Description

Système d'autorisation de démarrage main-libre pour un véhicule automobile par reconnaissance d'empreinte digitale et procédé associé  Hand-free start authorization system for a motor vehicle by fingerprint recognition and associated method
L'invention concerne un système de contrôle du démarrage d'un véhicule dont l'autorisation de démarrage ne nécessite pas d'intervention manuelle spécifique de la part de l'utilisateur. Plus spécifiquement, l'invention se rapporte à un système d'autorisation de démarrage main-libre pour un véhicule automobile par reconnaissance d'empreinte digitale et au procédé associé.  The invention relates to a system for controlling the starting of a vehicle whose start authorization does not require any specific manual intervention on the part of the user. More specifically, the invention relates to a hands-free start authorization system for a motor vehicle by fingerprint recognition and the associated method.
On connaît un système dit « main-libre » qui permet d'accéder à un véhicule et de démarrer celui-ci sans avoir à utiliser de clef mécanique. L'utilisateur du véhicule est simplement muni d'une clef électronique (appelée également 'badge'). Le véhicule est, pour sa part, équipé d'un dispositif d'authentification et de gestion associé à des antennes disposées à bord du véhicule. Ce dispositif est destiné à détecter la clef électronique à proximité du véhicule ou dans celui-ci pour ensuite déterminer, par le biais d'un dialogue avec ladite clef électronique, si cette dernière est une clef autorisée ou non pour le véhicule. Le porteur de la clef électronique, lorsque celle-ci est reconnue par le dispositif d'authentification, peut alors accéder à l'intérieur du véhicule et démarrer le moteur par une simple action sur un bouton, sans avoir à manipuler sa clef électronique.  We know a so-called "hands-free" system that allows access to a vehicle and start it without having to use a mechanical key. The user of the vehicle is simply provided with an electronic key (also called 'badge'). The vehicle is, for its part, equipped with an authentication and management device associated with antennas disposed on board the vehicle. This device is intended to detect the electronic key near the vehicle or in it to then determine, through a dialogue with said electronic key, if the latter is a key authorized or not for the vehicle. The holder of the electronic key, when it is recognized by the authentication device, can then access the interior of the vehicle and start the engine with a simple action of a button, without having to manipulate his electronic key.
Divers modes de réalisation de la fonction « accès / démarrage » sont disponibles sur la base de ce dispositif. Par exemple :  Various embodiments of the "access / start" function are available on the basis of this device. For example :
• Le badge, interrogé lorsque le porteur est à l'extérieur du véhicule, dialogue avec le dispositif d'authentification qui autorise l'accès au véhicule et le démarrage. Ce mode de réalisation n'est malheureusement pas sûr, une personne pouvant s'introduire à l'intérieur du véhicule automobile en lieu et place du porteur de la clef électronique et à démarrer tant que celui-ci est à proximité.  • The badge, interrogated when the wearer is outside the vehicle, dialog with the authentication device that allows access to the vehicle and start. This embodiment is unfortunately not safe, a person can be introduced inside the motor vehicle in place of the holder of the electronic key and start as it is nearby.
• Dans un mode de réalisation perfectionné, le badge est interrogé à l'extérieur du véhicule mais seule une autorisation de pénétrer à l'intérieur du véhicule est donnée en cas d'authentification du porteur de badge. Lorsque ledit porteur de badge souhaite ensuite démarrer et appuie sur le bouton de mise en marche, le dispositif d'authentification interroge alors de nouveau le badge, mais cette fois-ci avec des antennes couvrant l'intérieur du véhicule uniquement, ce qui garantit que le badge est bien à l'intérieur du véhicule. En cas d'authentification positive, le démarrage est autorisé. Cette solution est un peu plus sécurisante, mais en cas de vol du badge ou d'attaques par l'intermédiaire de relais radio, elle n'empêche aucunement le voleur de partir avec le véhicule.  • In an advanced embodiment, the badge is interrogated outside the vehicle but only an authorization to enter the vehicle is given in case of authentication of the badge wearer. When said badge carrier then wishes to start and press the start button, the authentication device then interrogates the badge again, but this time with antennas covering the inside of the vehicle only, which ensures that the badge is inside the vehicle. In case of positive authentication, startup is allowed. This solution is a little safer, but in case of theft of the badge or attacks via radio relay, it does not prevent the thief from leaving with the vehicle.
Ce sont ces inconvénients que la présente invention se propose de résoudre. These are the disadvantages that the present invention proposes to solve.
