Abstract

A method is disclosed of allocating transmitters and receiving antennas in tyre-pressure monitoring systems comprising the following elements: a pressure gauge, transmitter and transmitting antenna on each wheel; allocated thereto as appropriate, a receiving antenna on the vehicle body; and a receiving and evaluation electronic system connected to the receiving antenna via cable. An identifier unique to the wheel in question is assigned to each transmitter and the signals are forwarded to the central electronic receiving and evaluation system. The process is characterised by the following process steps: registration of the intensities of the signals originating from the different transmitters and received by the appropriate receiver antennas with their identifiers; comparison of the intensities of signals with different identifiers received by one and the same receiving antenna to ensure that the comparison of intensities is based on a number of consecutively received signals; lastly, selection of the transmitter identifier associated with the greatest intensity at a receiving antenna and assignment thereof to that receiving antenna.

Description

Die Erfindung geht aus von einem Verfahren mit den im Oberbegriff des An­ spruchs 1 angegebenen Merkmalen. Ein solches Verfahren ist aus der WO 93/16891 bekannt. Dort wird eine Kombination aus Druckmeßfühler, Sender und Sendeantenne am Rad mit jeweils zugeordneten Empfangsantennen und einer zentralen Auswerteelektronik an der Karosserie verwendet. Das Problem, das sich bei solchen Reifendrucküberwachungssystemen stellt, ist die eindeutige Zu­ ordnung der Sender zu der jeweiligen Radposition. In der WO 93/16891 wird die­ ses Problem der Positionserkennung wie folgt gelöst: Die Sender erzeugen ein in vier Abschnitte unterteiltes Signal, bestehend aus Präambel, Identifikationssignal, Meßsignal und Postambel. Anhand des Identifikationssignals kann die zentrale Auswerteelektronik die Position erkennen. Dafür muß jedoch zunächst eine Initialisierung durchgeführt werden, in deren Verlauf das jeweilige Identifikations­ signal, verknüpft mit der jeweiligen Position, von der zentralen Auswerteelektronik abgespeichert wird. Um diese Initialisierung durchzuführen, muß das System in einen sogenannten Paarungsmodus geschaltet werden und dann der Reihe nach jeder einzelne Sender einmal aktiviert werden. Danach wird das System wieder in den Meßmodus gebracht, bis sich die Senderpositionen, z. B. bei einem Rad­ wechsel, ändern. Das heißt aber, daß bei jedem Radwechsel eine entsprechend eingewiesene Person diese Initialisierung durchführen muß. Radwechsel in jeder beliebigen Werkstatt oder zu Hause sind dadurch unter Umständen nicht mög­ lich, bzw. nur auf Kosten der Sicherheit. Die einwandfreie Funktion des Systems kann auf Grund möglicher Bedienungsfehler nicht gewährleistet werden.The invention is based on a method with the in the preamble of the pronounced 1 characteristics. Such a method is known from WO 93/16891 known. There is a combination of pressure sensor, transmitter and Transmitting antenna on the wheel with assigned receiving antennas and one central evaluation electronics used on the body. The problem that is the case with such tire pressure monitoring systems order of the transmitters to the respective wheel position. In WO 93/16891 the solved this problem of position detection as follows: The transmitters generate an in four sections divided signal, consisting of preamble, identification signal, Measurement signal and postamble. The central Evaluation electronics recognize the position. For this, however, one must first  Initialization are carried out, in the course of which the respective identification signal, linked to the respective position, from the central evaluation electronics is saved. To carry out this initialization, the system must be in a so-called pairing mode are switched and then in order each individual transmitter can be activated once. Then the system is back in brought the measurement mode until the transmitter positions, z. B. with a wheel change, change. But that means that with every wheel change one accordingly instructed person must carry out this initialization. Wheel change in everyone any workshop or at home may not be possible Lich, or only at the expense of security. The perfect functioning of the system cannot be guaranteed due to possible operating errors.

