Abstract
Description
Die Erfindung betrifft ein Verfahren zur Positionsbestimmung von funkgebundenen Rad- oder Reifensensoren, von ein- oder mehrspurigen Fahrzeugen.The The invention relates to a method for determining the position of radio-bound Wheel or tire sensors from single or multi-lane vehicles.
Sensoren, die physikalische Parameter an Rädern von Fahrzeugen, zum Beispiel Reifenparameter an Kraftfahrzeugreifen wie Luftdruck, Temperatur usw. messen, teilen ihre Meßdaten und eine Identnummer über Funk an eine Empfangs- und Anzeigeeinheit im Fahrzeug mit. Damit die Anzeigeeinheit weiß, zu welcher Reifenposition im Fahrzeug die entsprechende Identnummer gehört, muß sowohl bei Erst-Installation wie auch bei Veränderungen (Reifenwechsel) eine Zuordnung erfolgen.sensors the physical parameters on wheels of vehicles, for example tire parameters on motor vehicle tires such as air pressure, temperature, etc., share their measurement data and an identification number above Radio to a receiving and display unit in the vehicle. In order to the display unit knows to which tire position in the vehicle the corresponding ID number heard, must both with first installation as well as with changes (tire change) one Assignment done.
Eine bekannte Lösung des Problems besteht darin, pro Rad eine Antenne möglichst nahe zu installieren. Wenn die Reichweite der Funkverbindung dann hinreichend klein ist, ist eine Zuordnung direkt gegeben.A known solution The problem is to have one antenna per wheel if possible close to install. If the range of the radio link then is sufficiently small, an assignment is given directly.
Diese Lösung ist mit dem Nachteil verbunden, die jeweiligen Antennen mit Anschlußleitungen versehen zu müssen, so daß ein hoher Installationsaufwand, einhergehend mit einer Fehleranfälligkeit an den Leitungsanschlüssen einher geht.This solution is associated with the disadvantage that the respective antennas are provided with connecting lines to have to, so that a high installation effort, associated with a susceptibility to errors the line connections goes hand in hand.
Der Erfindung liegt die Aufgabe zugrunde, ein einfaches Verfahren vorzusehen, daß eine Zuordnung der einzelnen Rad- oder Reifensensoren ohne der aufwendigen Installation von Antennen in Sensornähe zuläßt.The The invention has for its object to provide a simple method that a Assignment of the individual wheel or tire sensors without the complex Installation of antennas near the sensor allows.
Diese Aufgabe wird durch die in Patentanspruch 1 beschriebenen Maßnahmen gelöst und durch die in den untergeordneten Pa tentansprüchen beschriebenen Maßnahmen vorteilhaft weitergebildet.This Object is achieved by the measures described in claim 1 solved and through the measures described in the subordinate claims advantageously trained.
Eine Sensorelektronik am Rad oder im Reifen mißt periodisch in kurzen Zeitabständen physikalische Parameter des Rades oder des Reifens, zum Beispiel den Luftdruck. Veränderungen der physikalischen Parameter, die einen Schwellenwert überschreiten, zum Beispiel Druckveränderungen, die eine bestimmte Schwelle überschreiten, werden der Empfangs- und Auswerteeinrichtung über ein Funksignal übermittelt.A Sensor electronics on the wheel or in the tire periodically measure physical at short intervals Parameters of the wheel or tire, for example air pressure. changes the physical parameters that exceed a threshold, for example pressure changes, that cross a certain threshold are transmitted to the receiving and evaluating device via a radio signal.
Diese Empfangs- und Auswerteeinheit wird zur Zuordnung der Rad- oder Reifenposition am Fahrzeug in einen dafür vorgesehenen Lernmodus versetzt. Dabei wird auch vorbestimmt, welche Radposition zu welchem Zeitpunkt "eingelernt" wird.This The receiving and evaluation unit is used to assign the wheel or tire position on the vehicle in one for it provided learning mode. It is also predetermined which Wheel position at which point in time "learn".
In einer vorteilhaften Ausführungsform wird die Abfolge, der einzulernenden Rad- oder Reifenpositionen, wahlweise durch eine vorbestimmte Reihenfolge, oder durch Einstellungen an der Empfangs- und Auswerteeinheit, durch den Benutzer bestimmt (zum Beispiel bei PKW's zuerst vorne links, dann vorne rechts, dann hinten rechts, dann hinten links).In an advantageous embodiment the sequence of the wheel or tire positions to be taught, either by a predetermined order, or by settings on the receiving and evaluation unit, determined by the user (for example in cars first front left, then front right, then back right, then back left).
