Description

L'invention concerne la réalisation à distance de diagnostics de véhicules, éventuellement de type automobile.The invention relates to the remote performance of vehicle diagnostics, possibly of the automotive type.

De nombreux véhicules comportent des équipements électroniques communicants (comme par exemple des calculateurs) qui sont couplés à un équipement de supervision (parfois appelé « boîtier de servitude intelligent » (ou BSI)), lui-même couplé à un module de communication par voie d'ondes. Ce dernier est agencé de manière à servir d'interface de communication entre un outil de diagnostic, couplé à un réseau de communication, et des équipements électroniques communicants de son véhicule, afin que des télédiagnostics de ces derniers puissent être réalisés par un technicien contrôlant l'outil de diagnostic.Many vehicles include communicating electronic equipment (such as computers, for example) which are coupled to supervision equipment (sometimes called an "intelligent service box" (or BSI)), itself coupled to a communication module by means of 'waves. The latter is arranged so as to serve as a communication interface between a diagnostic tool, coupled to a communication network, and communicating electronic equipment in its vehicle, so that remote diagnostics of the latter can be carried out by a technician checking the vehicle. diagnostic tool.

Ces télédiagnostics peuvent être destinés à déterminer à distance l'origine d'une panne ou d'un dysfonctionnement au sein d'un véhicule, à la demande du conducteur, puis à fournir des conseils lorsqu'une intervention du seul conducteur est possible, ou bien si une révision ou une opération de maintenance du véhicule doit être proposée au conducteur, éventuellement accompagnée de propositions de dates d'intervention.These remote diagnostics can be intended to determine remotely the origin of a breakdown or malfunction within a vehicle, at the driver's request, then to provide advice when intervention by the driver alone is possible, or whether an overhaul or maintenance operation of the vehicle must be offered to the driver, possibly accompanied by proposals for intervention dates.

Pour éviter que n'importe quel diagnostic puisse être réalisé à distance sur un équipement électronique communicant, il a été proposé un mécanisme de télédiagnostic sécurisé. Ce dernier consiste à adjoindre à la requête de diagnostic une valeur de paramètre de téléservice, puis à vérifier auprès de l'équipement électronique communicant à diagnostiquer si il reconnaît cette valeur et donc si il supporte le télédiagnostic. Dans l'affirmative, on vérifie dans une liste, associée à l'équipement électronique communicant à diagnostiquer, si la requête de diagnostic reçue en fait partie, et dans l'affirmative, on transmet cette requête de diagnostic à cet équipement électronique communicant afin qu'il fournisse une réponse destinée à l'outil de diagnostic.To prevent any diagnosis from being carried out remotely on communicating electronic equipment, a secure remote diagnosis mechanism has been proposed. The latter consists of adding a teleservice parameter value to the diagnostic request, then checking with the communicating electronic equipment to be diagnosed whether it recognizes this value and therefore whether it supports remote diagnosis. If the answer is yes, it is checked in a list associated with the communicating electronic equipment to be diagnosed whether the diagnostic request received is part of it, and if so, this diagnostic request is transmitted to this communicating electronic equipment so that 'he provides an answer intended for the diagnostic tool.

Lorsque l'équipement électronique communicant à diagnostiquer ne supporte pas le télédiagnostic, par exemple du fait qu'il est ancien, ou lorsque la requête de diagnostic reçue ne fait pas partie de la liste de diagnostics autorisés de l'équipement électronique communicant à diagnostiquer, un message signalant qu'une condition n'est pas satisfaite est transmis à l'outil de diagnostic et donc la requête de diagnostic n'est pas transmise à cet équipement électronique communicant. Par conséquent, il est impossible de réaliser un télédiagnostic d'un équipement électronique communicant qui ne supporte pas un tel télédiagnostic, même si ce dernier peut faire l'objet d'un diagnostic au moyen d'un outil de diagnostic qui est couplé localement à l'équipement de supervision (BSI) de son véhicule.When the communicating electronic equipment to be diagnosed does not support remote diagnosis, for example because it is old, or when the diagnostic request received is not part of the list of authorized diagnoses of the communicating electronic equipment to be diagnosed, a message indicating that a condition is not satisfied is transmitted to the diagnostic tool and therefore the diagnostic request is not transmitted to this communicating electronic equipment item. Consequently, it is impossible to carry out a remote diagnosis of a communicating electronic equipment which does not support such a remote diagnosis, even if the latter can be the subject of a diagnosis by means of a diagnostic tool which is locally coupled to the supervision equipment (BSI) of his vehicle.

Il en résulte que dès qu'un véhicule comprend au moins un équipement électronique communicant qui ne supporte pas un télédiagnostic, certains diagnostics ne peuvent pas être réalisés, ce qui peut s'avérer dangereux. Cela résulte en effet du fait que la réalisation de certains diagnostics nécessite la réalisation préalable d'autres diagnostics. A titre d'exemple illustratif, avant de réaliser un diagnostic de fonctionnement des injecteurs d'un moteur thermique, il faut préalablement savoir si il n'y a pas une fuite de carburant.As a result, as soon as a vehicle includes at least one communicating electronic device which does not support remote diagnosis, certain diagnoses cannot be carried out, which can prove to be dangerous. This results in fact from the fact that the performance of certain diagnoses requires the prior performance of other diagnoses. By way of illustrative example, before carrying out a diagnosis of the operation of the injectors of a heat engine, it is first necessary to know whether there is not a fuel leak.

Le document FR 2 998 237 A1 décrit un procédé qui permet d'améliorer la sécurité d'un diagnostic à distance en intégrant, d'une part, des étapes d'ouverture et de fermeture d'une session dédiée au télédiagnostic à partir de l'embarqué et, d'autre part, en mettant en oeuvre une étape de vérification pour contrôler qu'une requête est autorisée à être exécutée au cours d'une session de télédiagnostic.The document FR 2 998 237 A1 describes a method which makes it possible to improve the security of a remote diagnosis by integrating, on the one hand, the steps of opening and closing a session dedicated to remote diagnosis from the on-board vehicle and, on the other hand part, by implementing a verification step to check that a request is authorized to be executed during a remote diagnosis session.

L'invention a donc notamment pour but d'améliorer la situation.The aim of the invention is therefore in particular to improve the situation.

