DESCRIPTION DESCRIPTION
TITRE : Procédé de gestion du fonctionnement d’un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile, système et véhicule automobile associés TITLE: Method for managing the operation of an apparatus for monitoring the driving environment of a motor vehicle, associated system and motor vehicle
La présente invention revendique la priorité de la demande française 2103821 déposée le 14.04.2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence The present invention claims the priority of French application 2103821 filed on 04.14.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
Domaine technique de l’invention Technical field of the invention
L’invention concerne le domaine des systèmes et dispositifs embarqués à bord des véhicules automobiles pour permettre aux conducteurs de surveiller l’environnement de conduite durant la conduite. L’invention porte en particulier sur un procédé de gestion du fonctionnement d’un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile, ledit appareillage comprenant un premier écran agencé à gauche du poste de conduite dans l’habitacle du véhicule, un deuxième écran agencé à droite du poste de conduite dans l’habitacle du véhicule, une première caméra agencée sur le côté gauche de la carrosserie du véhicule pour réaliser des prises de vues d’au moins un espace situé derrière le véhicule et sur son côté gauche et une deuxième caméra agencée sur le côté droit de la carrosserie du véhicule pour réaliser des prises de vues d’au moins un espace situé derrière le véhicule et sur son côté droit. L’invention concerne également un système informatique mettant en œuvre un tel procédé. L’invention s’applique, notamment, aux voitures. État de la technique antérieure The invention relates to the field of systems and devices on board motor vehicles to enable drivers to monitor the driving environment while driving. The invention relates in particular to a method for managing the operation of an apparatus for monitoring the driving environment of a motor vehicle, said apparatus comprising a first screen arranged to the left of the driving position in the passenger compartment of the vehicle , a second screen arranged to the right of the driving position in the passenger compartment of the vehicle, a first camera arranged on the left side of the bodywork of the vehicle to take shots of at least one space located behind the vehicle and on its left side and a second camera arranged on the right side of the body of the vehicle to take shots of at least one space located behind the vehicle and on its right side. The invention also relates to a computer system implementing such a method. The invention applies, in particular, to cars. State of the prior art
On sait que les véhicules automobiles ont été traditionnellement équipés de rétroviseurs à miroirs pour permettre aux conducteurs de surveiller l’environnement de conduite au cours de la conduite. On sait aussi, notamment de la demande de brevet FR3100178, que, dans certains véhicules actuels, des appareillages de surveillance de l’environnement de conduite formés de rétroviseurs dits numériques utilisent caméras et écrans pour remplacer les traditionnels rétroviseurs à miroir. It is known that motor vehicles have traditionally been equipped with mirrored rearview mirrors to allow drivers to monitor the driving environment while driving. We also know, in particular from patent application FR3100178, that, in certain current vehicles, devices for monitoring the driving environment made up of so-called digital mirrors use cameras and screens to replace traditional mirror mirrors.
Mais, il s’avère que même ces appareillages de surveillance de l’environnement de conduite modernes n’apportent pas solution à tous les problèmes. En particulier, chacun sait que, en marche arrière, le conducteur d’un véhicule muni de traditionnels rétroviseurs à miroir doit prendre connaissance de l’environnement de conduite en regardant successivement l’un et l’autre des rétroviseurs latéraux, ce qui implique qu’il existe des instants pendant lesquels le conducteur n’est pas en mesure de surveiller l’un ou l’autre des côtés du véhicule, ce qui engendre indéniablement un risque d’accident. Et, sur ce point, les systèmes de surveillance modernes, notamment celui décrit dans la demande de brevet précitée, n’apportent aucune solution. Résumé de l’invention But it turns out that even these modern driving environment monitoring devices do not solve all the problems. In particular, everyone knows that, in reverse, the driver of a vehicle equipped with traditional mirror mirrors must become aware of the driving environment by looking successively at one and the other of the side mirrors, which implies that There are times during which the driver is unable to monitor one or other of the sides of the vehicle, which undeniably creates a risk of accident. And, on this point, modern surveillance systems, in particular the one described in the aforementioned patent application, do not provide any solution. Summary of the invention
L’invention vise à pallier cet inconvénient. L’invention a en effet pour but de fournir un procédé et un système qui contribuent pour permettre de minimiser le risque d’accident lors de manœuvres réalisées en marche arrière. L’invention vise en particulier à fournir un procédé et un système qui permettent à un appareillage de surveillance de l’environnement de conduite de fournir plus d’ergonomie en matière de surveillance de l’environnement conduite lors de manœuvres réalisées en marche arrière, pour notamment éviter au conducteur de devoir, de manière successive, renoncer à surveiller l’un ou l’autre des deux côtés du véhicules. Par ce biais, l’invention vise à fournir un procédé et un système qui contribuent pour améliorer la sécurité de la conduite. The invention aims to overcome this drawback. The object of the invention is in fact to provide a method and a system which contribute to making it possible to minimize the risk of accident during maneuvers performed in reverse. The invention aims in particular to provide a method and a system which allow an apparatus for monitoring the driving environment to provide more ergonomics in terms of monitoring the driving environment during maneuvers carried out in reverse, for in particular to avoid the driver having to successively give up monitoring one or the other of the two sides of the vehicle.

