Titel title
Konfigurieren eines Verwaltungssystems für einen Parkplatz  Configure a management system for a parking lot
Die Erfindung betrifft ein Verwaltungssystem für einen Parkplatz. Insbesondere betrifft die Erfindung die Konfiguration des Verwaltungssystems. The invention relates to a management system for a parking lot. In particular, the invention relates to the configuration of the management system.
Auf einem Parkplatz sind mehrere Stellflächen zum Abstellen von Kraftfahrzeugen vorgesehen. Um einen Belegt-Zustand der Absteilfläche zu bestimmen, ist jeder Absteilfläche ein Fahrzeugsensor zugeordnet. Der Sensor bestimmt das Vorhandensein eines Kraftfahrzeugs in einem Abtastbereich beispielsweise auf der Basis einer kapazitiven Messung oder mittels Ultraschall. Ein auf den Belegungszustand der Absteilfläche hinweisendes Signal wird an eine zentrale Einrichtung übermittelt. In der zentralen Einrichtung können dann beispielsweise Reservierungen für unbelegte Absteilflächen durchgeführt werden. In a parking lot several parking spaces are provided for parking motor vehicles. In order to determine a busy state of the Absteilfläche, each Absteilfläche a vehicle sensor is assigned. The sensor determines the presence of a motor vehicle in a scanning region, for example on the basis of a capacitive measurement or by means of ultrasound. An indicative of the occupancy state of the Absteilfläche signal is transmitted to a central facility. In the central facility, for example, reservations for unused parking areas can then be carried out.
Um das Verwaltungssystem in Betrieb zu nehmen, müssen Positionen der Fahrzeugsensoren bekannt sein. Üblicherweise werden diese Positionen vorbestimmt und die Sensoren erst anschließend an den bestimmten Positionen installiert. Dies kann mit erheblichem manuellem Aufwand verbunden sein, wodurch Kosten und Fehler entstehen können. To put the management system into operation, positions of the vehicle sensors must be known. Usually, these positions are predetermined and the sensors are then installed at the specific positions. This can be associated with considerable manual effort, which can result in costs and errors.
Es ist Aufgabe der vorliegenden Erfindung, eine Technik zur vereinfachten Konfiguration eines Verwaltungssystems für einen Parkplatz anzugeben. Die Erfin- dung löst diese Aufgabe mittels der Gegenstände der unabhängigen Ansprüche.It is an object of the present invention to provide a technique for simplified configuration of a parking management system. The invention solves this problem by means of the subject matters of the independent claims.

Offenbarung der Erfindung Disclosure of the invention
Ein Fahrzeugsensor zur Überwachung einer Stellfläche für ein Kraftfahrzeug um- fasst eine Abtasteinrichtung zur Erfassung eines Kraftfahrzeugs, eine Positioniereinrichtung, eine Verarbeitungseinrichtung zur Bestimmung eines Belegungssignals, das darauf hinweist, ob das Kraftfahrzeug erfasst wurde, und eine Kommunikationseinrichtung zur Übermittlung einer Position des Fahrzeugsensors und des Belegungssignals. A vehicle sensor for monitoring a footprint for a motor vehicle comprises a scanning device for detecting a motor vehicle, a Positioning device, a processing device for determining an occupancy signal indicating whether the motor vehicle has been detected, and a communication device for transmitting a position of the vehicle sensor and the occupancy signal.
Mittels der Positioniereinrichtung kann der Fahrzeugsensor seine eigene Position selbst feststellen, sodass das positionsbezogene Belegungssignal durch eine zentrale Stelle eines Verwaltungssystems für einen Parkplatz, der die Stellfläche umfasst, unmittelbar ausgewertet werden kann. Das Verwaltungssystem kann dadurch selbstkonfigurierend ausgeführt sein. Der Fahrzeugsensor kann leicht an eine andere Stelle verbracht werden, sodass beispielsweise Stellflächen oder ein Verkehrsweg auf dem Parkplatz leicht neu angeordnet werden können. Ein Austausch eines defekten Fahrzeugsensors kann vollständig transparent für das Verwaltungssystem erfolgen. By means of the positioning device, the vehicle sensor can determine its own position itself, so that the position-related occupancy signal can be evaluated directly by a central point of a management system for a parking space that includes the footprint. The management system can thereby be designed to be self-configuring. The vehicle sensor can easily be moved to another location, so that, for example, parking areas or a traffic route in the parking lot can be easily rearranged. An exchange of a defective vehicle sensor can be made completely transparent to the management system.