Elle propose notamment à cet effet un procédé selon la revendication 1 destiné à permettre la réalisation à distance de diagnostics de véhicules comprenant chacun un module de communication propre à communiquer (par voie d'ondes) avec un outil de diagnostic distant et couplé à des équipements électroniques communicants embarqués.For this purpose, it proposes in particular a method according to claim 1 intended to allow remote carrying out of vehicle diagnostics each comprising a communication module suitable for communicating (by means of waves) with a remote diagnostic tool and coupled to equipment. electronic on-board communicators.

Ce procédé se caractérise par le fait qu'il comprend :

  • une première étape dans laquelle l'outil de diagnostic génère une requête de télédiagnostic associée à une valeur d'un paramètre de télédiagnostic à destination d'un équipement électronique communicant d'un véhicule,
  • une deuxième étape dans laquelle on compare cette valeur à une valeur prédéfinie, et en cas d'identité entre ces dernières on transmet une demande de session de télédiagnostic à l'équipement électronique communicant destinataire,
  • une troisième étape dans laquelle ce dernier génère une réponse à la demande, puis si cette réponse est une acceptation de la session de télédiagnostic ou un refus prédéfini de la session de télédiagnostic, on transmet la requête de télédiagnostic à l'équipement électronique communicant, et
  • une quatrième étape dans laquelle on transmet à l'outil de diagnostic un message généré par l'équipement électronique communicant en réponse à
    la requête de télédiagnostic, et en ce qu'à la troisième étape, si cette réponse n'est ni une acceptation de la session de télédiagnostic ni un refus prédéfini de cette session de télédiagnostic, alors on transmet à l'outil de diagnostic un message de réponse signalant qu'une condition n'est pas satisfaite, la requête de télédiagnostic n'étant pas transmise à l'équipement électronique communicant, un refus prédéfini étant un refus de participer à la session de télédiagnostic requise par l'outil de diagnostic, et présentant une valeur prédéfinie qui est une valeur normative en réponse à une demande non prédéfinie.
This process is characterized by the fact that it comprises:
  • a first step in which the diagnostic tool generates a remote diagnostic request associated with a value of a remote diagnostic parameter intended for communicating electronic equipment in a vehicle,
  • a second step in which this value is compared with a predefined value, and in the event of identity between the latter, a request for a remote diagnosis session is sent to the electronic equipment communicating recipient,
  • a third step in which the latter generates a response to the request, then if this response is an acceptance of the remote diagnostic session or a predefined refusal of the remote diagnostic session, the remote diagnostic request is transmitted to the communicating electronic equipment, and
  • a fourth step in which a message generated by the communicating electronic equipment is transmitted to the diagnostic tool in response to
    the remote diagnosis request, and in that in the third step, if this response is neither an acceptance of the remote diagnosis session nor a predefined refusal of this remote diagnosis session, then a message is sent to the diagnostic tool a response indicating that a condition is not satisfied, the remote diagnosis request not being transmitted to the communicating electronic equipment, a predefined refusal being a refusal to participate in the remote diagnosis session required by the diagnostic tool, and having a predefined value which is a normative value in response to a non-predefined request.

Ainsi, de nombreux équipements électroniques communicants anciens, c'est-à-dire n'ayant pas été agencés pour reconnaître une demande de session de télédiagnostic, peuvent désormais faire l'objet d'un télédiagnostic sans que cela ne nécessite leur modification.Thus, many old communicating electronic devices, that is to say that have not been designed to recognize a request for a remote diagnosis session, can now be the subject of a remote diagnosis without requiring their modification.

D'autres caractéristiques et avantages de l'invention apparaîtront à l'examen de la description détaillée ci-après, et des dessins annexés, sur lesquels :

  • la figure 2 illustre schématiquement un exemple d'algorithme mettant en œuvre un exemple de réalisation d'un procédé de réalisation de télédiagnostics selon l'invention.
Other characteristics and advantages of the invention will become apparent on examination of the detailed description below, and of the appended drawings, in which:
  • the figure 1 schematically and functionally illustrates an installation communication to which is coupled an exemplary embodiment of a system for producing remote diagnostics of vehicles according to the invention, and
  • the figure 2 schematically illustrates an example of an algorithm implementing an exemplary embodiment of a method for performing remote diagnostics according to the invention.

L'invention a notamment pour but de proposer un procédé de réalisation de télédiagnostics, et un système de réalisation de télédiagnostics SD associé, destinés à permettre la réalisation de télédiagnostics de véhicules V comprenant des équipements électroniques communicants EEj et un module de communication MC pouvant communiquer par voie d'ondes avec un réseau de communication RC.The object of the invention is in particular to propose a method for performing remote diagnostics, and a system for performing remote diagnostics. SD associated, intended to allow the realization of remote diagnostics of vehicles V comprising communicating electronic equipment EEj and a communication module MC able to communicate by means of waves with an RC communication network.

Dans ce qui suit, on considère, à titre d'exemple non limitatif, que les véhicules V qui peuvent faire l'objet de télédiagnostics sont de type automobile. Il s'agit par exemple de voitures. Mais l'invention n'est pas limitée à ce type de véhicule. Elle concerne en effet tout type de véhicule terrestre, maritime (ou fluvial) ou aérien, dès lors qu'il comprend des équipements électroniques communicants pouvant faire l'objet de diagnostic(s) et couplés à un module de communication pouvant communiquer par voie d'ondes avec un réseau de communication.In what follows, it is considered, by way of nonlimiting example, that the vehicles V which can be the subject of remote diagnostics are of the automobile type. These are, for example, cars. But the invention is not limited to this type of vehicle. It relates in fact to any type of land, sea (or river) or air vehicle, since it includes communicating electronic equipment that can be the subject of diagnosis (s) and coupled to a communication module that can communicate by means of 'waves with a communication network.

On a schématiquement représenté sur la figure 1 un exemple d'installation de communication à laquelle est couplé un exemple de réalisation d'un système SD de télédiagnostics de véhicules V.We have schematically represented on the figure 1 an example of a communication installation to which is coupled an exemplary embodiment of an SD vehicle remote diagnosis system V.

