Description
Freisprechanlage für ein MobiltelefonHands-free system for a mobile phone
Die Erfindung betrifft eine Freisprechanlage für ein Mobiltelefon gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a hands-free system for a mobile phone according to the preamble of claim 1.
Derartige Anlagen sind in Kraftfahrzeugen üblich, um die Ablenkung des Fahrzeugführers durch die Bedienung des Mobiltelefons möglichst gering zu halten. Sie sind entweder werkseitig in das Bordnetz integriert (gegebenenfalls unter Mitverwendung des Bordradios) oder als Nachrüstsätze erhältlich. Allen bisherigen Systemen ist dabei der Nachteil gemeinsam, daß die Bedienung der Anlage mit Hilfe der Tastatur des Mo- biltelefons (allgemein als "Handy" bezeichnet) erfolgt. Diese Tastatur ist naturgemäß klein und schwer ablesbar, so daß zu ihrer Bedienung eine erhebliche Konzentration erforderlich ist. Dies ist ein wesentlicher Nachteil für den Fahrzeugführer. Hinzu kommt bei Nachrüstsätzen, daß die Ergonomie der Anlage, d.h. die Zuordnung des Mobiltelefons zum Sicht- und Griffbereich des Fahrzeugführers , meist nicht optimal gestaltet werden kann.Systems of this type are common in motor vehicles in order to keep the distraction of the vehicle driver as low as possible by operating the mobile telephone. They are either integrated into the vehicle electrical system at the factory (if necessary also using the on-board radio) or available as retrofit kits. All previous systems have the disadvantage in common that the system is operated using the keypad of the mobile telephone (generally referred to as "cell phone"). This keyboard is naturally small and difficult to read, so that a considerable concentration is required to operate it. This is a major disadvantage for the driver. In addition, in the case of retrofit kits, the ergonomics of the system, ie the assignment of the mobile phone to the view and Grip area of the driver, usually can not be optimally designed.
Aufgabe der vorliegenden Erfindung ist es daher, die Bedienbarkeit von Freisprechanlagen für Mobiltelefone zu vereinfachen und zu verbessern, ein (auch optisch) optimales Integrationssystem für Freisprechanlagen in Fahrzeugen anzugeben, und dabei die dem Mobiltelefon innewohnenden Anwendungsmöglichkeiten mehr als bisher üblich für eine erweiterte Kommunikation zu nutzen.The object of the present invention is therefore to simplify and improve the usability of hands-free systems for mobile telephones, to provide an (also optically) optimal integration system for hands-free systems in vehicles, and to use the mobile phone's inherent application options more than previously usual for advanced communication .
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Die Ansprüche 2 bis 13 geben vorteilhafte Weiterbildungen der erfin- dungsgemäßen Freisprechanlage an.This object is achieved by the features of the characterizing part of claim 1. Claims 2 to 13 indicate advantageous developments of the hands-free system according to the invention.
Dadurch, daß das Mobiltelefon eine zusätzliche Kontaktvorrichtung besitzt, mit deren Hilfe es mit einer räumlich getrennten, in der Freisprechanlage instal- lierten Tastatur (Parallel-Tastatur) elektrisch verbindbar ist, wobei die Parallel-Tastatur und die Tastatur des Mobiltelefons zumindest teilweise identische Funktionen haben und die Parallel-Tastatur bei einer Verbindung mit der Kontaktvorrichtung parallel zur Tastatur des Mobiltelefons betreibbar ist, ergeben sich wesentliche Vorteile. Die Parallel-Tastatur kann wesentlich größer ausgeführt werden als die Miniatur-Tastatur des Mobiltelefons. Sie ist damit übersichtlicher, griffiger und erfordert somit bei weitem weniger Aufmerksamkeit bei ihrer Bedienung.Characterized in that the mobile phone has an additional contact device, by means of which it can be electrically connected to a spatially separate keyboard (parallel keyboard) installed in the hands-free system, the parallel keyboard and the keyboard of the mobile phone having at least partially identical functions and the parallel keyboard can be operated parallel to the keyboard of the mobile phone when connected to the contact device, there are significant advantages. The parallel keyboard can be made much larger than the miniature keyboard of the mobile phone. It is therefore clearer, easier to grip and therefore requires far less attention when operating it.
