Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the problem results from the objects with the features of claims 1 and 10. Further advantageous embodiments of the invention will become apparent from the dependent claims.
Hierfür werden mindestens die Daten eines Sensors eines Sichtsystems durch mindestens eine zentrale Recheneinheit gesammelt und über ein Bussystem verteilt. Die Verteilung kann damit unabhängig von der Technologie des Sensors erfolgen. Die Geschwindigkeit der Verteilung auf dem Bussystem ist damit nicht gebunden an eine Geschwindigkeit der Datenaufnahme. Nachfolgende Anwendungen benötigen keine Informationen über den Sensor. Damit ist ein Austausch und/oder eine Integration eines Sensors ohne Anpassungen der Anwendungen möglich.For this will be at least the data of a sensor of a vision system by at least a central processing unit collected and distributed over a bus system. The distribution can be independent done by the technology of the sensor. The speed of Distribution on the bus system is not bound to a speed the data recording. Subsequent applications do not need information about the Sensor. This is an exchange and / or integration of a Sensors without adjustments of the applications possible.
In einer bevorzugten Ausführungsform ist mindestens ein Sensor des Sichtsystems als Kamera ausgebildet. Kameradaten ermöglichen eine umfassende Beobachtung des Fahrzeugumfelds. Durch die Trennung des Datensammelns von einer Verarbeitung der Bilddaten ist auch die große Datenmenge der Kameradaten ohne Datenverluste verarbeitbar.In a preferred embodiment At least one sensor of the vision system is designed as a camera. Allow camera data a comprehensive observation of the vehicle environment. By the separation collecting data from processing the image data is also the size Data volume of the camera data can be processed without data loss.
In einer weiteren Ausführungsform ist die Recheneinheit mit einer Schnittstelle zu mindestens einem Fahrzeugbus ausgebildet. Dadurch werden durch die Recheneinheit weitere Fahrzeug-Informationen den Anwendungen zur Verfügung gestellt, ohne dass diese hierfür mit entsprechenden Schnittstellen auszubilden sind.In a further embodiment is the arithmetic unit with an interface to at least one Vehicle bus trained. This is done by the arithmetic unit additional vehicle information provided to the applications, without that for this are to be formed with appropriate interfaces.
In einer weiteren Ausführungsform ist die Schnittstelle als CAN-Bus-Schnittstelle ausgebildet. Fahrzeug- Informationen werden durch Fahrzeug-Steuergeräte in ein Bussystem gestellt und verteilt. In den letzten Jahren hat sich das CAN-Bussystem als Standard in Fahrzeugen durchgesetzt. Daneben ist es jedoch auch denkbar, die Recheneinheit mit Schnittstellen zu einem Sub-Bussystem wie LIN und/oder einem zeitgesteuerten System wie Time Triggered Protocol oder FlexRay auszubilden.In a further embodiment the interface is designed as a CAN bus interface. Vehicle- Information is put into a bus system by vehicle control units and distributed. In recent years, the CAN bus system has become known as Standard enforced in vehicles. But it is the same conceivable, the arithmetic unit with interfaces to a sub-bus system like LIN and / or a timed system like Time Triggered Protocol or FlexRay train.
In einer weiteren bevorzugten Ausführungsform ist das Bussystem zur Verteilung der Daten des/der Sensors/Sensoren als Gigabit Ethernet Bus ausgebildet. Der Gigabit Ethernet Bus hat einen Durchsatz von bis zu 0,75M Pixel bei 25 fps (frames per second), 32 Bit Farbe. Dieser Durchsatz ist ausreichend für die Anforderungen bekannter Bildverarbeitungsprogramme.In a further preferred embodiment is the bus system for distributing the data of the sensor (s) designed as a Gigabit Ethernet bus. The Gigabit Ethernet Bus has a throughput of up to 0.75M pixels at 25 fps (frames per second), 32 bit color. This throughput is sufficient for the requirements known Image processing applications.
In einer weiteren bevorzugten Ausführungsform umfasst die zentrale Recheneinheit einen Listener. Der Listener überwacht Veränderungen, der durch die zentrale Recheneinheit bereitgestellten Informationen. Bei einer Veränderung der Informationen werden entsprechende Anwendungen benachrichtigt. Informationen werden dabei nicht zyklisch, sondern nur bei Bedarf verteilt. Dadurch kann in bestimmten Fällen eine Busbelastung reduziert werden.In a further preferred embodiment the central processing unit comprises a listener. The listener monitors changes, the information provided by the central processing unit. In a change The information is notified to the information. Information is not cyclical, but only when needed distributed. As a result, a bus load can be reduced in certain cases become.
In einer weiteren Ausführungsform ist die zentrale Recheneinheit derart ausgebildet, dass mindestens eine Anwendung auf der zentralen Recheneinheit durchführbar ist. Die Integration verschiedener Rechnersysteme für verschiedene Anwendungen ist aufgrund baulicher und/oder energieverbrauchbedingter Rahmenbedingungen vielfach beschränkt. Es ist daher denkbar, einzelne Anwendungen direkt auf der zentralen Recheneinheit zu integrieren. Die Aufnahme und Weiterleitung der Daten durch die zentrale Recheneinheit hat eine Zeitverzögerung als Folge. Anwendungen, welche durch diese Zeitverzögerung negativ beeinflusst werden könnten, sind ebenfalls auf der zentralen Recheneinheit integrierbar.In a further embodiment the central processing unit is designed such that at least an application on the central processing unit is feasible. The integration of different computer systems for different applications is due to structural and / or energy-related conditions often limited. It is therefore conceivable, individual applications directly on the central To integrate arithmetic unit. The recording and forwarding of Data by the central processing unit has a time delay as Episode. Applications that negatively affect this time delay could be also integrable on the central processing unit.
In einer weitern Ausführungsform ist die zentrale Recheneinheit derart ausgebildet, dass sie dynamisch an angeschlossene Sensoren adaptierbar ist. Eine Adaption oder Anpassung ist beispielsweise in derart denkbar, dass die Datenaufnahmefrequenz des Sensors erfassbar ist. Daneben ist eine Erkennung einer Farbkamera im Unterschied zu einer Graustufenkamera denkbar.In another embodiment the central processing unit is designed such that it is dynamic can be adapted to connected sensors. An adaptation or adaptation is conceivable, for example, in such a way that the data acquisition frequency of the Sensors can be detected. Next to it is a recognition of a color camera unlike a grayscale camera conceivable.
In einer weiteren Ausführungsform senden die Anwendungen ihre Daten an mindestens eine weitere zentrale Recheneinheit, welche mit mindestens einer Schnittstelle zu einem Fahrzeug-Bussystem ausgebildet ist. Dadurch können Ergebnisse der Anwendungen durch ein zweites Bussystem verteilt und an Fahrzeug-Anwendungen übermittelt werden. Das System kann für die Verteilung dieser Daten ausgelegt werden und unterliegt keinen Einschränkungen aufgrund der Anforderungen der Bilddaten. Durch die Ausbildung mit einem zweiten Bussystem können auch Engpässe auf den Bussystemen vermieden werden.In another embodiment, send the applications their data to at least one other central processing unit, which is formed with at least one interface to a vehicle bus system. As a result, results of the applications can be distributed by a second bus system and transmitted to vehicle applications. The system can be designed to distribute this data and is not limited by the requirements of the image data. The training with a second bus system and bottlenecks on the bus systems can be avoided.
