Description

La présente invention revendique la priorité de la demande française 0652934 déposée le 12/07/2006 .The present invention claims the priority of the French application 0652934 filed on the 12/07/2006 .

La présente invention concerne un système de contrôle de la qualité de carburant distribué.The present invention relates to a distributed fuel quality control system.

On connaît de la demande de brevet américain n° 2005/222723 un système de contrôle de paramètre lié à un véhicule automobile comprenant un serveur central, relié par un réseau de télécommunication à une flotte de véhicules automobiles. Chaque véhicule automobile de la flotte est muni de moyens de collecte de paramètres liés au véhicule, comportant par exemple un capteur de niveau de carburant, un capteur de pression des pneus ou un dispositif de localisation du véhicule.US Pat. 2005/222723 a parameter control system connected to a motor vehicle comprising a central server, connected by a telecommunications network to a fleet of motor vehicles. Each motor vehicle in the fleet is provided with means for collecting parameters related to the vehicle, for example comprising a fuel level sensor, a tire pressure sensor or a vehicle location device.

Dans ce système de contrôle connu, chaque véhicule comprend également une unité centrale apte à émettre un message vers le serveur central, au travers du réseau de télécommunication, ce message contenant les paramètres collectés.In this known control system, each vehicle also comprises a central unit capable of transmitting a message to the central server, through the telecommunications network, this message containing the parameters collected.

Un tel système permet à un constructeur automobile de constituer une base de données le renseignant sur la gestion propre de chaque véhicule, pour un entretien optimal de ce véhicule, et également sur la gestion globale du parc de véhicules, permettant par exemple une prévision de l'approvisionnement en pièces de rechange. Ce système assure un suivi de meilleure qualité des véhicules après leur achat. Il permet en particulier la détection d'une défaillance ou de l'usure d'un élément du véhicule mais ne permet toutefois pas de prévenir les dysfonctionnements du véhicule, en analysant la cause de ceux-ci.Such a system allows a car manufacturer to build a database providing information on the own management of each vehicle, for optimal maintenance of the vehicle, and also on the overall management of the vehicle fleet, allowing for example a forecast of the vehicle. supply of spare parts. This system ensures a better follow-up of the vehicles after their purchase. It allows in particular the detection of a failure or wear of a vehicle element but does not however prevent the malfunctions of the vehicle, analyzing the cause thereof.

On sait notamment qu'un carburant (essence, gazole, GPL, etc.) peut causer des perturbations du moteur, voire une panne du véhicule automobile, si sa qualité est insuffisante. Ces perturbations peuvent entraîner des coûts de réparation très élevés, notamment dans le cas où la mauvaise qualité du carburant est généralisée.It is known in particular that a fuel (gasoline, diesel, LPG, etc.) can cause engine disturbances, or even a breakdown of the motor vehicle, if its quality is insufficient. These disturbances can lead to very high repair costs, especially in the case where the poor quality of the fuel is widespread.

Il serait donc intéressant, pour un constructeur automobile, d'être en mesure de contrôler la qualité du carburant distribué par chaque distributeur (une station service, une chaîne de stations service, etc.), afin d'assurer une surveillance générale des sources de carburant. Le constructeur pourrait alors agir en amont de l'alimentation en carburant, de façon à éviter des dysfonctionnements du véhicule.It would therefore be interesting for a car manufacturer to be able to control the quality of the fuel dispensed by each distributor (a service station, a chain of service stations, etc.), in order to ensure a general monitoring of the sources of fuel. fuel. The manufacturer could then act upstream of the fuel supply, so as to avoid malfunctions of the vehicle.

Toutefois, il n'existe pas aujourd'hui de système simple permettant au constructeur de s'assurer de la qualité du carburant distribué.However, today there is no simple system allowing the manufacturer to ensure the quality of the fuel dispensed.

L'invention a pour but de remédier à cet inconvénient en fournissant un système mettant à la disposition du constructeur automobile des données relatives à la qualité du carburant distribué par chaque distributeur.The invention aims to overcome this disadvantage by providing a system providing the car manufacturer data on the quality of the fuel distributed by each distributor.