L'installation de communication comprend notamment un réseau de communication RC comportant, d'une part, une infrastructure de communication non filaire à laquelle peuvent se connecter des modules de communication MC implantés dans des véhicules V, et, d'autre part, une infrastructure de communication filaire à laquelle peuvent se connecter des équipements de communication filaire, comme par exemple un serveur SC et un outil de diagnostic OD. On notera que les modules de communication non filaire MC et équipements de communication filaire SC et OD pourraient être connectés à différents réseaux de communication interconnectés les uns aux autres, de préférence via l'Internet.The communication installation comprises in particular an RC communication network comprising, on the one hand, a wireless communication infrastructure to which communication modules MC installed in vehicles V can be connected, and, on the other hand, an infrastructure wired communication device to which wired communication equipment can be connected, such as for example an SC server and an OD diagnostic tool. It will be noted that the wireless communication modules MC and wired communication equipment SC and OD could be connected to different communication networks interconnected with each other, preferably via the Internet.

Chaque véhicule V pouvant faire l'objet de diagnostics comprend au moins des équipements électroniques communicants EEj et un module de communication MC couplés entre eux.Each vehicle V that can be the subject of diagnostics comprises at least communicating electronic equipment EEj and a communication module MC coupled together.

Par exemple, et comme illustré non limitativement, les équipements électroniques communicants EEj sont connectés à au moins un réseau de communication embarqué RCE, éventuellement de type multiplexé.For example, and as illustrated without limitation, the communicating electronic equipment items EEj are connected to at least one on-board communication network RCE, possibly of the multiplexed type.

On entend ici par « équipement électronique communicant » un équipement capable de recevoir et de traiter des trames de données numériques circulant dans le bus d'un réseau de communication embarqué RCE auquel il est connecté, ainsi que de fournir à ce dernier (RCE) des trames de données destinées à au moins un autre équipement électronique communicant. Il pourra, par exemple, s'agir d'un calculateur, d'un capteur ou d'un actionneur.The term “communicating electronic equipment” is understood here to mean equipment capable of receiving and processing data frames. digital devices circulating in the bus of an on-board communication network RCE to which it is connected, as well as supplying the latter (RCE) with data frames intended for at least one other communicating electronic device. It could, for example, be a computer, a sensor or an actuator.

On notera que dans l'exemple illustré non limitativement sur la figure 1, le véhicule V comprend quatre équipements électroniques communicants EEj (j = 1 à 4). Mais le nombre d'équipements électroniques communicants EEj peut prendre n'importe quelle valeur supérieure ou égale à un (1).It will be noted that in the example illustrated without limitation on figure 1 , the vehicle V comprises four communicating electronic devices EEj (j = 1 to 4). But the number of communicating electronic devices EEj can take any value greater than or equal to one (1).

On notera également que dans l'exemple illustré non limitativement sur la figure 1, le véhicule V comprend également un équipement de supervision ES connecté au réseau de communication embarqué RCE et au module de communication MC. Cet équipement de supervision ES est un équipement électronique communicant qui est notamment chargé d'assurer l'interfaçage entre le module de communication MC et les autres équipements électroniques communicants EEj et de contrôler des fonctionnalités de diagnostic. Il s'agit par exemple de ce que l'homme de l'art appelle parfois un « boîtier de servitude intelligent » (ou BSI)).It will also be noted that in the example illustrated without limitation on figure 1 , the vehicle V also includes supervision equipment ES connected to the on-board communication network RCE and to the communication module MC. This supervision device ES is a communicating electronic device which is in particular responsible for ensuring the interfacing between the communication module MC and the other communicating electronic devices EEj and for controlling diagnostic functions. This is, for example, what a person skilled in the art sometimes calls an "intelligent service box" (or BSI)).

Par ailleurs, chaque véhicule V est associé à un identifiant de véhicule. Ce dernier peut, par exemple, être celui qui est appelé en anglais « Vehicle Identification Number » (ou VIN).Furthermore, each vehicle V is associated with a vehicle identifier. The latter can, for example, be the one which is called in English “Vehicle Identification Number” (or VIN).

Comme illustré non limitativement sur l'unique figure, un système de réalisation de télédiagnostics SD, selon l'invention, comprend au moins des moyens de traitement MT et un outil de diagnostic OD.As illustrated without limitation in the single figure, a system for performing SD remote diagnostics, according to the invention, comprises at least MT processing means and an OD diagnostic tool.

L'outil de diagnostic OD est agencé pour réaliser à distance, éventuellement à la demande du module de communication MC d'un véhicule V ou d'un équipement de communication sans fil utilisé par un passager du véhicule V, un télédiagnostic de ce dernier (V), fonction de son identifiant de véhicule.The diagnostic tool OD is designed to carry out remotely, possibly at the request of the communication module MC of a vehicle V or of a wireless communication device used by a passenger of the vehicle V, a remote diagnosis of the latter ( V), depending on its vehicle identifier.

Cet outil de diagnostic OD est, par exemple, un ordinateur fixe ou portable connecté au réseau de communication RC et utilisé par un téléopérateur ou un réparateur sachant contrôler un télédiagnostic et faire des propositions une fois ce dernier terminé. Par ailleurs, cet outil de diagnostic OD peut, par exemple, appartenir à un service après-ventes d'un fabriquant de véhicules (ici un constructeur automobile).This OD diagnostic tool is, for example, a fixed or laptop computer connected to the RC communication network and used by a teleoperator or a repairman who knows how to control a remote diagnosis and make proposals once the latter has been completed. Moreover, this diagnostic tool OD can, for example, belong to an after-sales service of a vehicle manufacturer (here an automobile manufacturer).

L'outil de diagnostic OD comprend notamment des modules logiciels (ou « software ») constituant ensemble un programme similaire à celui qui est implanté dans un outil de diagnostic utilisé par les techniciens d'un garage (ou d'une concession), comme par exemple celui qui est appelé DiagBox® et qui sert à diagnostiquer les problèmes dans les véhicules des marques Peugeot et Citroën.The OD diagnostic tool includes in particular software modules (or "software") together constituting a program similar to that installed in a diagnostic tool used by technicians in a garage (or a dealership), such as example the one called DiagBox® and which is used to diagnose problems in vehicles of the Peugeot and Citroën brands.

L'outil de diagnostic OD peut comporter des premiers moyens de stockage MS1 dans lesquels se trouvent stockés tous les diagnostics qui peuvent être réalisés à distance pour certains au moins des modèles de véhicule d'au moins une marque, lesquels sont identifiés par leur identifiant de véhicule. Ces premiers moyens de stockage MS1 peuvent se présenter sous n'importe quelle forme connue de l'homme de l'art, et notamment sous la forme d'une mémoire ou d'une banque de données.The diagnostic tool OD can include first storage means MS1 in which are stored all the diagnostics which can be carried out remotely for at least some of the vehicle models of at least one make, which are identified by their vehicle identifier. vehicle. These first storage means MS1 can be in any form known to those skilled in the art, and in particular in the form of a memory or a database.

