Abstract
Description
Die Erfindung betrifft einen Kraftfahrzeugtürgriff mit einer Sensorelektrode eines kapazitiven Annäherungssensors, einer mit der Sensorelektrode gekoppelten Steuer- und Auswerteschaltung, eine Masseleitung und wenigstens einer Spannungsversorgungsleitung, die mit der Steuer- und Auswerteschaltung gekoppelt und aus dem Türgriff herausgeführt sind, einer Antennenspule, die in der Nähe der Sensorelektrode angeordnet ist und zum Aussenden langwelliger HF-Signale dient, und wenigstens einer Antennenspulenzuleitung, die neben der Masse- und der Spannungsversorgungsleitung aus dem Türgriff herausgeführt ist.The The invention relates to a motor vehicle door handle with a sensor electrode a capacitive proximity sensor, a control and evaluation circuit coupled to the sensor electrode, a ground line and at least one power supply line, which is coupled to the control and evaluation circuit and from the door handle led out are, an antenna coil, which are arranged in the vicinity of the sensor electrode is and for transmitting long-wave RF signals, and at least an antenna coil lead, in addition to the ground and the power supply line led out of the door handle.
Ein Türgriff der eingangs genannten Art wird in Kraftfahrzeugen verwendet, um einem berechtigten Benutzer, der im Besitz eines ID-Gebers ("Schlüssels") für das Kraftfahrzeug ist, einen Zugang zu dem Kraftfahrzeug zu ermöglichen, ohne daß dieser den Schlüssel zu betätigen oder gar in ein Schloß der Tür einzuführen braucht. Eine derartige Zugangsmöglichkeit zu einem Kraftfahrzeug bezeichnet man auch als "Keyless Entry". Mit Hilfe der Sensorelektrode des kapazitiven Annäherungssensors, bei welcher es sich in der Regel um eine an der Innenseite des Türgriffs in dessen Innerem untergebrachte dünne Metallplatte oder Metallschicht handelt, wird ein sich zwischen der Sensorelektrode und der Umgebungsmasse ausbildendes elektrisches Feld erzeugt, welches einer bestimmten Kapazität der Sensorelektrode gegenüber Masse entspricht. Dringt beispielsweise die Hand eines den Zugang wünschenden Benutzers in dieses elektrische Feld ein, so ändert sich das elektrische Feld und somit auch die zwischen der Sensorelektrode und Masse messbare Kapazität. Besonders stark ändert sich die Kapazität, wenn die Hand in den Zwischenraum zwischen der Innenseite des Türgriffs (wo sich die Sensorelektrode befindet) und der me tallischen Türwandung (welche auf Masse liegt) eindringt. Diese relativ starke Änderung der messbaren Kapazität wird mit Hilfe eines Schwellwertvergleichs herangezogen, um ein das Zugreifen des Benutzers anzeigendes Signal zu erzeugen. Die Auswertung des von der Sensorelektrode erzeugten Signals und die Erzeugung des den Zugriff eines Benutzers anzeigenden Signals übernimmt eine Steuer- und Auswerteschaltung. Die Steuer- und Auswerteschaltung, zumindest soweit diese die mit der Sensorelektrode gekoppelten Eingangsschaltungen umfaßt, ist ebenfalls im Türgriff angeordnet, da die Zuleitung zwischen der Sensorelektrode und der Steuer- und Auswerteschaltung ebenfalls als Sensorelektrode wirkt und ein Herausführen dieser Zuleitung aus dem Türgriff zu einer unerwünschten Feldverteilung führen würde.One door handle The type mentioned is used in motor vehicles to an authorized user who possesses an ID transmitter ("key") for the motor vehicle is to allow access to the motor vehicle without this the key to press or even in a castle of Door needs to introduce. Such accessibility A motor vehicle is also called a keyless entry. With the help of the sensor electrode of the capacitive proximity sensor, which is usually one on the inside of the door handle housed in its interior thin metal plate or metal layer is a, between the sensor electrode and the surrounding mass generating electric field generated which a specific Capacity of the Sensor electrode opposite Mass corresponds. Penetrates, for example, the hand of an access wishing User in this electric field, so the electrical changes Field and thus also measurable between the sensor electrode and ground Capacity. Particularly strong changes the capacity, when the hand enters the space between the inside of the door handle (Where the sensor electrode is located) and the me tallischen door wall (which lies on earth) penetrates. This relatively strong change the measurable capacity is used with the help of a threshold comparison to a to generate the signal indicating the user's access. The Evaluation of the signal generated by the sensor electrode and the Generation of the access of a user indicating signal takes over a control and evaluation circuit. The control and evaluation circuit, at least as far as this which comprises the input circuits coupled to the sensor electrode also arranged in the door handle, because the supply line between the sensor electrode and the control and Evaluation circuit also acts as a sensor electrode and a lead out this Supply line from the door handle to an undesirable Lead field distribution would.
