La présente invention concerne un procédé pour déceler la présence d'un récepteur dans une zone prédéterminée, une application de ce procédé à la gestion d'un système mains libres de décondamnation de véhicule automobile et un système mains libres de The present invention relates to a method for detecting the presence of a receiver in a predetermined area, an application of this method to the management of a hands-free system for unlocking a motor vehicle and a hands-free system for
décondamnation mettant en _uvre ce procédé. unlocking using this process.
Le système mains libres d'un véhicule automobile utilise traditionnellement des dispositifs portables, appelés badges identifiants, qui sont portés par les utilisateurs autorisés du véhicule et qui communiquent avec un dispositif d'identification présent dans le véhicule. Ces moyens coopèrent pour exécuter une succession d'opérations visant à autoriser ou interdire l'accès au véhicule, à la suite de l'actionnement manuel d'une The hands-free system of a motor vehicle traditionally uses portable devices, called identification badges, which are worn by authorized users of the vehicle and which communicate with an identification device present in the vehicle. These means cooperate to execute a succession of operations aimed at authorizing or prohibiting access to the vehicle, following the manual actuation of a
poignée de portière ou d'une télécommande. door handle or remote control.
Cette succession d'opérations est la suivante: - le dispositif d'identification envoie un signal de reconnaissance dans l'environnement proche du véhicule; - si un badge identifiant se trouve dans la zone couverte par le signal, ce badge identifiant répond au dispositif d'identification en renvoyant un signal d'identification; - le dispositif d'identification reçoit le signal provenant du badge et, en This sequence of operations is as follows: - the identification device sends a recognition signal to the environment near the vehicle; - if an identifying badge is in the area covered by the signal, this identifying badge responds to the identification device by returning an identification signal; - the identification device receives the signal from the badge and, in
conséquence, déclenche ou non le déverrouillage des portières. Consequently, whether or not the doors are unlocked.
Dans une version plus élaborée de ce système, qui est désigné système mains libres à sélectivité", on distingue suivant que le porteur du badge identifiant se trouve d'un côté ou de l'autre du véhicule et l'on décondamne, non pas giobalement tous les ouvrants à chaque identification positive d'un badge identifiant, mais seulement les portières In a more elaborate version of this system, which is designated "hands-free selectivity system", a distinction is made depending on whether the bearer of the identifying badge is on one side or the other of the vehicle and it is unlocked, not globally. all openings on each positive identification of an identifying badge, but only the doors
situées du même côté que le badge identifiant. located on the same side as the identifying badge.
Ainsi, en cas d'actionnement manuel d'une poignée, on essaie de déterminer si le porteur du badge identifiant se trouve du même côté du véhicule que la portière que l'on Thus, in the event of manual actuation of a handle, an attempt is made to determine whether the holder of the identifying badge is on the same side of the vehicle as the door which is
tente d'ouvrir, et l'on décondamne la portière uniquement si cette vérification est positive. tries to open, and the door is unlocked only if this check is positive.
Mais dans cette version élaborée du système mains libres, une difficulté consiste à But in this elaborate version of the hands-free system, a difficulty consists in
localiser le badge identifiant autour du véhicule. locate the identifying badge around the vehicle.
Ceci est illustré par la figure 1, qui est une vue schématique de dessus d'un véhicule automobile 1, superposée à un graphe représentant l'intensité 2 d'un signal de reconnaissance émis par un dispositif d'identifi cation d' un seul côté d u véhi cule le long This is illustrated by FIG. 1, which is a schematic top view of a motor vehicle 1, superimposed on a graph representing the intensity 2 of a recognition signal emitted by an identification device on one side vehicle running along
d'un axe transversal passant par les deux porti ères avant 3 dud it véhicule. a transverse axis passing through the two front doors 3 dud it vehicle.
Ce signal de reconnaissance est émis du côté du véhicule o une poignée de portière a été actionnée à la main. Il couvre une zone située majoritairement du côté gauche du véhicule, en étant maximal au voisinage immédiat des portières concernées -2 (ici les portières gauches) et son intensité décro^'t à mesure que l'on s'éloigne de cette This recognition signal is emitted from the side of the vehicle where a door handle has been actuated by hand. It covers an area located mainly on the left side of the vehicle, being maximum in the immediate vicinity of the doors concerned -2 (here the left doors) and its intensity decreases as one moves away from this
région de forte intensité.high intensity region.