Weiterhin kann das Mobiltelefon außerhalb des Sicht- und Griffbereichs des Fahrzeugführers untergebracht werden, wodurch kein Platz benötigt wird, der besser für andere Cockpitelemente genutzt werden kann. Schließlich ermöglicht die räumliche Trennung von Mobiltelefon und Parallel-Tastatur ein verstecktes Unterbringen des Mobiltelefons, was sowohl der Innen- raumoptik des Fahrzeugs als auch der Übersichtlichkeit der Bedienelemente zugute kommt.Furthermore, the mobile phone can be accommodated outside the driver's field of vision and grip, which means that no space is required that can be better used for other cockpit elements. Finally, the spatial separation of Mobile phone and parallel keyboard hide the mobile phone, which benefits both the interior appearance of the vehicle and the clarity of the controls.
Vorteilhafterweise sind die zusätzlichen Kontaktvorrichtungen, die zum Anschluß der Parallel-Tastatur benötigt werden, verdrahtete Steckverbindungen. Die Ausrüstung der Mobiltelefone hiermit verursacht wenig Mehraufwand, da sie ohnehin mit Steckverbindungen zum Anschluß an herkömmliche Freisprechanlagen versehen sind.Advantageously, the additional contact devices that are required to connect the parallel keyboard are wired plug connections. The equipment of the mobile phones hereby causes little additional effort, since they are provided with plug connections for connection to conventional hands-free systems anyway.
Wenn die Freisprechanlage ein Fax-Modem besitzt, kön- nen Texte empfangen werden. Dabei ist es zweckmäßig, wenn diese Fax-Modemkarte bereits im Mobiltelefon integriert ist, ohne daß dies aber zwingend notwendig ist; eine der Freisprechanlage zugeordnete Fax-Modemkarte ist ebenso möglich. Die Textwiedergabe kann dabei über ein Display erfolgen, das der Parallel- Tastatur zugeordnet ist; dieses kann ein vorhandenes Bordnetz-Display sein, das im allgemeinen im besten Sichtbereich des Fahrzeugführers angeordnet ist. Die Parallel-Tastatur ist bei Zuordnung einer Fax-Modem- karte zur Freisprechanlage für die Eingabe von (aussendbaren) Texten vorbereitet, wobei diese Texte ebenfalls in den jeweiligen Displays angezeigt werden. Ohne wesentlichen Mehraufwand kann die Freisprechanlage auch mit einem Anschluß für einen ( obi- len) Plotter versehen werden, mit dem die Faxtexte ausgedruckt werden können. Auf diese Weise läßt sich die Freisprechanlage zu einem universellen Kommunikationssystem erweitern, das bei einer einfachen Grundausrüstung, die im Fahrzeug werkseitig vorbereitet sein kann, durch entsprechende Steckkarten schrittweise nach Bedarf erweiterbar ist.If the hands-free system has a fax modem, texts can be received. It is useful if this fax modem card is already integrated in the mobile phone, but this is not absolutely necessary; a fax modem card assigned to the hands-free system is also possible. The text can be reproduced on a display that is assigned to the parallel keyboard; this can be an existing on-board electrical system display, which is generally arranged in the driver's best viewing area. When a fax modem card is assigned to the hands-free system, the parallel keyboard is prepared for the input of (sendable) texts, which texts are also shown in the respective displays. The hands-free system can also be provided with a connection for an (obile) plotter with which the fax texts can be printed out without any significant additional effort. In this way, the hands-free system can be expanded to a universal communication system, which, with simple basic equipment, is prepared in the vehicle at the factory can be gradually expanded by appropriate plug-in cards as needed.
