DESCRIPTION DESCRIPTION
Titre : Procédé et système de contrôle de démarrage d’un véhicule Domaine technique Title: Method and system for controlling the start of a vehicle Technical field
L’invention concerne un procédé et un système de contrôle de démarrage d’un véhicule, notamment de type automobile. L’invention concerne également un procédé et un système de contrôle de l’utilisation d’un ou plusieurs véhicules d’une flotte de véhicules. The invention relates to a method and a system for controlling the starting of a vehicle, in particular of the automobile type. The invention also relates to a method and a system for controlling the use of one or more vehicles of a vehicle fleet.
Arrière-plan technologique Technological background
De nouveaux usages associés aux véhicules, notamment aux véhicules automobiles, ont vu le jour ces dernières années. A titre d’exemple, des services d’autopartage ou de voitures en libre-service se sont développés. Grâce à de tels services, un ensemble de véhicules, aussi appelé flotte de véhicules, est mis à disposition de clients de sociétés ou associations gérant cet ensemble de véhicules. Cela signifie qu’un même véhicule de l’ensemble est amené à être utilisé par plusieurs utilisateurs différents. New uses associated with vehicles, in particular motor vehicles, have emerged in recent years. For example, carsharing or self-service car services have developed. Thanks to such services, a set of vehicles, also called a fleet of vehicles, is made available to customers of companies or associations managing this set of vehicles. This means that the same vehicle in the set will be used by several different users.
De la même manière, un particulier propriétaire d’un véhicule peut également décider de proposer son véhicule en location ou en autopartage. Pour qu’un utilisateur puisse profiter de ce service et utiliser un véhicule, il est nécessaire de faire parvenir la clé de contact permettant de démarrer le véhicule à cet utilisateur. La gestion de l’accès aux clés de contact s’avère ainsi coûteuse. Likewise, a private owner of a vehicle can also decide to offer his vehicle for rental or car sharing. In order for a user to take advantage of this service and use a vehicle, it is necessary to send the ignition key to start the vehicle to this user. This makes it expensive to manage access to the ignition keys.
Il est connu des solutions permettant à un utilisateur d’obtenir la clé sans l’intervention d’un tiers. Par exemple, il est connu de laisser la clé du véhicule dans un espace protégé et sécurisé du véhicule, par exemple dans la boîte à gant. Selon cette solution, il est nécessaire à l’utilisateur d’entrer un code ou de répondre à une ou plusieurs questions pour que l’accès à la clé lui soit autorisé. Malgré la mise en place de système de sécurité, des problèmes de vol ou de perte de clé peuvent apparaître ainsi que des problèmes liés au verrouillage de l’espace recevant la clé. Solutions are known which allow a user to obtain the key without the intervention of a third party. For example, it is known practice to leave the vehicle key in a protected and secure space of the vehicle, for example in the glove box. According to this solution, it is necessary for the user to enter a code or to answer one or more questions for access to the key to be authorized. Despite the installation of a security system, problems of theft or loss of the key may appear as well as problems related to the locking of the space receiving the key.

Un procédé et un dispositif de contrôle de démarrage d’un véhicule vont maintenant être décrits dans ce qui va suivre en référence conjointement aux figures 1 à 6. Des mêmes éléments sont identifiés avec des mêmes signes de référence tout au long de la description qui va suivre. A method and a device for controlling the start of a vehicle will now be described in what follows with reference in conjunction with Figures 1 to 6. The same elements are identified with the same reference signs throughout the description which follows. to follow.
Selon un exemple particulier et non limitatif de réalisation de l’invention, un procédé de contrôle de démarrage d’un moteur d’un véhicule comprend l’authentification d’un identifiant reçu d’un dispositif d’authentification. Un tel dispositif d’authentification correspond par exemple à un dispositif passif (par exemple un badge) ou à un dispositif de communication actif (par exemple un téléphone intelligent (de l’anglais « Smartphone ») configuré pour stocker en mémoire un tel identifiant. Un relais configuré pour alimenter en électricité au moins une partie d’un système électrique du véhicule est alors contrôlé en fonction du résultat de l’authentification, la partie du système électrique contrôlée en alimentation électrique via le relais comprenant un circuit d’alimentation du démarreur du véhicule. Le véhicule comprend avantageusement un moyen de démarrage comprenant un contacteur de démarreur et une clé de contact, la clé de contact étant insérée de manière inamovible dans le contacteur de manière qu’une rotation de la clé entraine un actionnement du démarreur pour démarrer le moteur. According to a particular and non-limiting example of an embodiment of the invention, a method of controlling the starting of a vehicle engine comprises the authentication of an identifier received from an authentication device. Such an authentication device corresponds for example to a passive device (for example a badge) or to an active communication device (for example a smart phone (standing for “Smartphone”) configured to store such an identifier in memory. A relay configured to supply electricity to at least a part of an electrical system of the vehicle is then controlled as a function of the result of the authentication, the part of the electrical system controlled for electrical supply via the relay comprising a starter power supply circuit. The vehicle advantageously comprises a starting means comprising a starter switch and an ignition key, the ignition key being inserted immovably in the switch so that a rotation of the key causes actuation of the starter to start engine.
L’utilisation d’un relais pour alimenter en électricité le démarreur du véhicule en fonction de l’authentification d’un identifiant permet d’autoriser l’utilisation du véhicule aux seules personnes porteuses d’un identifiant autorisant une telle utilisation. La clé de contact étant insérée de manière inamovible dans le contacteur, le contrôle de la mise sous tension du démarreur par authentification d’un identifiant permet d’éviter qu’une personne non autorisée utilise le véhicule, la clé de contact étant accessible dans le véhicule. Un tel système permet une mise à disposition sûre, simple et peu coûteuse d’un véhicule à toute personne autorisée (via un identifiant ad hoc). The use of a relay to supply the starter of the vehicle with electricity as a function of the authentication of an identifier makes it possible to authorize the use of the vehicle only to persons carrying an identifier authorizing such use. The ignition key being inserted in an irremovable manner in the contactor, the control of the energization of the starter by authentication of an identifier makes it possible to prevent an unauthorized person from using the vehicle, the ignition key being accessible in the vehicle. Such a system allows a safe, simple and inexpensive provision of a vehicle to any authorized person (via an ad hoc identifier).