In einer ersten Alternative umfasst die Positioniereinrichtung einen Empfänger für Positionssignale eines Satellitennavigationssystems. Liegt die Stellfläche unter freiem Himmel, so kann mittels des Navigationsempfängers eine einfache, schnelle und kostengünstige Bestimmung der Position des Fahrzeugsensors durchgeführt werden. Dabei kann ebenfalls eine Triangulation bezüglich Positionen von Satelliten durchgeführt werden; bevorzugterweise erfolgt die Bestimmung einer Position aus Satellitensignalen jedoch durch den Empfänger für Positionssignale des Satellitennavigationssystems. Nach Außen stellt der Empfänger dabei eine fertig bestimmte Position bereit, die üblicherweise als Längen- und Breitengrad und eine optionale Höhe bezüglich einem vorbestimmten geodätischen Referenzsystem wie dem WGS84 definiert ist. Wird der Fahrzeugsensor in einiger Höhe über der Stellfläche angebracht, so kann der Navigationsempfänger durchgehend arbeiten. Ist der Fahrzeugsensor zur Montage auf oder in einer Bodenfläche der Stellfläche vorgesehen, so kann er seine Position mittels des Na- vigationsempfängers bestimmen, bevor ein Kraftfahrzeug über ihm abgestellt wird und dabei den Empfang der Satellitensignale stört. In a first alternative, the positioning device comprises a receiver for position signals of a satellite navigation system. If the footprint lies under the open sky, a simple, fast and cost-effective determination of the position of the vehicle sensor can be carried out by means of the navigation receiver. In doing so, a triangulation with respect to positions of satellites can likewise be carried out; Preferably, however, the determination of a position of satellite signals is carried out by the receiver for position signals of the satellite navigation system. Outwardly, the receiver thereby provides a ready-determined position, which is usually defined as latitude and longitude and an optional altitude with respect to a predetermined geodetic reference system such as the WGS84. If the vehicle sensor is mounted at a certain height above the footprint, the navigation receiver can work continuously. If the vehicle sensor is intended to be mounted on or in a bottom surface of the footprint, it can determine its position by means of the navigation receiver before a motor vehicle is parked above it, thereby disturbing the reception of the satellite signals.
In einer zweiten Alternative ist die Positioniereinrichtung dazu eingerichtet, die Position mittels Triangulation bezüglich mehrerer drahtloser Sender im Bereich der Stellfläche zu bestimmen. Dazu sollten die Positionen der drahtlosen Sender bereits bekannt sein; die Triangulation erfolgt dann in bekannter Weise. Diese Vorgehensweise kann insbesondere vorteilhaft sein, wenn der Einsatz eines Navigationsempfängers nicht möglich ist, beispielsweise in einem Parkhaus oder in einer Tiefgarage. In einer dritten Alternative werden die Positionsbestimmungen des Empfänger für Positionssignale eines Satellitennavigationssystems und der Triangulation bezüglich der stellflächenbasierten miteinander kombiniert. Dabei kann eine kombinierte Triangulation bezüglich aller Signalquellen erfolgen. In a second alternative, the positioning device is adapted to determine the position by means of triangulation with respect to a plurality of wireless transmitters in the area of the footprint. For this purpose, the positions of the wireless transmitter should already be known; The triangulation then takes place in a known manner. These Approach can be particularly advantageous if the use of a navigation receiver is not possible, for example in a parking garage or in an underground car park. In a third alternative, the position determinations of the receiver for position signals of a satellite navigation system and of the triangulation with respect to the platform-based are combined with one another. In this case, a combined triangulation with respect to all signal sources can take place.
