The appts. includes a microprocessor module (7) generating control and processing signals, with an address bus (15) and a data bus (21). A RAM memory (9) holds data which is valid at a particular instant, whilst a permanent memory (8) holds descriptive vocabulary recorded to TMC standards for operation in a particular language. The microprocessors is connected to a voice synthesiser (20) with amplifier and loudspeaker (4,5) and a display screen (10).

Description

La présente invention concerne un appareil destiné à construire et délivrer des messages sur la base de codes numériques qui désignent chacun un élément de vocabulaire concernant une route qu'un utilisateur est susceptible de suivre, muni d'au moins deux portions de mémoire permanente de vocabulaire, chacune d'elles correspondant à une langue différente.The present invention relates to an apparatus for constructing and delivering messages on the basis of digital codes each designating a vocabulary element relating to a route that a user is likely to follow, provided with at least two portions of permanent vocabulary memory , each of which corresponds to a different language.

Un tel appareil est utilisé notamment dans le domaine des véhicules automobiles.Such a device is used in particular in the field of motor vehicles.

Elle concerne aussi un module de génération de messages, destiné à un appareil d'information routière, comportant ou associé à au moins deux portions de mémoire permanente de vocabulaire, chacune d'elles correspondant à une langue différente, module comportant des moyens pour construire des messages sur la base de codes numériques qui désignent chacun un élément de vocabulaire concernant une route qu'un utilisateur est susceptible de suivre.It also relates to a module for generating messages, intended for a traffic information device, comprising or associated with at least two portions of permanent vocabulary memory, each of them corresponding to a different language, module comprising means for constructing messages based on digital codes which each designate a vocabulary element relating to a route that a user is likely to follow.

Un tel module est destiné à être incorporé dans un appareil destiné à délivrer des messages.Such a module is intended to be incorporated into an apparatus intended to deliver messages.

Un appareil correspondant au préambule ci-dessus est connu du document JP-A-4_292100. L'appareil décrit dans ce document est un récepteur auto-radio apte à recevoir les émissions d'émetteurs dits RDS, récepteur qui possède plusieurs portions de mémoire permanente de vocabulaire, chacune d'elles correspondant à une langue différente, et choisit la mémoire correspondant à la langue du pays où se trouve le véhicule, pays qu'il connaît grâce aux codes dits PI reçus de la part de l'émetteur RDS.An apparatus corresponding to the above preamble is known from the document JP-A-4_292100. The device described in this document is an auto-radio receiver capable of receiving emissions from so-called RDS transmitters, a receiver which has several portions of permanent vocabulary memory, each of which corresponds to a different language, and chooses the corresponding memory the language of the country where the vehicle is located, a country which it knows thanks to so-called PI codes received from the RDS transmitter.

Lorsqu'un usager d'un véhicule automobile circule dans un pays étranger et qu'il désire exploiter des messages concernant la route qu'il va suivre, il risque néanmoins de subir une difficulté, que l'on peut illustrer par un exemple concret. Supposons que cet usager circule en Belgique et se dirige vers la France, et qu'un message qui l'intéresse d'entendre les messages en français, il entendra "Lille" mais, malheureusement pour lui, les panneaux routiers qu'il rencontre portent des indications en flamand, à savoir pour cette ville "Rijsel", qu'il risque donc de ne pas comprendre.When a user of a motor vehicle travels in a foreign country and wishes to use messages concerning the route he is going to follow, he nevertheless risks suffering a difficulty, which can be illustrated by a concrete example. Suppose that this user travels in Belgium and goes to France, and that a message that interests him to hear the messages in French, he will hear "Lille" but, unfortunately for him, the road signs which he meets carry indications in Flemish, namely for this city "Rijsel", which he therefore risks not understanding.

L'invention a entre autres pour but de répondre à ce problème.The invention aims inter alia to respond to this problem.

Un appareil selon l'invention est remarquable en ce qu'il est muni de moyens pour appeler, sur la base d'un code numérique, certains mots dans une portion de mémoire correspondant à une langue, puis dans une autre portion correspondant à une autre langue, de façon à afficher et/ou énoncer ce même mot successivement dans chacune des langues.An apparatus according to the invention is remarkable in that it is provided with means for calling, on the basis of a digital code, certain words in a portion of memory corresponding to a language, then in another portion corresponding to another language, so as to display and / or pronounce the same word successively in each of the languages.

