Description

PROCEDE ET DISPOSITIF DE COMMUNICATION INTER- VEHICULES La présente invention concerne de manière générale un procédé de communication inter-véhicules destiné à être mis en oeuvre sur un véhicule automobile. Il est connu dans l'art antérieur des procédés et des dispositifs de 5 communication inter-véhicules agencés de sorte à permettre à un conducteur de communiquer avec des véhicules environnants. De manière générale, ces dispositifs sont agencés de sorte à être actionnés par le conducteur lorsque celui-ci le juge nécessaire en fonction d'une situation de circulation. Un message visuel visible par les véhicules est alors diffusé. Un problème de ce 10 type de dispositif et de procédé est qu'il met en oeuvre une action du conducteur et qu'il ne consiste pas exactement en une aide à la conduite mais en un moyen d'interaction inter-véhicules qui peut être détourné et nuire à la sécurité. De plus, l'attention et la concentration du conducteur sont détournées de la route lorsqu'il doit actionner le dispositif de communication. 15 Le document FR 2 955 410 décrit un procédé et un dispositif de communication inter-véhicules dans lequel un passager doit d'abord enregistrer une information, puis la diffuser de sorte à la communiquer aux véhicules avoisinants. Un inconvénient de ce procédé et du dispositif qui le met en oeuvre est qu'il détourne l'attention du conducteur de la route lorsqu'il 20 doit enregistrer l'information. Un but de la présente invention est de répondre aux inconvénients mentionnés ci-dessus et en particulier, tout d'abord, de fournir un procédé et un dispositif de communication inter-véhicules simple à mettre en oeuvre et permettant au conducteur de rester concentré sur la route.The present invention relates generally to a method of inter-vehicle communication for use in a motor vehicle. Prior art is known in the art of inter-vehicle communication methods and devices arranged to enable a driver to communicate with surrounding vehicles. In general, these devices are arranged to be operated by the driver when he deems it necessary according to a traffic situation. A visual message visible by the vehicles is then broadcast. A problem with this type of device and method is that it implements driver action and is not exactly a driver assistance but an inter-vehicle interaction means that can be diverted. and undermine security. In addition, the attention and the concentration of the driver are diverted from the road when he must operate the communication device. Document FR 2 955 410 describes a method and an inter-vehicle communication device in which a passenger must first record information and then broadcast it so as to communicate it to neighboring vehicles. A disadvantage of this method and the device which implements it is that it distracts the driver's attention from the road when he has to record the information. An object of the present invention is to meet the drawbacks mentioned above and in particular, first of all, to provide a method and an inter-vehicle communication device that is simple to implement and allows the driver to remain focused on the road.

Pour cela un premier aspect de l'invention concerne un procédé de communication inter-véhicules mis en oeuvre sur un véhicule automobile comprenant les étapes de mesure d'une condition de circulation à l'arrière du véhicule, de détermination que la condition de circulation mesurée à l'arrière 5 du véhicule est une condition de circulation critique, de sélection automatique d'une information prédéterminée devant être communiquée à un autre véhicule en fonction de ladite condition de circulation critique, d'affichage de ladite information à un conducteur du véhicule, de détection d'un accord dudit conducteur sur ladite information affichée, de réception de l'accord 10 dudit conducteur sur ladite information affichée, et d'affichage de ladite information sur un élément de structure du véhicule pour la communiquer à l'autre véhicule. De cette manière, il est possible pour un conducteur d'avertir un autre véhicule d'une situation de circulation critique sans qu'il ait à détourner son attention de la circulation. 15 De manière avantageuse, la condition de circulation à l'arrière du véhicule est une distance inter-véhicules avec l'autre véhicule. Ainsi, il est possible d'avertir un autre véhicule qui roule trop près. Une réalisation particulièrement intéressante consiste en ce que l'étape de détermination d'une condition de circulation critique détermine 20 ladite condition de circulation critique lorsque ladite distance inter-véhicules est inférieure à un seuil prédéterminé en fonction de la vitesse dudit véhicule. De cette manière, il est effectué une discrimination des situations critiques en fonction de la dangerosité effective de la situation. Avantageusement, ladite information est affichée au conducteur via 25 une projection de ladite information sur un film réfléchissant agencé sur le pare-brise avant au moyen d'un pico-projecteur avant. De cette manière, le conducteur n'a pas à détourner son regard de la route. On peut envisager d'utiliser un film réfléchissant, semi réfléchissant ou partiellement opaque ou translucide pour projeter sur le pare brise. 