Chaque module de communication MC est notamment propre à dialoguer avec un outil de diagnostic OD pour demander la réalisation d'un télédiagnostic de son véhicule V et pour lui transmettre l'identifiant de véhicule de ce véhicule V. Il comprend des circuits électroniques (ou « hardware ») et des modules logiciels (ou « software »). Par ailleurs, il sert également de passerelle de communication (ou « gateway ») entre l'outil de diagnostic OD et les équipements électroniques communicants EEj de son véhicule V, via (ici) leur équipement de supervision ES, pour qu'ils échangent des requêtes de diagnostic et des messages de réponse à ces requêtes de diagnostic. Une requête de télédiagnostic est un message comportant notamment un identifiant de diagnostic à réaliser et un identifiant d'équipement électronique communicant EEj à diagnostiquer.Each communication module MC is in particular suitable for dialoguing with a diagnostic tool OD in order to request a remote diagnosis of its vehicle V and to transmit to it the vehicle identifier of this vehicle V. It comprises electronic circuits (or " hardware ”) and software modules (or“ software ”). In addition, it also serves as a communication gateway (or “gateway”) between the diagnostic tool OD and the communicating electronic equipment EEj of its vehicle V, via (here) their supervision equipment ES, so that they can exchange data. diagnostic queries and response messages to these diagnostic queries. A remote diagnosis request is a message comprising in particular a diagnostic identifier to be performed and an identifier of communicating electronic equipment EEj to be diagnosed.

On comprendra que cet échange de requête et de messages de réponse est destiné à permettre à l'outil de diagnostic OD qui communique temporairement avec un véhicule V, via son module de communication MC, de réaliser un diagnostic à distance (ou télédiagnostic), puis de transmettre un résultat de diagnostic à ce véhicule V.It will be understood that this exchange of request and response messages is intended to allow the diagnostic tool OD which communicates temporarily with a vehicle V, via its communication module MC, to carry out a remote diagnosis (or remote diagnosis), then to transmit a diagnostic result to this V.

Pour que les requêtes de diagnostic puissent être utilisées par au moins un réseau de communication embarqué RCE d'un véhicule V, il faut qu'elles se présentent sous la forme de trames conformes au protocole de communication qui est utilisé dans leurs bus (par exemple le protocole CAN), et pour que ces trames (CAN) puissent parvenir jusqu'au au niveau de l'équipement de supervision ES via le réseau IP, il faut qu'elles soient en outre encapsulées en TCP/IP (« Transport Control Protocol / Internet Protocol »). De préférence, le module de communication MC est chargé de gérer tous les aspects de l'encapsulation. Dans ce cas, il (MC) est chargé de désencapsuler les trames encapsulées en TCP/IP pour récupérer les seules trames CAN afin de les transmettre à leur(s) destinataire(s). De même, il (MC) est chargé d'encapsuler les trames CAN comprenant les messages de réponse en TCP/IP, pour qu'elles puissent être transmises à l'outil de diagnostic OD.So that diagnostic queries can be used by au minus an on-board communication network RCE of a vehicle V, they must be in the form of frames conforming to the communication protocol which is used in their buses (for example the CAN protocol), and so that these frames ( CAN) can reach the level of the supervision equipment ES via the IP network, they must also be encapsulated in TCP / IP (“Transport Control Protocol / Internet Protocol”). Preferably, the communication module MC is responsible for managing all aspects of the encapsulation. In this case, it (MC) is responsible for de-encapsulating the frames encapsulated in TCP / IP to recover the only CAN frames in order to transmit them to their recipient (s). Likewise, it (MC) is responsible for encapsulating the CAN frames comprising the response messages in TCP / IP, so that they can be transmitted to the OD diagnostic tool.

Le module de communication MC peut, par exemple, être de type 3G ou 4G de manière à pouvoir être accessible directement par son adresse IP (privée et fournie par contrat par un opérateur, ou publique et re-routée temporairement par un opérateur sur une adresse dans le cadre d'une session de communication et donc considérée comme privée uniquement pendant la durée de cette session de communication).The MC communication module can, for example, be of the 3G or 4G type so that it can be accessed directly by its IP address (private and provided by contract by an operator, or public and temporarily re-routed by an operator to an address within the framework of a communication session and therefore considered as private only for the duration of this communication session).

Lorsque c'est le véhicule V qui sollicite un télédiagnostic, éventuellement à la demande du conducteur, son module de communication MC initie une communication de données (et éventuellement de voix) avec l'outil de diagnostic OD, éventuellement via un serveur de communication SC. L'éventuelle communication de voix (ou téléphonique) est destinée à permettre au téléopérateur ou réparateur qui utilise l'outil de diagnostic OD de dialoguer par téléphone avec un passager du véhicule V. La communication de données (ou « data ») est établie, par exemple sous IP (« Internet Protocol »). Le module de communication MC peut se connecter directement à l'éventuel serveur de communication SC via l'Internet du fait qu'il connait son adresse IP.When it is the vehicle V which requests a remote diagnosis, possibly at the request of the driver, its communication module MC initiates data communication (and possibly voice) with the diagnostic tool OD, possibly via a communication server SC . Any voice (or telephone) communication is intended to allow the teleoperator or repairer who uses the OD diagnostic tool to communicate by telephone with a passenger in vehicle V. Data communication (or "data") is established, for example under IP (“Internet Protocol”). The communication module MC can connect directly to the possible communication server SC via the Internet because it knows its IP address.

On notera que l'éventuel serveur de communication SC peut appartenir au service après-ventes du fabriquant de véhicules (ici un constructeur automobile). Il peut également faire partie du système de réalisation de télédiagnostics SD.It will be noted that the possible communication server SC can belong to the after-sales service of the vehicle manufacturer (here an automobile manufacturer). It can also be part of the SD remote diagnostics system.

Comme indiqué plus haut, l'invention propose un procédé de réalisation de télédiagnostics qui peut être mis en œuvre au moyen d'un système de réalisation de télédiagnostics SD. Un tel procédé comprend au moins quatre étapes.As indicated above, the invention provides a method for performing remote diagnostics which can be implemented by means of an SD remote diagnostics system. Such a method comprises at least four steps.