De préférence l'appareil comporte des moyens pour appeler des éléments de messages concernant des éléments de vocabulaire courant dans une même portion de mémoire, et pour appeler des éléments de vocabulaire susceptibles d'apparaître sur des panneaux routiers successivement dans deux portions de mémoire correspondant chacune à une langue différente.Preferably, the apparatus includes means for calling up elements of messages relating to vocabulary elements running in the same portion of memory, and for calling up vocabulary elements capable of appearing on road signs successively in two portions of memory each corresponding to a different language.

Ainsi l'usager est à même de comprendre l'énoncé général d'un message tout en connaissant, en plus, la prononciation ou l'épellation, ou les deux, d'un mot particulier de la langue du pays traversé. La traduction dans la langue du pays traversé est réalisée par exemple pour les noms de lieux ou pour certaines indications routières particulières qu'il est utile de comprendre.Thus the user is able to understand the general statement of a message while knowing, in addition, the pronunciation or the spelling, or both, of a particular word of the language of the country crossed. The translation into the language of the country crossed is carried out for example for place names or for certain particular road indications which it is useful to understand.

Dans une variante l'appareil est muni de moyens pour appeler, sur la base d'un code numérique, un mot à afficher et/ou énoncer soit dans une portion de mémoire correspondant à une langue, soit dans une autre portion de mémoire correspondant à une autre langue, selon la nature de ce mot.In a variant, the apparatus is provided with means for calling, on the basis of a numerical code, a word to be displayed and / or speaking either in a portion of memory corresponding to a language, or in another portion of memory corresponding to another language, depending on the nature of the word.

De préférence il comporte des moyens pour appeler des éléments de messages concernant des éléments de vocabulaire courant dans une même portion de mémoire, et pour appeler des éléments de vocabulaire susceptibles d'apparaître sur des panneaux routiers dans une autre portion de mémoire correspondant à une autre langue.Preferably, it includes means for calling up elements of messages relating to elements of vocabulary current in the same portion of memory, and for calling up elements of vocabulary capable of appearing on road signs in another portion of memory corresponding to another language.

Ainsi un message est annoncé ou affiché dans la langue de l'usager sauf pour certains mots qui le sont dans la langue du pays traversé.Thus a message is announced or displayed in the language of the user except for certain words which are in the language of the country crossed.

Dans encore une autre variante, l'appareil est muni de moyens pour permettre à un usager de désigner un mot présent dans une portion de mémoire correspondant à une langue, de moyens pour appeler, sur la base du mot ainsi défini, un mot correspondant dans une autre portion de mémoire correspondant à une autre langue, et de moyens pour afficher et/ou énoncer ce dernier mot.In yet another variant, the apparatus is provided with means for enabling a user to designate a word present in a memory portion corresponding to a language, with means for calling, on the basis of the word thus defined, a corresponding word in another portion of memory corresponding to another language, and means for displaying and / or speaking this last word.

Ainsi l'usager peut, sur sa demande, connaître la traduction d'un mot qui l'intéresse.Thus the user can, on his request, know the translation of a word which interests him.

Dans un mode de réalisation particulier, l'appareil est un récepteur auto-radio destiné entre autres à recevoir et traiter un signal dit RDS-TMC qui comporte des signaux numériques contenant des messages routiers constitués des dits codes, récepteur muni de moyens pour sélectionner automatiquement une des portions de mémoire sur la base d'un code dit "PI".In a particular embodiment, the device is an auto-radio receiver intended inter alia to receive and process a so-called RDS-TMC signal which comprises digital signals containing traffic messages made up of said codes, receiver provided with means for automatically selecting one of the memory portions on the basis of a code called "PI".

Un module de génération de messages selon l'invention est remarquable en ce qu'il est muni de moyens pour appeler, sur la base d'un code numérique, certains mots dans une portion de mémoire correspondant à une langue, puis dans une autre portion correspondant à une autre langue, de façon à afficher et/ou énoncer ce même mot successivement dans chacune des langues.A message generation module according to the invention is remarkable in that it is provided with means for calling, on the basis of a digital code, certain words in a portion of memory corresponding to a language, then in another portion corresponding to another language, so as to display and / or pronounce the same word successively in each of the languages.

