Ces systèmes comprennent également une pluralité de témoins qui ont le rôle de signaler le fonctionnement de certains dispositifs, tels que les feux d1,éclairage, le starter, le frein à main, etc. et le non fonctionnement ou le mauvais fonctionnement de certains autres, tels que portières ouvertes, feux en panne, tension insuffisante de la batterie, usure des plaquettes des freins,' etc. These systems also include a plurality of tell-tales which have the role of signaling the operation of certain devices, such as lights, lighting, choke, handbrake, etc. and the non-functioning or malfunction of certain others, such as open doors, faulty lights, insufficient battery voltage, wear of the brake pads, etc.
En alternative à ces systèmes traditionnels, on étudie actuellement des systèmes informatiques d'avant-garde dans lesquels les données concernant l'état de fonctionnement des voitures sont exploitées par un microcalculateur et peuvent être visualisées sur un écran vidéo en meme temps que les instructions des programmes d'exploitation. As an alternative to these traditional systems, avant-garde computer systems are currently being studied in which the data relating to the operating state of the cars are exploited by a microcomputer and can be viewed on a video screen at the same time as the instructions of the operating programs.
Le but de la présente invention est de créer un système informatique de bord, réalisé avec un microcalculateur et un écran vidéo, capable non seulement de saisir et de visualiser les informations concernant l'état de fonctionnement de la voiture, mais également des informations de caractère touristique concernant les localités dans lesquelles la voiture est amenée à circuler. The object of the present invention is to create an on-board computer system, produced with a microcomputer and a video screen, capable not only of entering and viewing information concerning the operating state of the car, but also character information. tourist concerning the localities in which the car is brought to circulate.
Le système informatique selon l'invention comprend par conséquent au moins un microcalculateur programmable relié d'une part à une unité d'entrée des commandes concernant des demandes d'informations et à une unité de sortie pour la visualisation des informations, et relié d'autre part à des capteurs de certains paramètres préfixés de la voiture et à une interface de lecture d'une unité de mémoire auxiliaire, ledit système étant caractérisé par le fait que dans ladite unité de mémoire auxiliaire sont stockées les informations touristiques concernant des localités données et les instructions des programmes pour repérer les informations touristiques désirées. The computer system according to the invention therefore comprises at least one programmable microcomputer connected on the one hand to an input unit for commands concerning requests for information and to an output unit for viewing information, and connected to on the other hand, to sensors for certain prefixed parameters of the car and to an interface for reading an auxiliary memory unit, said system being characterized in that in said auxiliary memory unit are stored tourist information relating to given localities and program instructions for locating desired tourist information.
Selon une solution préférée, dans ladite unité de mémoire auxiliaire sont stockées les données qui définissent les plans de certaines villes, régions ou pays donnés, qui peuvent être visualisés, par exemple sur un écran vidéo, ainsi que des informations concernant des hôtels, restaurants, magasins, monuments, rues, places, parcs, lieux caractéristiques de villes ou de régions, et des renseignements d'utilité publique et d'intérêt général. According to a preferred solution, in said auxiliary memory unit are stored the data which define the maps of certain cities, regions or countries, which can be viewed, for example on a video screen, as well as information concerning hotels, restaurants, stores, monuments, streets, squares, parks, characteristic places of cities or regions, and information of public utility and general interest.
La description qui va suivre, en regard du dessin annexé à titre d'exemple non limitatif, permettra de bien comprendre comment l'invention peut être miSe en pratique. The description which follows, with reference to the attached drawing by way of nonlimiting example, will make it possible to understand clearly how the invention can be put into practice.
La figure unique représente un schéma du système informatique d'une voiture, réalisé selon l'invention. The single figure represents a diagram of the computer system of a car, produced according to the invention.
Sur cette figure, la référence 10 désigne dans son ensemble un bloc, représenté en traits discontinus, qui schématise le tableau de bord (ou la console centrale) dlune voiture équipée d'un moteur à combustion interne, tous les deux non représentés. In this figure, the reference 10 designates as a whole a block, represented in broken lines, which diagrams the dashboard (or the central console) of a car equipped with an internal combustion engine, both not shown.
Le tableau de bord est doté d'un écran vidéo 11, qui est relié, à travers la ligne 12 à un microcalculateur programmable, désigné dans son ensemble par la référence 13. The dashboard has a video screen 11, which is connected, through line 12, to a programmable microcomputer, designated as a whole by the reference 13.