En s'éloignant du véhicule vers la gauche, le signal décro^t jusqu'à atteindre un seuil de réception 4 en dessous duquel le baUge identifiant n'est plus capable de répondre au dispositif d'identification. Le signal décrot également en direction de l'autre côté du Moving away from the vehicle to the left, the signal decreases until it reaches a reception threshold 4 below which the identifying bar is no longer capable of responding to the identification device. The signal also decreases towards the other side of the
véhicule (le côté droit) jusqu'à atteindre le méme seuil de réception. vehicle (right side) until reaching the same reception threshold.
On voit immédiatement, d'après le schéma de la figure 1, que si le badge identifiant se trouve à proximité immédiate d'une portière droite du véhicule, il peut se trouver encore dans le champ d'émission du dispositif d'identification et peut répondre It can be seen immediately, from the diagram in FIG. 1, that if the identifying badge is in the immediate vicinity of a right door of the vehicle, it may still be in the emission field of the identification device and can reply
positivement, ce qui va déclencher, à tort, la décondamnation de la portière. positively, which will wrongly trigger the unlocking of the door.
Ce cas de figure n'est pas souhaitable car on cherche à n'ouvrir les portières dont les poignées ont été sollicitées que si le badge identifiant a été localisé du méme côté du véhicule. En d'autres termes, on souhaite déceler la présence du badge identifiant This scenario is not desirable since it is sought to open the doors whose handles have been pressed only if the identifying badge has been located on the same side of the vehicle. In other words, we wish to detect the presence of the badge identifying
uniquement dans une zone A située à gauche du véhicule et non à droite du véhicule. only in zone A located to the left of the vehicle and not to the right of the vehicle.
Une solution connue pour résoudre ce problème consiste à émettre, à partir de deux points différents du véhicule, dont l'un est positionné de manière à couvrir principalement un côté du véhicule et dont l'autre est positionné de manière à couvrir principalement l'autre côté du véhicule, deux signaux successifs de méme intensité. Le badge identifiant reçoit successivement ces signaux avec des niveaux d'intensité différents, compte tenu de sa distance à chacun des deux points d'émission. Ainsi, le badge identifiant peut déterminer de quel côté du véhicule il se trouve en comparant l'intensité des deux signaux perçus et renvoyer ensuite au dispositif d'identification un signal indiquant non seulement A known solution to solve this problem consists in transmitting, from two different points of the vehicle, one of which is positioned so as to mainly cover one side of the vehicle and the other of which is positioned so as to mainly cover the other. side of the vehicle, two successive signals of the same intensity. The identifying badge successively receives these signals with different intensity levels, taking into account its distance from each of the two emission points. Thus, the identifying badge can determine which side of the vehicle it is on by comparing the intensity of the two perceived signals and then send back to the identification device a signal indicating not only
son identification mais également son positionnement. its identification but also its positioning.
Cette solution présente l'inconvénient qu'elle requiert la présence de moyens électroniques complexes dans le dispositif d'identification et dans le badge identifiant, notamment du fait qu'il faut que ce dernier soit capable de mesurer l'intensité de chaque signal reçu, de comparer les intensités de ces deux signaux et d'en déduire un signal de This solution has the drawback that it requires the presence of complex electronic means in the identification device and in the identifying badge, in particular because it must be able to measure the intensity of each signal received, to compare the intensities of these two signals and to deduce a signal from them
localisation à retourner au dispositif d'identification. location to be returned to the identification device.
En outre, I'envoi de deux demandes d'identification successives rallonge le temps de communication entre ie véhicule et le badge identifiant et retarde en conséquence la In addition, the sending of two successive identification requests lengthens the communication time between the vehicle and the identifying badge and consequently delays the
réaction du système de décondamnation mains libres. hands-free unlocking system reaction.
La présente invention vise à proposer un nouveau procédé qui ne présente pas les The present invention aims to propose a new process which does not have the
inconvénients rappelés ci-dessus.disadvantages mentioned above.
En particul ier, le procédé sel on l 'i nvention présente l'avantage qu'i l permet de conserver un badge identifiant conventionnel, c'est-à-dire ne comportant aucun moyen In particular, the method selected on the invention has the advantage that it makes it possible to keep a conventional identifier badge, that is to say comprising no means
particulier grâce auquel il pourrait se localiser par rapport au véhicule. particular thanks to which it could be located in relation to the vehicle.