Un tel module comporte de préférence des moyens pour appeler des éléments de messages concernant des éléments de vocabulaire courant dans une même portion de mémoire, et pour appeler des éléments de vocabulaire susceptibles d'apparaître sur des panneaux routiers successivement dans deux portions de mémoire correspondant chacune à une langue différente.Such a module preferably comprises means for calling up elements of messages concerning elements of vocabulary current in the same portion of memory, and for calling up elements of vocabulary capable of appearing on road signs successively in two portions of memory each corresponding to a different language.

Dans un mode de réalisation particulier, un tel module est muni de moyens pour appeler, sur la base d'un code numérique, un mot à afficher et/ou énoncer soit dans une portion de mémoire correspondant à une langue, soit dans une autre portion de mémoire correspondant à une autre langue, selon la nature de ce mot.In a particular embodiment, such a module is provided with means for calling, on the basis of a digital code, a word to be displayed and / or speaking either in a portion of memory corresponding to a language, or in another portion of memory corresponding to another language, depending on the nature of this word.

De préférence, un tel module comporte des moyens pour appeler des éléments de messages concernant des éléments de vocabulaire courant dans une même portion de mémoire, et pour appeler des éléments de vocabulaire susceptibles d'apparaître sur des panneaux routiers dans une autre portion de mémoire correspondant à une autre langue.Preferably, such a module includes means for calling up elements of messages relating to vocabulary elements current in the same portion of memory, and for calling up vocabulary elements capable of appearing on road signs in another corresponding portion of memory to another language.

Dans un autre mode de réalisation particulier, un tel module est muni de moyens pour, sur la base d'un mot désigné par un usager et présent dans une portion de mémoire correspondant à une langue, appeler un mot correspondant dans une autre portion de mémoire correspondant à une autre langue, et de moyens pour afficher et/ou énoncer au moins ce dernier mot.In another particular embodiment, such a module is provided with means for, on the basis of a word designated by a user and present in a memory portion corresponding to a language, to call a corresponding word in another memory portion corresponding to another language, and means for displaying and / or speaking at least this last word.

Ces aspects de l'invention ainsi que d'autres aspects plus détaillés apparaîtront plus clairement grâce à la description suivante d'un mode de réalisation constituant un exemple non limitatif.These aspects of the invention as well as other more detailed aspects will become more clearly apparent from the following description of an embodiment constituting a nonlimiting example.

La figure 1 représente schématiquement un récepteur autoradio équipé de l'invention.FIG. 1 schematically represents a car radio receiver equipped with the invention.

La figure 2 représente plus en détail la partie concernée par l'invention, et ses connexions avec le reste de l'appareil.Figure 2 shows in more detail the part concerned by the invention, and its connections with the rest of the apparatus.

La description qui suit concerne un autoradio destiné à recevoir et exploiter des signaux dits RDS/TMC. Il est clair que l'homme du métier saurait adapter cette description au cas d'un appareil de navigation ou de routage, par exemple d'un genre connu sous le nom "CARIN" ou "SOCRATES", d'autant que la partie qui met en oeuvre l'invention peut être semblable dans un autoradio et dans un appareil de navigation.The following description relates to a car radio intended to receive and process so-called RDS / TMC signals. It is clear that a person skilled in the art would be able to adapt this description to the case of a navigation or routing device, for example of a type known as "CARIN" or "SOCRATES", all the more so as the part which implements the invention may be similar in a car radio and in a navigation device.

Le récepteur de la figure 1 comporte, à partir d'une antenne 1, un dispositif 2 ("tuner") contenant un circuit de syntonisation et un circuit de changement de fréquence, suivi d'un dispositif 3 contenant un amplificateur à fréquence intermédiaire et un démodulateur.The receiver of FIG. 1 comprises, from an antenna 1, a device 2 ("tuner") containing a tuning circuit and a frequency change circuit, followed by a device 3 containing a amplifier intermediate frequency and a demodulator.