Wenn mit Hilfe des kapazitiven Annäherungssensors ein Zugriff eines Benutzers erfaßt wird, so wird bei einem "Keyless Entry"-System ein Dialog zwischen einem Steuergerät des Kraftfahrzeugs und dem bei dem Benutzer befindlichen ID-Geber initiiert. Dabei müssen sowohl Signale vom Kraftfahrzeug an den ID-Geber als auch in umgekehrter Richtung ausgetauscht werden. Da lediglich solche ID-Geber angesprochen werden sollen, die sich in unmittelbarer Nähe der Tür, deren Türgriff betätigt werden soll, befinden, ist es erforderlich, für die Kommunikation vom Kraftfahrzeug zum ID-Geber zumindest anfänglich eine Verteilung eines elektromagnetischen Feldes der Sendeeinrichtung des Kraftfahrzeugs zu erzeugen, die lediglich in unmittelbarer Nähe des Kraftfahrzeugs ausreicht, um eine Empfangseinrichtung des ID-Gebers zum Ansprechen zu veranlassen. Deshalb wählt man – zumindest für den Beginn des Dialogs zwischen der Steuereinrichtung des Kraftfahrzeugs und dem ID-Geber – eine Sendespule, die im langwelligen Hochfrequenzbereich angesteuert wird. Diese Sendespule, beispielsweise eine auf einem Ferritkern aufgewickelte Spule, wird ebenfalls in den Türgriff integriert und erzeugt ein elektromagnetisches Wechselfeld, welches lediglich im Nahbereich (das heißt innerhalb von Entfernungen, die weit unterhalb der Wellenlänge liegen) ausreicht, um ein Ansprechen der Empfangseinrichtung des ID-Gebers zu ermöglichen.If by means of the capacitive proximity sensor a user's access is detected, so in a "keyless entry" system is a dialogue between a control unit of the motor vehicle and the ID transmitter located at the user initiated. It must both signals from the motor vehicle to the ID transmitter and in reverse Direction are exchanged. Since only such ID donors addressed should be located in the immediate vicinity of the door whose door handle is to be operated, it is necessary for the communication from the motor vehicle to the ID transmitter at least initially one Distribution of an electromagnetic field of the transmitting device of the motor vehicle, which only in the immediate vicinity of the motor vehicle sufficient to a receiving device of the ID transmitter to respond to induce. Therefore, choose man - at least for the Beginning of the dialogue between the control device of the motor vehicle and the ID transmitter - one Transmitting coil, which is driven in the long-wave high-frequency range becomes. This transmitter coil, for example one on a ferrite core wound coil, is also integrated and generated in the door handle an alternating electromagnetic field, which only in the vicinity (the is called within distances far below the wavelength), to allow a response of the receiving device of the ID transmitter.
Diese Sendespule ist im Türgriff in der Regel in der Nähe der Sensorelektrode des kapazitiven Annäherungssensors, vorzugsweise langgestreckt parallel zu dieser Elektrode, angeordnet. Die die Sendespule ansteuernden Treiberschaltungen befinden sich in der Regel nicht im Türgriff, sondern in einem innerhalb des Kraftfahrzeugs untergebrachten Steuergerät, so daß Antennenspulenzuleitungen von der Antennenspule aus dem Türgriff herauszuführen sind.These Transmitter coil is in the door handle usually nearby the sensor electrode of the capacitive proximity sensor, preferably elongated parallel to this electrode, arranged. The the Transmitting coil driving driver circuits are located in the Usually not in the door handle, but in a housed within the motor vehicle control unit so that Antennenspulenzuleitungen from the antenna coil from the door handle be led out.
Neben einer Masseleitung und wenigstens einer Spannungsversorgungsleitung, die mit der Steuer- und Auswerteschaltung gekoppelt sind, und den Antennenspulenzuleitungen sind ferner Steuersignalleitungen von der Steuer- und Auswerteschaltung aus dem Türgriff herauszuführen. Es ist auch möglich, daß eine Leitung gleichzeitig sowohl als Antennenspulenzuleitung als auch als Masseleitung oder Spannungsversorgungsleitung genutzt wird.Next a ground line and at least one power supply line, which are coupled to the control and evaluation circuit, and the Antenna coil leads are also control signal lines of to lead the control and evaluation circuit out of the door handle. It is possible, too, that one Lead simultaneously both as antenna coil lead and is used as a ground line or power supply line.