30 De manière avantageuse, l'étape de détection d'un accord dudit conducteur consiste à détecter un mouvement prédéterminé du visage du conducteur au moyen d'une caméra avant. Ainsi, le conducteur n'a pas à actionner physiquement un instrument d'entrée de données. Alternativement, l'étape de détection d'un accord dudit conducteur consiste à détecter un message vocal prédéterminé du conducteur au moyen 5 d'un microphone. Ainsi, le conducteur n'a pas à détourner son regard de la route. Avantageusement, l'étape d'affichage de l'information sur un élément de structure du véhicule pour la communiquer à l'autre véhicule consiste en une projection, au moyen d'un pico-projecteur arrière, de ladite information 10 sur un film réfléchissant agencé sur le pare brise arrière. De cette manière, l'information est bien visible pour les véhicules situés à l'arrière du véhicule. On peut envisager d'utiliser un film réfléchissant, semi réfléchissant ou partiellement opaque ou translucide pour projeter sur le pare brise arrière. De manière avantageuse, le procédé comprend en outre une étape de 15 vérification de la condition de circulation après la communication de l'information. Ainsi, il peut être vérifié que l'autre véhicule ait reçu le message. Un second aspect de l'invention est un dispositif de communication inter-véhicules comprenant un moyen de mesure d'une condition de 20 circulation à l'arrière du véhicule, un moyen de détermination que la condition de circulation mesurée à l'arrière du véhicule est une condition de circulation critique, un moyen de sélection automatique d'une information prédéterminée devant être communiquée à un autre véhicule en fonction de ladite condition de circulation critique, un moyen d'affichage de ladite 25 information à un conducteur du véhicule, un moyen de détection d'un accord dudit conducteur sur ladite information affichée, un moyen de réception de l'accord dudit conducteur sur ladite information affichée, et un moyen d'affichage de ladite information sur un élément de structure du véhicule pour la communiquer à l'autre véhicule selon le premier aspect de l'invention.For this purpose, a first aspect of the invention concerns an inter-vehicle communication method implemented on a motor vehicle comprising the steps of measuring a traffic condition at the rear of the vehicle, determining that the measured circulation condition at the rear of the vehicle is a critical circulation condition, automatic selection of a predetermined information to be communicated to another vehicle according to said critical traffic condition, display of said information to a driver of the vehicle, detecting an agreement of said driver on said displayed information, receiving the agreement of said driver on said displayed information, and displaying said information on a structural element of the vehicle to communicate it to the other vehicle. In this way, it is possible for a driver to warn another vehicle of a critical traffic situation without having to divert his attention from traffic. Advantageously, the traffic condition at the rear of the vehicle is an inter-vehicle distance with the other vehicle. Thus, it is possible to warn another vehicle that is driving too close. A particularly interesting embodiment is that the step of determining a critical traffic condition determines said critical traffic condition when said inter-vehicle distance is below a predetermined threshold as a function of the speed of said vehicle. In this way, it is discriminated against critical situations according to the actual dangerousness of the situation. Advantageously, said information is displayed to the driver via a projection of said information on a reflective film arranged on the front windshield by means of a front pico-projector. In this way, the driver does not have to look away from the road. One can consider using a reflective film, semi-reflective or partially opaque or translucent to project on the windshield. Advantageously, the step of detecting a chord of said conductor is to detect a predetermined movement of the driver's face by means of a front camera. Thus, the driver does not have to physically operate a data entry instrument. Alternatively, the step of detecting a chord of said conductor is to detect a predetermined voice message of the conductor by means of a microphone. Thus, the driver does not have to look away from the road. Advantageously, the step of displaying the information on one structural element of the vehicle to communicate it to the other vehicle consists of a projection, by means of a rear pico-projector, of said information on a reflective film. arranged on the rear windshield. In this way, the information is clearly visible for vehicles located at the rear of the vehicle. One can consider using a reflective film, semi-reflective or partially opaque or translucent to project on the rear windshield. Advantageously, the method further comprises a step of checking the circulation condition after the communication of the information. Thus, it can be verified that the other vehicle has received the message. A second aspect of the invention is an inter-vehicle communication device comprising means for measuring a traffic condition at the rear of the vehicle, a means for determining that the traffic condition measured at the rear of the vehicle is a critical traffic condition, a means for automatically selecting a predetermined information to be communicated to another vehicle according to said critical traffic condition, means for displaying said information to a vehicle driver, a means for detecting an agreement of said driver on said displayed information, means for receiving the agreement of said driver on said displayed information, and means for displaying said information on a structural element of the vehicle to communicate it to the another vehicle according to the first aspect of the invention.

