La présente invention concerne un récepteur de radio pour véhicule automobile, comportant une partie amovible dans laquelle sont logés des éléments réalisant une fonction indispensable du récepteur et munie de touches et d'un écran d'affichage.The present invention relates to a radio receiver for a motor vehicle, comprising a removable part in which are housed elements performing an indispensable function of the receiver and provided with keys and a display screen.
Un tel récepteur radio est protégé contre le vol, du fait que la partie amovible a des fonctions essentielles, et que par conséquent l'usage du récepteur est impossible lorsqu'elle est retirée.Such a radio receiver is protected against theft, because the removable part has essential functions, and therefore the use of the receiver is impossible when it is removed.
Un récepteur de radio pour véhicule muni d'une telle partie amovible anti vol est connu du document EP-A-0 253 947. Selon ce document, l'autoradio possède une partie amovible et les fonctions de la partie restante du récepteur sont interrompues lorsqu'on enlève la partie amovible.A vehicle radio receiver equipped with such a removable anti-theft part is known from document EP-A-0 253 947. According to this document, the car radio has a removable part and the functions of the remaining part of the receiver are interrupted when 'the removable part is removed.
L'invention se propose d'augmenter les possibilités d'une telle partie amovible.The invention proposes to increase the possibilities of such a removable part.
A cet effet l'appareil selon l'invention est remarquable en ce que la partie amovible est munie d'un circuit de mesure de temps programmable, de moyens pour programmer le circuit de mesure de temps à l'aide des dites touches, et d'un élément sonore déclenché par le circuit de mesure de temps lorsque le temps programmé est écoulé.To this end, the apparatus according to the invention is remarkable in that the removable part is provided with a programmable time measurement circuit, with means for programming the time measurement circuit using said keys, and d '' a sound element triggered by the time measurement circuit when the programmed time has elapsed.
Ainsi l'utilisateur possède un moyen pour être prévenu par exemple que son temps de parking est écoulé, sans avoir à acheter un minuteur et à s'encombrer d'un élément supplémentaire.Thus the user has a means to be notified for example that his parking time has expired, without having to buy a timer and to burden himself with an additional element.
L'invention est donc basée sur l'idée que l'on peut tirer parti d'éléments déjà présents dans la partie amovible pour fournir des services supplémentaires inattendus.The invention is therefore based on the idea that one can take advantage of elements already present in the removable part to provide unexpected additional services.
Dans un mode de réalisation électronique avantageux, la partie amovible est munie de moyens pour afficher à la demande le temps programmé, sur l'écran d'affichage.In an advantageous electronic embodiment, the removable part is provided with means for displaying the programmed time on demand on the display screen.
Un tel minuteur, dans une réalisation séparée, comporterait son propre écran d'affichage et ses propres touches, alors que ces éléments sont déjà présents dans la partie amovible de l'appareil.Such a timer, in a separate embodiment, would have its own display screen and its own keys, while these elements are already present in the removable part of the device.
La partie amovible est avantageusement munie d'une mémoire, de moyens pour y introduire des données à l'aide des dites touches, et de moyens pour afficher ces données sur l'écran d'affichage.The removable part is advantageously provided with a memory, means for entering data therein using said keys, and means for displaying this data on the display screen.
Ainsi elle peut aussi servir de mémento.So it can also serve as a reminder.
Avantageusement, la dite partie amovible étant munie d'un circuit générateur capable de générer plusieurs suites d'impulsions et de moyens pour envoyer à la demande l'une de ces suites au moyen de lumière infra-rouge, ce circuit générateur est muni de moyens pour générer des suites d'impulsions destinées au réglage de certaines fonctions du véhicule.Advantageously, said removable part being provided with a generator circuit capable of generating several sequences of pulses and of means for sending one of these suites on demand by means of infrared light, this generator circuit is provided with means to generate sequences of pulses intended for the adjustment of certain vehicle functions.