In einer Weiterentwicklung ist die Kommunikationseinrichtung dazu eingerichtet, drahtlos mit den Sendern zu kommunizieren. Die Sender können insbesondere WLAN-Knotenpunkte umfassen, sodass die Kommunikation und die Bestimmung von Signalen für die Triangulation miteinander integriert durchgeführt werden können. Die Kommunikationseinrichtung und die Positioniereinrichtung des Fahrzeugsensors können miteinander integriert ausgeführt werden. In einer weiteren Alternative können auch mehrere der genannten In a further development, the communication device is set up to communicate wirelessly with the transmitters. In particular, the transmitters can comprise WLAN nodes, so that the communication and the determination of signals for the triangulation can be carried out integrated with one another. The communication device and the positioning of the vehicle sensor can be performed integrated with each other. In a further alternative, several of the mentioned
Positioniertechniken miteinander kombiniert werden.  Positioning techniques are combined.
Ein Verwaltungssystem für einen Parkplatz umfasst einen Fahrzeugsensor zur Bereitstellung eines Belegungssignals, das darauf hinweist, ob ein Kraftfahrzeug im Bereich des Fahrzeugsensors erfasst wurde, mehrere drahtlose Kommunikationseinrichtungen zur Kommunikation mit dem Fahrzeugsensor und eine Verarbeitungseinrichtung, die dazu eingerichtet ist, eine Position des Fahrzeugsensors mittels Triangulation bezüglich der Kommunikationseinrichtungen zu bestimmen und eine Verkehrssituation auf dem Parkplatz auf der Basis der Position des Belegungssignals zu bestimmen. A management system for a parking lot includes a vehicle sensor for providing an occupancy signal indicative of whether a motor vehicle has been detected in the area of the vehicle sensor, a plurality of wireless communication devices for communicating with the vehicle sensor, and a processing device configured to triangulate a position of the vehicle sensor with respect to the communication facilities and to determine a traffic situation in the parking lot based on the position of the occupancy signal.
Die Position des Fahrzeugsensors kann dabei seitens des Verwaltungssystems bestimmt werden, indem drahtlose Kommunikationssignale die Basis für eine Triangulation bilden. Die Triangulation kann seitens des Verwaltungssystems leicht für eine Vielzahl Fahrzeugsensoren durchgeführt werden. The position of the vehicle sensor can be determined by the management system in that wireless communication signals form the basis for a triangulation. The triangulation can be easily performed by the management system for a variety of vehicle sensors.
Es ist besonders bevorzugt, dass der Fahrzeugsensor so ausgestattet ist wie oben beschrieben ist. Die Positionsbestimmung des Fahrzeugsensors kann dann flexibel auf unterschiedliche Weisen erfolgen. In einer besonders bevorzugten Ausführung sind mehrere Fahrzeugsensoren von dem Verwaltungssystem umfasst, wobei die Fahrzeugsensoren dazu eingerichtet sind, drahtlos miteinander zu kommunizieren und ein Fahrzeugsensor dazu eingerichtet ist, seine Position mittels Triangulation bezüglich wenigstens ei- nes anderen Fahrzeugsensors zu bestimmen. Die Fahrzeugsensoren können beispielsweise nacheinander ihre Positionen bestimmen und gegeneinander plausibilisieren. Ein Fahrzeugsensor, der seine Position bereits bestimmt hat, kann als Referenzpunkt für eine Triangulation verwendet werden, um die Position eines weiteren Fahrzeugsensors zu bestimmen. Auch unter geometrisch oder empfangstechnisch schwierigen Bedingungen kann so die Position eines Fahrzeugsensors bestimmt werden. Einer der Fahrzeugsensoren kann so seine Position auch nur bezüglich anderer Fahrzeugsensoren bestimmen. Die anderen Fahrzeugsensoren verfügen dann bevorzugterweise über die Möglichkeit, ihre eigenen Positionen selbst möglichst schnell zu bestimmen, beispielsweise mittels Empfängern für Positionssignale eines Satellitennavigationssystems. Einer oder mehrere der anderen Fahrzeugsensoren können ihre Positionen auch auf der Basis einer manuellen Vermessung kennen. Das