Un troisième aspect de l'invention est un véhicule comprenant un dispositif de communication inter-véhicules selon le second aspect de l'invention. D'autres caractéristiques et avantages de la présente invention 5 apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels : - la figure 1 représente un véhicule doté d'un dispositif de communication inter-véhicules de la présente invention agencé 10 pour mettre en oeuvre le procédé de communication inter-véhicules de la présente invention. La figure 1 représente un dispositif de communication inter-véhicules de la présente invention qui comprend un moyen de mesure 2 d'une condition de circulation à l'arrière du véhicule, un moyen de détermination 3 15 que la condition de circulation mesurée à l'arrière du véhicule est une condition de circulation critique, un moyen de sélection automatique 3 d'une information prédéterminée, un moyen d'affichage 4 de ladite information à un conducteur du véhicule, un moyen de détection 5, 5' d'un accord dudit conducteur sur ladite information affichée, un moyen de réception 5, 5' de 20 l'accord dudit conducteur sur ladite information affichée, et un moyen d'affichage 6 de ladite information sur un élément de structure du véhicule. Plus particulièrement, ce dispositif comprend de préférence une caméra arrière 2 comme moyen de mesure d'une condition de circulation à l'arrière du véhicule de sorte à pouvoir mesurer, par exemple, une distance 25 inter-véhicules entre le véhicule portant le dispositif et un autre véhicule suivant le véhicule portant le dispositif. L'image prise par la caméra arrière 2 est envoyée à une unité centrale 3 qui fonctionne comme moyen de détermination que la condition de circulation mesurée à l'arrière du véhicule est une condition de circulation critique lorsque la distance inter-véhicules est inférieure à un seuil prédéterminé en fonction de la vitesse dudit véhicule. Lors qu'une telle situation de circulation critique est déterminée, l'unité centrale 3, qui comprend également un moyen de sélection automatique d'une information prédéterminée, sélectionne une information prédéterminée choisie dans une base de données en fonction de ladite condition de circulation critique détectée, devant être communiquée à l'autre véhicule. Une fois cette information prédéterminée sélectionnée, elle est affichée au conducteur via une projection de ladite information sur un film réfléchissant ou partiellement réfléchissant, ou partiellement opaque ou translucide agencé sur le pare-brise avant au moyen d'un pico-projecteur 4. Le conducteur doit alors donner son accord sur l'information affichée. Pour cela, le dispositif comprend un moyen de détection comprenant une caméra avant 5 et/ou un microphone 5' qui détectent un mouvement prédéterminé du visage du conducteur et/ou un message vocal prédéterminé du conducteur, respectivement, et reçoivent l'accord dudit conducteur sur ladite information affichée. Une fois l'accord reçu, l'information est affichée sur un élément de structure du véhicule, par exemple au moyen d'un pico-projecteur arrière 6 sur un film transparent et réfléchissant ou partiellement réfléchissant, ou partiellement opaque ou translucide agencé sur le pare-brise arrière, pour la communiquer à l'autre véhicule. Enfin, une fois l'information affichée, la caméra arrière 2 continue de mesurer la condition de circulation de sorte à continuer ou arrêter l'affichage 25 de l'information en fonction de l'évolution de la situation de circulation critique. On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention décrits dans la présente description sans 30 sortir du cadre de l'invention défini par les revendications annexées. En particulier, il est fait référence aux types de situation critique détectée, aux différents types de véhicules, et aux types d'informations affichées.A third aspect of the invention is a vehicle comprising an inter-vehicle communication device according to the second aspect of the invention.