Une première étape, du procédé selon l'invention, est initiée lorsqu'un télédiagnostic a été requis ou décidé pour un véhicule V.A first step, of the method according to the invention, is initiated when a remote diagnosis has been required or decided for a V vehicle.

Dans cette première étape, l'outil de diagnostic OD génère une requête de télédiagnostic associée à une valeur vpd (ou « flag ») d'un paramètre de télédiagnostic à destination d'un équipement électronique communicant EEj d'un véhicule V.In this first step, the diagnostic tool OD generates a remote diagnosis request associated with a value v pd (or “flag”) of a remote diagnosis parameter intended for communicating electronic equipment EEj of a vehicle V.

Dans une deuxième étape, du procédé selon l'invention, on compare la valeur vpd à une valeur prédéfinie v1, et en cas d'identité entre ces dernières (vpd et v1) on transmet une demande de session de télédiagnostic à l'équipement électronique communicant EEj qui est le destinataire de la requête de télédiagnostic. Cette transmission se fait via l'éventuel serveur de communication SC, le réseau de communication RC, le module de communication MC et les éventuels équipements de supervision ES et réseau de communication embarqué RCE.In a second step, of the method according to the invention, the value v pd is compared with a predefined value v1, and in the event of identity between the latter (v pd and v1), a request for a remote diagnosis session is transmitted to the communicating electronic equipment EEj which is the recipient of the remote diagnosis request. This transmission is done via the possible communication server SC, the communication network RC, the communication module MC and any supervision equipment ES and on-board communication network RCE.

La valeur prédéfinie v1 peut, par exemple, être codée sur au moins un bit. A titre d'exemple, elle peut être égale à un (1). Mais elle pourrait être codée différemment (par exemple sur plusieurs bits).The predefined value v1 can, for example, be coded on at least one bit. For example, it can be equal to one (1). But it could be coded differently (for example on several bits).

La comparaison de valeurs (vpd et v1) est destinée à sécuriser la phase de télédiagnostics. En effet, si les valeurs vpd et v1 ne sont pas identiques on (les moyens de traitement MT du système de réalisation de télédiagnostics SD) adresse(nt) à l'outil de diagnostic OD un message signalant qu'une condition n'est pas satisfaite, et donc la requête de télédiagnostic n'est pas transmise à l'équipement électronique communicant EEj qui en est le destinataire.The comparison of values (v pd and v1) is intended to secure the remote diagnosis phase. Indeed, if the values v pd and v1 are not identical, on (the MT processing means of the SD remote diagnostics system) sends (s) to the diagnostic tool OD a message indicating that a condition is not satisfied, and therefore the remote diagnosis request is not transmitted to the communicating electronic equipment EEj which is the recipient.

Cette comparaison de valeurs (vpd et v1) peut être réalisée en au moins deux endroits différents.This comparison of values (v pd and v1) can be carried out in at least two different places.

Ainsi, et comme illustré non limitativement sur la figure 1, elle peut être réalisée dans le module de communication MC du véhicule V qui comprend l'équipement électronique communicant EEj qui est le destinataire de la requête de télédiagnostic. Dans ce cas, le module de communication MC doit être équipé des moyens de traitement MT du système de réalisation de télédiagnostics SD, du fait qu'ils sont notamment chargés de réaliser les comparaisons de valeurs (vpd et v1). A cet effet, les moyens de traitement MT peuvent être agencés sous la forme de circuits électroniques et/ou de modules logiciels.Thus, and as illustrated without limitation on figure 1 , it can be carried out in the communication module MC of the vehicle V which comprises the communicating electronic equipment EEj which is the recipient of the remote diagnosis request. In this case, the communication module MC must be equipped with the processing means MT of the remote diagnostic performance system SD, owing to the fact that they are in particular responsible for carrying out the comparisons of values (v pd and v1). For this purpose, the processing means MT can be arranged in the form of electronic circuits and / or software modules.

Dans une variante de réalisation non illustrée, la comparaison de valeurs (vpd et v1) peut être réalisée dans le serveur de communication SC qui assure l'interface de communication entre l'outil de diagnostic OD et le module de communication MC du véhicule V diagnostiqué. Dans ce cas, le serveur de communication SC doit être équipé des moyens de traitement MT précités du système de réalisation de télédiagnostics SD. Cette variante évite d'accroitre le nombre de tâches que doit assurer chaque module de communication MC, mais elle augmente notablement les temps d'obtention des informations, voire peut induire l'arrêt logiciel d'une phase de télédiagnostics lorsque le serveur de communication SC est surchargé et/ou le réseau de communication RC encombré.In an alternative embodiment not illustrated, the comparison of values (v pd and v1) can be carried out in the communication server SC which provides the communication interface between the diagnostic tool OD and the communication module MC of the vehicle V diagnostic. In this case, the communication server SC must be equipped with the aforementioned MT processing means of the SD remote diagnostics system. This variant avoids increasing the number of tasks to be performed by each MC communication module, but it significantly increases the times for obtaining information, and can even lead to the software stopping of a remote diagnosis phase when the communication server SC is overloaded and / or the RC communication network is congested.

Afin de sécuriser encore plus la phase de télédiagnostics, dans la deuxième étape, en cas d'identité entre la valeur vpd et la valeur prédéfinie v1, on peut commencer par vérifier si la requête de télédiagnostic est autorisée pour l'équipement électronique communicant EEj. Cette vérification est réalisée par les moyens de traitement MT auprès de seconds moyens de stockage MS2 qui stockent des identifiants de diagnostics en correspondance d'identifiants d'équipements électroniques communicants EEj.In order to make the remote diagnostics phase even more secure, in the second step, in the event of an identity between the value v pd and the predefined value v1, it is possible to start by checking whether the remote diagnostics request is authorized for the communicating electronic equipment EEj . This verification is carried out by the processing means MT with second storage means MS2 which store diagnostic identifiers in correspondence with identifiers of communicating electronic equipment EEj.

Comme illustré non limitativement sur la figure 1, les seconds moyens de stockage MS2 peuvent être implantés dans l'équipement (ici le module de communication MC) qui comprend les moyens de traitement MT. Mais cela n'est pas obligatoire. En effet, ils pourraient être déportés, par exemple dans l'équipement de supervision ES ou dans le serveur de communication SC. Dans ce dernier cas (totalement déporté), les seconds moyens de stockage MS2 doivent stocker des identifiants de diagnostics en correspondance d'identifiants d'équipements électroniques communicants EEj et d'identifiants de véhicules.As illustrated without limitation on figure 1 , the second storage means MS2 can be installed in the equipment (here the communication module MC) which comprises the processing means MT. But it is not compulsory. Indeed, they could be deported, for example in the supervision equipment ES or in the communication server SC. In the latter case (totally remote), the second storage means MS2 must store diagnostic identifiers corresponding to identifiers of communicating electronic equipment EEj and vehicle identifiers.