Verwaltungssystem kann so in verbesserter Weise selbst konfigurierend ausgeführt sein. Ein Verfahren zur Verwaltung eines Parkplatzes mittels eines Fahrzeugsensors zur Überwachung einer Stellfläche des Parkplatzes umfasst Schritte des Bestimmens einer Position des Fahrzeugsensors mittels Radiowellen, des Empfangens, vom Fahrzeugsensor, eines Belegungssignals, das darauf hinweist, ob im Bereich des Fahrzeugsensors ein Kraftfahrzeug erfasst wurde, und des Bestim- mens einer Verkehrssituation auf dem Parkplatz auf der Basis der Position und des Belegungssignals. Durch die Positionsbestimmung des Fahrzeugsensors mittels Radiowellen kann ein Vermessungsaufwand für den Fahrzeugsensor klein gehalten sein. Die Position kann beliebig oft bestimmt werden, sodass über mehrere Bestimmungen eine erhöhte Genauigkeit erzielt werden kann. Außer- dem kann der Fahrzeugsensor mit verringertem Aufwand an eine neue Position verbracht werden. It is particularly preferred that the vehicle sensor is equipped as described above. The position determination of the vehicle sensor can then be carried out flexibly in different ways. In a particularly preferred embodiment, a plurality of vehicle sensors are included in the management system, wherein the vehicle sensors are configured to wirelessly communicate with each other and a vehicle sensor is configured to determine its position by triangulation with respect to at least one other vehicle sensor. For example, the vehicle sensors can sequentially determine their positions and make them plausible against each other. A vehicle sensor that has already determined its position may be used as a reference point for a triangulation to determine the position of another vehicle sensor. The position of a vehicle sensor can thus also be determined under geometric or reception-technically difficult conditions. One of the vehicle sensors can thus determine its position only with respect to other vehicle sensors. The other vehicle sensors then preferably have the ability to determine their own positions as quickly as possible, for example by means of receivers for position signals of a satellite navigation system. One or more of the other vehicle sensors may also know their positions based on a manual survey. The management system can thus be designed to be self-configuring in an improved manner. A method for managing a parking space by means of a vehicle sensor for monitoring a parking space of the parking lot comprises steps of determining a position of the vehicle sensor by means of radio waves, receiving, from the vehicle sensor, an occupancy signal indicating whether a motor vehicle has been detected in the region of the vehicle sensor, and determining a traffic situation in the parking lot based on the position and the occupancy signal. By determining the position of the vehicle sensor by means of radio waves, a surveying effort for the vehicle sensor can be kept small. The position can be determined as often as required so that increased accuracy can be achieved across multiple determinations. In addition, the vehicle sensor can be moved to a new position with reduced effort.
In einer ersten Variante wird die Position seitens des Fahrzeugsensors mittels eines Empfängers für Positionssignale eines Satellitennavigationssystems be- stimmt. In einer zweiten Variante, die optional mit der ersten Variante kombinierbar ist, wird die Position mittels Triangulation bezüglich mehrerer drahtloser Kommunikationseinrichtungen bestimmt, die am Parkplatz angebracht sind. In weiteren Untervarianten kann die Triangulation seitens des Fahrzeugsensors oder seitens der Kommunikationseinrichtungen durchgeführt werden. In a first variant, the position is determined by the vehicle sensor by means of a receiver for position signals of a satellite navigation system. In a second variant, which is optionally combinable with the first variant, the position is triangulated with respect to several wireless Communication devices that are attached to the parking lot. In further sub-variants, the triangulation can be performed by the vehicle sensor or by the communication devices.