Le moyen de démarrage 100 correspond à un contacteur de démarreur recevant dans un barillet du contacteur une clé de contact, la clé de contact étant insérée de manière inamovible dans le barillet du contacteur, de manière que la clé ne puisse pas être retirée du contacteur. Un tel moyen de démarrage permet de laisser la clé de contact dans le contacteur, ce qui simplifie le partage ou la location du véhicule. Un tel moyen de démarrage est décrit ci-après avec plus de détails en regard des figures 2, 3 et 4. Le contacteur du moyen de démarrage permet de fermer un circuit électrique du véhicule alimentée et commandée par la batterie du véhicule. Ce circuit électrique, lorsqu’il est fermé, permet d’alimenter deux bobines, dites de maintien et d’appel, d’un solénoïde, ce solénoïde correspondant à un électroaimant qui contrôle le démarrage du moteur électrique du démarreur 101 , lequel démarreur 101 permet de démarrer le moteur du véhicule. La fermeture du circuit électrique du véhicule alimentant le solénoïde est provoquée ou déclenchée lorsque la clé de contact insérée dans le contacteur est actionnée, c’est-à-dire tournée d’une position de repos vers une position de démarrage.The starting means 100 corresponds to a starter contactor receiving an ignition key in a cylinder of the contactor, the ignition key being inserted immovably in the cylinder of the contactor, so that the key cannot be withdrawn from the contactor. Such a starting means makes it possible to leave the ignition key in the ignition switch, which simplifies the sharing or the rental of the vehicle. Such a starting means is described below in more detail with reference to FIGS. 2, 3 and 4. The contactor of the starting means makes it possible to close an electrical circuit of the vehicle. powered and controlled by the vehicle battery. This electrical circuit, when it is closed, makes it possible to supply two coils, called holding and calling coils, of a solenoid, this solenoid corresponding to an electromagnet which controls the starting of the electric motor of the starter 101, which starter 101 allows you to start the vehicle's engine. The closing of the electrical circuit of the vehicle supplying the solenoid is caused or triggered when the ignition key inserted in the switch is actuated, that is to say turned from a rest position to a starting position.
Le dispositif 103 correspond par exemple à un calculateur du système embarqué du véhicule, par exemple une UCE (« Unité de Commande Electronique »). Un tel dispositif est décrit plus en détail en regard de la figure 5. The device 103 corresponds for example to a computer of the on-board system of the vehicle, for example an ECU (“Electronic Control Unit”). Such a device is described in more detail with reference to FIG. 5.
Le dispositif 103 est relié au dispositif 104 via une liaison filaire, par exemple via un bus de données de type CAN (de l’anglais « Controller Area Network » ou en français « Réseau de contrôleurs »), CAN FD (de l’anglais « Controller Area Network Flexible Data-Rate » ou en français « Réseau de contrôleurs à débit de données flexible »), FlexRay (selon la norme ISO 17458) ou Ethernet (selon la norme ISO/IEC 802.3). The device 103 is connected to the device 104 via a wired link, for example via a data bus of the CAN type (standing for “Controller Area Network”), CAN FD (for English “Controller Area Network Flexible Data-Rate” or in French “Network of controllers with flexible data rate”), FlexRay (according to the ISO 17458 standard) or Ethernet (according to the ISO / IEC 802.3 standard).
Selon une variante de réalisation, le dispositif 103 comprend le dispositif 104 pour ne former qu’un seul dispositif. According to an alternative embodiment, the device 103 comprises the device 104 to form only a single device.
Le dispositif 104 correspond par exemple à un lecteur de communication en champ proche ou à un récepteur radio de type Bluetooth® ou Wifi®, lequel dispositif étant configuré pour recevoir et/ou lire un identifiant (une clé virtuelle) stockée en mémoire du dispositif d’authentification 105. La communication en champ proche, dite CCP (ou NFC en langue anglaise, pour « Near-Field Communication »), est basée sur une technologie de communication sans fil à courte portée et à haute fréquence, par exemple 13,56 MFIz. Une telle technologie permet l’échange d’informations entre des périphériques jusqu’à une distance de quelques centimètres, par exemple 5 ou 10 cm.The device 104 corresponds for example to a near-field communication reader or to a radio receiver of the Bluetooth® or Wifi® type, which device being configured to receive and / or read an identifier (a virtual key) stored in the memory of the device. authentication 105. Near-field communication, known as CCP (or NFC in English, for “Near-Field Communication”), is based on short-range and high-frequency wireless communication technology, for example 13,56 MFIz. Such technology allows the exchange of information between devices up to a distance of a few centimeters, for example 5 or 10 cm.
Lorsque l’utilisateur du véhicule (par exemple une personne ayant loué le véhicule pour une durée déterminée ou un abonné d’un service d’autopartage) souhaite utiliser le véhicule, ce dernier présente le dispositif d’authentification 105 à proximité du dispositif 104 lorsque ce dernier correspond à un lecteur CCP. Le dispositif d’authentification 105 est configuré pour stocker un identifiant qui est lu par le dispositif 104 lorsque le dispositif d’authentification est suffisamment proche. When the user of the vehicle (for example a person who has rented the vehicle for a determined period or a subscriber of a car-sharing service) wishes to use the vehicle, the latter presents the authentication device 105 near the device 104 when the latter corresponds to a CCP reader. The authentication device 105 is configured to store an identifier which is read by device 104 when the authentication device is close enough.