In der WO 93/08036 wird das Problem umgangen, indem die Informationen der Druckmeßfühler und der daran angeschlossenen Sendeelektronik nicht mit Hilfe einer zentralen Auswerteelektronik an der Karosserie registriert werden, sondern mit Hilfe eines Fernbedienungselementes. Dieses Fernbedienungselement be­ sitzt eine LCD-Anzeigeeinrichtung, die das Ablesen des Reifendruckes ermög­ licht. Will man den Reifendruck ermitteln, so muß man an jedem einzelnen Rad die gewünschte Information mit Hilfe des Fernbedienungselementes abfragen. Dieses Verfahren bietet zwar den Vorteil einer eindeutigen Zuordnung der Meß­ werte, ermöglicht jedoch keine Kontrolle des Reifendrucks während der Fahrt.In WO 93/08036 the problem is avoided by using the information from Pressure sensor and the connected transmitter electronics not with the help central evaluation electronics are registered on the body, but with the help of a remote control element. This remote control element be there is an LCD display that enables the tire pressure to be read light. If you want to determine the tire pressure, you have to do this on every single wheel query the desired information using the remote control element. This method offers the advantage of a clear assignment of the measurement values, but does not allow tire pressure to be checked while driving.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Positionser­ kennung zu entwickeln, welches auch unerfahrenen Mechanikern und Automobil­ besitzern keine besonderen Fähigkeiten abverlangt, wenn es darum geht, nach einem Radwechsel die Zuordnung der Räder zu bestimmten Signalkennungen zu schaffen. Ein Versagen aufgrund möglicher Bedienungsfehler soll ausgeschlos­ sen werden können.The object of the present invention is therefore a method for positioners to develop knowledge which also inexperienced mechanics and automotive possess no special skills when it comes to a wheel change the assignment of the wheels to certain signal identifiers create. Failure due to possible operating errors should be excluded can be sen.

Erfindungsgemäß wird die Aufgabe durch die im Anspruch 1 aufgeführten Merk­ male gelöst. Die zentrale Auswerteelektronik registriert die Intensitäten, mit der derselbe Sender auf jeder Empfangsantenne empfangen wird. Diese Werte wer­ den dann verglichen. Dabei werden mehrere aufeinanderfolgend empfangene Si­ gnale berücksichtigt um fehlerhafte Zuordnungen zu vermeiden. Aus den mehreren Signalen kann z. B. ein Mittelwert gebildet werden, oder man zählt einfach, wie häufig das Ereignis eintritt, daß eine bestimmte Antenne einen Sen­ der, d. h. ein Signal mit einer bestimmten Kennung, am stärksten empfängt (An­ spruch 3). Anschließend wird anhand dem Mittelwerts bzw. anhand der größten Anzahl von Ereignissen die Empfangsantenne dem entsprechenden Sender zu­ geordnet. Da die einem Sender direkt benachbarte Empfangsantenne das Signal in der Regel mit größerer Intensität empfängt, als die anderen Empfangsanten­ nen und zusätzlich noch mehrere Signale zur Auswertung hinzugezogen werden, ist mit diesem Verfahren eine sichere Zuordnung gewährleistet. Und da dieses Verfahren selbsttätig arbeitet, gibt es von vornherein keine Probleme durch Bedienungsfehler.According to the invention, the object is achieved by the items listed in claim 1 times solved. The central evaluation electronics registers the intensities with which  the same transmitter is received on each receiving antenna. Those values who then compared that. In this case, several Si received in succession gnale taken into account to avoid incorrect assignments. From the several signals can e.g. B. an average is formed, or one counts simply how often it happens that a particular antenna detects a sen the, d. H. receives a signal with a specific identifier, strongest (An Proverb 3). Then the average or the largest Number of events the receiving antenna to the corresponding transmitter orderly. Since the receiving antenna directly adjacent to a transmitter receives the signal usually receives with greater intensity than the other recipients and in addition several signals are used for evaluation, a secure assignment is guaranteed with this procedure. And there this Process works automatically, there are no problems from the outset Operating errors.

Eine auf dem gleichen Lösungsprinzip beruhende weitere Lösung der Aufgabe ist im unabhängigen Anspruch 2 angegeben. Dabei sind gegenüber der Lösung nach Anspruch 1 in der Auswertung die Rollen der Empfangsantennen und Sen­ der vertauscht; demgemäß wird beobachtet, welche der verschiedenen Emp­ fangsantennen einen bestimmten Sender, d. h. ein Signal mit bestimmter Ken­ nung, am stärksten empfängt. Auch in diesem Fall werden mehrere aufeinander­ folgende Signale berücksichtigt und ein Mittelwert gebildet oder einfach gezählt, wie oft eine Antenne das Signal mit der ausgewählten Kennung am stärksten empfängt. (Anspruch 3).Another solution to the problem based on the same solution principle is specified in independent claim 2. Are opposite to the solution according to claim 1 in the evaluation of the roles of the receiving antennas and Sen who exchanged; accordingly it is observed which of the various Emp antennas a particular transmitter, d. H. a signal with certain Ken the strongest. In this case too, several will be consecutive the following signals are taken into account and an average is formed or simply counted, how often an antenna produces the strongest signal with the selected identifier receives. (Claim 3).