Die räumliche Trennung von Mobiltelefon und Parallel- Tastatur ermöglicht es, diese im optimalen Sicht- und Griffbereich des Fahrzeugführers anzuordnen. Ist diese Tastatur schwenkbar, und zwar sowohl um eine im wesentlichen horizontale Achse als auch bei Bedarf zusätzlich um eine näherungsweise vertikale Achse, so lassen sich Sicht- und Bedienbarkeit der Parallel- Tastatur nicht nur für den Fahrzeugführer sondern auch für einen Beifahrer verbessern und optimieren.The spatial separation of the mobile phone and parallel keyboard makes it possible to arrange them in the driver's optimal viewing and grip area. If this keyboard can be swiveled, both about an essentially horizontal axis and, if necessary, additionally about an approximately vertical axis, the visibility and operability of the parallel keyboard can be improved and optimized not only for the vehicle driver but also for a passenger.
Die räumliche Trennung von Mobiltelefon und Parallel- Tastatur ermöglicht weiterhin, das Mobiltelefon optisch zu "verstecken" und es dabei optimal zu schützen. Dabei ist sowohl die Verbindung des Mobiltelefons mit der Freisprechanlage in einer bündig mit der Umgebung einschiebbaren Schublade möglich als auch die Verbindung und Unterbringung in einem mit einer Klappe abdeckbaren Fach. In beiden Fällen ist das Mobiltelefon sowohl "unsichtbar" als auch optimal geschützt, zumal wenn es dabei durch die Verwendung von schützenden Polstern, zum Beispiel Schaumstoff, stoßgesichert ist.The spatial separation of the mobile phone and the parallel keyboard also enables the mobile phone to be "hidden" and optimally protected. Both the connection of the mobile phone with the hands-free system is possible in a drawer that can be inserted flush with the surroundings, as well as the connection and accommodation in a compartment that can be covered with a flap. In both cases, the mobile phone is both "invisible" and optimally protected, especially if it is protected against shock by the use of protective pads, such as foam.
Wird die Freisprechanlage nicht genutzt, so kann es zweckmäßig sein, wenn zumindest ihre Parallel-Tastatur mit einer der Stilistik des Innenraums angepaßten Klappe abdeckbar ist. Die Tastatur ist so gut geschützt, wenn sie nicht benötigt wird. Wird eine Fahrzeug-Serie durchgehend so für eine Mobiltelefon- Anlage vorbereitet, so ist eine Abdeckung der vorgesehenen Einbauorte besonders zweckmäßig, da nicht je- der Fahrzeugbenutzer ein Mobiltelefon verwenden wird. In Verbindung mit der Schwenkbarkeit der Parallel- Tastatur ist der Bereich der Mittelkonsole, vorzugsweise der Ubergangsbereich von der Mittelkonsole zur Schalttafel, ein Bereich, in dem Sicht- und Bedien- barkeit optimal sind. In diesem Bereich kann außerdem auch das Mobiltelefon, beispielsweise in einer Schublade, einfach untergebracht werden, so daß eine außerordentlich kompakte Ausführung der Freisprechanlage realisierbar ist. Es ist aber auch möglich, die Parallel-Tastatur gesondert steckbar auszubilden.If the hands-free system is not used, it can be useful if at least its parallel keyboard can be covered with a flap that is adapted to the style of the interior. The keyboard is so well protected when it is not needed. If a vehicle series is continuously prepared for a mobile phone system, covering the intended installation locations is particularly expedient, since not every vehicle user will use a mobile phone. In connection with the pivotability of the parallel keyboard, the area of the center console, preferably the transition area from the center console to the control panel, is an area in which visibility and operability are optimal. In this area, the mobile phone can also be easily accommodated, for example in a drawer, so that an extremely compact design of the hands-free system can be implemented. However, it is also possible to design the parallel keyboard to be separately pluggable.
Eine serienmäßige Vorbereitung der Fahrzeuge brauchte dann keine Parallel-Tastatur zu enthalten, diese könnte - beispielsweise als biegsamer "Schwanenhals" - im Sichtbereich des Fahrzeugführers bei Be- darf eingesteckt werden. In jedem Fall ist es zweckmäßig, die Parallel-Tastatur beleuchtbar auszuführen, um die Sicht- und Bedienbarkeit zu optimieren, vor allem dann, wenn die Parallel-Tastatur im "Schattenbereich" der Mittelkonsole angeordnet ist.Standard preparation of the vehicles then did not need to include a parallel keyboard, which could be inserted - for example as a flexible "gooseneck" - in the driver's field of vision if necessary. In any case, it is expedient to design the parallel keyboard to be illuminated, in order to optimize the visibility and usability, especially when the parallel keyboard is arranged in the "shadow area" of the center console.