Le dispositif d’authentification 105 correspond par exemple à un dispositif passif, par exemple une carte ou un badge, ou à un dispositif actif, par exemple un objet intelligent tel qu’un téléphone intelligent (de l’anglais « smartphone ») et/ou un objet connecté, par exemple une montre connectée. Le dispositif d’authentification 105 comprend dans un espace mémoire une ou plusieurs informations d’identification (aussi appelé identifiant dans le reste de la description) qui permet d’identifier et d’authentifier le dispositif d’authentification 105, et par la même occasion la personne portant ce dispositif d’authentification 105. La ou les informations d’identification sont par exemple stockée sous une forme sécurisée ou cryptée, par exemple dans le cadre d’une infrastructure à clé publique, dite PKI (de l’anglais « Public Key Infrastructure »). The authentication device 105 corresponds for example to a passive device, for example a card or a badge, or to an active device, for example a smart object such as a smart phone (standing for “smartphone”) and / or a connected object, for example a connected watch. The authentication device 105 comprises in a memory space one or more identification information (also called an identifier in the rest of the description) which makes it possible to identify and authenticate the authentication device 105, and at the same time the person wearing this authentication device 105. The identification information (s) are for example stored in a secure or encrypted form, for example in the context of a public key infrastructure, called PKI (from the English "Public Key Infrastructure ”).
Le relais 102 (aussi appelé contacteur) correspond par exemple à un relais électromécanique et est par exemple composé d’un électroaimant dont l’alimentation est contrôlée ou pilotée par le dispositif 103. Lorsque l’électroaimant est alimenté (par exemple en très basse tension, par exemple 12 V ou 24 V), ce dernier transmet une force à un système de commutation électrique qui est composé d’un ou plusieurs interrupteurs, appelés contacts. Le relais est par exemple de type monostable ou bistable. Selon une variante, le relais 102 correspond à un relais statique. The relay 102 (also called contactor) corresponds for example to an electromechanical relay and is for example composed of an electromagnet whose power supply is controlled or driven by the device 103. When the electromagnet is supplied (for example at very low voltage , for example 12 V or 24 V), the latter transmits a force to an electrical switching system which is composed of one or more switches, called contacts. The relay is for example of the monostable or bistable type. According to one variant, the relay 102 corresponds to a static relay.
Le relais 102 est arrangé dans le circuit électrique du véhicule de manière à contrôler l’alimentation du démarreur 101. Le relais 102 est par exemple arrangé entre le moyen de démarrage 100 et le démarreur 101 ou selon un autre exemple, au niveau du circuit électrique permettant d’alimenter le démarreur à partir de la batterie du véhicule. Le relais 102 permet ainsi de séparer le circuit de commande comprenant par exemple le dispositif 103 des circuits de puissance du véhicule comprenant le circuit d’alimentation du démarreur 101. The relay 102 is arranged in the electrical circuit of the vehicle so as to control the power supply to the starter 101. The relay 102 is for example arranged between the starting means 100 and the starter 101 or according to another example, at the level of the electrical circuit. allowing the starter to be powered from the vehicle battery. The relay 102 thus makes it possible to separate the control circuit comprising, for example, the device 103 from the power circuits of the vehicle comprising the supply circuit of the starter 101.
Le relais 102 en association avec le dispositif 103 permet ainsi de contrôler le démarrage du moteur du véhicule selon un processus comprenant les opérations décrites ci-dessous, ces opérations étant par exemple mises en œuvre par le dispositif Dans une première opération, un identifiant stocké dans un dispositif d’authentification 105 est reçu, par exemple par le dispositif 104 qui le transmet au dispositif 103. L’identifiant est par exemple reçu selon un mode de communication en champ proche, conformément à la norme ISO/CEI 18092 et/ou à la norme ISO/CEI 14443, selon une liaison sans fil à courte portée (par exemple inférieure à 10 cm) et à haute fréquence (par exemple dans la gamme de fréquence égale à 13,56 MHz). Selon une variante, l’identifiant est reçu selon un mode de communication sans fil conforme au standard Bluetooth® ou Wifi® (par exemple conforme au standard IEEE 802.11 a/b/g/n). L’identifiant reçu par le dispositif 103 est par exemple comparé à une liste d’identifiants stockés en mémoire du dispositif 103, chaque identifiant de la liste étant associé à une personne ayant le droit d’utiliser le véhicule (par exemple pendant une durée déterminée et/ou à une ou plusieurs dates déterminées). Une telle liste est par exemple reçue d’un serveur distant, par exemple du « cloud » (ou « nuage » en français), selon une liaison de type OTA (de l’anglais « over-the-air », ou en français « par voie aérienne »). La connexion de type OTA utilise par exemple un ou plusieurs protocoles de communication sans fil tels que Bluetooth®, Wi-Fi® (basé sur IEEE 802.11), LTE (de l’anglais « Long-Term Evolution » ou en français « Evolution à long terme »), LTE- Advanced (ou en français LTE-avancé). Si l’identifiant reçu du dispositif 104 correspond à un des identifiants de la liste alors l’authentification est réussie, ce qui signifie que l’utilisateur portant le dispositif d’authentification 105 a le droit d’utiliser le véhicule.The relay 102 in association with the device 103 thus makes it possible to control the starting of the engine of the vehicle according to a process comprising the operations described below, these operations being for example implemented by the device. In a first operation, an identifier stored in an authentication device 105 is received, for example by the device 104 which transmits it to the device 103. The identifier is for example received according to a near-field communication mode, in accordance with the ISO / IEC 18092 and / or ISO / IEC 14443 standard, using a short-range wireless link (for example less than 10 cm) and high frequency (for example in the frequency range equal to 13.56 MHz ). According to one variant, the identifier is received according to a wireless communication mode conforming to the Bluetooth® or Wifi® standard (for example conforming to the IEEE 802.11 a / b / g / n standard). The identifier received by the device 103 is for example compared with a list of identifiers stored in the memory of the device 103, each identifier of the list being associated with a person having the right to use the vehicle (for example for a determined period of time. and / or on one or more determined dates). Such a list is for example received from a remote server, for example from the "cloud" (or "cloud" in French), according to an OTA type link (from the English "over-the-air", or in French "By air"). The OTA type connection uses, for example, one or more wireless communication protocols such as Bluetooth®, Wi-Fi® (based on IEEE 802.11), LTE (standing for “Long-Term Evolution” in English or in French “Evolution to long term ”), LTE-Advanced (or in French LTE-advanced). If the identifier received from the device 104 corresponds to one of the identifiers in the list then the authentication is successful, which means that the user wearing the authentication device 105 has the right to use the vehicle.