Ainsi il est possible d'utiliser la dite partie amovible pour commander, éventuellement à distance, certaines fonctions du véhicule, telles que la mise à l'heure de la montre, le réglage de la climatisation, etc.Thus it is possible to use said removable part to control, possibly remotely, certain functions of the vehicle, such as setting the time of the watch, adjusting the air conditioning, etc.
Pour un véhicule automobile équipé d'un système de verrouillage ou déverrouillage des serrures de portières par télécommande au moyen de lumière infra-rouge, il est intéressant en outre que la dite partie amovible soit munie d'un circuit générateur capable d'engendrer une suite d'impulsions codées propre à commander les serrures du véhicule, et de moyens pour envoyer la dite suite d'impulsions au moyen de lumière infra-rouge émise par une diode électroluminescente, lorsqu'on appuie sur une des touches.For a motor vehicle equipped with a system for locking or unlocking door locks by remote control by means of infrared light, it is also advantageous for said removable part to be provided with a generator circuit capable of generating a series coded pulses suitable for controlling the vehicle locks, and means for sending said sequence of pulses by means of infrared light emitted by a light-emitting diode, when one of the keys is pressed.
Ainsi l'utilisateur n'a pas besoin de transporter une clé d'ouverture des portes en plus de la dite partie amovible.Thus the user does not need to transport a door opening key in addition to said removable part.
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 non limitatif.These aspects of the invention as well as other more detailed aspects will become more clearly apparent from the following description of a nonlimiting embodiment.
La figure unique représente en perspective un appareil selon l'invention avec une partie amovible.The single figure shows in perspective an apparatus according to the invention with a removable part.
Le récepteur de radio pour véhicule automobile qui est représenté possède un corps principal 1 pouvant recevoir une façade amovible 2 qui vient se loger dans un réceptacle 3, au fond duquel des contacts électriques 6 permettent des interconnexions entre la partie amovible 2 et le corps 1 du récepteur lorsque la partie amovible est en place dans le réceptacle 3.The radio receiver for a motor vehicle which is shown has a main body 1 which can receive a
La partie amovible comporte, à l'intérieur, des éléments réalisant une fonction indispensable du récepteur, par exemple un syntoniseur. Elle est munie de touches 5 pour permettre la commande de la fonction en question et d'un écran d'affichage 4 pour afficher les résultats obtenus par la dite commande. Les touches peuvent être par exemple des touches marquées "+" et "-" qui engendrent respectivement l'augmentation de la fréquence de l'onde reçue ou sa diminution, l'écran indiquant la valeur de cette fréquence au fur et à mesure qu'elle change. Il peut aussi y avoir des touches numérotées pour la sélection de canaux ou l'introduction d'une fréquence par sa valeur numérique, et ainsi de suite. Dans le cas où la partie amovible présente les fonctions d'une montre l'écran sert à afficher l'heure, et les touches à mettre la montre à l'heure.The removable part includes, inside, elements performing an indispensable function of the receiver, for example a tuner. It is provided with
La partie amovible est munie d'un circuit de mesure de temps programmable. Dans le cas où la partie amovible présente les fonctions d'une montre, c'est en fin de compte presque toute la montre qui serait amovible, avec son circuit de mesure de temps. Des touches spéciales sont prévues pour la programmation de ce circuit de mesure de temps. Les touches prévues pour le syntoniseur du récepteur radio ou pour la mise à l'heure de la montre peuvent aussi servir pour programmer le circuit de mesure de temps, par exemple s'il est prévu d'appuyer en même temps sur une autre touche pour donner une seconde signification à certaines touches. Un élément sonore est prévu, déclenché par le circuit de mesure de temps programmable, lorsque le temps programmé est écoulé.The removable part is provided with a programmable time measurement circuit. In the case where the removable part has the functions of a watch, it is ultimately almost the entire watch which would be removable, with its time measurement circuit. Special keys are provided for programming this time measurement circuit. The keys provided for the tuner of the radio receiver or for setting the time of the watch can also be used to program the time measurement circuit, for example if it is planned to press at the same time another key to give a second meaning to certain keys. An audible element is provided, triggered by the programmable time measurement circuit, when the programmed time has elapsed.