Dans le procédé dit RDS ("Radio Data System"), une sous-porteuse FM est modulée par des signaux numériques de données, utiles à la réception des différents émetteurs d'une même chaîne. Pour traiter ces signaux, le récepteur comporte un décodeur 13 de messages RDS.In the so-called RDS ("Radio Data System") process, an FM subcarrier is modulated by digital data signals, useful for the reception of different transmitters of the same chain. To process these signals, the receiver includes a decoder 13 for RDS messages.

Dans le cas du procédé connu dit "TMC" (Traffic Message Channel"), des messages d'information sur la circulation sont incorporés dans certains champs numériques des signaux RDS, par exemple : "bouchon trois km avant l'entrée de Lille".In the case of the known process known as "TMC" (Traffic Message Channel "), traffic information messages are incorporated into certain digital fields of RDS signals, for example:" traffic jam three km before entering Lille ".

Pour traiter les messages TMC, le récepteur comporte un module 14, auquel les données RDS du décodeur 13 sont amenées par un bus 21, pour être analysées et éventuellement mémorisées. Pour permettre de délivrer des messages sous forme vocale, ce module 14 est relié à un système amplificateur audio 4 suivi d'un haut-parleur 5. Pour permettre d'afficher des messages sous forme écrite, il est relié à un dispositif d'interface entrée/sortie 18 relié à un écran d'affichage 10, par exemple à cristaux liquides. Pour assurer une interactivité avec l'usager, l'interface entrée/sortie 18 est reliée à un clavier de commande 12.To process the TMC messages, the receiver includes a module 14, to which the RDS data of the decoder 13 is brought by a bus 21, to be analyzed and possibly stored. To enable messages to be delivered in voice form, this module 14 is connected to an audio amplifier system 4 followed by a loudspeaker 5. To allow messages to be displayed in written form, it is connected to an interface device input / output 18 connected to a display screen 10, for example with liquid crystal. To ensure interactivity with the user, the input / output interface 18 is connected to a control keyboard 12.

Les messages TMC standard sont constitués de plusieurs champs de données numériques, reçus dans les données RDS, et qui désignent des éléments de vocabulaire par un nombre :

  • un 1er champ, de 11 bits, contient un nombre qui désigne un élément de vocabulaire (mot ou groupe de mots) décrivant un événement,
  • un 2e champ, de 16 bits, contient un nombre qui désigne un élément de vocabulaire définissant la localisation concernée par l'événement en question,
  • un 3e champ, de 3 bits, contient une donnée décrivant une extension de la localisation concernée,
  • un 4e champ, de 1 bit, décrit le sens du trajet concerné,
  • un 5e champ, de 3 bits, donne la durée de validité du message,
  • un 6e champ, de 1 bit, indique s'il est recommandé ou non de prendre une déviation.
Standard TMC messages are made up of several fields of digital data, received in RDS data, and which designate vocabulary elements by a number:
  • a 1st field, of 11 bits, contains a number which designates a vocabulary element (word or group of words) describing an event,
  • a 2nd field, 16 bits, contains a number which identifies a vocabulary element defining the location whereto the relevant event in question,
  • 3 rd field, 3 bits, contains data describing an extension of the location concerned,
  • a 4 th field, of 1 bit, describes the direction of the path concerned,
  • a 5 th field, of 3 bits, gives the duration of validity of the message,
  • a 6 th field, of 1 bit, indicates whether or not it is recommended to take a deviation.

Le contenu de chacun des champs doit être traité de façon à exprimer en clair (à voix haute ou par écrit) ce dont il s'agit. Pour cela est prévue une mémoire permanente, dans laquelle sont stockées des informations en clair, sous forme par exemple des codes ASCII des caractères d'un message à afficher, et/ou la séquence de phonèmes (pour mémoire, un phonème est une unité sonore d'un langage) qui lui correspond, à des adresses correspondant aux différents contenus possibles de chaque champ, ce qui permet de retrouver les informations à partir du contenu d'un champ.The content of each of the fields must be treated so as to express clearly (aloud or in writing) what it is about. For this is provided a permanent memory, in which information is stored in clear, in the form for example of the ASCII codes of the characters of a message to be displayed, and / or the sequence of phonemes (for the record, a phoneme is a sound unit of a language) which corresponds to it, to addresses corresponding to the different possible contents of each field, which makes it possible to find the information from the content of a field.