A cet effet, l'invention a pour objet un système de contrôle de la qualité de carburant distribué, remarquable en ce que ledit système comprend :

  • dans un véhicule automobile :
    • * un capteur de mesure d'au moins un paramètre lié à la qualité du carburant,
    • * un dispositif de localisation du véhicule,
    • * une unité centrale, apte, d'une part, à recevoir une mesure de qualité fournie par ledit capteur et une information de localisation du lieu de distribution du carburant, fournie par ledit dispositif de localisation, et, d'autre part, à émettre, à travers un réseau de télécommunication, un message contenant ladite mesure de qualité du carburant distribué et ladite information de localisation du lieu de distribution du carburant,
  • un serveur central, apte à recevoir le message émis par l'unité centrale à travers le réseau de télécommunication.
For this purpose, the subject of the invention is a distributed fuel quality control system, remarkable in that said system comprises:
  • in a motor vehicle:
    • a sensor for measuring at least one parameter related to the quality of the fuel,
    • * a device for locating the vehicle,
    • a central unit, able, on the one hand, to receive a measurement of quality provided by said sensor and information of location of the fuel distribution place, provided by said locating device, and, on the other hand, to transmit through a telecommunication network, a message containing said distributed fuel quality measurement and said location information of the fuel distribution location,
  • a central server, able to receive the message sent by the central unit through the telecommunication network.

Ainsi, chaque véhicule est équipé d'un dispositif de contrôle autonome de la qualité du carburant, à l'aide duquel il peut transmettre à une entité extérieure au véhicule des données concernant le carburant, sans intervention de l'utilisateur du véhicule. A partir des données reçues par l'entité extérieure, le constructeur automobile peut construire une base de données relative aux différentes sources de carburant.Thus, each vehicle is equipped with an autonomous control device of the fuel quality, with which it can transmit data to a non-vehicle entity about the fuel without the intervention of the user of the vehicle. From the data received by the external entity, the car manufacturer can build a database of different fuel sources.

A l'aide de ces données, le constructeur est donc capable de prendre des mesures évitant aux véhicules qu'il produit les désagréments liés à un carburant de mauvaise qualité. Il peut par exemple avertir les utilisateurs de véhicule automobile d'éviter d'alimenter leur véhicule en carburant chez un distributeur donné, mettre en place des retours d'informations vers les compagnies pétrolières ou mener des actions préventives pour préserver les véhicules s'il constate que la qualité insuffisante du carburant est généralisée.With the help of these data, the manufacturer is able to take measures to avoid the vehicles he produces the inconvenience associated with a poor quality fuel. It can, for example, warn motor vehicle users to avoid fueling their vehicles at a given distributor, set up feedback to oil companies or take preventive action to preserve vehicles if it finds that the insufficient quality of the fuel is generalized.

Un tel système permet donc la diminution du nombre de dysfonctionnements de véhicules automobiles liés à un carburant de mauvaise qualité. Le constructeur peut ainsi assurer plus efficacement le service après-vente du véhicule, augmentant le taux de satisfaction des utilisateurs et économiser les coûts de garantie.Such a system therefore reduces the number of malfunctions of motor vehicles related to a poor quality fuel. The manufacturer can thus more effectively service the vehicle after-sales service, increasing the user satisfaction rate and saving warranty costs.

Avantageusement, le serveur central est apte à établir une cartographie de la qualité du carburant distribué. De cette manière, il est possible pour le constructeur de représenter la répartition des carburants de mauvaise qualité par secteur géographique de façon facilement compréhensible, et de repérer une mauvaise qualité du carburant généralisée.Advantageously, the central server is able to establish a map of the quality of the fuel dispensed. In this way, it is possible for the manufacturer to represent the distribution of poor quality fuels by geographical area in an easily understandable manner, and to identify poor generalized fuel quality.

Selon un mode de réalisation, l'unité centrale comprend des moyens de stockage de données et est apte à inscrire des données dans les moyens de stockage.According to one embodiment, the central unit comprises data storage means and is able to register data in the storage means.

Ainsi, l'unité centrale a la possibilité d'inscrire les données fournies par le capteur de mesure et le dispositif de localisation dans les moyens de stockage, ce qui lui permet d'émettre un message vers le serveur central selon un horaire choisi, par exemple lorsque le réseau de télécommunication est peu encombré, et non dès que le véhicule a été alimenté en carburant. Le système est alors plus fiable, minimisant la perte de données.Thus, the central unit has the possibility of recording the data provided by the measurement sensor and the location device in the storage means, which enables it to send a message to the central server according to a schedule chosen by example when the telecommunication network is not crowded, and not as soon as the vehicle has been fueled. The system is then more reliable, minimizing data loss.