Dans le cas contraire, l’authentification échoue et le processus prend fin, l’utilisateur portant le dispositif d’authentification 105 n’étant pas autorisé à utiliser le véhicule.Otherwise, authentication fails and the process ends, with the user wearing the 105 authentication device not authorized to use the vehicle.
Dans une deuxième opération, le relais 102 est contrôlé par le dispositif 103 en fonction du résultat de l’authentification réalisée dans la première opération. Ainsi, si l’authentification est positive, c’est-à-dire que l’authentification est réussie, alors le relais 102 est contrôlé de manière à alimenter tout ou partie du circuit électrique du véhicule à partir de la batterie du véhicule, notamment pour alimenter le démarreur 101 à partir de la batterie. In a second operation, the relay 102 is controlled by the device 103 based on the result of the authentication performed in the first operation. Thus, if the authentication is positive, that is to say that the authentication is successful, then the relay 102 is controlled so as to supply all or part of the electrical circuit of the vehicle from the battery of the vehicle, in particular to power the starter 101 from the battery.
A contrario, si l’authentification est négative, c’est-à-dire que l’authentification a échoué, le relais 102 est contrôlé de manière à bloquer ou empêcher l’alimentation du circuit électrique de la voiture par la batterie, et notamment pour bloquer l’alimentation du démarreur 101 à partir de la batterie. Conversely, if the authentication is negative, that is to say that the authentication has failed, the relay 102 is controlled so as to block or prevent the supply of the circuit. of the car by the battery, and in particular to block the supply of the starter 101 from the battery.
Selon une variante, le relais 102 est ouvert par défaut, c’est-à-dire que l’alimentation du circuit électrique de la voiture ou au minimum le circuit d’alimentation du démarreur 101 est bloquée. Ainsi, lorsque l’authentification échoue aucune commande n’est transmise au relais 102 qui maintient ainsi par défaut ses contacts ouverts. Les contacts du relais 102 sont contrôlés pour être fermés uniquement lorsque l’authentification réussit. According to a variant, the relay 102 is open by default, that is to say that the power supply to the electrical circuit of the car or at least the power supply circuit of the starter 101 is blocked. Thus, when the authentication fails, no command is transmitted to relay 102 which thus keeps its contacts open by default. The contacts of relay 102 are checked to be closed only when authentication is successful.
Dans une troisième opération, le démarreur est actionné à la suite d’un actionnement de la clé de contact dans le contacteur du démarreur. La troisième opération est postérieure à la deuxième opération et l’actionnement du démarreur n’est effective que si le démarreur est alimenté par la batterie à la suite du contrôle du relais 102, c’est à dire uniquement lorsque l’authentification de l’identifiant est positive. Lorsque l’authentification a échoué, un actionnement de la clé de contact dans le contacteur est sans effet car le démarreur 101 du véhicule n’est pas alimenté par la batterie, ce qui empêche le démarrage du moteur et toute utilisation du véhicule. In a third operation, the starter is actuated following actuation of the ignition key in the starter contactor. The third operation is subsequent to the second operation and the actuation of the starter is effective only if the starter is supplied by the battery following the control of the relay 102, that is to say only when the authentication of the identifier is positive. When authentication has failed, actuating the ignition key in the ignition switch has no effect because the vehicle's starter motor 101 is not powered by the battery, which prevents the engine from starting and any use of the vehicle.
Un tel processus permet ainsi de contrôler efficacement l’utilisation d’un véhicule en la restreignant aux seules personnes autorisées, même si la clé de contact reste à demeure accessible dans le véhicule au niveau du contacteur. [Fig. 2] illustre de façon schématique une vue en perspective du moyen de démarrage 100, selon un exemple de réalisation particulier et non limitatif de la présente invention. Such a process thus makes it possible to effectively control the use of a vehicle by restricting it to only authorized persons, even if the ignition key remains permanently accessible in the vehicle at the switch. [Fig. 2] schematically illustrates a perspective view of the starting means 100, according to a particular and non-limiting embodiment of the present invention.
[Fig. 3] illustre de façon schématique une vue en coupe du moyen de démarrage 100 dans un plan parallèle à un axe longitudinal ‘X’, selon un exemple de réalisation particulier et non limitatif de la présente invention. [Fig. 4] illustre de façon schématique une vue éclatée du moyen de démarrage 100, selon un exemple de réalisation particulier et non limitatif de la présente invention.[Fig. 3] schematically illustrates a sectional view of the starting means 100 in a plane parallel to a longitudinal axis "X", according to a particular and non-limiting embodiment of the present invention. [Fig. 4] schematically illustrates an exploded view of the starting means 100, according to a particular and non-limiting embodiment of the present invention.