L'homme du métier est capable de réaliser un circuit de mesure de temps programmable facilement : un microprocesseur est prévu dans les récepteurs de radio modernes pour gérer la commande et les fonctions du syntoniseur ainsi que pour gérer l'affichage et ce microprocesseur peut être programmé de façon connue pour constituer un compteur de temps, et pour "lire" l'actionnement de certaines touches et réaliser des branchements logiciels en conséquence.Those skilled in the art are capable of implementing an easily programmable time measurement circuit: a microprocessor is provided in modern radio receivers to manage the control and the functions of the tuner as well as to manage the display and this microprocessor can be programmed. in a known manner to constitute a time counter, and to "read" the actuation of certain keys and make software connections accordingly.
Le temps programmé est affiché sur l'écran d'affichage. Ceci peut se produire en permanence lorsque l'on a sélectionné la fonction de mesure de temps, indiquant alors au fur et à mesure la décroissance du temps restant. Il peut aussi être prévu que ce temps s'affiche seulement lorsqu'on presse certaines touches.The programmed time is displayed on the display screen. This can happen continuously when you have selected the time measurement, then progressively indicating the decrease in the remaining time. It can also be expected that this time is displayed only when certain keys are pressed.
La partie amovible est munie d'une mémoire dans laquelle il est possible d'introduire des données. Le microprocesseur gère sur commande l'entrée des données dans la mémoire au moyen des dites touches actionnées par l'utilisateur, puis lors de l'appui sur certaines touches, leur rappel à partir de la mémoire et leur affichage sur l'écran d'affichage.The removable part is provided with a memory into which it is possible to enter data. The microprocessor manages on command the entry of data in the memory by means of the said keys actuated by the user, then when pressing certain keys, their recall from the memory and their display on the screen of display.
La partie amovible est munie en outre d'un circuit générateur de suites d'impulsions codées en lumière infra-rouge, générant à la demande plusieurs suites d'impulsions différentes. Ces suites d'impulsions peuvent être obtenues au moyen du même microprocesseur, associé à un amplificateur pour amplifier les impulsions et les appliquer à une diode électro-luminescente 9, de façon à envoyer la dite suite d'impulsions au moyen de lumière infra-rouge. Là encore des touches spéciales peuvent être prévues pour déclencher l'envoi de cette suite d'impulsions, mais des touches prévues pour le syntoniseur peuvent aussi remplir cet office.The removable part is further provided with a generator circuit of pulse sequences coded in infrared light, generating on demand several different pulse sequences. These pulse sequences can be obtained by means of the same microprocessor, associated with an amplifier to amplify the pulses and apply them to a light-emitting
Le corps du récepteur est muni d'un élément 8 récepteur de lumière infrarouge, et de circuits de décodage non représentés connus en soi, pour interpréter les différentes suites d'impulsions reçues par l'élément récepteur 8 et réagir en conséquence, comme cela est en usage par exemple dans les téléviseurs, pour le réglage de paramètres tels que le volume son, la balance stéréo, etc. Lorsque la partie amovible est en place dans le réceptacle 3, les mêmes suites d'impulsions sont transmises galvaniquement par les contacts 6, et provoquent les mêmes effets.The receiver body is provided with an infrared light receiving element 8, and decoding circuits, not shown, known per se, to interpret the different sequences of pulses received by the receiving element 8 and to react accordingly, as is used for example in televisions, for adjusting parameters such as sound volume, stereo balance, etc. When the removable part is in place in the
Le véhicule automobile étant équipé d'un système de verrouillage ou déverrouillage des serrures de portières par télécommande au moyen de lumière infra-rouge, le circuit générateur d'impulsions est conçu pour engendrer, toujours grâce à une programmation ad hoc du microprocesseur et au moyen du même amplificateur et de la même diode électroluminescente, des impulsions propres à commander les serrures du véhicule. La partie amovible peut être alors utilisée indifféremment à la place de la clé de télécommande habituelle, pour verrouiller et déverrouiller les portières du véhicule.The motor vehicle being equipped with a system for locking or unlocking the door locks by remote control by means of infrared light, the pulse generator circuit is designed to generate, always by ad hoc programming of the microprocessor and by means from the same amplifier and the same light-emitting diode, pulses capable of controlling the vehicle locks. The removable part can then be used interchangeably in place of the usual remote control key, to lock and unlock the vehicle doors.
