DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne le domaine de l'accès à un véhicule et aux informations dudit véhicule à l'aide d'un téléphone de type ordiphone, et vise plus particulièrement un accès sécurisé au véhicule et aux données du véhicule.The present invention relates to the field of access to a vehicle and to the information of said vehicle using a telephone of the smartphone type, and is more particularly aimed at secure access to the vehicle and to the data of the vehicle.

ETAT DE LA TECHNIQUESTATE OF THE ART

Les fonctionnalités multiples des téléphones portables de type ordiphone ont ouvert des possibilités de communication et de connexion avec les véhicules automobile, tant au niveau de l'accès physique au véhicule qu'aux données de localisation et/ou de fonctionnement (état des pneumatiques, niveau de carburant,...). Toutefois, le contrôle d'un véhicule à l'aide d'un téléphone peut poser des problèmes de sécurité, et il est nécessaire de s'entourer de précautions pour l'authentification du demandeur d'accès via son téléphone.The multiple functionalities of cell phones of the smartphone type have opened up possibilities for communication and connection with motor vehicles, both in terms of physical access to the vehicle and to location and/or operating data (condition of tires, level fuel,...). However, the control of a vehicle using a telephone can pose security problems, and it is necessary to surround oneself with precautions for the authentication of the applicant for access via his telephone.

Il est connu l'utilisation de badge sans contact ou badge « mains libres » pour le verrouillage / déverrouillage de véhicule permettant également de démarrer le véhicule, de tels badge utilisant une technologie de type radiofréquence. La demande FR2700625 déposée au nom du demandeur en est un exemple.It is known to use contactless badges or “hands-free” badges for locking/unlocking the vehicle, also allowing the vehicle to be started, such badges using radio frequency type technology. Requirement FR2700625 filed on behalf of the plaintiff is an example.

Il est également connu, par le document GB2402840 , un appairage entre un téléphone et une clé physique d'accès à un véhicule permettant au téléphone d'être utilisé en tant que clé virtuelle pour accéder au véhicule.It is also known, from the document GB2402840 , a pairing between a phone and a physical vehicle access key allowing the phone to be used as a virtual key to access the vehicle.

WO2012041885 A1 décrit un procédé d'appairage d'un téléphone mobile avec un véhicule automobile, ledit téléphone mobile apparié pouvant être utilisé pour le verrouillage/déverrouillage et/ ou le démarrage dudit véhicule automobile à l'aide d'au moins une partie d'un code d'authentification, caractérisé en ce que l'on charge le téléphone mobile, avec ladite au moins une partie du code d'authentification nécessaire au verrouillage/déverrouillage et/ou au démarrage dudit véhicule automobile. WO2012041885 A1 describes a method for pairing a mobile telephone with a motor vehicle, said paired mobile telephone being able to be used for locking/unlocking and/or starting said motor vehicle using at least part of a code authentication, characterized in that the mobile phone is loaded with said at least part of the authentication code necessary for locking/unlocking and/or starting said motor vehicle.

Il est également connu, par le document FR2965434 un procédé d'appairage d'un téléphone mobile avec un véhicule, par l'intermédiaire d'une clé de verrouillage / déverrouillage appairée en usine avec le véhicule via le protocole NFC afin de permettre une condamnation /déverrouillage du véhicule par le téléphone à l'aide du protocole NFC.It is also known, from the document FR2965434 a method for pairing a mobile telephone with a vehicle, by means of a locking/unlocking key paired in the factory with the vehicle via the NFC protocol in order to allow locking/unlocking of the vehicle by the telephone at the using the NFC protocol.

Il est toutefois nécessaire, dans ces cas, de se trouver à proximité du véhicule afin de le contrôler, ce qui limite les possibilités d'utilisation.It is however necessary, in these cases, to be close to the vehicle in order to control it, which limits the possibilities of use.

La présente invention propose un procédé basé sur la technologie NFC utilisant une carte de faible encombrement, de type carte bancaire portant les moyens d'authentification, et pouvant s'appairer avec un téléphone portable afin de permettre les services de contrôle du véhicule à distance, c'est-à-dire sans que ce dernier ne soit à proximité du téléphone, ainsi que différents services tels que :

