Abstract

A number of different functions are available in a road vehicle system and are displayed as a menu on a screen. Selection of specific functions is made with the use of a push button input that causes a cursor to move down the menu. On activation of the push button, only the menus and/or functions displayed are selected which have an acoustic selection- or input mode.

Description

Die Erfindung bezieht sich auf eine Anzeige- und Bedienvorrichtung mit den Merk­ malen des Oberbegriffs von Patentanspruch 1.The invention relates to a display and control device with the Merk paint the preamble of claim 1.

Eine derartige Vorrichtung ist aus der DE 38 36 555 A bekannt. Daneben ist es bei Fahrzeugen auch bekannt, Eingaben akustisch vorzunehmen (vgl. US 5,410,739). Insbesondere für den unkundigen Fahrzeugbenutzer ist es schwierig, die Menüs und/oder Funktionen eines Fahrzeugs auszuwählen, bei denen tatsächlich eine akustische Bedienmöglichkeit besteht.Such a device is known from DE 38 36 555 A. It is also next to Vehicles are also known to make inputs acoustically (cf. US 5,410,739). The menus are particularly difficult for inexperienced vehicle users and / or select functions of a vehicle that actually have a there is acoustic control.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genann­ ten Art zu schaffen, bei der auch dem unkundigen Fahrzeugbenutzer auf signifi­ kante Weise das Menü bzw. die Funktion deutlich gemacht wird, bei dem eine akustische Bedienmöglichkeit besteht.The invention has for its object a device of the aforementioned ten way to create, in which even the unskilled vehicle user on signifi edge of the menu or the function is made clear in which a there is acoustic control.

Die Erfindung löst diese Aufgabe durch die Merkmale des Patentanspruchs 1.The invention solves this problem by the features of claim 1.

Durch die optische Hervorhebung der Menüs bzw. Funktionen in Verbindung mit der Betätigung des Druckschalters wird dem Fahrzeugbenutzer diese Möglichkeit besonders deutlich gemacht. Im Gegensatz beispielsweise zu einem selbsttätigen Hervorheben der Menüs bzw. Funktionen dann, wenn der Fahrzeugbenutzer einen entsprechenden Befehl ausspricht, bietet die Verwendung des Druckschalters ei­ nen Schutz vor einer unbeabsichtigten Auslösung dieser Hervorhebung. Dadurch wird eine Irritierung des Fahrzeugbenutzers, wie sie ansonsten möglich ist, sicher vermieden. By optically highlighting the menus or functions in connection with Pressing the pressure switch gives the vehicle user this option made particularly clear. In contrast, for example, to an automatic one Highlight the menus or functions when the vehicle user pronounces the corresponding command, offers the use of the pressure switch ei protection against accidental triggering of this highlighting. Thereby will irritate the vehicle user, as is otherwise possible avoided.  

In den weiteren Patentansprüchen sind vorteilhafte Ausgestaltungen der Erfindung dargestellt. Anhand der Zeichnung wird die Erfindung und die besonders vorteilhaf­ ten Ausgestaltungen weiter erläutert.Advantageous refinements of the invention are in the further patent claims shown. Based on the drawing, the invention and the particularly advantageous th configurations further explained.

In der Figur sind in zwei Diagrammen (Fig. 1 und Fig. 2) Ausführungsformen der Erfindung gezeigt.In the figure (Fig. 1 and Fig. 2) embodiments of the invention are shown in two diagrams.