La présente invention a pour objet un procédé pour déceler, dans une zone prédéterminée appartenant à un ensemble de zones contiguës, la présence d'un récepteur apte à se manifester sur réception d'un signal de reconnaissance, selon lequel on émet un tel signal de reconnaissance couvrant ladite zone prédéterminée, caractérisé en ce que, simultanément à l'émission du signal de reconnaissance, on émet un bruit The present invention relates to a method for detecting, in a predetermined area belonging to a set of contiguous areas, the presence of a receiver capable of manifesting itself on reception of a recognition signal, according to which such a signal is transmitted. recognition covering said predetermined area, characterized in that, simultaneously with the emission of the recognition signal, a noise is emitted
parasite dans les autres zones contiguës à la zone prédéterminée. parasite in the other areas contiguous to the predetermined area.
Le procédé selon l'invention revient donc à ajouter au signal émis dans le voisinage du véhicule, en vue de la reconnaissance du badge identifiant, un ou plusieurs autres signaux parasites qui ont pour but de gêner la réception du signal de reconnaissance dans les zones du véhicule dans lesquelles on ne souhaite pas trouver le badge identifiant. Ainsi, si le baUge identifiant se trouve dans la zone attendue, il perçoit le signal et The method according to the invention therefore amounts to adding to the signal transmitted in the vicinity of the vehicle, for the purpose of recognizing the identifying badge, one or more other spurious signals which have the aim of hampering the reception of the recognition signal in the areas of the vehicle in which you do not wish to find the identifying badge. Thus, if the identifying bar is in the expected area, it perceives the signal and
répond positivement à la demande d'identification. responds positively to the identification request.
Si, en revanche, le badge identifiant se trouve en-dehors de la zone attendue, soit il ne reçoit aucun signal car il est trop éloigné du véhicule, soit il se trouve au voisinage du véhicule mais dans une zone non appropriée, par exemple de l'autre côté du véhicule que la poignée man_uvrée et, dans ce cas, même s'il se trouve dans le champ couvert par le signal de reconnaissance, le brouillage par le bruit parasite l'empêche de recevoir ce signal de reconnaissance et donc, en toute hypothèse, le badge identifiant est incapable If, on the other hand, the identifying badge is outside the expected area, either it receives no signal because it is too far from the vehicle, or it is in the vicinity of the vehicle but in an unsuitable area, for example the other side of the vehicle that the handle maneuvered and, in this case, even if it is in the field covered by the recognition signal, interference by parasitic noise prevents it from receiving this recognition signal and therefore, in any event, the identifying badge is incapable
d'envoyer une réponse au dispositif d'identification. to send a response to the identification device.
Ainsi, grâce à l'invention, on peut facilement privilégier une zone de détection associée à une région du véhicule, sans pour cela modifier la structure du badge identifiant, ni même la structure du dispositif d'identification, car celui-ci se borne, comme dans l'état de la technique, à émettre un signal de reconnaissance et à recevoir un signal Thus, thanks to the invention, it is easy to favor a detection zone associated with a region of the vehicle, without for that modifying the structure of the identifying badge, or even the structure of the identification device, since the latter is limited, as in the state of the art, to transmit a recognition signal and to receive a signal
d' identificati on.identification.
En d'autres termes, I'invention consiste à ajouter aux signaux émis selon le procédé traditionnel, des signaux parasites supplémentaires écartant certaines zones indésirables In other words, the invention consists in adding to the signals transmitted according to the traditional method, additional spurious signals removing certain undesirable zones
du champ d'action des moyens de détection. of the field of action of the detection means.
Dans un mode de réalisation préféré, on n'émet le signal de reconnaissance que In a preferred embodiment, the recognition signal is only emitted
dans la zone attendue tandis qu'on émet le bruit dans toutes les zones indésirables. in the expected area while noise is emitted in all unwanted areas.
Toutefois, dans une variante plus simple, on peut aussi émettre le signal de reconnaissance dans tout le voisinage du véhicule, sans distinction de zone, et émettre, However, in a simpler variant, it is also possible to transmit the recognition signal throughout the vicinity of the vehicle, without distinction of zone, and to transmit,
en supplément, le bruit parasite dans toutes les zones indésirables. in addition, interference noise in all unwanted areas.
-4 Dans un mode de réalisation particulier de l'invention, le bruit parasite est constitué -4 In a particular embodiment of the invention, the parasitic noise consists
par un pur signal de porteuse.by a pure carrier signal.
Dans un autre mode de réalisation particulier de l'invention, compatible avec les précédents, le signal de reconnaissance est envoyé avec une intensité supérieure à celle du bruit parasite. La présente invention a également pour objet une application du procédé décrit ci dessus à la gestion d'un système mains libres de décondamnation de véhicule automobile In another particular embodiment of the invention, compatible with the previous ones, the recognition signal is sent with an intensity greater than that of the parasitic noise. The present invention also relates to an application of the method described above to the management of a hands-free system for unlocking a motor vehicle.
ainsi qu'un système mains libres de décondamnation mettant en _uvre ce procédé. as well as a hands-free unlocking system implementing this process.