Ces seconds moyens de stockage MS2 peuvent se présenter sous n'importe quelle forme connue de l'homme de l'art, et notamment sous la forme d'une mémoire ou d'une banque de données.These second storage means MS2 can be in any form known to those skilled in the art, and in particular in the form of a memory or a database.

Une fois la vérification terminée, on transmet la demande de session de télédiagnostic à l'équipement électronique communicant EEj si la requête de télédiagnostic est autorisée pour ce dernier (EEj).Once the verification is complete, the request for a remote diagnosis session is transmitted to the communicating electronic equipment item EEj if the remote diagnosis request is authorized for the latter (EEj).

Dans une troisième étape, du procédé selon l'invention, l'équipement électronique communicant EEj diagnostiqué génère une réponse à la demande de session de télédiagnostic qu'il a reçue en fin de deuxième étape si les valeurs vpd et v1 étaient identiques. Puis, si cette réponse est une acceptation de la session de télédiagnostic ou un refus prédéfini de cette session de télédiagnostic, on transmet la requête de télédiagnostic à l'équipement électronique communicant EEj diagnostiqué.In a third step, of the method according to the invention, the diagnosed communicating electronic equipment EEj generates a response to the remote diagnostic session request that it received at the end of the second step if the values v pd and v1 were identical. Then, if this response is an acceptance of the remote diagnostic session or a predefined refusal of this remote diagnostic session, the remote diagnostic request is transmitted to the communicating electronic equipment EEj diagnosed.

On entend ici par « acceptation de la session de télédiagnostic » une acceptation de participer à la session de télédiagnostic requise par l'outil de diagnostic OD. Une telle acceptation est automatiquement décidée par un équipement électronique communicant EEj de fabrication récente, et donc qui a été agencé de manière à reconnaître et accepter une demande de session de télédiagnostic afin de pouvoir faire l'objet de diagnostics à distance.By “acceptance of the remote diagnosis session” is meant here an acceptance to participate in the remote diagnosis session required by the diagnostic tool OD. Such acceptance is automatically decided by a communicating electronic equipment EEj of recent manufacture, and therefore which has been arranged so as to recognize and accept a request for a remote diagnosis session in order to be able to be the subject of remote diagnostics.

On entend par « refus prédéfini » un refus de participer à la session de télédiagnostic requise par l'outil de diagnostic OD, et présentant une « valeur » prédéfinie, comme par exemple « NACK 12 », qui est une valeur normative en réponse à une demande non prédéfinie. Un tel refus est automatiquement décidé par un équipement électronique communicant EEj de fabrication ancienne, et donc qui ne peut pas faire l'objet de diagnostics à distance du fait qu'il n'a pas été agencé pour reconnaître une demande de session de télédiagnostic.The term “predefined refusal” is understood to mean a refusal to participate in the remote diagnostic session required by the diagnostic tool OD, and having a predefined “value”, such as for example “NACK 12”, which is a normative value in response to a non-predefined request. Such a refusal is automatically decided by a communicating electronic equipment EEj of old manufacture, and therefore which cannot be the subject of remote diagnostics because it has not been arranged to recognize a request for a remote diagnostic session.

L'analyse de la réponse à la demande de session de télédiagnostic, générée par l'équipement électronique communicant EEj diagnostiqué, est réalisée par les moyens de traitement MT. Par conséquent elle peut être réalisée soit dans le module de communication MC (comme illustré non limitativement sur la figure 1), soit dans le serveur de communication SC.The analysis of the response to the remote diagnostic session request, generated by the diagnosed communicating electronic equipment EEj, is carried out by the processing means MT. Consequently, it can be carried out either in the MC communication module (as illustrated without limitation on the figure 1 ), or in the communication server SC.

Dans le cas d'une réalisation dans le module de communication MC, dans la troisième étape les moyens de traitement MT analysent la réponse générée par l'équipement électronique communicant EEj. Puis, si cette réponse est une acceptation ou un refus prédéfini de la session de télédiagnostic, ils déclenchent la transmission par le module de communication MC de la requête de télédiagnostic reçue dans la première étape à cet équipement électronique communicant EEj.In the case of an implementation in the MC communication module, in the third step, the processing means MT analyze the response generated by the communicating electronic equipment EEj. Then, if this response is a predefined acceptance or rejection of the remote diagnosis session, they trigger the transmission by the communication module MC of the remote diagnosis request received in the first step to this communicating electronic equipment item EEj.

Dans le cas d'une réalisation dans le serveur de communication SC, dans la troisième étape les moyens de traitement MT analysent la réponse générée par l'équipement électronique communicant EEj. Puis, si cette réponse est une acceptation ou un refus prédéfini de la session de télédiagnostic, ils déclenchent la transmission par le serveur de communication SC de la requête de télédiagnostic reçue dans la première étape à cet équipement électronique communicant EEj, via le réseau de communication RC et le module de communication MC du véhicule V diagnostiqué.In the case of an implementation in the communication server SC, in the third step the processing means MT analyze the response generated by the communicating electronic equipment EEj. Then, if this response is a predefined acceptance or refusal of the remote diagnosis session, they trigger the transmission by the communication server SC of the remote diagnosis request received in the first step to this communicating electronic equipment EEj, via the communication network RC and the MC communication module of the vehicle V diagnosed.

Dans une quatrième étape, du procédé selon l'invention, on transmet à l'outil de diagnostic OD un message qui a été généré par l'équipement électronique communicant EEj diagnostiqué en réponse à la requête de télédiagnostic transmise lors de la troisième étape. Cette transmission est assurée par le module de communication MC, et se fait via le réseau de communication RC et l'éventuel serveur de communication SC.In a fourth step, of the method according to the invention, a message which was generated by the communicating electronic equipment EEj diagnosed in response to the remote diagnosis request transmitted during the third step is transmitted to the diagnostic tool OD. This transmission is provided by the communication module MC, and is done via the communication network RC and the possible communication server SC.

