremsbelagverschleißsensoren auf der gleichen Fahrzeugseite angeordnet sind. Hierdurch wird die Verlegung der zu den Bremsbelagverschleißsensoren gehörigen Kabel vereinfacht und es kann Kabelmaterial eingespart werden.It However, it is also preferred that the attached at the same depth Brake pad wear sensors are arranged on the same side of the vehicle. This will be the Laying cables belonging to brake pad wear sensors simplified and it can be saved cable material.
In einer weiteren bevorzugten Ausführungsform wird mindestens ein Signal eines Bremsbelagverschleißsensors in den Zusatzeingang mindestens eines Raddrehzahlsensorelementes ein gespeist. Besonders bevorzugt wird das Signal in den digitalen Zusatzeingang eines Raddrehzahlsensorelementes eingespeist.In a further preferred embodiment At least one brake pad wear sensor signal is generated in the additional input of at least one wheel speed sensor element a fed. The signal is particularly preferred in the digital additional input a wheel speed sensor element fed.
Ebenso ist es bevorzugt, dass jedes Bremsbelagverschleißsignal in den Zusatzeingang eines Raddrehzahlsensorelementes eingespeist wird. Dabei besitzt besonders bevorzugt jedes Raddrehzahlsensorelement einen digitalen Zusatzeingang, in welchen das Bremsbelagverschleißsignal eingespeist wird.As well it is preferred that each brake pad wear signal in the auxiliary input a wheel speed sensor element is fed. It owns particularly preferably, each wheel speed sensor element is a digital one Additional input, in which the brake pad wear signal is fed.
In einer Weiterbildung der Erfindung werden die, insbesondere zwei, Bremsbelagverschleißsensoren, welche in gleicher Tiefe angeordnet sind, in Reihe geschaltet und das Signal in den Zusatzeingang eines Raddrehzahlsensorelementes eingespeist. Auch hier ist der Zusatzeingang des Raddrehzahlsensorelementes besonders bevorzugt ein digitaler Eingang. Ganz besonders bevorzugt sind die beiden Bremsbelagverschleißsensoren, welche in gleicher Tiefe angeordnet sind, in einer Fahrzeugdiagonale angeordnet.In a further development of the invention, the, in particular two, brake pad wear sensors, which are arranged at the same depth, are connected in series and the signal is fed into the auxiliary input of a wheel speed sensor element. Again, the additional input of the wheel speed sensor element is particularly preferably a digital input. Especially preferred are the two brake lining wear sensors, which in are arranged the same depth, arranged in a vehicle diagonal.
Ein Vorteil der erfindungsgemäßen Anordnung ist es, dass für jede Achse eine zweistufige Bremsbelagverscheißerkennung realisiert wird, wobei nur einstufige, und damit kostengünstige, Bremsbelagverschleißsensoren verwendet werden. Ein weiterer Vorteil der erfindungsgemäßen Anordnung liegt darin, dass sich bei Verwendung von Raddrehzahlsensoren mit Zusatzprotokoll eine Einsparung an Kabelmaterial und Verlegungsaufwand für den Automobilhersteller ergibt. Üblicherweise werden die Signale der Raddrehzahlsensoren und der Bremsbelagverschleißsensoren getrennt, z.B. parallel, zum Steuerge rät geführt. Durch die Anbindung eines Bremsbelagverschleißsensors an einen Raddrehzahlsensor verkürzt sich die Leitung des Bremsbelagverschleißsensors erheblich.One Advantage of the arrangement according to the invention is that for each axle realizes a two-stage brake pad detection, whereby only single-stage, and thus cost, brake pad wear sensors be used. Another advantage of the inventive arrangement is in that when using wheel speed sensors with additional protocol a saving in cable material and installation costs for the car manufacturer results. Usually become the signals of the wheel speed sensors and brake pad wear sensors separated, e.g. parallel, led to Steuerge. By connecting a Brake pad wear sensor shortened to a wheel speed sensor The line of the brake pad wear sensor considerably.
Weitere bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung anhand von Figuren.Further preferred embodiments emerge from the dependent claims and the description below with reference to figures.
