Der Erfindung liegt die Aufgabe zugrunde, eine zuverlässige und multifunktionale Türgriffanordnung zur Verfügung zu stellen, welche in robuster und verlässlicher Weise Betätigungen erfasst.  The invention has for its object to provide a reliable and multifunctional door handle assembly available, which detects operations in a robust and reliable manner.
Diese Aufgabe wird durch eine Türgriffanordnung gemäß  This object is achieved by a door handle assembly according to

Gemäß der Erfindung wird die Türgriffhandhabe mit einem Kopplungselement an das Fahrzeug, insbesondere an die  According to the invention, the door handle handle with a coupling element to the vehicle, in particular to the
fahrzeugseitige Schließeinrichtung oder den fahrzeugseitigen Griffträger gekoppelt. Bei herkömmlichen Türgriffen ist derVehicle-side locking device or the vehicle-side handle support coupled. In conventional door handles is the
Griff zwar ggf. mehrteilig ausgebildet, die Griffkomponenten der Handhabe mit Kopplungsmitteln zur Anbringung an dem Fahrzeug sind jedoch meist starr miteinander gekoppelt oder auch gänzlich integral ausgebildet. Gemäß der Erfindung ist das Handle may be formed in several parts, but the handle components of the handle with coupling means for attachment to the vehicle are usually rigidly coupled or even formed integrally. This is according to the invention
Kopplungselement, welches die Handhabe selbst mit dem Fahrzeug in Wirkverbindung setzt, gegenüber der Handhabe beweglich ausgebildet. Bezüglich der Beweglichkeit ist dabei auch eine geringfügige Beweglichkeit umfasst, jedenfalls sind die beiden Elemente nicht integral ausgebildet und in geringem Umfang gegeneinander verschiebbar, verdrehbar oder schwenkbar. Zwischen dem Kopplungselement und der Handhabe ist wenigstens ein Piezo-Sensor angeordnet. Bei Bewegung der Coupling element which sets the handle itself in operative connection with the vehicle, designed to be movable relative to the handle. With regard to the mobility is also a slight mobility includes, in any case, the two elements are not integrally formed and to a small extent mutually displaceable, rotatable or pivotable. At least one piezoelectric sensor is arranged between the coupling element and the handle. When moving the
Elemente gegeneinander wird eine Kraft auf den Sensor ausgeübt, welche detektierbar ist. Es ist also ein Raum zwischen beiden Komponenten vorgesehen, in welchem der Sensor platziert ist. In Abhängigkeit von der Kraft, mit welcher die Handhabe und das Kopplungselement auf den zwischenliegenden Sensor einwirken, generiert der Sensor eine Piezo-Spannung . Elements against each other a force is exerted on the sensor, which is detectable. Thus, a space is provided between both components in which the sensor is placed. Depending on the force with which the handle and the coupling element act on the intermediate sensor, the sensor generates a piezo voltage.
Die Erfindung hat zunächst den Vorteil, dass der Sensor an einer verdeckten Stelle im Fahrzeugtürgriff angeordnet sein kann, ohne dass ein Zugang von außen erforderlich wäre.  The invention initially has the advantage that the sensor can be arranged at a hidden point in the vehicle door handle, without requiring access from the outside.
Herkömmliche Sensorerfassungen mit Piezo-Sensoren verlassen sich oft auf eine unmittelbare Betätigung des Sensors. Weiterhin ermöglich die bewegliche Kopplung der beiden Komponenten Conventional sensor detections with piezo sensors often rely on an immediate operation of the sensor. Furthermore, allows the movable coupling of the two components

Verringerung als auch eine Erhöhung der Krafteinwirkung auf den Sensor detektierbar sind, wie weiter unten beschrieben wird. Reduction and an increase in the force on the sensor are detectable, as will be described below.
Die Art der Bewegung, die zur Betätigung des Sensors führt, kann vielfältig sein. Vorzugsweise sind sowohl an der Handhabe als auch in dem Kopplungsmittel jeweils Kontaktflächen  The type of movement that leads to the operation of the sensor can be varied. Preferably, both on the handle and in the coupling means each contact surfaces