Dans ce contexte, l'invention prévoit par ailleurs que le message émis par l'unité centrale vers le serveur central contient une date et une heure et/ou un identifiant du véhicule automobile. Le serveur central peut donc avoir accès à des données supplémentaires, permettant au constructeur automobile de relier chaque véhicule avec son historique de carburant afin de mieux assurer le suivi au cas par cas des véhicules automobiles et mieux comprendre en général quel défaut de carburant peut causer une panne de type donné.In this context, the invention further provides that the message sent by the central unit to the central server contains a date and a time and / or an identifier of the motor vehicle. The central server can therefore have access to additional data, allowing the car manufacturer to link each vehicle with its fuel history to better ensure the case-by-case follow-up of motor vehicles and better understand in general what fuel fault can cause a given type of breakdown.

Il est également prévu par l'invention que l'unité centrale est apte à comparer une valeur d'un paramètre, fournie par le capteur, avec une valeur de consigne de ce paramètre. L'unité centrale a alors la possibilité d'émettre un message vers le serveur central uniquement si le capteur détecte que la qualité du carburant est insuffisante. Le serveur central n'est alors pas surchargé de données inutiles, c'est-à-dire non susceptibles d'entraîner des dysfonctionnements des véhicules automobiles.It is also provided by the invention that the central unit is able to compare a value of a parameter, provided by the sensor, with a set value of this parameter. The central unit can then send a message to the central server only if the sensor detects that the quality of the fuel is insufficient. The central server is then not overloaded with unnecessary data, that is to say, not likely to cause malfunctions of motor vehicles.

Dans un mode de réalisation particulier, l'unité centrale est apte à communiquer des données à au moins un dispositif externe, disposé dans le véhicule automobile. Ce dispositif externe peut être par exemple le dispositif de contrôle moteur.In a particular embodiment, the central unit is able to communicate data to at least one external device disposed in the motor vehicle. This external device may be for example the engine control device.

Ainsi, le dispositif externe, dont le fonctionnement dépend de la qualité du carburant, est averti de la nature du carburant et s'adapte au mieux à celui-ci en fonction des paramètres qui lui sont communiqués. Ce mode de réalisation permet de minimiser les dysfonctionnements du véhicule, même lorsque le véhicule a d'ores et déjà été alimenté avec un carburant de qualité insuffisante.Thus, the external device, the operation of which depends on the quality of the fuel, is informed of the nature of the fuel and best adapts to it according to the parameters communicated to it. This embodiment minimizes vehicle malfunctions, even when the vehicle has already been fed with a fuel of insufficient quality.

Selon une caractéristique avantageuse de l'invention, le serveur central est apte à émettre un message comprenant des données à destination de l'unité centrale. De cette manière, le constructeur automobile est capable d'émettre des instructions vers le véhicule automobile. Ces instructions lui permettent d'agir à distance sur le véhicule et de remédier plus rapidement et plus efficacement à d'éventuelles défaillances de celui-ci.According to an advantageous characteristic of the invention, the central server is able to transmit a message comprising data destined for the central unit. In this way, the car manufacturer is able to issue instructions to the motor vehicle. These instructions allow him to act remotely on the vehicle and to remedy more quickly and more effectively any failures thereof.

Selon un mode de réalisation, les données émises par le serveur comprennent au moins un élément pris dans la liste suivante :

  • une requête d'émission de message par l'unité centrale vers le serveur,
  • une valeur de consigne associée à un paramètre mesuré par le capteur,
  • une valeur d'une variable du dispositif externe.
According to one embodiment, the data transmitted by the server comprises at least one element taken from the following list:
  • a message transmission request by the central unit to the server,
  • a reference value associated with a parameter measured by the sensor,
  • a value of a variable of the external device.

De même, l'invention prévoit que le capteur mesure au moins l'un des paramètres pris dans la liste suivante :

  • pression de vapeur,
  • composition chimique,
  • courbe de distillation,
  • indice de cétane,
  • teneur en oxygène.
Similarly, the invention provides that the sensor measures at least one of the parameters taken from the following list:
  • vapor pressure,
  • chemical composition,
  • distillation curve,
  • cetane number,
  • oxygen content.