On notera que dans la quatrième étape, lorsque la réponse à la demande de session de télédiagnostic est une acceptation de cette session de télédiagnostic, il est préférable de commencer par adresser à l'équipement électronique communicant EEj, qui est le destinataire de la requête de télédiagnostic, un message de fermeture de session de télédiagnostic, afin qu'il sache que son télédiagnostic est terminé. La transmission de ce message de fermeture de session de télédiagnostic est déclenchée par les moyens de traitement MT. Par conséquent elle peut être réalisée soit dans le module de communication MC (comme illustré non limitativement sur la figure 1), soit dans le serveur de communication SC.It will be noted that in the fourth step, when the response to the request for a remote diagnosis session is an acceptance of this remote diagnosis session, it is preferable to start by sending to the communicating electronic equipment EEj, which is the recipient of the request for remote diagnosis, a message to close the remote diagnosis session, so that he knows that his remote diagnosis is complete. The transmission of this remote diagnostic session closure message is triggered by the processing means MT. Consequently, it can be carried out either in the MC communication module (as illustrated without limitation on the figure 1 ), or in the communication server SC.

Puis, en cas de réception d'un message de confirmation de fermeture de cette session de télédiagnostic, on transmet à l'outil de diagnostic OD le message qui a été généré par l'équipement électronique communicant EEj en réponse à la requête de télédiagnostic, accompagné d'une valeur prédéfinie du paramètre de télédiagnostic. Cette valeur est par exemple la même que celle référencée vpd qui a été transmise lors de la première étape. La transmission de ce message de réponse à la requête de télédiagnostic est déclenchée par les moyens de traitement MT. Par conséquent elle peut être réalisée soit dans le module de communication MC (comme illustré non limitativement sur la figure 1), soit dans le serveur de communication SC.Then, if a message is received to confirm the closure of this remote diagnostic session, the OD diagnostic tool is sent to the message which was generated by the communicating electronic equipment EEj in response to the remote diagnosis request, accompanied by a predefined value of the remote diagnosis parameter. This value is for example the same as that referenced v pd which was transmitted during the first step. The transmission of this response message to the remote diagnosis request is triggered by the processing means MT. Consequently, it can be carried out either in the MC communication module (as illustrated without limitation on the figure 1 ), or in the communication server SC.

On notera également que dans la quatrième étape, lorsque la réponse à la demande de session de télédiagnostic est un refus prédéfini de cette session de télédiagnostic, il n'y a pas de session de télédiagnostic à fermer. Par conséquent, dès que l'on reçoit le message généré par l'équipement électronique communicant EEj en réponse à la requête de télédiagnostic, on peut le transmettre à l'outil de diagnostic OD accompagné d'une valeur prédéfinie du paramètre de télédiagnostic. Cette valeur est par exemple la même que celle référencée vpd qui a été transmise lors de la première étape. La transmission de ce message de réponse à la requête de télédiagnostic est déclenchée par les moyens de traitement MT. Par conséquent elle peut être réalisée soit dans le module de communication MC (comme illustré non limitativement sur la figure 1), soit dans le serveur de communication SC.It will also be noted that in the fourth step, when the response to the request for a remote diagnostic session is a predefined refusal of this remote diagnostic session, there is no remote diagnostic session to close. Consequently, as soon as the message generated by the communicating electronic equipment EEj is received in response to the remote diagnosis request, it can be transmitted to the diagnostic tool OD accompanied by a predefined value of the remote diagnosis parameter. This value is for example the same as that referenced v pd which was transmitted during the first step. The transmission of this response message to the remote diagnosis request is triggered by the processing means MT. Consequently, it can be carried out either in the MC communication module (as illustrated without limitation on the figure 1 ), or in the communication server SC.

On a schématiquement illustré sur la figure 2 un exemple d'algorithme mettant en œuvre un exemple de réalisation d'un procédé de réalisation de télédiagnostics selon l'invention. Cet exemple correspond au cas où les moyens de traitement MT du système de réalisation de télédiagnostics SD sont implantés dans le module de communication MC du véhicule V diagnostiqué.We have schematically illustrated on the figure 2 an example of an algorithm implementing an exemplary embodiment of a method for performing remote diagnostics according to the invention. This example corresponds to the case where the processing means MT of the system for carrying out remote diagnostics SD are installed in the communication module MC of the vehicle V diagnosed.

Dans une sous-étape 10, l'outil de diagnostic OD génère une requête de télédiagnostic associée à une valeur vpd d'un paramètre de télédiagnostic, puis il la transmet à destination d'un équipement électronique communicant EEj choisi du véhicule V.In a sub-step 10, the diagnostic tool OD generates a remote diagnostic request associated with a value v pd of a remote diagnostic parameter, then it transmits it to a communicating electronic device EEj chosen from the vehicle V.

La première étape du procédé selon l'invention correspond à cette sous-étape 10.The first step of the method according to the invention corresponds to this sub-step 10.

Dans une sous-étape 20 on (les moyens de traitement MT) effectue(nt) un test pour comparer la valeur vpd à une valeur prédéfinie v1.In a sub-step 20, (the processing means MT) perform (s) a test to compare the value v pd with a predefined value v1.

Si vpd et v1 ne sont pas identiques, on effectue une sous-étape 30 dans laquelle on (les moyens de traitement MT) transmet(tent) à l'outil de diagnostic OD un message de réponse signalant qu'une condition n'est pas satisfaite, et donc la requête de télédiagnostic n'est pas transmise à l'équipement électronique communicant EEj qui en est le destinataire.If v pd and v1 are not identical, a sub-step 30 is carried out in which one (the processing means MT) transmits (tent) to the diagnostic tool OD a response message indicating that a condition is not not satisfied, and therefore the remote diagnosis request is not transmitted to the communicating electronic equipment EEj which is the recipient.

En revanche, en cas d'identité entre vpd et v1, on (les moyens de traitement MT) effectue(nt) une sous-étape 40 de vérification. Plus précisément, on (les moyens de traitement MT) vérifie(nt) auprès des seconds moyens de stockage MS2 si la requête de télédiagnostic est autorisée pour l'équipement électronique communicant EEj qui en est le destinataire.On the other hand, in the event of identity between v pd and v1, one (the processing means MT) performs (s) a verification sub-step 40. More precisely, one (the processing means MT) checks with the second storage means MS2 whether the remote diagnosis request is authorized for the communicating electronic equipment EEj which is the recipient thereof.