Selon d’autres modes de réalisation, le système 100 selon l’invention est hébergé sur un calculateur d’un véhicule automobile et il interagit par le biais de son interface d’entrée et sortie 103 avec un calculateur d’un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile. Selon le mode de réalisation préféré, le système 100 selon l’invention fait partie intégrante d’un calculateur d’un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile. Par conséquent, quel que soit le mode de réalisation de l’invention, le système 100 selon l’invention est en mesure d’interagir, par le biais de son interface d’entrée et sortie 103, avec les composants qui, de manière conventionnelle, forment un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile. Selon l’invention, ces composants incluent, au moins, un premier écran agencé à gauche du poste de conduite dans l’habitacle du véhicule, un deuxième écran agencé à droite du poste de conduite dans l’habitacle du véhicule, une première caméra agencée sur le côté gauche de la carrosserie du véhicule pour réaliser des prises de vues d’au moins un espace situé derrière le véhicule et sur son côté gauche et une deuxième caméra agencée sur le côté droit de la carrosserie du véhicule pour réaliser des prises de vues d’au moins un espace situé derrière le véhicule et sur son côté droit. Ainsi, en interagissant avec ou en faisant partie intégrante d’un tel appareillage, le système 100 selon l’invention est avantageusement en mesure de provoquer la diffusion d’une image créée à partir de données générées par une caméra sur une portion de chacun des écrans. According to the invention, a system 100 for managing the operation of an apparatus for monitoring the driving environment of a motor vehicle is a computer system, represented in FIG. 1, which comprises an information processing unit 101 , comprising one or more processors, a data storage medium 102 and an input and output interface 103 allowing the reception and transmission of data. According to certain embodiments, the system 100 according to the invention is embedded in a motor vehicle (eg car, bus, truck, etc.) and it is hosted on one or more of the computers, electronic control units or other telematics boxes of the vehicle. According to other embodiments, the system 100 according to the invention is hosted on a computer of a motor vehicle and it interacts through its input and output interface 103 with a computer of a monitoring device of the driving environment of a motor vehicle. According to the preferred embodiment, the system 100 according to the invention forms an integral part of a computer of an apparatus for monitoring the driving environment of a motor vehicle. Consequently, whatever the embodiment of the invention, the system 100 according to the invention is able to interact, through its input and output interface 103, with the components which, conventionally , form an apparatus for monitoring the driving environment of a motor vehicle. According to the invention, these components include, at least, a first screen arranged to the left of the driving position in the passenger compartment of the vehicle, a second screen arranged to the right of the driving position in the passenger compartment of the vehicle, a first camera arranged on the left side of the body of the vehicle to take shots of at least one space located behind the vehicle and on its left side and a second camera arranged on the right side of the body of the vehicle to take shots at least one space located behind the vehicle and on its right side. Thus, by interacting with or being an integral part of such equipment, the system 100 according to the invention is advantageously able to cause the broadcasting of an image created from data generated by a camera on a portion of each of the screens.