L'invention vise à fournir un système de contrôle du démarrage main-libre d'un véhicule qui soit moins exposé à un risque de piratage ou de fraude. Avec ces objectifs en vue, l'invention a pour objet un Système d'autorisation du démarrage main-libre d'un véhicule automobile comportant notamment un dispositif d'authentification embarqué dans le véhicule automobile et une clef électronique comportant un premier module alimenté électriquement apte à communiquer avec le dispositif d'authentification. Le système selon l'invention est remarquable en ce qu'il comporte en outre un dispositif de reconnaissance d'empreinte digitale apte à communiquer avec le dispositif d'authentification et comportant des moyens de mémorisation d'au moins une empreinte digitale autorisée, le dispositif d'authentification autorisant le démarrage du véhicule automobile lorsqu'il a reconnu l'empreinte digitale autorisée, puis identifié la présence du premier module à l'intérieur dudit véhicule. The aim of the invention is to provide a system for controlling the start-up of a vehicle which is less exposed to a risk of piracy or fraud. With these objectives in mind, the subject of the invention is a system for authorizing the start-up of a motor vehicle including, in particular, an authentication device embedded in the motor vehicle and an electronic key comprising a first electrically powered module capable of to communicate with the authentication device. The system according to the invention is remarkable in that it further comprises a fingerprint recognition device capable of communicating with the authentication device and comprising means for storing at least one authorized fingerprint, the device of authentication authorizing the starting of the motor vehicle when it recognized the authorized fingerprint, and identified the presence of the first module inside said vehicle.
Ainsi, grâce à l'invention, la sécurité du véhicule est renforcée en demandant, outre la reconnaissance du module alimenté, la reconnaissance de l'empreinte digitale d'un utilisateur autorisé avant toute autorisation de démarrage. L'empreinte digitale aura préalablement été enregistrée et lors de l'utilisation, l'empreinte de l'utilisateur est acquise et comparée à celle qui est enregistrée. Il va de soi que plusieurs empreintes peuvent être enregistrées si le véhicule peut être utilisé par plusieurs conducteurs différents. La reconnaissance de l'une des empreintes est l'événement déclencheur qui initie le processus d'authentification du premier module avant l'autorisation de démarrage du véhicule.  Thus, thanks to the invention, the security of the vehicle is enhanced by requesting, in addition to the recognition of the module supplied, the recognition of the fingerprint of an authorized user before any authorization to start. The fingerprint will have been previously recorded and during use, the fingerprint of the user is acquired and compared to that which is recorded. It goes without saying that several fingerprints can be recorded if the vehicle can be used by several different drivers. The recognition of one of the fingerprints is the triggering event that initiates the authentication process of the first module before the authorization to start the vehicle.
Selon un perfectionnement le système d'autorisation comporte en outre un bouton de démarrage intégrant le dispositif de reconnaissance d'empreinte digitale. En disposant le dispositif de reconnaissance d'empreinte digitale sur le bouton de démarrage, l'acquisition de l'empreinte peut se faire sans geste supplémentaire pour l'utilisateur. En effet, le démarrage du véhicule s'effectuant par l'appui sur un bouton avec un doigt, on profite de la présence du doigt contre une face du bouton pour réaliser l'acquisition de l'empreinte.  According to an improvement the authorization system further comprises a start button integrating the fingerprint recognition device. By arranging the fingerprint recognition device on the start button, acquisition of the fingerprint can be done without additional action for the user. Indeed, the start of the vehicle being carried out by pressing a button with a finger, it takes advantage of the presence of the finger against one side of the button to achieve the acquisition of the fingerprint.
Avantageusement, la communication entre le dispositif de reconnaissance d'empreinte digitale et le dispositif d'authentification est cryptée. Ainsi, le système ne peut pas être falsifié en se plaçant simplement entre le dispositif de reconnaissance d'empreinte digitale et le dispositif d'authentification.  Advantageously, the communication between the fingerprint recognition device and the authentication device is encrypted. Thus, the system can not be falsified simply by placing itself between the fingerprint recognition device and the authentication device.
Dans un autre mode de réalisation, le système d'autorisation de démarrage comporte en outre un deuxième module non alimenté électriquement apte à communiquer avec le dispositif d'authentification et venant se substituer au premier module et/ou au dispositif de reconnaissance d'empreinte digitale en cas de défaillance d'au moins un de ces deux. Ainsi, même si le premier module ou le système de reconnaissance d'empreinte digitale ne fonctionne pas, il reste un moyen de démarrer le véhicule.  In another embodiment, the start authorization system further comprises a second electrically unpowered module capable of communicating with the authentication device and replacing the first module and / or the fingerprint recognition device. in case of failure of at least one of these two. Thus, even if the first module or the fingerprint recognition system does not work, there remains a way to start the vehicle.