En plus de l'effet anti-vol constitué par le retrait de la partie amovible, il est possible de munir le corps du récepteur d'un système de verrouillage de ses fonctions, qui est déverrouillable au moyen d'un code secret, fourni sous la forme d'une suite d'impulsions. Le véhicule automobile étant équipé par ailleurs d'un bus (non représenté) pour transmettre les ordres d'un système centralisé de verrouillage ou déverrouillage des serrures de portières, le corps du récepteur est muni d'un connecteur 7 pour la connexion au dit bus. Ce connecteur est représenté sur le côté du corps pour être visible, mais il est évident qu'il sera plutôt placé en pratique à l'arrière.In addition to the anti-theft effect constituted by the removal of the removable part, it is possible to provide the receiver body with a system of locking of its functions, which is unlockable by means of a secret code, supplied in the form of a series of pulses. Since the motor vehicle is also equipped with a bus (not shown) for transmitting orders from a centralized system for locking or unlocking door locks, the receiver body is provided with a connector 7 for connection to said bus. . This connector is shown on the side of the body to be visible, but it is obvious that it will rather be placed in practice at the rear.
La suite d'impulsions constituant le code secret d'ouverture des portières est transmise par le susdit bus, et donc amenée au connecteur 7, par un système centralisé de verrouillage ou déverrouillage des serrures de portières, lorsque l'automobiliste déverrouille les portières au moyen de sa clé de télécommande ou de la partie amovible. Le corps du récepteur est équipé de moyens de reconnaissance de la suite d'impulsions électriques qui est amenée par le bus sur le connecteur 7. Ainsi le récepteur de radio est verrouillé et déverrouillé en même temps que les portières et par le même code.The series of pulses constituting the secret door opening code is transmitted by the aforementioned bus, and therefore brought to the connector 7, by a centralized system for locking or unlocking the door locks, when the motorist unlocks the doors by means its remote control key or the removable part. The receiver body is equipped with means for recognizing the series of electrical pulses which is brought by the bus to the connector 7. Thus the radio receiver is locked and unlocked at the same time as the doors and by the same code.
L'alimentation de la partie amovible, lorsqu'elle est détachée du récepteur, est réalisée au moyen d'une ou plusieurs piles d'encombrement réduit.The supply of the removable part, when it is detached from the receiver, is carried out by means of one or more compact batteries.
Bien qu'elle soit représentée ici à plat sur la face avant du récepteur, il est clair que la partie détachable peut aussi par exemple être introduite dans une fente de la façade, à la manière d'une carte de crédit dans un lecteur de carte.Although it is shown here flat on the front of the receiver, it is clear that the detachable part can also, for example, be inserted into a slot in the front, like a credit card in a card reader .
Dans le cas où un véhicule n'est pas équipé d'une télécommande par lumière infra-rouge, plusieurs caractéristiques de l'invention s'appliquent néanmoins : la partie amovible, qui comporte bien entendu un minuteur, peut comporter aussi une commande infra-rouge de fonctions d'un poste de radio, et un mémento aide mémoire. En outre le système de verrouillage des fonctions d'un récepteur, qui est déverrouillable au moyen d'un code secret, fourni sous la forme d'une suite d'impulsions, peut être actionné par un bus même lorsque le système centralisé de verrouillage ou déverrouillage des serrures est actionné au moyen d'une clé mécanique ordinaire.In the case where a vehicle is not equipped with a remote control by infrared light, several characteristics of the invention nevertheless apply: the removable part, which of course includes a timer, can also include an infrared control radio functions red, and a memory aid. Furthermore, the receiver function locking system, which can be unlocked by means of a secret code, supplied in the form of a pulse sequence, can be actuated by a bus even when the central locking system or unlocking the locks is operated by an ordinary mechanical key.