Ein Computerprogrammprodukt umfasst Programmcodemittel zur Durchführung des beschriebenen Verfahrens, wenn das Computerprogrammprodukt auf einer Verarbeitungseinrichtung abläuft oder auf einem computerlesbaren Datenträger gespeichert ist. A computer program product comprises program code means for carrying out the described method when the computer program product runs on a processor or is stored on a computer-readable medium.

Figur 1 zeigt einen Parkplatz 100 und ein Verwaltungssystem 105 zur Verwaltung des Parkplatzes 100. FIG. 1 shows a parking lot 100 and a management system 105 for managing the parking space 100.
Der Parkplatz 100 umfasst mehrere Stellflächen 1 10, jeweils zum Abstellen eines Kraftfahrzeugs 1 15. Zwischen den Stellflächen 1 10 können noch Verkehrsflächen vorgesehen sein, die im Lichte der vorliegenden Erfindung im Folgenden wie die Stellflächen 1 10 behandelt werden. Das Verwaltungssystem 105 umfasst mehrere Fahrzeugsensoren 120 im Bereich des Parkplatzes 100, wobei üblicherweise jeder Stellfläche 1 10 ein Fahrzeugsensor 120 zugeordnet ist, eine zentrale Einrichtung 125 und wenigstens eine Kommunikationseinrichtung 130. Die Kommunikationseinrichtung 130 kann ein drahtgebundenes Netz zur Verbindung der Fahrzeugsensoren 120 mit der zentralen Einrichtung 125 umfassen. Bevorzugterweise erfolgt die Kommunikation zwischen den Fahrzeugsensoren 120 und der zentralen Einrichtung 125 jedoch drahtlos, wobei wenigstens eine der Kommunikationseinrichtungen 130 einen drahtlosen Sender/Empfänger um- fasst. Bevorzugterweise wird zur drahtlosen Übermittlung WLAN-Technologie verwendet und wenigstens eine der Kommunikationseinrichtungen 130 umfasst einen WLAN-Knotenpunkt. The parking lot 100 includes a plurality of shelves 1 10, each for parking a motor vehicle 1 15. Between the shelves 1 10 may still be provided traffic areas, which are treated in the light of the present invention hereinafter as the shelves 1 10. The management system 105 comprises a plurality of vehicle sensors 120 in the area of the parking space 100, wherein usually each footprint 1 10 is associated with a vehicle sensor 120, a central device 125 and at least one communication device 130. The communication device 130 may be a wired network for connecting the vehicle sensors 120 with the central Device 125 include. The communication between the vehicle sensors preferably takes place 120 and the central device 125 wirelessly, however, wherein at least one of the communication devices 130 comprises a wireless transceiver. For wireless transmission, WLAN technology is preferably used and at least one of the communication devices 130 comprises a WLAN node.
Die Fahrzeugsensoren 120 verwenden zur Bestimmung des Vorhandenseins eines Kraftfahrzeugs 1 15 in einem Abtastbereich eine oder mehrere übliche Techniken wie Ultraschall, Radar, Lidar, eine Lichtschranke, einen kapazitiven Sensor oder eine Kamera. Auf der Basis der Abtastung erzeugt jeder FahrzeugsensorThe vehicle sensors 120 use one or more conventional techniques such as ultrasound, radar, lidar, a light barrier, a capacitive sensor, or a camera to determine the presence of a motor vehicle 15 in a sensing area. Based on the scan, each vehicle sensor generates
120 ein Belegungssignal, das darauf hinweist, ob sich ein Kraftfahrzeug 1 15 im Abtastbereich des jeweiligen Fahrzeugsensors 120 befindet. Das Belegungssignal wird über die Kommunikationseinrichtung 130 an die zentrale Einrichtung 125 übermittelt. Die zentrale Einrichtung 125 ist bevorzugterweise dazu eingerichtet, auf der Basis der Belegungssignale der Fahrzeugsensoren 120 eine Verkehrssituation auf dem Parkplatz 100 zu bestimmen. Weitergehende Verwaltungsaufgaben wie eine Reservierungsverwaltung, ein Abrechnungssystem, ein Verkehrsleitsystem oder ein anderes Untersystem zur Verwaltung des Parkplatzes 100 können darauf aufbauen. 120 an occupancy signal indicating whether a motor vehicle 15 is in the scanning area of the respective vehicle sensor 120. The occupancy signal is transmitted via the communication device 130 to the central device 125. The central device 125 is preferably configured to determine a traffic situation on the parking space 100 on the basis of the occupancy signals of the vehicle sensors 120. Further administrative tasks, such as reservation management, billing system, traffic management system, or other subsystem for managing parking lot 100 may be based thereon.