La figure 2 illustre un moyen de démarrage 100 suivant l'invention, comportant un dispositif de démarrage 3 tel que représenté en figure 1 , avec un stator 30 dans lequel pivote un barillet 31 , une clé 2 dont la tige 21 rentre dans le barillet 31 et qui comporte une partie de préhension 20. Le moyen de démarrage 100 comporte en outre un capot 1 qui recouvre la partie de préhension 20 de la clé 2. Le capot 1 est maintenu au stator 30 à l'aide d'un moyen de maintien 4, coopérant avec une interface de maintien 14 (illustré en fig. 3) disposée sur le capot 1. La coopération entre le moyen de maintien 4 et l’interface de maintien 14 permet de bloquer en translation le capot 1 par rapport au stator 30 suivant une direction parallèle à l'axe de rotation X, pour éviter que ledit capot 1 ne s’éloigne du stator 30 et du barillet 31 , tout en permettant une rotation dudit capot 1 autour de cet axe de rotation X. Dans le mode de réalisation présenté dans les figures, le moyen de maintien 4 est fixé au stator 30. FIG. 2 illustrates a starting means 100 according to the invention, comprising a starting device 3 as shown in FIG. 1, with a stator 30 in which a barrel 31 pivots, a key 2 whose rod 21 fits into the barrel 31 and which includes a gripping part 20. The starting means 100 further comprises a cover 1 which covers the gripping part 20 of the key 2. The cover 1 is held on the stator 30 by means of a retaining means 4, cooperating with a retaining interface 14 (illustrated in FIG. 3) arranged on the cover 1. The cooperation between the retaining means 4 and the retaining interface 14 makes it possible to block the cover 1 in translation relative to the stator 30 in a direction parallel to the axis of rotation X, to prevent said cover 1 from moving away from the stator 30 and from the barrel 31, while allowing a rotation of said cover 1 around this axis of rotation X. In the embodiment presented in in the figures, the holding means 4 is fixed to the stator 30.
Ainsi avantageusement, le capot est bloqué en translation par la paroi de blocage et ne peut pas être retiré en tirant dessus pour l’éloigner du stator. La clé n’est donc pas accessible. Par contre, le capot peut être mis en rotation autour de l'axe de rotation de sorte à faire pivoter la clé insérée dans le barillet. La clé est donc sécurisée et ne peut être retirée. Le blocage est réalisé de manière simple, par mise en butée de l’épaulement contre la paroi de blocage. Thus, the cover is advantageously blocked in translation by the blocking wall and cannot be removed by pulling on it to move it away from the stator. The key is therefore not accessible. On the other hand, the cover can be rotated around the axis of rotation so as to cause the key inserted in the cylinder to pivot. The key is therefore secure and cannot be removed. Blocking is achieved in a simple manner, by abutting the shoulder against the blocking wall.
Comme illustré en figure 3 et 4, le capot 1 comporte à l'intérieur un espace intérieur 12 dans lequel la partie de préhension 20, illustré en pointillés, de la clé 2 s'insère. Cet espace 12 débouche sur une face d'insertion 13 du capot 1 par laquelle rentre la partie de préhension 20 dans cet espace 12. Le capot 1 comporte en outre des moyens de blocage en rotation de la partie de préhension 20 de la clé 2 autour de l'axe de rotation X de sorte que la rotation du capot 1 suivant cet axe X entraîne en rotation la clé 2 insérée dans le barillet 31. Par exemple, la forme de la section de cet espace intérieur 12 dans un plan perpendiculaire à l'axe de rotation X est de forme complémentaire à la section de la partie de préhension 20 de la clé 2 suivant ce même plan, avec un jeu très faible entre la partie de préhension 20 et les parois du corps 1 délimitant l’espace interne 12, par exemple inférieur à 1 mm. En variante, les dimensions de l’espace interne sont tel que la clé 2 est insérée à force dans l’espace interne 12, de sorte de ne pas avoir de jeu entre la partie de préhension 21 et le corps 1 lors de la rotation dudit corps 1. En autre variante, l'espace intérieur 12 peut comporter des nervures permettant de bloquer la partie de préhension 20 en rotation selon l'axe de rotation X relativement au capot 1. D'autres moyens connus de l'homme du métier peuvent être appliqués pour bloquer la rotation de la clé 2 relativement au corps 1. As illustrated in FIGS. 3 and 4, the cover 1 has inside an interior space 12 in which the gripping part 20, illustrated in dotted lines, of the key 2 is inserted. This space 12 opens onto an insertion face 13 of the cover 1 through which the gripping part 20 enters this space 12. The cover 1 further comprises means for locking the gripping part 20 of the key 2 in rotation around of the axis of rotation X so that the rotation of the cover 1 along this axis X rotates the key 2 inserted in the cylinder 31. For example, the shape of the section of this interior space 12 in a plane perpendicular to the 'axis of rotation X is of complementary shape to the section of the gripping part 20 of the key 2 along the same plane, with a very small clearance between the gripping part 20 and the walls of the body 1 delimiting the internal space 12 , for example less than 1 mm. As a variant, the dimensions of the internal space are such that the key 2 is forcibly inserted into the internal space 12, so as not to have any play between the gripping part 21 and the body 1 during the rotation of said body 1. In another variant, the interior space 12 may include ribs making it possible to block the gripping part 20 in rotation along the axis of rotation X relative to the cover 1. Other means known to those skilled in the art can be applied to block the rotation of the key 2 relative to the body 1.
Comme illustré en figure 3, le profil de cet espace interne 12 se réduit le long de l'axe de rotation X, en partant de la face d'insertion 13 et en s'éloignant de cette face 13.As illustrated in FIG. 3, the profile of this internal space 12 is reduced along the axis of rotation X, starting from the insertion face 13 and moving away from this face 13.
C'est à dire qu’au moins l'une des dimensions cet espace interne dans une direction perpendiculaire à l'axe de rotation X diminue en s'éloignant de la face d'insertion 13 vers l'intérieur de cet espace 12. Par exemple, comme illustré en figure 3, l'espace interne 12 a une forme générale de trapèze dans une coupe suivant un plan parallèle à l'axe de rotation X. La partie de préhension 20 de la clé 2 a une forme sensiblement complémentaire à la forme de l'espace interne 12. Cette disposition permet de coincer la clé 2 dans le capot 1 , et d’éviter qu’elle puisse être retirée en cassant l’extrémité du capot 1 située à l’opposé de la face d’insertion 13. That is to say that at least one of the dimensions of this internal space in a direction perpendicular to the axis of rotation X decreases as it moves away from the insertion face 13 towards the interior of this space 12. By example, as illustrated in Figure 3, the internal space 12 has the general shape of a trapezoid in a section along a plane parallel to the axis of rotation X. The gripping portion 20 of the key 2 has a shape substantially complementary to the shape of the internal space 12. This arrangement makes it possible to jam the key 2 in the cover 1, and to prevent it from being removed by breaking the end of the cover 1 located opposite the insertion face 13.