Bei dieser bekannten Anordnung hat es sich nunmehr gezeigt, daß es durch Störsignale auf den Antennenspulenzuleitungen, welche beispielsweise durch kurzzeitige Unterbrechungen der Zuleitungen entstehen können, zu Fehl-Auslösungen des kapazitiven Sensors kommen kann.at this known arrangement, it has now been shown that it is through noise on the Antennenspulenzuleitungen, which for example by short-term Interruptions of the supply lines may result in false trips of the capacitive sensor can come.
Aufgabe der Erfindung ist es, die Gefahr von Fehl-Auslösungen des kapazitiven Sensors zu verringern.task The invention is the risk of false tripping of the capacitive sensor to reduce.
Diese Aufgabe wird bei einem Kraftfahrzeugtürgriff der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß in dem Kraftfahrzeugtürgriff wenigstens ein Kondensator zwischen der wenigstens einen Antennenspulenzuleitung und der Masseleitung und/oder der Spannungsversorgungsleitung eingekoppelt ist, wobei die Kapazität des Kondensators so gewählt ist, daß der Einfluß von Störsignalen auf der wenigstens einen Antennenspulenzuleitung auf die von der Steuer- und Auswerteschaltung erfaßte Kapazität des kapazitiven Annäherungssensors verringert wird, ohne das Senden der langwelligen HF-Signale durch die Antennenspule wesentlich zu beeinträchtigen.These Task is in a motor vehicle door handle of the aforementioned Type according to the invention thereby solved, that in the vehicle door handle at least one capacitor between the at least one antenna coil lead and the ground line and / or the power supply line coupled is, taking the capacity of the capacitor chosen is that the Influence of Noise on the at least one antenna coil lead to that of the control and evaluation circuit detected capacity of the capacitive proximity sensor is reduced without transmitting the long-wave RF signals through significantly affect the antenna coil.
Der Erfindung liegt die Erkenntnis zu Grunde, daß es aufgrund der räumlichen Nähe der Antennenspule zur kapazitiven Sensorelektrode eine starke kapazitive Kopplung zwischen Sensorelektrode und Antennenspule und somit eine kapazitive Kopplung zu den Spulenzuleitungen gibt. Mit Hilfe der geeignet dimensionierten Kondensatoren wird der größte Teil der Störsignale nach Masse abgeleitet, ohne das Senden der langwelligen HF-Signale zu beeinträchtigen.Of the The invention is based on the finding that it is due to the spatial Near the Antenna coil to the capacitive sensor electrode a strong capacitive Coupling between sensor electrode and antenna coil and thus a capacitive coupling to the coil leads are. With the help of suitably dimensioned capacitors will be the largest part the interference signals derived to ground, without transmitting the long-wave RF signals to impair.
Bei der bevorzugten Ausführungsform, bei der zwei Antennenspulenzuleitungen von der Antennenspule aus dem Türgriff herausgeführt sind, wird jeweils ein Kondensator zwischen einem Anschluß in der Nähe der Antennenspule innerhalb des Türgriffs und einem Masseanschluß innerhalb des Türgriffs, mit dem auch die Steuer- und Auswerteschaltung verbunden ist, eingekoppelt. Unter Berücksichtigung des Umstands, daß die übliche Sendefrequenz der Antennenspule im langwelligen Hochfrequenzbereich, beispielsweise bei 125 kHz, liegt, hat sich gezeigt, daß die auftretenden Störimpulse mit Kondensatoren mit einer Kapazität zwischen 10 pF und 1000 pF, vorzugsweise zwischen 20 pF und 200 pF, beispielsweise 50 pF, ausreichend unterdrückt werden können.at the preferred embodiment, at the two antenna coil leads from the antenna coil the door handle led out are each a capacitor between a terminal in the Near the Antenna coil inside the door handle and a ground connection within of the door handle, with which also the control and evaluation circuit is connected, coupled. Taking into account the The fact that the usual transmission frequency the antenna coil in the long-wave high frequency range, for example at 125 kHz, it has been shown that the glitches occurring with capacitors with a capacity between 10 pF and 1000 pF, preferably between 20 pF and 200 pF, for example 50 pF, sufficient repressed can be.