Die Verkehrssituation ist bevorzugterweise gebildet auf der Basis der Belegungssignale aller Fahrzeugsensoren 120 und der Positionen der Fahrzeugsensoren 120. Die Position jedes Fahrzeugsensors 120 wird üblicherweise einmalig für einen längeren Zeitraum bestimmt, indem der Fahrzeugsensor 120 gegenüber dem Parkplatz 100 bzw. einer Stellfläche 1 10 nicht bewegt wird. Dabei wird vorgeschlagen, dass das Verwaltungssystem 105 dazu eingerichtet ist, die Position eines Fahrzeugsensors 120 ohne Zuhilfenahme äußerer Kräfte zu bestimmen. In einer Ausführungsform ist ein Fahrzeugsensor 120 mit einer autonomen Einrichtung zur Bestimmung seiner Position ausgestattet, wie unten mit Bezug auf Figur 3 noch genauer beschrieben wird. In einer anderen Ausführungsform wird dieThe traffic situation is preferably formed on the basis of the occupancy signals of all vehicle sensors 120 and the positions of the vehicle sensors 120. The position of each vehicle sensor 120 is usually determined once for a longer period of time by the vehicle sensor 120 not moving relative to the parking lot 100 or a footprint 110 becomes. It is proposed that the management system 105 is set up to determine the position of a vehicle sensor 120 without the aid of external forces. In one embodiment, a vehicle sensor 120 is provided with autonomous means for determining its position, as described in more detail below with reference to FIG. In another embodiment, the
Position des Fahrzeugsensors 120 mittels Triangulation bestimmt. Zur Erläuterung dieses Prinzips werden mit Bezug auf Figur 1 ein erster exemplarischer Fahrzeugsensor 135 und ein zweiter exemplarischer Fahrzeugsensor 140 betrachtet. Eine Triangulation des ersten Fahrzeugsensors 135 erfolgt üblicherweise bezüglich wenigstens dreier Kommunikationseinrichtungen 130. Auf der Basis von Radiowellen werden Abstände zwischen dem ersten Fahrzeugsensor 135 und den Kommunikationseinrichtungen 130 bestimmt und auf der Basis bekannter Positi- onen der Kommunikationseinrichtungen 130 wird die Position des ersten Fahrzeugsensors 135 bestimmt. Diese Bestimmung kann alternativ seitens des ersten Fahrzeugsensors 135 oder beispielsweise seitens der zentralen Einrichtung 125, jeweils auf der Basis empfangener Radiosignale, durchgeführt werden. Die Position des zweiten Fahrzeugsensors 140 kann auf die gleiche Weise bestimmt werden, wobei jedoch wenigstens eine der Kommunikationseinrichtungen 130 durch einen Fahrzeugsensor 120 ersetzt ist, dessen Position bereits bekannt ist, hier im vorliegenden Beispiel durch den ersten Fahrzeugsensor 135. Die Positionsbestimmung kann so fortschreitend für alle Fahrzeugsensoren 120 des Verwaltungssystems 105 durchgeführt werden. Position of the vehicle sensor 120 determined by triangulation. To explain this principle, with reference to FIG. 1, a first exemplary vehicle sensor 135 and a second exemplary vehicle sensor 140 are considered. Triangulation of the first vehicle sensor 135 is usually carried out with respect to at least three communication devices 130. Distances between the first vehicle sensor 135 and the communication devices 130 are determined on the basis of radio waves, and the position of the first vehicle sensor 135 is determined on the basis of known positions of the communication devices 130 , This determination may alternatively be carried out by the first vehicle sensor 135 or, for example, by the central device 125, in each case on the basis of received radio signals. The position of the second vehicle sensor 140 may be determined in the same manner, but at least one of the communication devices 130 is replaced by a vehicle sensor 120 whose position is already known, here in the present example by the first vehicle sensor 135. The position determination can thus progressively all vehicle sensors 120 of the management system 105 are performed.