L'invention se rapporte également à un procédé d'autorisation du démarrage d'un véhicule automobile à l'aide d'une clef électronique, remarquable en ce qu'on autorise le démarrage du véhicule automobile si on identifie un utilisateur enregistré par la reconnaissance de son empreinte digitale et qu'ensuite on identifie un premier module alimenté électriquement de la clef électronique à l'intérieur dudit véhicule automobile. The invention also relates to a method for authorizing the starting of a motor vehicle with the aid of an electronic key, which is remarkable in that it authorizes the starting of the motor vehicle if a user registered by the vehicle is identified. recognition of its fingerprint and then identified a first electrically powered module of the electronic key inside said motor vehicle.
Avantageusement, on reconnaît l'empreinte digitale lorsque l'utilisateur place son doigt sur un bouton de démarrage du véhicule automobile.  Advantageously, the fingerprint is recognized when the user places his finger on a starter button of the motor vehicle.
De préférence, l'échange de données se fait de manière cryptée entre un dispositif de reconnaissance d'empreinte digitale apte à reconnaître une empreinte digitale et un dispositif d'authentification apte à autoriser le démarrage du véhicule automobile.  Preferably, the data exchange is encrypted between a fingerprint recognition device capable of recognizing a fingerprint and an authentication device capable of authorizing the starting of the motor vehicle.
Selon une variante, le dispositif d'authentification émet une demande d'authentification vers le premier module après avoir reconnu l'empreinte digitale.  According to one variant, the authentication device sends an authentication request to the first module after having recognized the fingerprint.
De manière subsidiaire, le procédé autorise en outre le démarrage du véhicule si on identifie un deuxième module non alimenté électriquement de la clef électronique et venant se substituer au premier module et/ou au dispositif de reconnaissance d'empreinte digitale en cas de défaillance d'au moins un de ces deux.  In a subsidiary manner, the method also allows the vehicle to be started if a second electrically unpowered module of the electronic key is identified and which replaces the first module and / or the fingerprint recognition device in the event of a failure. at least one of these two.
L'invention sera mieux comprise et d'autres particularités et avantages apparaîtront à la lecture de la description qui va suivre, la description faisant référence à la figure 1 qui est une vue schématique d'un système selon l'invention.  The invention will be better understood and other features and advantages will appear on reading the description which follows, the description referring to Figure 1 which is a schematic view of a system according to the invention.
Un système d'autorisation du démarrage selon l'invention est destiné à être installé en partie sur un véhicule, non représenté. Le système comporte en outre une clef électronique 1 destinée à être utilisée par un conducteur du véhicule.  A starting authorization system according to the invention is intended to be installed partly on a vehicle, not shown. The system further comprises an electronic key 1 for use by a driver of the vehicle.
La partie embarquée du système comporte un dispositif d'authentification 2, un lecteur 3 et un bouton 4 de démarrage. Le bouton 4 de démarrage comporte un dispositif de reconnaissance d'empreinte digitale 40. Le dispositif d'authentification 2 est relié par des liaisons filaires 5 au lecteur 3 d'une part, et au bouton 4 d'autre part. Les liaisons filaires 5 sont de préférence des liaisons numériques cryptées.  The embedded part of the system comprises an authentication device 2, a reader 3 and a start button 4. The start button 4 comprises a fingerprint recognition device 40. The authentication device 2 is connected by wire links 5 to the reader 3 on the one hand, and to the button 4 on the other hand. The wired links 5 are preferably encrypted digital links.
La clef électronique 1 comporte un premier module 11 alimenté par une pile, non représentée, apte à communiquer par ondes radio avec le dispositif d'authentification 2. Le premier module 11 permet de communiquer par un signal par voie hertzienne avec le dispositif d'authentification 2 afin d'autoriser l'accès au véhicule et son démarrage. Par ces échanges, un code d'authentification est également transmis au dispositif d'authentification 2, lequel compare le code transmis avec un code mémorisé. En cas de concordance du code d'authentification avec un code mémorisé par le dispositif d'authentification 2, le premier module est identifié.  The electronic key 1 comprises a first module 11 powered by a battery, not shown, able to communicate by radio waves with the authentication device 2. The first module 11 makes it possible to communicate by a radio signal with the authentication device 2 to allow access to the vehicle and its start. Through these exchanges, an authentication code is also transmitted to the authentication device 2, which compares the transmitted code with a stored code. In case of concordance of the authentication code with a code stored by the authentication device 2, the first module is identified.
La clef électronique 1 comporte également un deuxième module 12 incorporant un transpondeur non alimenté et contenant un code d'authentification. Lorsque la clef électronique 1 est placée dans le lecteur 3, ce dernier est apte à alimenter le transpondeur 12 par couplage électromagnétique et à lire le code d'authentification. En cas de concordance du code d'authentification avec un code mémorisé par le dispositif d'authentification 2, le démarrage du véhicule est autorisé. Le procédé conforme à l'invention est le suivant. The electronic key 1 also comprises a second module 12 incorporating a transponder that is not powered and contains an authentication code. When the electronic key 1 is placed in the reader 3, the latter is able to feed the transponder 12 by electromagnetic coupling and to read the authentication code. In case of matching of the authentication code with a code stored by the authentication device 2, the vehicle is allowed to start. The process according to the invention is as follows.