Dans la négative, on (les moyens de traitement MT) effectue(nt) la sous-étape 30, afin de transmettre à l'outil de diagnostic OD un message de réponse signalant qu'une condition n'est pas satisfaite, et donc la requête de télédiagnostic n'est pas transmise à l'équipement électronique communicant EEj qui en est le destinataire.If not, the processing means MT (the processing means MT) perform (s) the sub-step 30, in order to transmit to the diagnostic tool OD a response message indicating that a condition is not satisfied, and therefore the remote diagnosis request is not transmitted to the communicating electronic equipment EEj which is the recipient.

Dans l'affirmative, on effectue une sous-étape 50 dans laquelle les moyens de traitement MT déclenchent la transmission d'une demande de session de télédiagnostic à l'équipement électronique communicant EEj qui est le destinataire de la requête de télédiagnostic.If so, a sub-step 50 is carried out in which the processing means MT trigger the transmission of a request for a remote diagnosis session to the communicating electronic equipment item EEj which is the recipient of the remote diagnosis request.

La deuxième étape, du procédé selon l'invention, correspond aux sous-étapes 20, 40 et 50.The second step, of the method according to the invention, corresponds to sub-steps 20, 40 and 50.

Puis, dans une sous-étape 60 l'équipement électronique communicant EEj diagnostiqué génère et transmet une réponse à la demande de session de télédiagnostic qu'il a reçue.Then, in a sub-step 60, the diagnosed communicating electronic equipment EEj generates and transmits a response to the remote diagnosis session request that it has received.

Ensuite, dans une sous-étape 70 on (les moyens de traitement MT) analyse(nt) la réponse à la demande de session de télédiagnostic transmise par l'équipement électronique communicant EEj.Then, in a sub-step 70, the processing means MT (the means of processing MT) analyze (s) the response to the request for a remote diagnosis session transmitted by the communicating electronic equipment item EEj.

Si cette réponse est ni une acceptation de la session de télédiagnostic ni un refus prédéfini, comme par exemple « NACK 12 », qui est une valeur normative en réponse à une demande non prédéfinie, de cette session de télédiagnostic, on (les moyens de traitement MT) effectue(nt) la sous-étape 30, afin de transmettre à l'outil de diagnostic OD un message de réponse signalant qu'une condition n'est pas satisfaite, et donc la requête de télédiagnostic n'est pas transmise à l'équipement électronique communicant EEj qui en est le destinataire.If this response is neither an acceptance of the session remote diagnosis or a predefined refusal, such as for example "NACK 12", which is a normative value in response to a non-predefined request, of this remote diagnostic session, one (the processing means MT) performs (s) the sub-step 30, in order to transmit to the diagnostic tool OD a response message indicating that a condition is not satisfied, and therefore the remote diagnosis request is not transmitted to the communicating electronic equipment EEj which is the recipient.

En revanche, si cette réponse est une acceptation de la session de télédiagnostic ou un refus prédéfini (comme par exemple « NACK 12 ») de cette session de télédiagnostic, on effectue une sous-étape 80. Dans cette dernière (80), on (les moyens de traitement MT) transmet(tent) la requête de télédiagnostic, reçue dans la sous-étape 10, à l'équipement électronique communicant EEj diagnostiqué. Puis, l'équipement électronique communicant EEj diagnostiqué génère et transmet une réponse à la requête de télédiagnostic qu'il a reçue.On the other hand, if this response is an acceptance of the remote diagnostic session or a predefined refusal (such as “NACK 12”) of this remote diagnostic session, a sub-step 80 is carried out. In the latter (80), ( the processing means MT) transmits (tent) the remote diagnosis request, received in the sub-step 10, to the communicating electronic equipment EEj diagnosed. Then, the diagnosed communicating electronic equipment EEj generates and transmits a response to the remote diagnosis request that it has received.

La troisième étape, du procédé selon l'invention, correspond aux sous-étapes 60 à 80.The third step, of the method according to the invention, corresponds to sub-steps 60 to 80.

Si l'équipement électronique communicant EEj diagnostiqué est ancien, et donc qu'il n'a pas été agencé pour reconnaître une demande de session de télédiagnostic, on effectue ensuite une sous-étape 90. Dans cette dernière (90), on (les moyens de traitement MT) transmet(tent) à l'outil de diagnostic OD le message, qui a été généré par l'équipement électronique communicant EEj diagnostiqué en réponse à la requête de télédiagnostic, accompagné d'une valeur prédéfinie du paramètre de télédiagnostic.If the communicating electronic equipment EEj diagnosed is old, and therefore it has not been arranged to recognize a request for a remote diagnosis session, a sub-step 90 is then carried out. In the latter (90), (the processing means MT) transmits (tent) to the diagnostic tool OD the message, which was generated by the communicating electronic equipment EEj diagnosed in response to the remote diagnosis request, accompanied by a predefined value of the remote diagnosis parameter.

En revanche, si l'équipement électronique communicant EEj diagnostiqué a accepté la session de télédiagnostic lors de la sous-étape 60, on effectue ensuite une sous-étape 100. Dans cette dernière (100), on (les moyens de traitement MT) transmet(tent) à l'équipement électronique communicant EEj, qui est le destinataire de la requête de télédiagnostic, un message de fermeture de session de télédiagnostic, afin qu'il sache que son télédiagnostic est terminé. Puis, en cas de réception d'un message de confirmation de fermeture de cette session de télédiagnostic, on (les moyens de traitement MT) transmet(tent) à l'outil de diagnostic OD le message, qui a été généré par l'équipement électronique communicant EEj diagnostiqué en réponse à la requête de télédiagnostic, accompagné d'une valeur prédéfinie du paramètre de télédiagnostic.On the other hand, if the communicating electronic equipment EEj diagnosed has accepted the telediagnostic session during the sub-step 60, a sub-step 100 is then carried out. In the latter (100), one (the processing means MT) transmits (tent) to the communicating electronic equipment EEj, which is the recipient of the remote diagnosis request, a remote diagnosis session closure message, so that it knows that its remote diagnosis is complete. Then, if a message is received to confirm the closing of this remote diagnostic session, (the MT processing means) transmit (tent) to the diagnostic tool OD the message, which was generated by the equipment. communicating electronic EEj diagnosed in response to the remote diagnosis request, accompanied by a predefined value of the remote diagnosis parameter.

La quatrième étape, du procédé selon l'invention, correspond aux sous-étapes 90 et 100.The fourth step, of the method according to the invention, corresponds to sub-steps 90 and 100.