Die Neuerung wird nunmehr anhand der Figur näher erläutert.The innovation is now explained in more detail with reference to the figure.
Die Figur zeigt in (vereinfachter) perspektivischer Darstellung eine Ausführungs orm der Erfindung. Die Parallel-Tastatur 2 ist im Ubergangsbereich 3 ' zwischen der Mittelkonsole 3 und der Schalttafel 5 angeordnet und in Pfeilrichtung ausschwenkbar. Sie besitzt außer den Funktionstasten (nicht extra gekenn- zeichnet aus Gründen der Übersichtlichkeit) dasThe figure shows a (simplified) perspective view of an embodiment of the invention. The parallel keyboard 2 is arranged in the transition area 3 'between the center console 3 and the control panel 5 and can be swung out in the direction of the arrow. In addition to the function keys (not specially marked for reasons of clarity), it has this
Display 2'. Außerhalb der Parallel-Tastatur 2 können weitere, beispielsweise besonders große Funktionstasten 2" angeordnet sein. Das Mobiltelefon (nicht dargestellt) ist in dem Schiebefach 1 untergebracht und mit Hilfe von Steckverbindungen an die Freisprechan- läge angeschlossen. Bei eingeschobenem Schubfach 1 und eingeklappter Parallel-Tastatur 2 sind diese durch die in Pfeilrichtung klappbare und in aufgeklapptem Zustand in Richtung des Doppelpfeiles in die Schalttafel 5 einschiebbar Klappe 4 verdeckbar, wobei die Klappe 4 die Freisprechanlage mit Hilfe des Schlosses 6 gegen unbefugte Benutzung sichert.Display 2 '. Additional, for example particularly large, function keys 2 ″ can be arranged outside the parallel keyboard 2. The mobile telephone (not shown) is accommodated in the sliding compartment 1 and is connected to the hands-free would be connected. When the drawer 1 is pushed in and the parallel keyboard 2 is folded in, these can be hidden by the foldable in the direction of the arrow and in the open state in the direction of the double arrow in the control panel 5 flap 4, the flap 4 securing the hands-free system with the help of the lock 6 against unauthorized use.
Erfindungsgemäße Freisprechanlagen können werkseitig unterschiedlich weit vorbereitet sein. Eine komplette Vorinstallation, bei der nur noch das Mobiltelefon eingelegt werden muß, sind ebenso möglich wie Teilin- stallationen, bei denen wesentliche Elemente wie Parallel-Tastatur, Mikrofon, Verstärker und Lautspre- eher nachträglich, vorzugsweise durch einfache Steckverbindungen, nachrüstbar sind. Eine Abdeckklappe, beispielsweise die Klappe 4 in der Figur, einschiebbar oder auch entfernbar, kaschiert dabei die Einbauorte optisch einwandfrei, wenn der Einbau der Frei- Sprechanlage nicht gewünscht wird.Hands-free systems according to the invention can be prepared at different levels in the factory. A complete pre-installation, in which only the mobile phone has to be inserted, is also possible, as are partial installations in which essential elements such as parallel keyboard, microphone, amplifier and loudspeaker can be retrofitted, preferably using simple plug connections. A cover flap, for example flap 4 in the figure, which can be inserted or removed, conceals the installation locations in a visually perfect manner if the installation of the hands-free intercom system is not desired.
Die erfindungsgemäße Freisprechanlage ist vorzugsweise für Kraftfahrzeuge einsetzbar, ohne daß andere Einsatzmöglichkeiten zum Beispiel in Kränen, Bau a- schinen oder Fertigungsanlagen ausgeschlossen wären. The hands-free system according to the invention can preferably be used for motor vehicles without excluding other possible uses, for example in cranes, construction machines or production systems.