Comme illustré en figure 3 et 4, le capot 1 comporte un épaulement circulaire 14 autour de la face d'insertion 13, et un corps 11 s'étendant depuis la face d'insertion 13 dans une direction parallèle à l'axe de rotation X lorsque le capot 1 est maintenu par le moyen de maintien 4. Cet épaulement circulaire 14 forme une collerette autour de l'extrémité du corps 11 comportant la face d'insertion 13. Le cercle définit par l'épaulement 14 est centré sur l'axe de rotation X lorsque le capot 1 est maintenu au barillet 30 par le moyen de maintien 4, et est dans un plan perpendiculaire à cet axe de rotation X. As illustrated in Figures 3 and 4, the cover 1 comprises a circular shoulder 14 around the insertion face 13, and a body 11 extending from the insertion face 13 in a direction parallel to the axis of rotation X when the cover 1 is held by the holding means 4. This circular shoulder 14 forms a flange around the end of the body 11 comprising the insertion face 13. The circle defined by the shoulder 14 is centered on the axis of rotation X when the cover 1 is held on the barrel 30 by the holding means 4, and is in a plane perpendicular to this axis of rotation X.
Le moyen de maintien 4 comporte une bague 42 qui s'enfile sur le stator 30 qui est de forme cylindrique. La bague 42 dépasse du stator 30 dans une direction parallèle à l'axe de rotation X, devant la face avant dudit stator 30. C'est à dire qu'elle déborde devant la face avant du stator 30. Le moyen de maintien 4 comporte une paroi de blocage 40 à l'extrémité de la bague 42 située devant la face avant du stator 30, et qui comporte une ouverture circulaire 41 en vis-à-vis de ladite face avant. La paroi de blocage 40 est sensiblement perpendiculaire à l'axe de rotation X, distante de la face avant du stator 30, et l'ouverture circulaire 41 est centrée sur cet axe de rotation X. Le diamètre de cette ouverture circulaire 41 est légèrement supérieure, par exemple inférieur à 1 ou 2 millimètres, à la plus grande dimension du corps 11 dans une direction perpendiculaire à l'axe de rotation X de sorte que ledit corps 11 puisse traverser ladite ouverture 41 et pivoter autour de l'axe de rotation X sans être bloqué par les bords de cette ouverture circulaire 41. C'est à dire que la section du corps 11 s'inscrit dans un cercle de diamètre légèrement inférieur au diamètre de l'ouverture circulaire 41. Par contre, le diamètre du capot 1 au niveau de l'épaulement 14 est supérieur au diamètre de l'ouverture 41 , mais est inférieur au diamètre de la partie de la bague 42 qui dépasse devant la face avant du stator 30. Ainsi, le capot 1 est maintenu par rapport au stator 30 dans une direction parallèle à l'axe de rotation X par la coopération entre la paroi de blocage 40 du moyen de maintien 4 et l'épaulement 14 du corps 1 , mais le corps 1 peut pivoter autour de l'axe de rotation X. L’écartement entre la paroi de blocage 40 et le face avant du stator est choisie légèrement supérieur à l’épaisseur de l’épaulement, c’est-à-dire à la dimension de l’épaulement parallèlement à l’axe de rotation X, de sorte à limiter les frottements de l’épaulement 14 contre la paroi de blocage 40 et de la face avant du stator 30 contre la face d’insertion 13 du capot 1 lors de la rotation dudit capot 1. The retaining means 4 comprises a ring 42 which slides over the stator 30 which is cylindrical in shape. The ring 42 protrudes from the stator 30 in a direction parallel to the axis of rotation X, in front of the front face of said stator 30. That is to say that it protrudes in front of the front face of the stator 30. The holding means 4 comprises a blocking wall 40 at the end of the ring 42 located in front of the front face of the stator 30, and which has a circular opening 41 facing said front face. The blocking wall 40 is substantially perpendicular to the axis of rotation X, distant from the front face of the stator 30, and the circular opening 41 is centered on this axis of rotation X. The diameter of this circular opening 41 is slightly greater. , for example less than 1 or 2 millimeters, to the largest dimension of the body 11 in a perpendicular direction to the axis of rotation X so that said body 11 can pass through said opening 41 and pivot around the axis of rotation X without being blocked by the edges of this circular opening 41. That is to say that the section of the body 11 fits into a circle with a diameter slightly less than the diameter of the circular opening 41. On the other hand, the diameter of the cover 1 at the level of the shoulder 14 is greater than the diameter of the opening 41, but is less than the diameter. of the part of the ring 42 which protrudes in front of the front face of the stator 30. Thus, the cover 1 is held relative to the stator 30 in a direction parallel to the axis of rotation X by the cooperation between the locking wall 40 of the holding means 4 and the shoulder 14 of the body 1, but the body 1 can pivot about the axis of rotation X. The distance between the blocking wall 40 and the front face of the stator is chosen to be slightly greater than the thickness of the shoulder, i.e. the dimension of the shoulder para All together with the axis of rotation X, so as to limit the friction of the shoulder 14 against the locking wall 40 and of the front face of the stator 30 against the insertion face 13 of the cover 1 during the rotation of the said cover 1.