Eine mögliche Vorgehensweise zum Abspeichern der so erhaltenen Daten in der Auswerteelektronik beschreibt Anspruch 4. Dabei wird eine Zuordnungsmatrix be­ stehend aus allen Senderkennungen und Empfangsantennen gebildet. Der Wert in einer Matrixzelle wird im Verlauf des Zuordnungsverfahrens dann erhöht, wenn für die betreffende Kombination aus Empfangsantenne und Senderkennung die größte Intensität gemessen wird. A possible procedure for storing the data thus obtained in the Evaluation electronics describes claim 4. Here, an assignment matrix is used standing made up of all transmitter identifiers and receiving antennas. The value in a matrix cell is increased in the course of the assignment process if for the relevant combination of receiving antenna and transmitter identification greatest intensity is measured.  

Auf die so beschriebene Art und Weise läßt sich das empfangene Signal auch zur Zuordnung der Senderkennung zu allen Empfangsantennen gleichzeitig nut­ zen. Dazu nutzt man insbesondere die im Anspruch 2 angeführte Vorgehenswei­ se. Dabei werden die Intensitäten der über die verschiedenen Empfangsanten­ nen erhaltenen Signale einer Kennung verglichen und der Wert der Matrixzelle für die Kombination aus Senderkennung und Empfangsantenne mit der größten Intensität erhöht. Nach Empfang mehrerer Signale unterschiedlicher Kennung läßt sich aus der Matrix die Zuordnung für alle Empfangsantennen erstellen. Durch eine ungünstige Radstellung, und damit eine ungünstige Positionierung des Senders in Bezug zur direkt benachbarten Empfangsantenne, könnte das Si­ gnal eines Senders von der direkt benachbarten Empfangsantenne mit geringerer Intensität empfangen werden, als von einer anderen Empfangsantenne. In die­ sem Fall würde in der Matrix der Wert einer falschen Matrixzelle erhöht werden. Um dies zu verhindern, läßt sich mit Vorteil die in Anspruch 5 beschriebene Me­ thode nutzen. Dabei wird außer dem Signal mit der größten Intensität auch das mit der zweitgrößten ermittelt. Liefert die Differenzbildung dieser beiden Werte ei­ nen Wert oberhalb eines bestimmten Grenzwertes, so wird der Wert der Matrix­ zelle, die der größten Intensität angehört, erhöht. Liegt der Wert der Differenz je­ doch unterhalb dieses Grenzwertes, so wird der Meßwert verworfen. Dieser Vor­ gehensweise liegt der Gedanke zugrunde, daß bei ungünstiger Radstellung zwar die Möglichkeit besteht, daß eine andere als die direkt zugeordnete Antenne das Signal mit größter Intensität empfängt daß die Differenz zur zweitgrößten Intensi­ tät in diesem Fall aber auf jeden Fall geringer ist, als bei günstiger Radstellung. Somit wird die Gefahr einer fehlerhaften Zuordnung noch zusätzlich reduzierbar, das Erreichen einer sicheren Zuordnung beschleunigt.The received signal can also be obtained in the manner described to assign the transmitter identification to all receiving antennas at the same time Zen. For this purpose, one uses in particular the procedure mentioned in claim 2 se. In doing so, the intensities of the different receivers NEN received signals compared to an identifier and the value of the matrix cell for the combination of transmitter identification and receiving antenna with the largest Intensity increased. After receiving several signals with different identifiers the assignment for all receiving antennas can be created from the matrix. Due to an unfavorable wheel position and thus an unfavorable positioning of the transmitter in relation to the directly adjacent receiving antenna, the Si signal of a transmitter from the directly adjacent receiving antenna with a lower one Intensity can be received as from another receiving antenna. In the In this case, the value of an incorrect matrix cell would be increased in the matrix. To prevent this, the Me described in claim 5 can be advantageous use method. In addition to the signal with the greatest intensity, this also becomes determined with the second largest. Returns the difference between these two values If the value is above a certain limit, the value of the matrix becomes cell that belongs to the greatest intensity increases. Is the value of the difference ever but below this limit, the measured value is rejected. This before the underlying idea is that with an unfavorable wheel position there is the possibility that an antenna other than the directly assigned antenna The highest intensity signal receives the difference from the second largest intensity in this case, however, is in any case less than with a favorable wheel position. This further reduces the risk of incorrect assignment, accelerates the achievement of a secure assignment.