Bei der Ausführungsform von Fig. 1 sind auf einem Bildschirm 1 beispielhaft eine Reihe von Menüs dargestellt, die über eine manuelle, nicht dargestellte Bedienein­ richtung, wie beispielsweise eine Tastatur oder einen Druck-Dreh-Schalter (DE 38 36 555A) auswählbar sind. Ferner ist in Fig. 1 ein Druckschalter 2 gezeigt, bei dem es sich um einen sogenannten Push to Talk-Schalter handelt. Der Druckschalter 2 kann zu einem beliebigen Zeitpunkt durch den Fahrzeugbenutzer betätigt werden. Nach der Betätigung des Druckschalters 2 verändert sich der Inhalt des Bild­ schirms 1 in der Weise, wie sie anhand des dann geänderten Bildschirminhalts 1' dargestellt ist. Neben den bereits ursprünglich vorhandenen Menüpunkten wie Au­ dio, Klima, Navigation, Bordcomputer und Telefon ist nun neben den Menüs, für die eine optische Bedien- bzw. Auswahlmöglichkeit besteht, eine optische Hervor­ hebung dargestellt. Es kann sich dabei um einen Pfeil 3 oder aber auch, nicht dar­ gestellt, um ein anderes Symbol, einen Farbumschlag oder ein ähnliches Mittel handeln. Der Fahrzeugbenutzer erhält damit nach Betätigen des Druckschalters 2 die Information, daß sich das Menü Navigation und das Menü Telefon gegenüber den Menüs Audio, Klima und Bordcomputer durch eine akustische Eingabe- bzw. Auswahlmöglichkeit unterscheiden. Er kann nun über die Bedieneinrichtung bei­ spielsweise das Menü Navigation ansteuern und dort durch einen entsprechenden Sprachbefehl das Reiseziel eingeben. Die gesamte Steuerung des Eingabevor­ gangs kann dabei über eine entsprechende manuelle Bedienmöglichkeit oder aber auch auf akustischem Wege erfolgen.In the embodiment of Fig. 1, a series of menus are shown as an example on a screen 1 , which can be selected via a manual device (not shown), such as a keyboard or a push-turn switch (DE 38 36 555A). Furthermore, a pressure switch 2 is shown in FIG. 1, which is a so-called push to talk switch. The pressure switch 2 can be operated by the vehicle user at any time. After actuation of the pressure switch 2 , the content of the screen 1 changes in the way it is shown on the basis of the then changed screen content 1 '. In addition to the originally existing menu items such as audio, air conditioning, navigation, on-board computer and telephone, an optical highlight is now shown in addition to the menus for which there is an optical operating or selection option. It can be an arrow 3 or, not shown, another symbol, a color change or a similar means. The vehicle user thus receives the information after actuation of the pressure switch 2 that the navigation menu and the telephone menu differ from the audio, air conditioning and on-board computer menus by an acoustic input or selection option. He can now, for example, control the navigation menu via the operating device and enter the travel destination there by means of a corresponding voice command. The entire control of the input process can take place via a corresponding manual operating option or also acoustically.

Zusätzlich ist in Fig. 2 eine weitere Ausführungsform der Erfindung gezeigt. Nach dem Betätigen des Druckschalters 2 erscheint auf dem Bildschirm, der nunmehr mit 1'' bezeichnet ist, neben den Menüpunkten mit akustischer Bedien- und Einga­ bemöglichkeit (Navigation und Telefon) in einem eingeblendeten Fenster weitere Menüs bzw. Funktionen mit akustischer Eingabe- bzw. Bedienmöglichkeit. In der dargestellten Ausführungsform handelt es sich dabei um einen CD-Player (CD), einen Kassettenrecorder (Tape) und ein Radiogerät (FM), sämtlich nicht darge­ stellt.In addition, a further embodiment of the invention is shown in FIG. 2. After pressing the pushbutton 2 , the menu, which is now labeled 1 '', shows, in addition to the menu items with acoustic operating and input options (navigation and telephone), additional menus or functions with acoustic input or Operating possibility. In the illustrated embodiment, this is a CD player (CD), a cassette recorder (tape) and a radio (FM), all of which are not shown.

Die mit den Bildschirminhalt 1' und 1'' versehene Information über akustische Ein­ gabe- und Bedienmöglichkeiten kann nach Betätigen der Push-to-Talk-Taste 2 ständig oder aber zeitlich begrenzt, beispielsweise für einen Zeitraum von 10 Se­ kunden wiedergegeben werden. In letzterem Fall wird nach Ablauf dieser Zeit, so­ fern keine Auswahl eines Menüs bzw. eine Funktion bis dahin erfolgt ist, der ur­ sprüngliche Bildschirminhalt 1 erneut wiedergegeben.The information on acoustic input and operating options provided with the screen contents 1 'and 1 ''can be reproduced continuously or for a limited time, for example for a period of 10 seconds, after the push-to-talk key 2 has been pressed. In the latter case, after this time has elapsed, unless a menu or a function has been selected until then, the original screen content 1 is displayed again.

Auf diese Weise wird die Nutzung bzw. das Erlernen der Spracheingabe deutlich erleichtert.In this way, the use or learning of voice input becomes clear facilitated.