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La présente invention se propose d'utiliser la technologie et le protocole NFC dans un badge 2 de format peu encombrant, type carte bancaire, ledit badge permettant un accès direct au véhicule 4, tel qu'il est connu dans le domaine. Selon l'invention, le badge contient également une clé d'authentification, sous la forme du code VIN (pour « Vehicle Identification Number ») du véhicule, ce code unique donné à chaque véhicule, apparaît sur le châssis du véhicule. Ce code unique permet de sécuriser l'identification d'un utilisateur potentiel, ce dernier étant alors reconnu comme possesseur d'une « clé » et pouvant donc interagir avec le véhicule via une application sur son ordiphone. Ce code VIN est utilisé pour un accès à distance à un serveur 6. Cet accès est réalisé par un téléphone portable ou ordiphone 8 disposant également de la technologie NFC. Le code VIN est illisible directement par un ordiphone, mais qui peut être déchiffré par un serveur dédié qui a la clé pour lire le code VIN.The present invention proposes to use NFC technology and protocol in a badge 2 of compact format, bank card type, said badge allowing direct access to the vehicle 4, as it is known in the field. According to the invention, the badge also contains an authentication key, in the form of the VIN code (for “Vehicle Identification Number”) of the vehicle, this unique code given to each vehicle, appears on the chassis of the vehicle. This unique code makes it possible to secure the identification of a potential user, the latter then being recognized as the owner of a “key” and therefore able to interact with the vehicle via an application on his smartphone. This VIN code is used for remote access to a server 6. This access is achieved by a mobile phone or smartphone 8 also having NFC technology. The VIN code cannot be read directly by a smartphone, but can be deciphered by a dedicated server which has the key to read the VIN code.

Par ailleurs, le serveur 6 peut communiquer avec le véhicule 4 par toute technologie connue, et notamment via les réseaux selon les normes 2G/3G disponibles. La liaison est de type http sécurisée. Des pare-feux permettent d'accroître la sécurisation des échanges entre la voiture et le serveur.Furthermore, the server 6 can communicate with the vehicle 4 by any known technology, and in particular via the networks according to the 2G/3G standards available. There connection is of the secure http type. Firewalls make it possible to increase the security of exchanges between the car and the server.

Ainsi selon l'invention, le badge 2 est un objet physique qui permet de garder le contrôle sur le véhicule. Sans lui, il n'est notamment pas possible de démarrer le véhicule. Toutefois, l'ordiphone permet de créer une passerelle sécurisée pour accéder aux données du véhicule et offrir l'équivalent du badge, mais à distance.Thus according to the invention, the badge 2 is a physical object which makes it possible to maintain control over the vehicle. Without it, it is notably not possible to start the vehicle. However, the smartphone makes it possible to create a secure gateway to access vehicle data and offer the equivalent of the badge, but remotely.

On utilise donc une carte peu chère pour sécuriser l'authentification de l'ordiphone 8 permettant un accès au véhicule 4 à distance via l'ordiphone 8 et un serveur distant 6. Une application spécifique doit préalablement être chargée sur l'ordiphone 8 pour l'accès au serveur 6 et pour l'affichage des différentes données et réglages.An inexpensive card is therefore used to secure the authentication of the smartphone 8 allowing remote access to the vehicle 4 via the smartphone 8 and a remote server 6. A specific application must first be loaded on the smartphone 8 for the access to the server 6 and for displaying the various data and settings.

Afin de sécuriser davantage les accès au véhicule et à ses données, il peut être prévu deux niveaux d'accès, une fois l'appairage effectué entre le badge 2 et l'ordiphone 8 :

  • l'un sans code pour tout les informations concernant les données d'état du véhicule (pressions, niveaux,...)
  • l'autre avec un code PIN concernant des informations plus confidentielles de fonctionnement du véhicule : localisation du véhicule, ouverture / fermeture, démarrage... qui pourrait être déclenché à distance (pour faire monter quelqu'un dans la voiture,...)
In order to further secure access to the vehicle and its data, two levels of access can be provided, once the pairing has been carried out between the badge 2 and the smartphone 8:
  • one without code for all the information concerning the vehicle status data (pressures, levels,...)
  • the other with a PIN code concerning more confidential information on the operation of the vehicle: location of the vehicle, opening / closing, starting, etc. which could be triggered remotely (to get someone into the car, etc.)

Ainsi, un mode de mise en oeuvre de l'invention peut suivre l'enchaînement des étapes illustrées aux figures 2a à 2d :

  • Présence physique nécessaire du badge 2 et de l'ordiphone 8 (figure 2a), une application 20 spécifique à l'accès aux données envisagé ayant été chargée dans l'ordiphone,
  • Appairage de l'ordiphone 8 et du badge 2, par exemple en les plaquant l'un contre l'autre (figure 2b), la technologie NFC nécessitant que les deux éléments à appairer soient très proches l'un de l'autre,
  • Lancement automatique du programme spécifique avec connexion téléphonique au serveur 6, reconnaissance par ce dernier de la clé d'authentification (code VIN du véhicule) transmise par le badge 2 lors de l'appairage à l'ordiphone 8 et transmission d'un premier lot 10 de données a, b, c à l'ordiphone 8 qui les affiche par l'intermédiaire du programme (figure 2c).
Thus, an embodiment of the invention can follow the sequence of steps illustrated in figures 2a to 2d :
  • Physical presence of badge 2 and smartphone 8 required ( figure 2a ), an application 20 specific to the envisaged data access having been loaded into the smartphone,
  • Pairing of smartphone 8 and badge 2, for example by pressing them against each other ( figure 2b ), NFC technology requiring the two elements to be paired to be very close to each other,
  • Automatic launch of the specific program with telephone connection to the server 6, recognition by the latter of the authentication key (VIN code of the vehicle) transmitted by the badge 2 during pairing with the smartphone 8 and transmission of a first batch 10 of data a , b, c to the smartphone 8 which displays them via the program ( figure 2c ).