Um das Zuordnungsverfahren zu beschleunigen, lassen sich die in den Ansprü­ chen 6 und 7 beschriebenen Weiterbildungen des erfindungsgemäßen Verfah­ rens anwenden. Wird, wie im Anspruch 6 beschrieben, der Wert der Matrixzelle nicht um einen festen Wert erhöht, sondern um einen mit der Intensitätsdifferenz gewichteten Wert, so wird dies dazu führen, daß sich die Matrixzelle mit dem ma­ ximalen Wert rascher ermitteln läßt. Entsprechend kann man dann, wenn man le­ diglich die Ereignisse zählt, daß ein Signal mit bestimmter Kennung von einer be­ stimmten Antenne mit maximaler Intensität empfangen wurde, die Zählrate ge­ wichten, indem man z. B. dann, wenn die Intensität eines Signals mit bestimmter Kennung an einer Antenne um 10% höher war als an der Antenne, bei der das­ selbe Signal mit der zweitstärksten Intensität auftrat, das Ereignis 1-fach zählt, bei wenigstens 20% höherer Intensität das Ereignis 2-fach zählt, bei wenigstens 30% höherer Intensität 3-fach zählt, usw.In order to accelerate the allocation process, the in the claims Chen 6 and 7 described developments of the inventive method Apply rens. As described in claim 6, the value of the matrix cell not increased by a fixed value, but by one with the difference in intensity  weighted value, this will lead to the matrix cell with the ma ximal value can be determined more quickly. Accordingly, if you le diglich the events counts that a signal with a certain identifier from a be tuned antenna was received with maximum intensity, the count rate ge weight by z. B. when the intensity of a signal with certain Identification on an antenna was 10% higher than on the antenna where the same signal with the second strongest intensity occurred, the event counts once, with at least 20% higher intensity the event counts twice, with at least 30% higher intensity triple counts, etc.

Zusätzlich kann man, wie im Anspruch 7 beschrieben, die Empfangsantennen mit bereits zugeordneter Senderkennung aus dem weiteren Zuordnungsverfahren herausnehmen. Das heißt, daß nach Ermittlung der ersten Zuordnung nur noch die Intensitäten der verbliebenen Empfangsantennen verglichen werden müssen.In addition, as described in claim 7, the receiving antennas already assigned transmitter identifier from the further allocation process remove. This means that after determining the first assignment, only the intensities of the remaining receiving antennas must be compared.

Insgesamt wird so eine sichere und schnelle Zuordnung erreicht, die aufgrund ih­ rer selbsttätigen Arbeitsweise mögliche Bedienungsfehler ausschließt. Durch die in Anspruch 8 beschriebene Weiterbildung der Erfindung läßt sich erreichen, daß auch die Vertauschungen der Sender durch mögliche Radwechsel registriert wer­ den, ohne daß ein Eingriff von außen in das System nötig wird. Dabei wird in re­ gelmäßigen Zeitabständen der Wert der Matrixzellen für Sender bei zugeordne­ ten Empfangsantennen auf einen festen Wert Ds gesetzt, der Wert der Matrixzel­ len für Sender bei nicht zugeordneten Empfangsantennen dagegen auf Null. Der Wert Ds kann dann dazu dienen eine Zeit festzusetzen, nach der die Zuordnung erneut bestimmt wird. Dies könnte z. B. dadurch erreicht werden, daß von dem fe­ sten Wert Ds in definierten Zeitabständen heruntergezählt wird. Hat der Inhalt der betreffenden Matrixzellen dann den Wert Null erreicht, so wird die Zuordnung er­ neut ermittelt.Overall, a safe and quick assignment is achieved, which is based on i automatic operation excludes possible operating errors. Through the Further development of the invention described in claim 8 can be achieved in that also the exchanges of the transmitters by possible wheel changes who registered without external intervention in the system. It is in right the value of the matrix cells for transmitters at assigned intervals th receiving antennas set to a fixed value Ds, the value of the matrix cell len for transmitters with unassigned receiving antennas, however, to zero. Of the Value Ds can then serve to set a time after which the assignment is determined again. This could e.g. B. can be achieved by the fe most value Ds is counted down at defined time intervals. Has the content of the relevant matrix cells then reaches the value zero, the assignment becomes newly determined.