En plaçant la partie de préhension 20 de la clé 2 à l'intérieur du capot 1 , le capot 1 étant maintenu par le moyen de maintien 4 au stator 30 avec la tige 21 de la clé 2 dans le barillet 31 , la rotation autour de l'axe X du capot 1 permet de faire pivoter la clé 2, et donc de faire pivoter le barillet 31 par rapport au stator 30 entre une première position et une deuxième position. Par exemple, la première position correspond à une position d'arrêt du véhicule, dans lequel le véhicule est mis hors tension de sorte qu'aucun équipement électrique ne puisse être activé, et la deuxième position correspond à une position de mise en fonction du véhicule dans laquelle les équipements électriques peuvent être activés. Dans le cas d'un véhicule électrique, la deuxième position correspond à une position où le moteur électrique dudit véhicule peut être activé pour faire avancer le véhicule. Dans le cas d'un véhicule thermique, la clé 2 et le barillet 31 peuvent pivoter dans une troisième position correspondant à une position d'actionnement d'un démarreur lançant le moteur thermique. By placing the gripping part 20 of the key 2 inside the cover 1, the cover 1 being held by the retaining means 4 to the stator 30 with the rod 21 of the key 2 in the barrel 31, the rotation around the X axis of the cover 1 enables the key 2 to be pivoted, and therefore the barrel 31 to be pivoted relative to the stator 30 between a first position and a second position. For example, the first position corresponds to a stop position of the vehicle, in which the vehicle is switched off so that no electrical equipment can be activated, and the second position corresponds to a position where the vehicle is switched on. in which electrical equipment can be activated. In the case of an electric vehicle, the second position corresponds to a position where the electric motor of said vehicle can be activated to move the vehicle forward. In the case of a thermal vehicle, the key 2 and the cylinder 31 can pivot into a third position corresponding to an actuation position of a starter launching the thermal engine.
Dans la figure 4, le corps 11 du capot 1 est de forme cylindrique de section générale circulaire avec deux méplats, les deux méplats s'étendant dans la longueur du corps 11. Les deux méplats sont situés de part et d'autre de l'axe de rotation X. Ils permettent une meilleure prise en main du capot 1 pour le faire pivoter autour de l'axe de rotation X. L’un des méplats peut comporter des inscriptions, par exemple indiquant la manœuvre a réalisé pour démarrer le véhicule, ou d'autres inscriptions. En variante, pour améliorer la prise en main du capot, l'un des méplats peut comporter une zone en creux. In Figure 4, the body 11 of the cover 1 is cylindrical in general circular section with two flats, the two flats extending in the length of the body 11. The two flats are located on either side of the axis of rotation X. They allow a better grip of the cover 1 to make it pivot about the axis of rotation X. One of the flats may include inscriptions, for example indicating the maneuver carried out to start the vehicle, or other inscriptions. As a variant, to improve the grip of the cover, one of the flats may include a recessed area.
Le stator 30 comporte sur sa surface latérale des crochets 32, par exemple 2, en saillie de la surface latérale 34 du stator 30, correspondant à la surface cylindrique du stator, dont le profil dans une direction parallèle à l'axe de rotation X forme une pente s'éloignant dudit stator 30 dans une direction opposée à la face avant, et formant à son extrémité une marche avec la surface latérale 34. La bague 42 comporte des ouvertures de fixation 43 en vis-à-vis de ces crochets 32. La bague 42 est enfilée autour du stator 30 par translation dans une direction parallèle à l'axe de rotation X depuis la face avant dudit stator 30, jusqu'à ce que les ouvertures de fixation 43 de la bague 42 viennent en vis-à-vis des crochets 32. La forme du profil des crochets 32 permet un écartement de la paroi de la bague 42 lors de son enfilement, par glissement sur la pente, jusqu'à ce que les crochets 32 rentrent dans les ouvertures de fixation 42, bloquant alors l'extraction de la bague 32 dans un mouvement inverse grâce à l'interaction entre ces crochets 32, et plus particulièrement la marche créée par ces crochets, et les bords des ouvertures de fixation 42. The stator 30 comprises on its lateral surface hooks 32, for example 2, projecting from the lateral surface 34 of the stator 30, corresponding to the cylindrical surface of the stator, the profile of which in a direction parallel to the axis of rotation X forms a slope moving away from said stator 30 in a direction opposite to the front face, and forming at its end a step with the lateral surface 34. The ring 42 has fixing openings 43 facing these hooks 32. The ring 42 is threaded around the stator 30 by translation in a direction parallel to the axis of rotation X from the front face of said stator 30, until the fastening openings 43 of the ring 42 face each other. screws of the hooks 32. The shape of the profile of the hooks 32 allows a separation of the wall of the ring 42 during its threading, by sliding on the slope, until the hooks 32 enter the fixing openings 42, blocking then the extraction of the ring 32 in a motion ment inversely thanks to the interaction between these hooks 32, and more particularly the step created by these hooks, and the edges of the fastening openings 42.
Dans les figures, le stator 30 est de forme cylindrique à section circulaire. Pour assurer un positionnement angulaire de la bague 42 par rapport au stator 30 selon l'axe du cylindre formé par le stator 30, qui est parallèle à l’axe de rotation X, le stator 30 comporte un pion 33 en saillie de la surface latérale 34 du stator 30, et la bague 42 comporte une rainure 44 parallèle à l'axe de rotation X et coopérant avec ledit pion 33. L'enfilement de la bague 42 autour du stator 30 jusqu'à la position désirée n'est possible que lorsque le pion 33 rentre dans la rainure 44 au moment du coulissement de la bague 42 autour du stator 30. In the figures, the stator 30 is cylindrical in shape with a circular section. To ensure angular positioning of the ring 42 relative to the stator 30 along the axis of the cylinder formed by the stator 30, which is parallel to the axis of rotation X, the stator 30 comprises a pin 33 projecting from the lateral surface 34 of the stator 30, and the ring 42 has a groove 44 parallel to the axis of rotation X and cooperating with said pin 33. The threading of the ring 42 around the stator 30 to the desired position is only possible when the pin 33 enters the groove 44 when the ring 42 slides around the stator 30.
