Description
Stand der TechnikState of the art
Die Erfindung betrifft ein Verfahren zum Überwachen der Umgebung eines Kraftfahrzeugs, bei dem Situationsdaten erfasst und ausgewertet werden, wobei die Situationsdaten einzelne Aspekte der Umfeldsituation des Fahrzeugs wiedergeben. Des Weiteren betrifft die Erfindung ein Fahrerinformationssystem mit Mitteln zum Überwachen der Fahrzeugumgebung.The invention relates to a method to monitor the surroundings of a motor vehicle in which situation data is recorded and evaluated, whereby the situation data individual aspects of the Show the surroundings of the vehicle. Furthermore concerns the invention a driver information system with means for monitoring the vehicle environment.
Aus der Praxis sind bereits Sicherheitssysteme für Kraftfahrzeuge bekannt, die auf der Auswertung von Situationsdaten basieren. Die Menge und Art der erfassten Situationsdaten hängt wesentlich von den Aufgaben und der Komplexität des Sicherheitssystems ab. Im Rahmen von Rückhaltesystemen werden beispielsweise Beschleunigungssensoren eingesetzt, um die Fahrzeugbewegung zu erfassen, damit diese beim Auslösen der Rückhaltemittel berücksichtigt werden kann. Daneben sind Warnsysteme bekannt, mit denen Gefahrensituationen frühzeitig erkannt werden sollen, um Kollisionen zu vermeiden. Zur Detektion von Objekten in der Fahrzeugumgebung sowie zur Bestimmung der Entfernung und Geschwindigkeit dieser Objekte relativ zum Fahrzeug werden häufig aktive Ultraschallsensoren, Radarsensoren und/oder Infrarotsensoren eingesetzt. Allerdings ermöglichen die damit erfassten Situationsdaten in der Regel keine zuverlässige Klassifizierung des detektierten Objekts, so dass das Sicherheitssystem nicht unterscheiden kann, ob es sich bei dem Objekt um einen Pkw, einen Lkw, einen Fahrradfahrer, einen Fußgänger oder beispielsweise eine Leitplanke handelt. Bekannt ist auch der Einsatz von Kamerasystemen, die neben der Detektion von Objekten und Bestimmung von Entfernung und Geschwindigkeit dieser Objekte eine zuverlässige Objektklassifizierung ermöglichen. Diese ist allerdings relativ aufwendig, sowohl im Hinblick auf die erforderliche Rechenleistung als auch im Hinblick auf die Kosten für ein solches Kamerasystem mit entsprechender Verarbeitungseinheit.Security systems are already in practice for motor vehicles known, which are based on the evaluation of situation data. The The amount and type of the situation data recorded essentially depends on the tasks and complexity of the security system. In the context of restraint systems, for example Accelerometers used to record vehicle movement so that when triggered the restraint is taken into account can be. In addition, warning systems are known to deal with dangerous situations early should be recognized in order to avoid collisions. For detection of objects in the vehicle environment and for determining the distance and The speed of these objects relative to the vehicle often becomes active Ultrasonic sensors, radar sensors and / or infrared sensors are used. However, allow the situation data recorded with it is usually not a reliable classification of the detected object so that the security system does not differentiate whether the object is a car, a truck, a cyclist, a pedestrian or for example a guardrail. The use of Camera systems in addition to the detection of objects and determination a reliable object classification based on the distance and speed of these objects enable. However, this is relatively complex, both with regard to the required computing power as well as in terms of cost for a such a camera system with a corresponding processing unit.
Vorteile der ErfindungAdvantages of invention
Mit der vorliegenden Erfindung wird vorgeschlagen, die Umgebungsgeräusche als zusätzliche Informationsquelle zur Analyse der Umfeldsituation zu nutzen. Dementsprechend wird im Rahmen des erfindungsgemäßen Verfahrens zumindest ein TeiI der Umgebungsgeräusche des Fahrzeugs erfasst und ausgewertet. Ein Fahrerinformationssystem, mit dem die Fahrzeugumgebung zumindest bereichsweise überwacht wird, sollte dazu mit mindestens einem Mikrofon ausgestattet sein und mit Mitteln zum Auswerten des von dem Mikrofon erfassten akustischen Signals.With the present invention suggested the ambient noise as an additional source of information to use for the analysis of the surrounding situation. Accordingly in the context of the method according to the invention at least a part of the ambient noise of the vehicle is recorded and evaluated. A driver information system that uses the vehicle environment monitored at least in some areas should be equipped with at least one microphone and with means for evaluating the acoustic signal detected by the microphone.
Grundsätzlich gibt es verschiedene Möglichkeiten für die Realisierung des erfindungsgemäßen Verfahrens.There are basically several possibilities for the Realization of the method according to the invention.
In einer vorteilhaften Variante des erfindungsgemäßen Verfahrens werden die Umgebungsgeräusche mit Hilfe mindestens eines Richtmikrofons erfasst. In diesem Fall kann das erfasste akustische Signal einer Richtung in der Umgebung des Fahrzeugs bzw. einem Umgebungssegment zugeordnet werden. Dies erweist sich insbesondere dann als vorteilhaft, wenn das Fahrerinformationssystem zusätzlich auch mindestens einen entfernungserfassenden Sensor umfasst, mit dem sich Objekte in diesem von dem Richtmikrofon abgedeckten Umgebungssegment des Fahrzeugs detektieren lassen. Das von dem Richtmikrofon erfasste akustische Signal kann dann in vorteilhafter Weise zur Klassifizierung der von dem entfernungserfassenden Sensor detektierten Objekte herangezogen werden, da sich beispielsweise die Fahrgeräusche von Pkws und Lkws wesentlich unterscheiden und feststehende Objekte, wie z.B. Leitplanken keinerlei Geräusche verursachen.In an advantageous variant of the inventive method the ambient noise recorded with the help of at least one directional microphone. In this case can the detected acoustic signal of a direction in the area assigned to the vehicle or a surrounding segment. This proves to be particularly advantageous if the driver information system additionally also includes at least one distance-sensing sensor the objects in this surrounding segment covered by the directional microphone have the vehicle detected. That captured by the directional microphone acoustic signal can then be used for classification in an advantageous manner the objects detected by the distance-sensing sensor because, for example, the driving noise of cars and trucks is significant distinguish and fixed objects, such as No guardrails Sounds cause.
Je nach Art der Auswertung des erfassten akustischen Signals können auch andere bzw. noch weitere Informationen aus den Umgebungsgeräuschen gewonnen werden. So kann beispielsweise aufgrund einer Frequenzverschiebung eine sich ändernde Relativgeschwindigkeit eines Objekts in Bezug auf das Fahrzeug ermit telt werden. Des Weiteren können z.B. auch das Hupen eines anderen Fahrzeugs und die Sirenen von Polizei-, Krankenwagen- und Feuerwehrfahrzeugen erkannt werden und als Indiz für eine drohende Gefahr ausgewertet werden.Depending on the type of evaluation of the recorded acoustic Signal can other or even more information obtained from the ambient noise become. For example, due to a frequency shift a changing Relative speed of an object with respect to the vehicle determined become. Furthermore, you can e.g. also the horn of another vehicle and the sirens from Police, ambulance and fire engines are recognized and as an indication of an impending danger can be evaluated.