Dans un premier mode de réalisation, le dispositif de localisation est un dispositif de localisation par satellite, tel que GPS (Global Positioning System) ou GALILEO (marque déposée par EADS).In a first embodiment, the location device is a satellite location device, such as GPS (Global Positioning System) or GALILEO (registered trademark by EADS).

Dans un second mode de réalisation, le dispositif de localisation est un dispositif de localisation par bornes terrestres, tel que GSM (Global System for Mobile communication).In a second embodiment, the location device is a terrestrial terminal location device, such as GSM (Global System for Mobile Communication).

L'invention a également pour objet un serveur central appartenant au système selon l'invention.The invention also relates to a central server belonging to the system according to the invention.

L'invention a également pour objet un véhicule automobile remarquable en ce que ledit véhicule comprend :

  • un capteur de mesure d'au moins un paramètre lié à la qualité du carburant ;
  • un dispositif de localisation du véhicule ;
  • une unité centrale, apte, d'une part, à recevoir une mesure de qualité fournie par ledit capteur et une information de localisation du lieu de distribution du carburant, fournie par ledit dispositif de localisation, et, d'autre part, à émettre, à travers un réseau de télécommunication, un message contenant ladite mesure de qualité du carburant distribué et ladite information de localisation du lieu de distribution du carburant.
The invention also relates to a remarkable motor vehicle in that said vehicle comprises:
  • a sensor for measuring at least one parameter related to the quality of the fuel;
  • a device for locating the vehicle;
  • a central unit, able, on the one hand, to receive a quality measurement provided by said sensor and a location information of the fuel distribution place, provided by said locating device, and, on the other hand, to transmit, through a telecommunication network, a message containing said distributed fuel quality measurement and said location information of the fuel distribution place.

La description qui va suivre en regard du dessin annexé, donné à titre d'exemple non limitatif, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.The following description with reference to the accompanying drawing, given by way of non-limiting example, will make it clear what the invention is and how it can be achieved.

Sur la figure unique est représenté un système 10 de contrôle de la qualité de carburant, comprenant un serveur central 12, relié par un réseau 14 de télécommunication adapté au transport de données, à au moins un véhicule automobile 16.The single figure shows a fuel quality control system 10, comprising a central server 12, connected by a telecommunication network 14 adapted to data transport, to at least one motor vehicle 16.

Le serveur central 12 comprend de façon classique des moyens de calcul, tel qu'un microprocesseur, et une mémoire de type non volatile, permettant le stockage d'une base de données relative à la qualité du carburant.The central server 12 conventionally comprises calculation means, such as a microprocessor, and a non-volatile type of memory, for storing a database relating to the quality of the fuel.

Le système 10 comprend également un dispositif 20 de localisation installé dans le véhicule 16.The system 10 also includes a locating device 20 installed in the vehicle 16.

Ce dispositif peut être un dispositif de localisation par satellite, tel que GPS (Global Positioning Sytem) ou GALILEO (marque déposée par EADS).This device can be a satellite positioning device, such as GPS (Global Positioning Sytem) or GALILEO (trademark registered by EADS).

Il peut également être un dispositif de localisation par bornes terrestres, tel que GSM (Global System for Mobile Communication).It can also be a device for localization by land terminals, such as GSM (Global System for Mobile Communication).

L'unité centrale 22 comporte également un bus 25 de communication permettant la liaison au capteur 18 et au dispositif 20 de localisation, ainsi qu'à au moins un dispositif externe du véhicule automobile, comme le dispositif 26 de contrôle moteur, régulant le fonctionnement du moteur en fonction de variables d'entrée.The central unit 22 also comprises a communication bus 25 enabling the connection to the sensor 18 and to the locating device 20, as well as to at least one external device of the motor vehicle, such as the motor control device 26, regulating the operation of the device. motor based on input variables.

Le bus 25 de communication peut être de tout type : CAN, MOST, 1394, etc.The communication bus can be of any type: CAN, MOST, 1394, etc.

Ainsi, lorsque l'utilisateur du véhicule 16 alimente son véhicule en carburant, l'unité centrale 22 reçoit, via le bus 25, la mesure de la qualité du carburant distribué, c'est-à-dire la valeur d'un paramètre mesurée par le capteur 18, et également la localisation du lieu de distribution du carburant fournie par le dispositif 20.