Par exemple, le 1er champ (décrivant un événement), qui comporte 11 bits, est associé à une mémoire qui peut contenir en clair 2048 éléments de vocabulaire (soit 211 éléments de vocabulaire), chacun étant trouvé à l'adresse définie par le contenu du champ. Ces éléments de vocabulaire sont par exemple "bouchon", "travaux", "accident", etc.For example, the 1 st field (describing an event), which has 11 bits, is associated with a memory which can contain in plain text 2048 vocabulary elements (i.e. 2 11 vocabulary elements), each being found at the address defined by the content of the field. These vocabulary elements are for example "traffic jam", "work", "accident", etc.

Le 2e champ (décrivant une localisation), qui comporte 16 bits, est associé à une mémoire, dite mémoire des points de localisation, qui peut contenir en clair jusqu'à 65536 éléments de vocabulaire (soit 216 éléments de vocabulaire) qui comprennent des données complètes sur notamment des noms de localisations, leur type, la région à laquelle ils appartiennent, les points suivant et précédent, etc, chaque élément de vocabulaire étant en principe trouvé à une adresse désignée par le contenu du champ. Ces éléments de vocabulaire sont par exemple "Paris", ou "Lille", ou "la sortie 21", etc. Pour chaque pays concerné sont définies plusieurs bases de données différentes, correspondant au 2e champ TMC (décrivant une localisation), de 65536 éléments chacune, à choisir selon l'application. Le pays concerné est indiqué dans un code dit PI porté par les données RDS, et la référence de la base de données choisie est indiqué dans un "message système" qui est émis de temps en temps par chaque émetteur RDS/TMC.The 2 nd field (describing a location), which comprises 16 bits, is associated with a memory, known as the location point memory, which can contain in the clear up to 65,536 vocabulary elements (i.e. 2 16 vocabulary elements) which include complete data on in particular localization names, their type, the region to which they belong, the next and previous points, etc., each vocabulary element being in principle found at an address designated by the content of the field. These vocabulary elements are for example "Paris", or "Lille", or "the exit 21", etc. For each country concerned are defined several different databases, corresponding to the 2nd field TMC (describing a location) of 65536 elements each for selection depending on the application. The country concerned is indicated in a so-called PI code carried by the RDS data, and the reference of the chosen database is indicated in a "system message" which is sent from time to time by each RDS / TMC transmitter.

Dans le 3e champ, différents types d'extensions sont définis. On entend par extension le fait que l'événement considéré s'étend par exemple jusqu'à la localisation suivante.In the 3rd field, different types of extensions are defined. By extension is meant the fact that the event considered extends for example to the following location.

Dans le 4e champ, un bit 0 signifie par exemple "sens Paris → Lille", alors qu'un bit 1 signifierait "sens Lille → Paris" (c'est le contenu du champ 2 qui indique qu'on est sur une liaison entre Paris et Lille, mais le sens n'y est pas indiqué).In the 4 th field, a bit 0 means for example "direction Paris → Lille", while a bit 1 would mean "direction Lille → Paris" (it is the content of field 2 which indicates that we are on a link between Paris and Lille, but the direction is not indicated there).

Sur la figure 2, le module 14 comprend un microcontrôleur 7 qui génère des signaux de contrôle et traite les signaux qui sortent des différents dispositifs, auxquels il est relié par un bus d'adresses 15 et par un bus de données 21. Le module 14 comprend aussi plusieurs mémoires :

  • une mémoire volatile 9 dite "RAM", pour le stockage de données valides à un instant donné,
  • une mémoire permanente 8 pour le stockage de descriptions de vocabulaire fixées une fois pour toutes par le standard TMC pour une langue déterminée, en correspondance avec certains champs, par exemple le 1er champ,
  • et une mémoire 22, 23 constituée d'un lecteur 22 de carte à mémoire et d'une carte à mémoire amovible 23, par exemple de type PCMCIA, dans laquelle sont stockés plus spécialement les données correspondant au 2e champ des données TMC et entre autres, pour chacun des noms de localisations prévus pour un pays donné, son épellation par exemple en caractères ASCII, et la séquence de phonèmes qui lui correspond. La mémoire 23 contient ces données dans plusieurs langues, correspondant à une nationalité d'usager et/ou à une ou plusieurs régions données.
In FIG. 2, the module 14 comprises a microcontroller 7 which generates control signals and processes the signals which come out of the various devices, to which it is connected by an address bus 15 and by a data bus 21. The module 14 also includes several memories:
  • a volatile memory 9 called "RAM", for the storage of data valid at a given instant,
  • a permanent memory 8 for the storage of vocabulary descriptions fixed once and for all by the TMC standard for a determined language, in correspondence with certain fields, for example the 1st field,
  • and a memory 22, 23 consists of a 22 memory card reader and a removable memory card 23, for example of the PCMCIA type, wherein are stored in particular the data corresponding to 2nd and TMC data field between others, for each of the localization names provided for a given country, its spelling for example in ASCII characters, and the sequence of phonemes which corresponds to it. The memory 23 contains this data in several languages, corresponding to a nationality of user and / or to one or more given regions.