Dès que l'utilisateur pose son doigt sur le bouton 4 de démarrage, le dispositif de reconnaissance d'empreinte digitale 40 acquiert l'empreinte et la compare avec une ou plusieurs empreintes mémorisées. Si l'empreinte acquise concorde avec une empreinte mémorisée, le dispositif de reconnaissance d'empreinte digitale 40 transmet l'information de reconnaissance au dispositif d'authentification 2. Le dispositif d'authentification 2 interroge alors le premier module 1 1 au moyen d'antennes couvrant l'intérieur du véhicule. Si le premier module 11 est bien présent à l'intérieur du véhicule, il transmet alors un code d'authentification au dispositif d'authentification 2. Ce dernier compare le code transmis avec un code mémorisé. Si la comparaison indique que les codes concordent et que le premier module 11 est bien situé à l'intérieur du véhicule, le dispositif d'authentification 2 autorise alors le démarrage du moteur du véhicule automobile.  As soon as the user puts his finger on the start button 4, the fingerprint recognition device 40 acquires the impression and compares it with one or more stored impressions. If the acquired fingerprint matches a stored fingerprint, the fingerprint recognition device 40 transmits the recognition information to the authentication device 2. The authentication device 2 then interrogates the first module 1 1 by means of antennas covering the interior of the vehicle. If the first module 11 is present inside the vehicle, it then transmits an authentication code to the authentication device 2. The latter compares the transmitted code with a stored code. If the comparison indicates that the codes match and that the first module 11 is located inside the vehicle, the authentication device 2 then allows the engine to start the motor vehicle.
Ce mode d'authentification ne s'oppose pas à la reconnaissance de manière indépendante du deuxième module 12 à transpondeur qui est usuellement utilisé en mode de secours (mais qui peut être utilisé par un conducteur ne souhaitant pas utiliser la fonction main-libre). Ainsi, même si l'authentification du premier module 11 ou celle de l'empreinte digitale ne fonctionne pas, il est toujours possible d'utiliser le véhicule en plaçant la clef électronique 1 dans le lecteur 3 afin d'obtenir l'autorisation de démarrage du véhicule. Ce cas de figure se présente lorsque, par exemple, la pile du premier module 11 est déchargée ou enlevée ou bien encore lorsque la reconnaissance de l'empreinte digitale est rendue impossible (usage de gants, doigt tâché, dispositif de reconnaissance d'empreinte digitale 40 hors service, etc.).  This authentication mode does not preclude independent recognition of the second transponder module 12 which is usually used in emergency mode (but which can be used by a driver not wishing to use the main-free function). Thus, even if the authentication of the first module 11 or that of the fingerprint does not work, it is still possible to use the vehicle by placing the electronic key 1 in the reader 3 in order to obtain the authorization to start of the vehicle. This case occurs when, for example, the battery of the first module 11 is discharged or removed or even when the recognition of the fingerprint is made impossible (use of gloves, finger stained fingerprint recognition device 40 out of order, etc.).
De manière complémentaire, le système est agencé pour permettre l'effacement des empreintes enregistrées, et pour permettre la désactivation de la fonction de reconnaissance d'empreinte digitale. Ces fonctions sont par exemple réservées à un utilisateur principal du véhicule, reconnu par son empreinte. L'utilisateur principal est par exemple le premier qui a enregistré son empreinte. D'une autre manière, ces fonctions sont accessibles en plaçant le deuxième module 12 dans le lecteur 3 et en reconnaissant le transpondeur.  In a complementary manner, the system is arranged to allow erasure of the recorded fingerprints, and to enable the deactivation of the fingerprint recognition function. These functions are for example reserved for a main user of the vehicle, recognized by his footprint. The main user is for example the first one who has registered his fingerprint. In another way, these functions are accessible by placing the second module 12 in the reader 3 and recognizing the transponder.
II n'est pas forcément nécessaire de prévoir un bouton 4 de démarrage qui s'enfonce ou se déplace. Dès que l'empreinte est reconnue, l'information de reconnaissance est transmise au dispositif d'authentification qui interprète cette transmission comme une demande de démarrage. Le dispositif d'authentification interroge alors le premier module et commande le démarrage s'il effectue une authentification positive.  It is not necessarily necessary to provide a start button 4 that sinks or moves. As soon as the fingerprint is recognized, the recognition information is transmitted to the authentication device which interprets this transmission as a start request. The authentication device then interrogates the first module and commands the start if it performs a positive authentication.
