Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Steuerung von optischen und/oder akustischen Informationen in einem Kraftfahrzeug.The invention relates to a method and a device for controlling optical and / or acoustic information in a motor vehicle.

In modernen Kraftfahrzeugen existieren eine Vielzahl von Komponenten, die optische und akustische Informationen erzeugen, die den Kraftfahrzeugführer in seiner Konzentration auf den Straßenverkehr ablenken können. Neben dem klassischen Radio mit seinen Verkehrsnachrichten sind dies insbesondere Navigationssysteme mit optischer oder akustischer Zielführung, Autotelefone und Multifunktions-Anzeigeeinheiten mit wechselnden grafischen Oberflächen.In modern motor vehicles exist a variety of components that generate visual and audible information that can distract the motor vehicle driver in its concentration on the road. In addition to the classic radio with its traffic news, these are in particular navigation systems with optical or acoustic route guidance, car telephones and multifunction display units with changing graphic surfaces.

Aus der DE 199 04 066 A1 ist ein Verfahren zur Ermittlung von fahrsituationsabhängigen Parametern und Anzeige derselben auf einem Anzeigemittel bekannt, wobei eine Mehrzahl von fahrsituationsabhängigen Parametern ermittelt wird, wobei aus einer korrelierenden Bewertung aller ermittelten Parameter miteinander ein einziger Situationswert bestimmt wird, welcher zur Anzeige kommt. Vorzugsweise werden als Parameter die Drehzahl und/oder die Geschwindigkeit und/oder Lenkbewegungen bewertet. Weiter vorzugsweise können farbliche und/oder tonale Signale generiert werden, wenn der aktuelle Situationswert einen Grenzwert oder einen Grenzbereich erreicht, um so auf das Erreichen des Grenzwertes hinzuweisen.From the DE 199 04 066 A1 a method is known for ascertaining driving-situation-dependent parameters and displaying them on a display means, wherein a plurality of driving-situation-dependent parameters is determined, wherein from a correlating evaluation of all determined parameters a single situation value is determined which is displayed. Preferably, the speed and / or the speed and / or steering movements are evaluated as parameters. Further preferably, color and / or tonal signals can be generated when the current situation value reaches a limit value or a limit range, so as to indicate that the limit value has been reached.

Aus der DE 38 28 634 A1 ist eine akustische Informations- und Warnvorrichtung in einem Fahrzeug bekannt, mit einem Lautsprecher, welcher sowohl von einem Audio-Gerät als auch vom Ausgangsverstärker wenigstens einer Einrichtung zur Aufbereitung von hörbarer Information oder von hörbaren Warnsignalen ansteuerbar ist.From the DE 38 28 634 A1 an acoustic information and warning device in a vehicle is known, with a loudspeaker, which is controllable by both an audio device and the output amplifier of at least one device for preparing audible information or audible warning signals.

Der Erfindung liegt daher das technische Problem zugrunde, ein Verfahren und eine Vorrichtung zur Steuerung von akustischen Informationen in einem Kraftfahrzeug zu schaffen, mittels derer ein Kraftfahrzeugführer weniger stark vom Verkehrsgeschehen abgelenkt wird.The invention is therefore the technical problem of providing a method and apparatus for controlling acoustic information in a motor vehicle, by means of which a motor vehicle driver is less distracted from the traffic.

Die Lösung des technischen Problems ergibt sich durch die Gegenstände mit den Merkmalen der Patentansprüche 1 und 3. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The solution of the technical problem results from the objects with the features of claims 1 and 3. Further advantageous embodiments emerge from the dependent claims.

Hierzu wird mittels der Daten mindestens eines Fahrzeugzustandssensors eine Fahrsituationserkennung durchgeführt, wobei die erfasste Fahrsituation klassifiziert wird und in Abhängigkeit von der Klassifizierung die akustischen Informationen ausgeben, verzögert, zwischengespeichert oder unterdrückt werden. Die Klassifikation stuft dabei eine Fahrsituation mindestens als kritisch oder unkritisch ein, wobei bei einer als unkritisch eingestuften Fahrsituation die akustischen Informationen der elektrischen Komponente Autotelefon und/oder Radio ausgegeben werden und bei einer als kritisch eingestuften Fahrsituation die akustischen Informationen der elektrischen Komponente verzögert, zwischengespeichert oder unterdrückt werden. Dadurch wird gewährleistet, dass der Kraftfahrzeugführer in Situationen großer Konzentration wie beispielsweise sehr schnelle Autobahnfahrten, starke Bremsvorgänge oder zu dichtes Auffahren des rückwärtigen Verkehrs bzw. zu dichtes Auffahren auf ein vorausfahrendes Kraftfahrzeug nicht kurzzeitig mit fatalen Folgen abgelenkt wird. Vielmehr werden die Informationen dem Kraftfahrzeugführer situationsgerecht aufbereitet.For this purpose, a driving situation recognition is carried out by means of the data of at least one vehicle condition sensor, wherein the detected driving situation is classified and the acoustic information is output, delayed, buffered or suppressed depending on the classification. The classification classifies a driving situation as at least critical or uncritical, wherein the acoustic information of the electrical component car phone and / or radio are output in a classified as uncritical driving situation and delayed in a classified as critical driving situation, the acoustic information of the electrical component, cached or be suppressed. This ensures that the motor vehicle driver in situations of high concentration such as very fast highway driving, heavy braking or too close driving up the rear traffic or too close to a leading vehicle is not briefly distracted with fatal consequences. Rather, the information to the motor vehicle driver prepared in accordance with the situation.