Alternativ ist auch eine explizite Eingabe der jeweiligen Radposition in die Empfangs- und Auswerteeinrichtung vor jedem Einlernvorgang einer Rad- oder Reifenposition durchführbar.alternative is also an explicit entry of the respective wheel position in the Receiving and evaluation device before each learning process Wheel or tire position feasible.
Nach der Auswahl der Reihenfolge oder der einzulernenden Rad- oder Reifenposition, verändert der Anwender den durch den Sensor gemessenen physikalischen Parameter, zum Beispiel den Druck des entsprechenden Reifens, bis die Ansprech-Schwelle des Rad- oder Reifensensors sicher überschritten ist. Dies kann im Falle eines Drucksensors durch ablassen oder auffüllen mit Luft geschehen. Nach dem Überschreiten eines Schwellwertes sendet der Rad- oder Reifensensor den aktuellen Wert des physikalischen Parameters zusammen mit einer eindeutigen, ihm zugehörigen Identnummer, wodurch der Empfangs- und Anzeigeeinrichtung die Zuordnung zwischen Identnummer und Reifenposition bekannt wird. Dieses Vorgehen wird für alle Reifen wiederholt. Im Anschluß an den Lernmodus, wird das Empfangsgerät wieder in den normalen Betriebsmodus versetzt. Dies kann wahlweise durch den Benutzer ausgelöst, oder nach dem Einlernen aller bekannten Rad- oder Reifenpositionen, oder nach dem Ende der vorbestimmten Abfolge, oder nach dem Ablauf einer bestimmten Zeit automatisch geschehen.To the selection of the sequence or the wheel or tire position to be taught, changed the User the physical parameter measured by the sensor, for example the pressure of the corresponding tire until the response threshold of the wheel or tire sensor is safely exceeded. This can in the case of a pressure sensor, drain or fill up with Air happen. After passing of a threshold value, the wheel or tire sensor sends the current value of the physical parameter along with a unique, him associated ID number, whereby the receiving and display device the assignment between ID number and tire position. This procedure is for all tires repeated. Following the learning mode, the receiving device will be back put into normal operating mode. This can be done either triggered the user or after learning all known wheel or tire positions, or after the end of the predetermined sequence, or after the expiry happen automatically at a certain time.
Besonders vorteilhaft an diesem Verfahren ist, daß es auch vom Fahrzeugbesitzer oder Halter ohne die Hilfe einer Werkstatt durchgeführt werden kann.Especially The advantage of this method is that it can also be used by the vehicle owner or holder can be done without the help of a workshop.
In der Figur ist Beispielhaft das Verfahren zur Zuordnung von Reifenposition und Identnummer bei Reifensensorsystemen im Empfangs- und Auswertegerät dargestellt. Das Verfahren benutzt bewusst herbeigeführte Änderungen des Reifendrucks, um dem Empfangssystem die Zuordnung mitzuteilen.In the figure is an example of the method for assigning tire position and ID number for tire sensor systems are shown in the receiving and evaluation device. The process uses deliberately induced changes in tire pressure, to notify the receiving system of the assignment.
Das Empfangsgerät wird zuerst in einen Lernmodus versetzt. Nach Aktivieren des Lernmodus wird eine jeweils aktuelle Reifenposition vereinbart. Dies ist auch automatisch möglich durch zum Beispiel die Auswahl einer vorbestimmten Reihenfolge Nach dem Abschluß aller Zuordnungen wird wieder der Betriebsmodus in der Empfangs- und Auswerteeinheit aktiviert, dies ist auch automatisch, zum Beispiel nach Ablauf einer bestimmten Zeit, oder nach dem Einlernen aller Radpositionen, oder durch eine Anwenderaktion, möglich.The receiving device is first put into a learning mode. After activating the learning mode, a current tire position is agreed. This is also possible automatically by, for example, selecting a predetermined sequence. After all assignments have been completed, the operating mode is activated again in the receiving and evaluation unit; this is also automatic, for example after a certain time has elapsed or after the teaching of all wheel positions, or through a user action.