Afin de faciliter la compréhension de l'invention, on va maintenant en décrire un mode de mise en _uvre à l'aide du dessin annexé dans lequel: la figure 1, déjà décrite, est illustrative de l'état de la technique, la figure 2 est une vue anaiogue à la figure 1 montrant l'intensité d'un signal de reconnaissance et d'un bruit parasite émis de l'autre côté du véhicule, - la figure 3 est une vue analogue à la figure 2 montrant une variante de mise en In order to facilitate understanding of the invention, we will now describe an implementation mode using the appended drawing in which: FIG. 1, already described, is illustrative of the state of the art, FIG. 2 is an analog view in FIG. 1 showing the intensity of a recognition signal and a parasitic noise emitted on the other side of the vehicle, - FIG. 3 is a view similar to FIG. 2 showing a variant of setting
_uvre de l'invention._work of the invention.
Sur la figure 2, on retrouve le véhicule 1 vu de dessus et le graphe de l'intensité 2 de signaux émis superposé au véhicule. Conformément à un mode de réalisation de l 'i nventi on, on reméd ie au risque de détection du badge i dentifi ant du mauvais côté du véhicule en émettant, dans une zone B (située majoritairement du côté droit du véhicule) In Figure 2, we find the vehicle 1 seen from above and the graph of the intensity 2 of transmitted signals superimposed on the vehicle. In accordance with an embodiment of the invention, the risk of detection of the dentifying badge on the wrong side of the vehicle is remedied by transmitting, in a zone B (located mainly on the right side of the vehicle)
un bruit parasite 5 qui vient brouiller le signal de reconnaissance précédemment décrit. a spurious noise 5 which interferes with the recognition signal described above.
Il en résulte que, même si le badge identifiant se trouve à proximité des portières droites du véhicule, dans le champ couvert par le signal de reconnaissance émis de l'autre côté du véhicule, ce badge identifiant ne percevra pas ledit signal de It follows that, even if the identifying badge is located near the right doors of the vehicle, in the field covered by the recognition signal emitted on the other side of the vehicle, this identifying badge will not perceive said signal
reconnaissance en raison du bruit parasite. recognition due to extraneous noise.
La sélectivité du système mains libres est donc obtenue sans aucune modification The selectivity of the hands-free system is therefore obtained without any modification
du dispositif d'identification ni du badge identifiant. the identification device or the identifying badge.
Pour garantir que le bruit ne perturbe pas la réception du signal de reconnaissance du bon côté du véhicule (ici le côté gauche), on peut prévoir de donner audit bruit une intensité plus faible que celle du signal de reconnaissance 2, afin de réduire la largeur de la zone B. To ensure that the noise does not disturb the reception of the recognition signal on the right side of the vehicle (here the left side), provision may be made to give said noise a lower intensity than that of the recognition signal 2, in order to reduce the width of zone B.
Ce bruit d'intensité plus faible est représenté par le trait interrompu 5' sur la figure 2. This lower intensity noise is represented by the broken line 5 ′ in FIG. 2.
Dans la variante représentée à la figure 3, les moyens d'identification émettent un signal de reconnaissance 6 couvrant tout le voisinage du véhicule et des moyens de brouillage émettent un signal parasite 5 ou 5' dans la zone B du véhicule dans laquelle In the variant shown in FIG. 3, the identification means emit a recognition signal 6 covering the entire vicinity of the vehicle and scrambling means emit a spurious signal 5 or 5 ′ in the zone B of the vehicle in which
on ne souhaite pas déceler le badge identifiant. we do not wish to detect the identifying badge.
Par diflérence, la région du véhicule dans laquelle on accepts de trouver le badge identifiant pour décondamner les portières correspond à la zone A recevant uniquement le By diflerence, the region of the vehicle in which one accepts to find the badge identifying to unlock the doors corresponds to zone A receiving only the
signal de reconnaissance et pas le bruit. recognition signal and not noise.
Il est bien entendu que les modes de mise en _uvre décrits ci-dessus ne présentent aucun caractère limitatif et qu'ils pourront recevoir toute modification souhaitable sans It is understood that the methods of implementation described above are in no way limiting and that they can receive any desirable modification without
sortir pour cela du cadre de l'invention. to go beyond the scope of the invention.
