Anhand der Figur 1, die ausgewählte Sensoren in einem Kraftfahrzeug zeigt, werden Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention will be explained in more detail with reference to FIG. 1, which shows selected sensors in a motor vehicle.
Beschreibung von AusführungsbeispielenDescription of exemplary embodiments
Figur 1 zeigt Sensoren 1 und 6 in einem Kraftfahrzeug, die über einen CAN-Bus miteinander und mit einer Steuereinheit 2 verbunden sind. Alle relevanten Sensoren im Fahrzeug, die eine Beschreibung von Wetter- und/oder Umweltdaten erlauben, werden über die Steuereinheit 2 zyklisch abgefragt und die Daten in einem Datensatz zusammengefasst.FIG. 1 shows sensors 1 and 6 in a motor vehicle, which are connected to one another and to a control unit 2 via a CAN bus. All relevant sensors in the vehicle, the one Description of weather and / or environmental data are queried cyclically via the control unit 2 and summarized the data in a record.
Beispiele für Sensoren dieser Art sind: Regensensor, Außentemperaturfühler, Luftfeuchtesensor und Sonnensensor der Klimaautomatik, Luftgütesensor der automatischen Umluftsteuerung, Umgebungsdrucksensor der Motorsteuerung ...Examples of sensors of this type are: rain sensor, outside temperature sensor, air humidity sensor and sun sensor of the automatic air conditioning, air quality sensor of the automatic air recirculation control, ambient pressure sensor of the engine control ...
Diese Daten werden um eine Ortsinformation des Fahrzeugs, z.B. aus dem Navigationssystem, und eine Zeitinformation ergänzt. Neben den Sensordaten werden auch Zustandsinformationsdaten, insbesondere von ABS/ESP, erfasst mittels der Einheit 3, die indirekt Parameter für Wetter- und/oder Umweltdaten liefert. Beispielhaft sei die Erkennung von Straßenglätte oder Aquaplaning aus Zustandsinformationen von ABS und ESP genannt. Die ohnehin vorhandene Vernetzung aller Systeme in Fahrzeugen mit Datenbussen ermöglicht die Datensammlung ohne zusätzlichen Hardware- Aufwand.These data are stored around location information of the vehicle, e.g. from the navigation system, and a time information supplemented. In addition to the sensor data, state information data, in particular of ABS / ESP, is recorded by means of the unit 3, which indirectly supplies parameters for weather and / or environmental data. As an example, the detection of road slipperiness or aquaplaning from condition information of ABS and ESP is mentioned. The already existing networking of all systems in vehicles with data buses enables data collection without additional hardware effort.
Die Datenübertragung erfolgt z.B. mit einem Mobiltelefon nach einem der üblichen Standards, das mit der Steuereinheit verbunden ist. Die Datensätze/Datentelegramme sind relativ kurz und können mit der Kommunikation zwischen Mobiltelefon und Basisstation (Zentrale) übertragen werden. Ohnehin ist die Kommunikation vom Fahrzeug zu Basisstationen vorgesehen für Anwendungen wie schnelle Hilfe im Falle von Pannen oder Unfällen, aber auch individuelle Routenplanung und Reservierungen. Ebenso sind beliebige andere drahtlose Kommunikationssysteme geeignet.The data transmission takes place e.g. with a mobile phone according to one of the usual standards, which is connected to the control unit. The data sets / data telegrams are relatively short and can be transmitted with the communication between mobile phone and base station (central office). In any case, the communication from the vehicle to base stations is intended for applications such as quick assistance in the event of breakdowns or accidents, but also individual route planning and reservations. Likewise, any other wireless communication systems are suitable.
Natürlich steigt die Güte der gesammelten Daten mit dem zunehmenden Ausstattungsgrad eines Fahrzeugs mit den notwendigen Komponenten (geeignete Umweltsensoren, Ortsbestimmung und drahtlose Kommunikation).Of course, the quality of the collected data increases with the increasing equipment level of a vehicle with the necessary components (suitable environmental sensors, location and wireless communication).
Die gesammelten Daten von Einzelfahrzeugen können in einem zentralen Informationsverarbeitungssystem gebietsübergreifend genutzt werden, um Wettersituationen, insbesondere deren Entwicklungstendenzen, besser vorherzusagen oder Verkehrsteilnehmer rechtzeitig zu warnen/vorzuwarnen. Ein typisches Beispiel sind die häufig auftretendenThe collected data of individual vehicles can be used in a central information processing system across territories in order to better predict weather situations, in particular their development tendencies, or to warn / anticipate road users in time. A typical example is the frequently occurring

For the dispersion area and the movement of rainy areas, snow or black ice areas, taking into account typical climate change values, such as night-time cooling or exposed locations such as bridges, river valleys, etc.
Anhand solcher Modelle werden Warnsignale für bereits eingetretene Situationen oder Vorwarnsignale für voraussichtlich eintretende Situationen erstellt oder allgemeine Informationssignale aufbereitet. Bereits im Fahrzeug gewonnene Verknüpfungen von Sensorsignalen, z.B. für ESP oder ABS, können direkt in den zur Zentrale übertragenen Datensatz integriert werden.On the basis of such models, warning signals are created for situations that have already occurred or warning signals for situations that are likely to occur, or general information signals are processed. Already obtained in the vehicle links of sensor signals, e.g. for ESP or ABS, can be integrated directly into the data record transferred to the central office.
Die Vorwarn-, Warn- bzw. allgemeinen Informationssignale können den Verkehrsteilnehmern über Broadcast, als Abrufsignale oder in Form einer Steuerung von entsprechenden Verkehrszeichen (Aufblinken von Glatteis-, Aquaplaning-Signalen) zur Verfügung gestellt werden. Alternativ oder zusätzlich kann das Navigationsgerät eine entsprechende Signalisierung anzeigen.The prewarning, warning or general information signals can be made available to the road users via broadcast, as polling signals or in the form of a control of corresponding traffic signs (flashing of black ice, aquaplaning signals). Alternatively or additionally, the navigation device can display a corresponding signaling.
Aus den Luftgütesensoren mehrerer Fahrzeuge kann ein Luftgütemodell erstellt werden, welches insbesondere dazu verwendet wird, bestimmte Gebiete für Fahrzeuge mit erhöhtem Schadstoffausstoß, z.B. Dieselfahrzeuge ohne Russfilter, zu sperren oder per entsprechend gesteuerten Verkehrszeichen oder Navigationsdaten diesen bestimmte Fahrtrouten vorzugeben. Für die Erstellung des Luftgütemodells können auch noch andere Sensordaten hinzugezogen werden, um Kriterien zur Bildung von Warnsignalen/Vorwarnsignalen zu erstellen. Bei Regen ist z.B. die Luftbelastung weniger kritisch als bei Nebel und statischem Hochdruck, was bei den Kriterien berücksichtigt werden kann. From the air quality sensors of several vehicles, an air quality model can be created, which is used in particular to identify certain areas for vehicles with increased pollutant emissions, e.g. Diesel vehicles without soot filters, to block or specified by appropriate traffic signs or navigation data to these specific routes. For the creation of the air quality model also other sensor data can be used to create criteria for the formation of warning signals / prewarning signals. In the case of rain, e.g. the air pollution less critical than fog and static high pressure, which can be taken into account in the criteria.