In einer besonders bevorzugten Gestaltung sind  In a particularly preferred design
Kopplungsmittel und Handhabe gegeneinander in Richtung einer Ruhestellung vorgespannt. Diese Vorspannung kann durch ein elastisches Element, beispielsweise ein elastische Material oder ein Federelement erreich werden. Kopplungselement und Handhabe können durch diese Vorspannung in eine mechanisch kompakt anmutende Einheit gekoppelt werden, die entgegen der Vorspannung jedoch weiterhin Bewegungen von der Handhabe gegenüber dem Coupling means and handle biased towards each other in the direction of a rest position. This bias can be achieved by an elastic element, such as an elastic material or a spring element. Coupling element and handle can be coupled by this bias in a mechanically compact-looking unit, however, the movements of the handle against the

In der Ruhestellung kann dabei das Piezo-Element derart zwischen Handhabe und Kopplungselement platziert sein, dass es durch die Vorspannung in Anlage zu beiden der Elemente gebracht wird. Eine Kraftausübung auf die Handhabe, kann dann einerseits zur einer erhöhten Belastung des Piezo-Elementes führen, wenn sie in dieselbe Richtung wirkt wie die Vorspannung, oder zu einer Entlastung entgegen der Vorspannungsrichtung. Auf diese Weise ist eine weitere verbesserte Benut zbarkeit gewährleistet, denn sowohl ein Eindrücken gegen den Türgriff ist detektierbar als auch ein Ziehen am Türgriff. Da der Piezo in seiner Ruhelage bereits durch die Vorspannungsmittelkraft beaufschlagt ist, wirkt eine Kraftwegnahme, also eine Verminderung der Vorspannung ebenso eine Signaländerung wie eine Krafterhöhung durch weitere Kompression des Piezos. Ein und derselbe Piezo-Kristall kann auf diese Weise sowohl für einen Öffnungsvorgang der Tür verwendet werden, also auch für einen Verriegelungsvorgang, wenn In the rest position, the piezoelectric element can be placed between the handle and the coupling element in such a way that it is brought into contact with both of the elements by the bias. A force exerted on the handle, then on the one hand lead to increased stress on the piezoelectric element, if it acts in the same direction as the bias, or to a relief against the bias direction. In this way, a further improved usability is ensured, because both a push against the door handle is detectable as well as a pull on the door handle. Since the piezo is already acted upon in its rest position by the biasing force, a force removal, so a reduction in the bias voltage as well as a signal change as an increase in force by further compression of the piezo. One and the same piezo crystal can be used in this way both for an opening operation of the door, and thus also for a locking operation, if

Die Figuren 2a und 2b zeigen in schematischer Darstellung die erfindungsgemäßen Komponenten des Türgriffs.  Figures 2a and 2b show a schematic representation of the components of the door handle according to the invention.
In Figur la ist eine Außenansicht eines Fahrzeugtürgriffs 1 gezeigt, der an einer Fahrzeugtür 2 angeordnet ist. An der  In FIG. 1 a, an exterior view of a vehicle door handle 1 is shown, which is arranged on a vehicle door 2. At the
Außenseite der Fahrzeugtür ist die Handhabe 3 sichtbar, die eine Griffmulde 4 an der Fahrzeugtür 2 überspannt. Ein Benutzer erlangt Zugriff auf die Handhabe 3, um die Schlossbetätigung vorzunehmen . Outside the vehicle door, the handle 3 is visible, which spans a grip 4 on the vehicle door 2. A user gains access to the handle 3 to perform the lock operation.
In Figur lb ist das Türblech 2 aus Figur la entfernt und eine vergrößerte Darstellung so gewählt, dass neben der Handhabe 3 auch der auf der Innenseite der Tür, hinter dem Blech 2 liegende Griffträger 5 erkennbar ist. Der Griffträger 5 nimmt mechanische Komponenten auf und stellt sowohl ein Lager als auch eine Kopplung mit den weiteren Schlosskomponenten in der Tür zur Verfügung. Es ist ersichtlich, dass der Türgriff 1 in den  In Figure lb, the door panel 2 is removed from Figure la and an enlarged view is chosen so that in addition to the handle 3 and on the inside of the door, behind the sheet 2 lying grip carrier 5 can be seen. The handle support 5 receives mechanical components and provides both a bearing and a coupling with the other lock components in the door. It can be seen that the door handle 1 in the
Endbereichen der Handhabe 3 eine Kopplung zwischen Handhabe 3 und Griffträger 5 aufweist, wobei Endstücke des außenliegenden Griffs durch das Türblech 2 in dem Griffträger 5 hineinragen. End portions of the handle 3, a coupling between the handle 3rd and handle carrier 5, wherein end pieces of the outer handle protrude through the door panel 2 in the handle support 5.
Die Handhabe 3 ist isoliert vom Griffträger 5 in Figur lc gezeigt, wobei die Endabschnitte 10 und 11 dargestellt sind, welche Kopplungsmittel der Handhabe 3 mit der fahrzeugseitigen Griffträgeranordnung 5 darstellen. Erfindungsgemäß sind in diesem Ausführungsbeispiel die Kopplungsmittel 11 und die  The handle 3 is shown isolated from the handle support 5 in Figure lc, wherein the end portions 10 and 11 are shown, which constitute coupling means of the handle 3 with the vehicle-side handle support assembly 5.