Dabei ist der Fahrzeugzustandssensor als Lenkwinkelsensor ausgebildet.In this case, the vehicle condition sensor is designed as a steering angle sensor.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt ein schematisches Blockschaltbild einer Vorrichtung zur Steuerung von optischen und/oder akustischen Informationen in einem Kraftfahrzeug.The invention will be explained in more detail below with reference to a preferred embodiment. The single FIGURE shows a schematic block diagram of a device for controlling optical and / or acoustic information in a motor vehicle.

Die Vorrichtung 1 umfasst ein Bremsassistenz-System 2, ein zentrales Steuergerät 3, ein integriertes Abstands-Geschwindigkeits-Regelungssystem 4, ein Autotelefon 5, eine Multifunktions-Anzeigeeinheit 6, einen Lautsprecher 7, ein Navigationssystem 8, ein Radio 9 mit integriertem Speicher 10 und eine RF-Schnittstelle 11, die alle über eine Busstruktur 12 miteinander verbunden sind.The device 1 includes a brake assist system 2 , a central control unit 3 , an integrated distance-speed control system 4 , a car phone 5 , a multifunction display unit 6 , a speaker 7 , a navigation system 8th , a radio 9 with integrated memory 10 and an RF interface 11 all over a bus structure 12 connected to each other.

In einem ersten Schritt erfasst das zentrale Steuergerät 3 die aktuellen Daten von dem Bremsassistenz-System 2, dem Abstands-Geschwindigkeits-Regelungssystem 4 und von dem Navigationssystem 8. So kann beispielsweise anhand der Daten des Navigationssystems 8 ermittelt werden, wo sich das Kraftfahrzeug aktuell befindet, einschließlich des Straßentyps. Des weiteren kann anhand der berechneten Zielroute sowie der vorhandenen Datenbasis ermittelt werden, ob aktuell beispielsweise häufig Kurven durchfahren werden müssen oder häufig Richtungsänderungen erfolgen.In a first step, the central control unit detects 3 the current data from the brake assist system 2 , the distance-speed control system 4 and from the navigation system 8th , So, for example, based on the data of the navigation system 8th be determined where the motor vehicle is currently located, including the road type. Furthermore, it can be determined on the basis of the calculated target route as well as the existing database whether, for example, curves often have to be traveled through or frequent changes of direction take place.

Anhand der Daten des Abstands-Geschwindigkeits-Regelungssystems 4 kann der vorausfahrende und rückwärtige Verkehr eingestuft werden und die Entwicklung der Eigengeschwindigkeit abgeschätzt werden. Aufgrund der Daten des Bremsassistenz-Systems 2 erkennt das zentrale Steuergerät 3, ob aktuell Bremsmanöver erfolgen und wie ausgeprägt diese sind.Based on the data of the distance-speed control system 4 the forward and backward traffic can be classified and the development of the own speed can be estimated. Based on the data of the brake assist system 2 recognizes the central control unit 3 , whether current braking maneuvers and how pronounced they are.

Diese erfasste Verkehrssituation wird von dem zentralen Steuergerät klassifiziert. Diese Klassifizierung kann im einfachsten Fall darin bestehen, dass die Fahrsituation als kritisch oder unkritisch eingestuft wird. Es sind jedoch auch vielstufige Klassifikationen denkbar. Wird nun die erfasste Verkehrssituation als kritisch erfasst, beispielsweise weil ein Fahrtrichtungswechsel unmittelbar bevorsteht oder das Kraftfahrzeug gerade stark beschleunigt oder verzögert wird, so werden akustische oder optische Informationen modifiziert dem Kraftfahrzeugführer zur Verfügung gestellt, wobei die Art der Modifikation auch nutzerspezifisch vorgebbar sein kann.This detected traffic situation is classified by the central control unit. In the simplest case, this classification can be that the driving situation is classified as critical or uncritical. However, also multi-level classifications are conceivable. Now, if the detected traffic situation is detected as critical, for example, because a change of direction is imminent or the motor vehicle is currently greatly accelerated or decelerated, then acoustic or visual information is modified the motor vehicle driver made available, the type of modification can also be specified user-specific.