De plus, pour mettre en œuvre certaines étapes du procédé selon l’invention décrit ci-dessous, le système 100 selon l’invention est muni d’éléments matériels (e.g. connectique réseau CAN, Ethernet, etc.) et logiciels dédiés pour interagir avec un sélecteur de vitesse d’un véhicule automobile. Ainsi, grâce à ces moyens, le système 100 selon l’invention est avantageusement en mesure de déterminer si le sélecteur de vitesse du véhicule est enclenché sur la position marche arrière. Selon l’invention, tous les éléments décrits ci-dessus contribuent donc pour permettre au système 100 selon l’invention de mettre en œuvre un procédé de gestion du fonctionnement d’un appareillage de surveillance de l’environnement de conduite du véhicule, tel que décrit ci-dessous en lien avec les figures 2-4. In addition, to implement certain steps of the method according to the invention described below, the system 100 according to the invention is provided with hardware elements (eg CAN network connectors, Ethernet, etc.) and dedicated software for interacting with a gear selector of a motor vehicle. Thus, thanks to these means, the system 100 according to the invention is advantageously able to determine whether the vehicle speed selector is engaged in the reverse position. According to the invention, all the elements described above therefore contribute to enabling the system 100 according to the invention to implement a method for managing the operation of a device for monitoring the driving environment of the vehicle, such as described below in conjunction with Figures 2-4.
Selon une première étape 201, le système 100 selon l’invention détermine si le sélecteur de vitesse du véhicule est enclenché sur la position marche arrière. Pour ce faire, le système 100 selon l’invention interagit préférentiellement avec le sélecteur de vitesse du véhicule pour déterminer la position sur laquelle le sélecteur de vitesse est enclenché. Et, lorsqu’il établit que le sélecteur de vitesse du véhicule est enclenché sur la position marche arrière, le système 100 selon l’invention réalise l’étape suivant du procédé selon l’invention décrite ci-dessous. According to a first step 201, the system 100 according to the invention determines whether the vehicle gear selector is engaged in the reverse position. To do this, the system 100 according to the invention preferentially interacts with the vehicle gear selector to determine the position in which the gear selector is engaged. And, when it establishes that the vehicle gear selector is engaged in the reverse position, the system 100 according to the invention performs the next step of the method according to the invention described below.
Selon une deuxième étape 202, le système 100 selon l’invention provoque la diffusion d’une première image créée à partir de données générées par la première caméra sur une première portion de chacun des écrans, et, simultanément, la diffusion d’une deuxième image créée à partir de données générées par la deuxième caméra sur une deuxième portion de chacun des écrans. De préférence, la première portion occupe la moitié de gauche de chacun des écrans et la deuxième portion occupe la moitié de droite de chacun des écrans (figure 3). Alternativement, la première portion est incrustée au sein de la deuxième portion sur le deuxième écran et la deuxième portion est incrustée au sein de la première portion sur le premier écran (figure 4), la première portion est juxtaposée à la deuxième portion ou la première et/ou la deuxième portion occupe une moitié de chacun des écrans. Ainsi, grâce au procédé et au système selon l’invention décrits ci- dessus, une solution existe pour permettre à un appareillage de surveillance de l’environnement de conduite d’un véhicule automobile d’informer de manière plus ergonomique l’utilisateur lors de manœuvres réalisées en marche arrière. En effet, le procédé et le système selon l’invention contribuent notamment pour, lors de manœuvres réalisées en marche arrière, éviter au conducteur de devoir, de manière successive, renoncer à surveiller l’un ou l’autre des deux côtés du véhicules. Par ce biais, le procédé et le système selon l’invention permettent d’améliorer la sécurité de la conduite. According to a second step 202, the system 100 according to the invention causes the broadcasting of a first image created from data generated by the first camera on a first portion of each of the screens, and, simultaneously, the broadcasting of a second image created from data generated by the second camera on a second portion of each of the screens. Preferably, the first portion occupies the left half of each of the screens and the second portion occupies the right half of each of the screens (FIG. 3). Alternatively, the first portion is embedded within the second portion on the second screen and the second portion is embedded within the first portion on the first screen (FIG. 4), the first portion is juxtaposed with the second portion or the first and/or the second portion occupies half of each of the screens. Thus, thanks to the method and to the system according to the invention described above, a solution exists to allow an apparatus for monitoring the driving environment of a motor vehicle to inform the user in a more ergonomic manner when reverse maneuvers. Indeed, the method and the system according to the invention contribute in particular to, during maneuvers carried out in reverse, preventing the driver from having to successively give up monitoring one or the other of the two sides of the vehicle. By this means, the method and the system according to the invention make it possible to improve driving safety.