Parmi les composants du microcalculateur, on peut voir sur la figure l'interface de contrôle, désignée par 14, la mémoire vive, RAM 15, la mémoire morte, ROM 16, tandis que les autres composants ont été omis, ledit microcalculateur étant du type commercial, par exemple un microcalculateur nO 8051 de la Sté Intel,
Le microcalculateur 13 est relié à travers une ligne 17 à une unité à touches 18, à partir de laquelle les occupants de la voiture peuvent envoyer les demandes d'informations au microcalculateur 13.Among the components of the microcomputer, one can see on the figure the control interface, designated by 14, the random access memory, RAM 15, the read only memory, ROM 16, while the other components have been omitted, said microcomputer being of the type commercial, for example a microcomputer nO 8051 from Intel,
The microcomputer 13 is connected through a line 17 to a key unit 18, from which the occupants of the car can send requests for information to the microcomputer 13.
Les références 19, 20, 21 désignent quelques-unes des lignes qui convoient vers le microcalculateur les signaux représentatifs de l'état de fonctionnement de la voiture, comme par exemple la vitesse de rotation du moteur, la vitesse de la voiture, la tèmpérature du liquide de refroidissement du moteur, etc. The references 19, 20, 21 designate some of the lines which convey to the microcomputer the signals representative of the operating state of the car, such as for example the speed of rotation of the engine, the speed of the car, the temperature of the engine coolant, etc.
Le microcalculateur 13 est également relié, à travers une ligne 22, à une interface de lecture 23, qui à son tour est reliée à une unité de mémoire auxiliaire 25, par exemple une mémoire à bande magnétique et, à travers une ligne 24, à la mémoire vive RAM 5. The microcomputer 13 is also connected, through a line 22, to a read interface 23, which in turn is connected to an auxiliary memory unit 25, for example a magnetic tape memory and, through a line 24, to RAM 5.
Dans l'unité de mémoire auxiliaire 25 on peut charger tour à tour la cartouche d'une bande magnétique contenant les informations touristiques concernant la localité qui intéresse les voyageurs, telles que les données qui définissent les plans ou cartes de certaines villes, régions ou pays, les informations concernant des hôtels, restaurants, magasins, monuments, rues, places, parcs, lieux caractéristiques de la ville ou de la région, ainsi que des renseignements d'utilité publique et d'intérêt général. In the auxiliary memory unit 25, the cartridge can be loaded in turn with a magnetic tape containing tourist information concerning the locality which interests travelers, such as the data which define the plans or maps of certain cities, regions or countries. , information concerning hotels, restaurants, shops, monuments, streets, squares, parks, characteristic places of the city or region, as well as information of public utility and general interest.
Chaque fois que lui parviennent les demandes d'informations touristiques à travers les commandes provenant de l'unité à touches 18, le microcalculateur 13 appelle depuis la mémoire auxiliaire 25 les données correspondantes, à travers l'interface de lecture 23, et les charge dans sa mémoire vive RAM 15. Whenever tourist information requests come through the commands from the key unit 18, the microcomputer 13 calls the corresponding data from the auxiliary memory 25, through the read interface 23, and loads them into its RAM 15.
Ces données, après avoir été éventuellement traitées suivant les instructions des programmes contenus dans la mémoire morte ROM 16, sont envoyées par le microcalculateur 13, à travers l'interface de contrôle 14, vers l'écran vidéo pour être visualisées. These data, after having been possibly processed according to the instructions of the programs contained in the ROM 16, are sent by the microcomputer 13, through the control interface 14, to the video screen to be viewed.
Si par contre le microcalculateur 13 reçoit, à travers les commandes provenant de l'unité à touche 18, des demandes d'informations concernant l'état de fonctionnement de la voiture, ledit microcalculateur effectue le traitement des données concernant un seul ou quelques-uns des signaux provenant des lignes 19, 20, 21, toujours suivant les instructions des programmes stockés dans sa mémoire morte ROM 16, pour ensuite les visualiser sur l'écran vidéo 11. If, on the other hand, the microcomputer 13 receives, through the commands originating from the key unit 18, requests for information concerning the operating state of the car, said microcomputer performs the processing of the data relating to only one or a few signals from lines 19, 20, 21, always following the instructions of the programs stored in its ROM ROM 16, to then display them on the video screen 11.