Bei einem Telefonanruf kann dieser beispielsweise in eine Mailbox umgeleitet werden, wobei gegebenenfalls ein erläuternder Zusatz für den Anrufer erfolgt. Alternativ kann das Telefon stumm geschaltet werden, wobei dann die Nummer des Anrufers zwischengespeichert wird und automatisch zurückgerufen wird, wenn die Fahrtsituation nicht mehr als kritisch klassifiziert wird. Des weiteren kann die Klingelzeit verlängert werden, falls aufgrund der Datenbasis kurzfristig zu erwarten ist, dass die Verkehrssituation nicht mehr kritisch ist, beispielsweise weil dann der Fahrtrichtungswechsel vollzogen ist. Alternativ kann der Anrufer eine Rückmeldung erhalten, dass dieser nach einer gewissen Zeit noch einmal anrufen soll, wobei die Zeit mit Hilfe der geschätzten Reisezeit entlang der Fahrtroute bis zu Fahrtroutenanteilen mit geringer Abbiegehäufigkeit berechnet wird. Verkehrsdurchsagen des Radios 9 können im Speicher 10 zwischengespeichert werden. Dabei kann die Dringlichkeit der Verkehrsmeldung anhand der berechneten Fahrtroute abgeschätzt werden. Die Verkehrsmeldung bleibt dann solange im Speicher, bis die Verkehrssituation nicht mehr als kritisch oder Verkehrsmeldung oder die Verkehrsmeldung aufgrund der aktuellen Position dringlich wird.In the case of a telephone call, this can for example be diverted to a mailbox, with an explanatory addition being made for the caller if necessary. Alternatively, the phone can be muted, then the number of the caller is cached and automatically recalled when the driving situation is no longer classified as critical. Furthermore, the ringing time can be extended if, on the basis of the database, it is to be expected at short notice that the traffic situation is no longer critical, for example because the direction of travel has then been changed. Alternatively, the caller may receive a response that he should call again after a certain time, the time is calculated using the estimated travel time along the route to low-turn travel route shares. Traffic announcements of the radio 9 can in memory 10 be cached. The urgency of the traffic message can be estimated on the basis of the calculated route. The traffic message then remains in the memory until the traffic situation is no longer critical or traffic report or the traffic report due to the current position is urgent.

Zur verbesserten Wahrnehmung der akustischen Information, insbesondere der Verkehrsmeldungen, kann zusätzlich vorgesehen sein, dass mittels eines Mikrofons die Innengeräusche überwacht werden und die zwischengespeicherte Verkehrsmeldung in einer Gesprächslücke ausgegeben wird.For improved perception of the acoustic information, in particular the traffic reports, it may additionally be provided that the interior noise is monitored by means of a microphone and the cached traffic message is output in a gap in the conversation.

Weiter kann vorgesehen sein, dass Audiostücke mitgeschnitten werden und verzögert angegeben werden. Ist beispielsweise für das zentrale Steuergerät 3 erkennbar, dass ein Fahrtrichtungshinweis des Navigationssystems 8 in eine Nachrichtensendung fällt, so kann das Radio 9 stumm geschaltet werden, so dass sich der Kraftfahrzeugführer auf die optische und/oder akustische Ausgabe des Navigationssystems 8 über die Multifunktions-Anzeigeeinheit 6 und/oder den Lautsprecher 7 konzentrieren kann. In der Zwischenzeit wird die Nachrichtensendung im Speicher 10 zwischengespeichert und in unkritischen Fahrtsituationen ausgegeben.Furthermore, it can be provided that audio pieces are recorded and delayed. Is for example for the central control unit 3 recognizable that a direction indicator of the navigation system 8th in a newscast, so can the radio 9 be muted, so that the motor vehicle driver on the visual and / or acoustic output of the navigation system 8th via the multifunction display unit 6 and / or the speaker 7 can concentrate. In the meantime, the news program is in memory 10 cached and issued in uncritical driving situations.

Änderungen der grafischen Oberfläche der Multifunktions-Anzeigeeinheit 6 aufgrund von Funktionsänderungen sollten in kritischen Fahrsituationen soweit als möglich unterdrückt werden, um den Kraftfahrzeugführer nicht in seiner Konzentration zu stören.Changes to the graphical interface of the multifunction display unit 6 due to functional changes should be suppressed as far as possible in critical driving situations, so as not to disturb the motor vehicle driver in its concentration.