En effet, le véhicule automobile 4 comprend notamment un calculateur apte à transmettre des données d'état du véhicule, de position et de personnalisation au serveur 6, ainsi que recevoir, dudit serveur, des ordres et consignes de fonctionnement via les réseaux téléphoniques adéquats.Indeed, the motor vehicle 4 comprises in particular a computer capable of transmitting vehicle state, position and personalization data to the server 6, as well as receiving, from said server, operating orders and instructions via the appropriate telephone networks.

Ce premier lot de données concerne des données qui sont jugées comme non-confidentielles pour le propriétaire du véhicule, tel que le kilométrage, le niveau de carburant ou le niveau de charge pour un véhicule électrique, la température, et, plus généralement, l'état des lieux du véhicule (pression pneus, niveaux des liquides, état d'usures....).

  • Dans un deuxième temps, pour des fonctions sécurisées plus avancées, liées au fonctionnement du véhicule, et notamment pour une commande à distance de certaines fonctionnalités du véhicule, il est nécessaire de rentrer un code 12 sur l'ordiphone 8, pour les fonctions ci-dessous, cette liste n'étant pas exhaustive :
    • ∘ Géolocalisation du véhicule,
    • ∘ Démarrage / arrêt du moteur,
    • ∘ Climatisation,
    • ∘ Ouverture/fermeture du véhicule,
    • ∘ Réglage des positions de sièges, radio, annuaire téléphonique,...
This first batch of data concerns data which are deemed to be non-confidential for the owner of the vehicle, such as the mileage, the fuel level or the level of charge for an electric vehicle, the temperature, and, more generally, the inventory of the vehicle (tire pressure, fluid levels, state of wear, etc.).
  • Secondly, for more advanced secure functions, linked to the operation of the vehicle, and in particular for remote control of certain vehicle functions, it is necessary to enter a code 12 on the smartphone 8, for the functions below. below, this list is not exhaustive:
    • ∘ Vehicle geolocation,
    • ∘ Engine start / stop,
    • ∘ Air conditioning,
    • ∘ Opening/closing of the vehicle,
    • ∘ Adjustment of seat positions, radio, telephone book,...

Le serveur 6 peut alors communiquer un deuxième lot 14 de données d, e, f, et, si l'utilisateur le désire, peut, via la liaison privilégiée avec le véhicule, agir sur ce dernier, soit pour pré-régler des positions de sièges, de conduite, de stations de radio, d'agenda téléphonique, voire de pré-chauffage de l'intérieur de l'habitacle, ou pour verrouiller / déverrouiller l'accès au véhicule pour une personne qui se trouve à proximité.The server 6 can then communicate a second batch 14 of data d, e, f, and, if the user wishes, can, via the privileged link with the vehicle, act on the latter, either to pre-adjust positions of seats, driving, radio stations, telephone diary, even pre-heating the interior of the passenger compartment, or to lock / unlock access to the vehicle for a person who is nearby.

Par la présente invention, il est alors possible de gérer simplement non seulement l'ouverture et la fermeture de son véhicule à une distance hors de portée des liaisons sans fil directes (une centaine de mètres) mais également le démarrage du moteur du véhicule, et le déblocage de tous les dispositifs de protection contre le vol (blocage de la colonne de direction notamment).By means of the present invention, it is then possible to simply manage not only the opening and closing of one's vehicle at a distance beyond the range of direct wireless links (about a hundred meters) but also the starting of the vehicle's engine, and the unlocking of all the theft protection devices (locking of the steering column in particular).

La présente invention est très simple d'utilisation puisque le simple appairage du badge avec l'ordiphone permet une identification et une validation du serveur qui autorise ainsi l'échange de données et l'interaction à distance et hors de portée des dispositifs traditionnels. La solution présente également une sécurité élevée puisqu'il est nécessaire que le badge soit plaqué contre l'ordiphone pour l'identification.The present invention is very easy to use since the simple pairing of the badge with the smartphone allows identification and validation of the server, which thus authorizes the exchange of data and remote interaction beyond the reach of traditional devices. The solution also has high security since it is necessary for the badge to be pressed against the smartphone for identification.

Il est envisageable de proposer plusieurs badges 2 portant les informations VIN et le protocole NFC, avec la possibilité de personnaliser chaque badge, voire en restreignant l'accès à certaines fonctions (démarrage du véhicule notamment, mais également limitation de la vitesse maximale, par exemple).It is conceivable to offer several badges 2 bearing the VIN information and the NFC protocol, with the possibility of personalizing each badge, or even restricting access to certain functions (starting the vehicle in particular, but also limiting the maximum speed, for example ).