Figur 2 zeigt Optionen für die Bestimmung der Position eines Fahrzeugsensors 120 für das Verwaltungssystem 105 von Figur 1. Obwohl das in Figur 2 dargestellte Diagramm im Wesentlichen Alternativen aufzeigt, wird im Folgenden auf einzelne Schritte Bezug genommen. Korrespondierende Verfahren können dadurch erleichtert aus Figur 2 abgeleitet werden. FIG. 2 shows options for determining the position of a vehicle sensor 120 for the management system 105 of FIG. 1. Although the diagram illustrated in FIG. 2 essentially shows alternatives, individual steps will be referred to below. Corresponding methods can be derived from FIG. 2 in a simplified manner.
Das Ablaufdiagramm 200 beginnt in einem Schritt 205 mit dem Zweck, die Position eines Fahrzeugsensors 120 aus Figur 1 zu bestimmen. In einer ersten Alter- native verfügt der Fahrzeugsensor 120 über ein autonomes Mittel zur Bestimmung seiner Position, insbesondere einen Empfänger für Positionssignale eines Satellitennavigationssystems (GPS, Galileo, GLONASS etc.). In einer anderen Alternative erfolgt in einem Schritt 215 das Bestimmen der Position mittels Trian- gulieren. Das Triangulieren kann in einem Schritt 220 seitens des Fahrzeugsen- sors 120 durchgeführt werden. Dazu wird in einem Schritt 225 seitens des Fahrzeugsensors 120 eine Kommunikation mit mehreren Kommunikationseinrichtungen 130 oder Fahrzeugsensoren 120 eingeleitet. Die in Figur 2 fett dargestellten Schritte werden potentiell mehrfach durchgeführt, hier bezüglich mehrerer Kommunikationspartner 120, 130. In einem Schritt 230 erfolgt die Kommunikation zu einem oder mehreren Fahrzeugsensoren 120 und in einem Schritt 235 zu einer oder mehreren Kommunikationseinrichtungen 130, die zu einer Infrastruktur des Verwaltungssystems 105 gezählt werden können. Die Schritte 230 und 235 können auch beide ausgeführt werden, sodass die Position des Fahrzeugsensors 120 bezüglich einer gemischten Menge von Fahrzeugsensoren 120 und Kommunikationseinrichtungen 130 bestimmt wird. In einem Schritt 240 werden die Positionen der Kommunikationspartner 120, 130 empfangen. Alternativ dazu können die Positionen der Kommunikationspartner 120, 130 auch auf andere Weise bekannt sein, beispielsweise auf der Basis einer Kommunikation mit der zentralen Einrichtung 125. Es ist zu beachten, dass drahtlose Kommunikationssignale bezüglich Kommunikationspartnern 120, 130, deren Positionen nicht bekannt sind, für die Bestimmung der Position des Fahrzeugsensors 120 nicht verwendet werden können. In einem Schritt 245 wird die Position des Fahrzeugsensors 120 mittels Triangu- lieren bezüglich der Positionen der Kommunikationspartner 120, 130 bestimmt. Dabei wird zu jedem Kommunikationspartner 120, 130 eine Entfernung bestimmt und die Position des Fahrzeugsensors 120 wird auf der Basis der Entfernungen und der Positionen der Kommunikationspartner 120, 130 geometrisch bzw. mit- tels Matrizenrechnung auf bekannte Weise bestimmt. The flowchart 200 begins in a step 205 for the purpose of determining the position of a vehicle sensor 120 of FIG. In a first alternative, the vehicle sensor 120 has an autonomous means for determining its position, in particular a receiver for position signals of a satellite navigation system (GPS, Galileo, GLONASS, etc.). In another alternative, in a step 215, the position is determined by means of triangulation. The triangulation can be performed by the vehicle sensor 120 in a step 220. For this purpose, in a step 225, a communication with a plurality of communication devices 130 or vehicle sensors 120 is initiated by the vehicle sensor 120. The steps shown in bold in FIG. 2 are potentially performed several times, in this case with respect to a plurality of communication partners 120, 130. In a step 230, the communication to one or more