Dans le mode de réalisation présentée dans les figures 3 et 4, l'axe de rotation du barillet 32 et donc de la clé 2 et du capot 1 n'est pas confondu avec l’axe du stator 30.In the embodiment shown in Figures 3 and 4, the axis of rotation of barrel 32 and therefore of key 2 and cover 1 is not coincident with the axis of stator 30.
La partie du moyen de maintien 4 qui déborde devant la face avant du stator 30 est de section circulaire centrée sur l'axe de rotation X, tandis que la bague 42 est un de forme cylindrique à section circulaire dont l’axe est confondu avec l’axe du cylindre formé par le stator 30. Le diamètre de la partie du moyen de maintien 4 débordant de la face avant peut être supérieur au diamètre de la partie de la bague 32 enfilée sur le stator 30, par exemple en fonction du diamètre de l'épaulement 14 du capot 1. The part of the retaining means 4 which protrudes in front of the front face of the stator 30 is of circular section centered on the axis of rotation X, while the ring 42 is of a cylindrical shape with a circular section whose axis coincides with the 'axis of the cylinder formed by the stator 30. The diameter of the part of the retaining means 4 projecting from the front face may be greater than the diameter of the part of the ring 32 threaded onto the stator 30, for example depending on the diameter of the shoulder 14 of the cover 1.
En variante, les deux axes du stator et de rotation peuvent être confondus. Comme illustré en figure 4, le stator 30 et le moyen de maintien 4 sont disposés derrière une garniture 5 de manière à les cacher, un trou d'accès dans ladite de garniture 5 laissant passer uniquement le capot 1. Le trou d'accès peut être de dimension très proche des dimensions de l'ouverture 41 du moyen de maintien 4 de manière à ce qu'en cas d'arrachement du moyen de maintien 4 du stator 30, le capot 1 soit bloqué, avec éventuellement le moyen de maintien 4, par la garniture 5. En variante, la partie de la garniture 5 située autour du trou d’accès est mise en contact contre le moyen de maintien 4 de sorte à renforcer la sécurité en rendant plus difficile l’arrachement du moyen de maintien 4. As a variant, the two axes of the stator and of rotation can be merged. As illustrated in Figure 4, the stator 30 and the retaining means 4 are arranged behind a gasket 5 so as to hide them, an access hole in said gasket 5 allowing only the cover 1. The access hole can pass. be of dimensions very close to the dimensions of the opening 41 of the retaining means 4 so that in the event of the retaining means 4 being pulled out of the stator 30, the cover 1 is blocked, possibly with the retaining means 4 , by the gasket 5. As a variant, the part of the gasket 5 located around the access hole is brought into contact against the retaining means 4 so as to reinforce the security by making it more difficult to tear off the retaining means 4 .
En variante, le moyen de maintien 4 fait partie de la garniture 5 qui fixée à un élément de structure du véhicule, comme par exemple un support de colonne de direction, sur lequel est fixé le stator 30. Le moyen de maintien 4 est dans ce cas fixé indirectement au stator 30 via l'élément de structure. As a variant, the retaining means 4 forms part of the trim 5 which is fixed to a structural element of the vehicle, such as for example a steering column support, on which the stator 30 is fixed. The retaining means 4 is in this. case indirectly fixed to the stator 30 via the structural element.
Le capot 1 est par exemple réalisé par la technologie d'impression en trois dimensions, connu sous le nom d'impression 3D, utilisant de la matière plastique ou encore d'autres matériaux. D'autres moyens de production connus de l'homme du métier peuvent être utilisés.

Other means of production known to those skilled in the art can be used.
Les figures illustrent un capot 1 comportant un corps 11 cylindrique s'étendant suivant l'axe de rotation X. D'autres formes du corps 11 peuvent être appliquées. Par exemple, le corps 11 peut être de forme conique se rétrécissant en s'éloignant du stator 30, ou avoir des formes plus complexes. Les formes pourront être choisies de manière à permettre d'insérer le capot au travers de l'ouverture 41 du moyen de maintien 4 avant de fixer ledit moyen de maintien au stator 30. The figures illustrate a cover 1 comprising a cylindrical body 11 extending along the axis of rotation X. Other shapes of the body 11 can be applied. For example, the body 11 can be of conical shape narrowing away from the stator 30, or have more complex shapes. The shapes may be chosen so as to allow the cover to be inserted through the opening 41 of the retaining means 4 before fixing said retaining means to the stator 30.
La mise en place du capot 1 et du moyen de maintien 4 est réalisé par exemple dans l'ordre suivant : - étape A : insertion de la clé 2 dans le barillet 31 The fitting of the cover 1 and of the retaining means 4 is carried out for example in the following order: - step A: insertion of key 2 in cylinder 31
- étape B : insertion du capot 1 au travers de l'ouverture 41 jusqu'à ce que l'épaulement 14 vienne en butée contre la paroi de blocage 40, l'insertion se faisant du côté de la bague 42, - step B: insertion of the cover 1 through the opening 41 until the shoulder 14 abuts against the blocking wall 40, the insertion being made on the side of the ring 42,
- étape C : fixation du moyen de maintien 3 équipé du capot 1 au barillet, par exemple par enfilement sur le barillet 30 de la bague 42 jusqu'à ce que les ouvertures de fixation 43 se placent en vis-à-vis des crochets 32 dans le cas du mode de réalisation présenté dans les figures. - step C: fixing of the retaining means 3 equipped with the cover 1 to the barrel, for example by threading on the barrel 30 of the ring 42 until the fixing openings 43 are placed vis-à-vis the hooks 32 in the case of the embodiment shown in the figures.
En variante, l'étape A peut-être réalisée à entre l'étape B et l'étape C. As a variant, step A can be carried out between step B and step C.