Le microcontrôleur 7 sélectionne et prépare des données numériques, par exemple une séquence de caractères ASCII désignant des parties de message, permettant à l'écran d'affichage 10 d'afficher ces éléments, ou des symboles désignant chacun un phonème, permettant à un module de synthèse vocale 20 connu en soi, d'engendrer les phonèmes sous la forme de signaux analogiques délivrés à l'amplificateur audio 4 suivi du haut-parleur 5.The microcontroller 7 selects and prepares digital data, for example a sequence of ASCII characters designating parts of a message, allowing the display screen 10 to display these elements, or symbols each designating a phoneme, allowing a module of speech synthesis 20 known per se, to generate the phonemes in the form of analog signals delivered to the audio amplifier 4 followed by the speaker 5.

Lorsqu'un message TMC arrive, le microcontrôleur 7 reçoit de la part du décodeur RDS 13 les contenus des champs, et les inscrit dans la mémoire 9. Pour l'affichage sur l'écran 10 et/ou l'émission vocale de ce message, le microcontrôleur 7 extrait de la mémoire 9 au moins les contenus des champs 1, 3, 4 qu'il interprète de façon connue, entre autres en lisant dans la mémoire 8 les constituants du message à produire pour annoncer l'événement correspondant dans la langue de l'usager, sous la forme de symboles décrivant la phonétique des énoncés correspondants.When a TMC message arrives, the microcontroller 7 receives the contents of the fields from the RDS decoder 13, and writes them to memory 9. For display on the screen 10 and / or the voice transmission of this message, the microcontroller 7 extracts from the memory 9 at least the contents of the fields 1, 3, 4 which it interprets in a known manner, inter alia by reading in the memory 8 the constituents of the message to be produced to announce the corresponding event in the language of the user, in the form of symbols describing the phonetics of the corresponding statements.

Puis, dans un premier mode de fonctionnement, le microcontrôleur extrait de la mémoire 9 le 2e champ, il en déduit une adresse dans la mémoire 23 au moyen de laquelle il lit dans cette mémoire l'épellation du nom de localisation correspondant dans la langue du pays traversé, et les phonèmes le constituant, et il insère le nom écrit à l'endroit convenable dans le message à afficher pour annoncer l'événement, et il place les phonèmes du nom, à l'endroit convenable dans la séquence des symboles de phonèmes qu'il fournit au générateur 20. Ainsi il est muni de moyens pour appeler un mot dans une des portions de mémoire ou dans l'autre selon la nature de ce mot, c'est-à-dire ici dans une portion de mémoire correspondant à la langue de l'usager pour les champs TMC 1, 3, 4, et dans une portion de mémoire correspondant à la langue du pays traversé, pour le 2e champ TMC.Then, in a first operating mode, the microcontroller extracts from memory 9 the 2 nd field, it deduces therefrom an address in memory 23 by means of which it reads from this memory the spelling of the corresponding location name in the language of the country crossed, and the phonemes constituting it, and it inserts the name written in the appropriate place in the message to be displayed to announce the event, and it places the phonemes of the name, in the appropriate place in the sequence of symbols of phonemes which it supplies to the generator 20. Thus it is provided with means for calling up a word in one of the portions of memory or in the other depending on the nature of this word, that is to say here in a portion of memory corresponding to the language of the user for TMC fields 1, 3, 4, and a memory portion corresponding to the language of the country crossed for the 2nd field TMC.