vehicle sensors 120 and in a step 235 to one or more communication devices 130, which can be counted to an infrastructure of the management system 105. Steps 230 and 235 may also be performed so that the position of vehicle sensor 120 with respect to a mixed set of vehicle sensors 120 and communication devices 130 is determined. In a step 240, the positions of the communication partners 120, 130 are received. Alternatively, the locations of the communication partners 120, 130 may be known in other ways, for example, based on communication with the central facility 125. It should be noted that wireless communication signals with respect to communication partners 120, 130 whose locations are not known for the determination of the position of the vehicle sensor 120 can not be used. In a step 245, the position of the vehicle sensor 120 is determined by means of triangulation with respect to the positions of the communication partners 120, 130. In this case, a distance to each communication partner 120, 130 is determined and the position of the vehicle sensor 120 is determined on the basis of the distances and the positions of the communication partners 120, 130 geometrically or by means of matrix calculation in a known manner.
In einem Schritt 250 liegt dann die Position des Fahrzeugsensors 120 vor. In a step 250, the position of the vehicle sensor 120 is then present.
Alternativ kann das Triangulieren des Schritts 215 statt in den Schritten 220 ff. seitens des Fahrzeugsensors 120 auch in Schritten 255 ff. seitens der Infrastruktur des Verwaltungssystems 105 bestimmt werden. Dazu erfolgt wieder eine Kommunikation von mehreren Kommunikationspartnern 120, 130 mit dem Fahrzeugsensor 120, die aber üblicherweise nicht vom Fahrzeugsensor 120, sondern von seinen Kommunikationspartnern 120, 130 initiiert wird. Die Kommunikations- partner 120, 130 können in einem Schritt 260 einen oder mehrere andere Fahrzeugsensoren 120 oder in einem Schritt 265 eine oder mehrere Kommunikationseinrichtungen 130 umfassen. Anschließend wird in einem Schritt 270 die Kommunikation zwischen dem Fahrzeugsensor 120 und den Kommunikationspartnern 120, 130 durchgeführt. Wieder muss für jeden verwertbaren Kommuni- kationspartner 120, 130 eine Position bekannt sein, die hier in einem Schritt 275 bestimmt wird. Anschließend erfolgt in einem Schritt 280 das Triangulieren, woraufhin im Schritt 250 die Position des Fahrzeugsensors 120 vorliegt. Alternatively, the triangulation of step 215 may be determined by the vehicle sensor 120 in steps 255 et seq., Rather than in steps 220 et seq., By the infrastructure of the management system 105. For this purpose, communication between a plurality of communication partners 120, 130 with the vehicle sensor 120 takes place again, but is usually not initiated by the vehicle sensor 120 but by its communication partners 120, 130. The communication partners 120, 130 may comprise one or more other vehicle sensors 120 in a step 260 or one or more communication devices 130 in a step 265. Subsequently, in a step 270, the communication between the vehicle sensor 120 and the communication partners 120, 130 is performed. Again, for each exploitable communication partner 120, 130, a position must be known, here in a step 275 is determined. Subsequently, triangulation takes place in a step 280, whereupon in step 250 the position of the vehicle sensor 120 is present.
Es ist zu beachten, dass einige der Schritte bzw. Optionen des Ablaufdiagramms 200 von Figur 2 auch in anderer Reihenfolge durchgeführt werden können, wie sich einem Fachmann ohne weiteres sofort erschließt. It should be noted that some of the steps or options of the flowchart 200 of FIG. 2 may also be performed in a different order, as readily apparent to one skilled in the art.