L'unité centrale effectue alors une comparaison entre la valeur du paramètre mesurée par le capteur 18 et une valeur de consigne de ce paramètre stockée dans les moyens 24 et constituant un indicateur de la qualité du carburant.The central unit then makes a comparison between the value of the parameter measured by the sensor 18 and a set value of this sensor. parameter stored in the means 24 and constituting an indicator of the quality of the fuel.

Si cette comparaison indique que la qualité du carburant est bonne, le véhicule 16 efface les données reçues des moyens de stockage 24.If this comparison indicates that the fuel quality is good, the vehicle 16 erases the data received from the storage means 24.

En revanche, si la qualité du carburant est considérée comme insuffisante, l'unité centrale 22 émet un message vers le serveur central 12, à travers le réseau 14 de télécommunication, ce message comportant la mesure de la qualité du carburant et la localisation du lieu de distribution, ainsi qu'une heure et une date, correspondant à l'émission ou à l'enregistrement des données, ainsi qu'un identifiant du véhicule.On the other hand, if the quality of the fuel is considered insufficient, the central unit 22 sends a message to the central server 12, through the telecommunication network 14, this message including the measurement of the quality of the fuel and the location of the place of distribution, as well as a time and a date, corresponding to the emission or the recording of the data, as well as a vehicle identifier.

Le serveur central 12 reçoit ensuite le message qu'il analyse à l'aide des moyens de calcul, pour déterminer quel est le distributeur du carburant contenu dans le véhicule 16.The central server 12 then receives the message that it analyzes using the calculation means, to determine which is the distributor of the fuel contained in the vehicle 16.

Le serveur central 12 stocke alors les données transmises dans sa mémoire, ce qui permet de mettre à jour la base de données du constructeur automobile et les moyens de calcul du serveur 12 établissent une cartographie de la qualité du carburant en fonction des données de la base de données mise à jour.The central server 12 then stores the data transmitted in its memory, which makes it possible to update the database of the automobile manufacturer and the calculation means of the server 12 establish a map of the quality of the fuel according to the data of the database. updated data.

Le serveur central 12 peut également émettre un message vers le véhicule 16, au travers du réseau 14 de communication, si le constructeur automobile souhaite agir directement sur le véhicule automobile 16.The central server 12 can also send a message to the vehicle 16, through the communication network 14, if the car manufacturer wishes to act directly on the motor vehicle 16.

Dans ce cas, le serveur 12 émet un message à destination du véhicule 16, ce message comprenant une valeur pour une variable du dispositif du contrôle moteur à modifier et une nouvelle valeur de consigne du paramètre mesuré.In this case, the server 12 sends a message to the vehicle 16, this message comprising a value for a variable of the engine control device to be modified and a new setpoint value of the measured parameter.

A la réception de ce message, l'unité centrale 22 stocke la nouvelle valeur de consigne dans les moyens 24 de stockage et communique, via le bus 25, la valeur de la variable à modifier au dispositif 26 de contrôle moteur.On receipt of this message, the central unit 22 stores the new setpoint value in the storage means 24 and communicates, via the bus 25, the value of the variable to be modified to the motor control device 26.

Ainsi, un constructeur automobile dispose d'une entité de surveillance de la qualité du carburant, lui permettant de prévenir des pannes généralisées et également d'agir sur chaque véhicule au cas par cas, pour éviter tous dysfonctionnements.Thus, a car manufacturer has a fuel quality monitoring entity, allowing it to prevent widespread failures and also to act on each vehicle on a case by case basis, to avoid any malfunctions.

En variante, l'unité centrale 22 du véhicule 16 peut envoyer un message directement après l'alimentation du véhicule en carburant ou sur demande du serveur central 12, sans effectuer de comparaison. En outre, l'unité centrale 22 peut communiquer au dispositif 26 de contrôle moteur la valeur mesurée par le capteur 18, ce dispositif 26 modifiant la valeur de ses variables en fonction de la valeur transmise.Alternatively, the central unit 22 of the vehicle 16 can send a message directly after the fuel supply of the vehicle or at the request of the central server 12, without making a comparison. In addition, the central unit 22 can communicate to the motor control device 26 the value measured by the sensor 18, this device 26 modifying the value of its variables as a function of the value transmitted.