Dans une variante de fonctionnement, lorsque le microcontrôleur extrait de la mémoire 9 le 2e champ, il lit dans la mémoire 23 d'une part l'épellation du nom de localisation correspondant dans la langue de l'usager, et les phonèmes le constituant, et d'autre part l'épellation du nom de localisation correspondant dans la langue du pays traversé, et les phonèmes le constituant. Il insère ensuite successivement les noms dans les deux langues aux endroits convenables (avec éventuellement le second nom entre parenthèses) dans le message à afficher pour annoncer l'événement, et il place les phonèmes des noms, successivement dans les deux langues (avec éventuellement une liaison du genre "ou bien", ou "qui se dit", etc, entre eux), aux endroits convenables dans la séquence des symboles de phonèmes qu'il fournit au générateur 20.In a variant of operation, when the microcontroller extracts from memory 9 the 2 nd field, it reads from memory 23 on the one hand the spelling of the corresponding location name in the language of the user, and the phonemes constituting it , and on the other hand the spelling of the corresponding localization name in the language of the country crossed, and the phonemes constituting it. It then successively inserts the names in the two languages in the appropriate places (with the second name possibly in parentheses) in the message to be displayed to announce the event, and it places the phonemes of the names, successively in the two languages (with possibly a link like "or", or "who says", etc., between them), at the appropriate places in the sequence of symbols of phonemes which it supplies to the generator 20.

Il peut également être prévu une touche particulière sur le clavier 12 pour demander une fonction "traduction". Cette demande peut aussi être formulée au moyen d'une combinaison de touches standard du clavier 12. Dès que la demande a été formulée, le microcontrôleur scrute le clavier pour lire le nom qui y est tapé par l'usager, ou bien il affiche sur l'écran 10 une liste de noms parmi lesquels l'usager peut en sélectionner un. Ensuite il recherche ce nom dans la mémoire, et lorsqu'il l'a trouvé, il lit le nom correspondant dans l'autre langue et l'affiche sur l'écran.A special key can also be provided on the keyboard 12 to request a "translation" function. This request can also be made using a standard keyboard combination of keys 12. As soon as the request has been made, the microcontroller scans the keyboard to read the name entered by the user, or it displays on screen 10 a list of names from which the user can select one. Then it searches for that name in memory, and when it finds it, it reads the corresponding name in the other language and displays it on the screen.

Le récepteur est bien entendu muni de moyens pour sélectionner automatiquement, sur la base du code PI, les portions de mémoire voulues, selon la langue du signal radio reçu, c'est-à-dire celle du pays traversé.The receiver is of course provided with means for automatically selecting, on the basis of the PI code, the desired portions of memory, according to the language of the radio signal received, that is to say that of the country crossed.

Les fonctions de traduction ainsi que celles de double énoncé et/ou de double affichage peuvent aussi s'appliquer éventuellement à des éléments de vocabulaire des autres champs TMC, afin de permettre une meilleure compréhension des certains panneaux. En effet les panneaux de localité ne sont pas les seuls à être lus par un automobiliste ; si un panneau allemand annonce "Umleitung beratet", il peut être utile à un automobiliste français de savoir que cela signifie "déviation conseillée" !The translation functions as well as those of double utterance and / or of double display can also possibly be applied to vocabulary elements from other TMC fields, in order to allow a better understanding of certain panels. Indeed, the locality signs are not the only ones to be read by a motorist; if a German sign announces "Umleitung beratet", it may be useful for a French motorist to know that it means "deviation advised"!

On peut même imaginer, lorsque l'appareil comporte un afficheur graphique (par exemple dans CARIN pour l'affichage de cartes), qu'il fournisse une "traduction" de panneaux routiers particuliers à un pays et qui n'existent pas dans un autre, sous forme de dessins montrant chacun des panneaux en correspondance avec son équivalent d'un autre pays, ou d'un texte explicatif dans la langue de l'usager, associé au panneau étranger.One can even imagine, when the device includes a graphic display (for example in CARIN for the display of maps), that it provides a "translation" of road signs specific to one country and which do not exist in another , in the form of drawings showing each of the panels in correspondence with its equivalent from another country, or of an explanatory text in the language of the user, associated with the foreign panel.