In dem Handle 3 and coupling means 11. In this embodiment, the coupling means 11 is formed as a hook-like approach, which is guided into the body of the handle 3. By doing
Körper der Handhabe 3 ist eine Ausnehmung 15 derart angeordnet, dass ein geringer Bewegungsspielraum für das Kopplungsmittel 11 gegen die Handhabe 3 möglich ist. Spannmittel 16 drängen das Kopplungsmittel 11 in eine Ruhelage gegenüber der Handhabe 3. Zwischen der Hantdhabe 3 und dem Kopplungsmittel 11 ist ein Piezo-Sensor 20 angeordnet, der mit einer Auswerteschaltung 21 elektrisch gekoppelt ist. Bei einem Zug an der Handhabe, z. B. zum Öffnen der Tür, wirkt eine Kraft in Pfeilrichtung 25 auf die Handhabe. Die im Fahrzeug inneren angekoppelten Kopplungsmittel 11 komprimieren daraufhin den Piezo-Sensor 20 und rufen dort eine Spannung hervor, die in der Auswerteschaltung 21 erfassbar ist . Body of the handle 3 is a recess 15 arranged such that a small range of motion for the coupling means 11 against the handle 3 is possible. Clamping means 16 urge the coupling means 11 in a rest position relative to the handle 3. Between the Hantdhabe 3 and the coupling means 11, a piezoelectric sensor 20 is arranged, which is electrically coupled to an evaluation circuit 21. In a train on the handle, z. B. to open the door, a force in the direction of arrow 25 acts on the handle. The coupled inside the vehicle coupling means 11 then compress the piezoelectric sensor 20 and call there a voltage that can be detected in the evaluation circuit 21.
Wird hingegen, wie in Figur 2b, eine Kraft in Pfeilrichtung 26 auf die Handhabe 3 ausgeübt, wird das Kopplungsmittel 11 von dem Piezo-Sensor 20 entlastet oder sogar leicht abgehoben, wobei die Kraft der elastischen Vorspannmittel 16 zu überwinden ist. Auch diese Kraftentlastung führt zu einem Spannungssignal, was in der Auswerteschaltung 21 erfassbar ist. Die Auswerteschaltung 21 ist mit einer fahrzeugseitigen Steuereinrichtung gekoppelt, um Betätigungssignale an diese Steuereinrichtung zu übermitteln. Diese Steuereinrichtung löst dann die zugehörigen If, on the other hand, as in FIG. 2b, a force is exerted on the handle 3 in the direction of arrow 26, the coupling means 11 is relieved or even slightly lifted by the piezoelectric sensor 20, the force of the elastic biasing means 16 having to be overcome. This power relief leads to a voltage signal, which can be detected in the evaluation circuit 21. The evaluation circuit 21 is coupled to a vehicle-side control device in order to transmit actuating signals to this control device. This controller then triggers the associated
