Description

SYSTEME D'AIDE A LA CONDUITE D'UN VEHICULE AUTOMOBILE  DRIVER ASSISTANCE SYSTEM FOR A MOTOR VEHICLE
La présente invention concerne les systèmes d'aide à la conduite pour véhicules automobiles et concerne plus particulièrement un système permettant de sécuriser les abords latéraux d'un véhicule automobile quand les feux de détresse du véhicule, communément désignés par le terme anglo-saxon « warning », sont allumés. The present invention relates to driving assistance systems for motor vehicles and more particularly relates to a system for securing the lateral approaches of a motor vehicle when the vehicle hazard warning lights, commonly referred to by the English word "warning". Are on.
Dans une situation classique de circulation sur route ouverte, quand le conducteur d'un véhicule doit arrêter d'urgence son véhicule et/ou le garer sur une zone non prévue pour le stationnement, l'usage habituel est que le conducteur du véhicule active manuellement les feux de détresse pour prévenir les autres véhicules qui sont dans son environnement proche, et notamment dans son sillage, d'un risque potentiel voire réel.  In a conventional open road situation, when the driver of a vehicle must urgently stop his vehicle and / or park it on an area not intended for parking, the usual practice is for the driver of the vehicle to activate manually warning lights to prevent other vehicles that are in its immediate environment, and in particular in its wake, a potential or even real risk.
Dès qu'un véhicule automobile est arrêté sur une zone normalement interdite au stationnement ou limitée aux cas d'urgence comme les bandes d'arrêt d'urgence sur les voies rapides, il est reconnu que le danger est maximal au moment où les passagers sortent du véhicule pour se placer derrière les barrières de sécurité comme cela est recommandé par les organismes de prévention des accidents de circulation. Ce danger est surtout maximal pour les passagers situés du côté de la voie de circulation lorsque ces derniers sortent du véhicule.  As soon as a motor vehicle is stopped in an area normally prohibited from parking or limited to emergency situations such as emergency lanes on expressways, it is recognized that the danger is greatest at the moment passengers leave the scene. the vehicle to stand behind the safety gates as recommended by traffic accident prevention organizations. This danger is greatest for passengers on the side of the taxiway when they leave the vehicle.
Actuellement, les systèmes d'alarme et d'alerte de danger (Warning), réalisés principalement par les feux avant et arrière du véhicule en mode de clignotement simultané, ne servent qu'à alerter les autres véhicules de la présence d'un danger ou d'un problème sur le véhicule.  At present, Warning and Warning Systems, mainly carried out by the front and rear lights of the vehicle in simultaneous flashing mode, only serve to alert other vehicles to the presence of a hazard or a problem on the vehicle.
Ces systèmes ne permettent pas de sécuriser en plus, les abords latéraux du véhicule en délimitant visuellement un périmètre de sécurité autour du véhicule.  These systems do not make it possible to secure, moreover, the lateral approaches of the vehicle by visually delimiting a perimeter of security around the vehicle.
La présente invention a notamment pour but d'apporter une solution simple et peu coûteuse permettant de sécuriser les occupants du véhicule au moment où ces derniers sortent du véhicule et de diminuer ainsi les risques d'accident. The present invention aims in particular to provide a simple and inexpensive solution for securing the occupants of the vehicle to when they leave the vehicle and thus reduce the risk of accidents.
Elle propose à cet effet, un système d'aide à la conduite pour un véhicule automobile équipé de feux de détresse, caractérisé en ce qu'il comporte en outre au moins un dispositif de projection d'images disposé sur le bas de caisse du véhicule, à proximité du tour de roue d'une roue avant du véhicule et apte à projeter sur le sol, dans un espace correspondant à un abord latéral du véhicule, une zone de sécurité pour les occupants du véhicule quand ce dernier est en situation de danger signalée par l'allumage des feux de détresse du véhicule.  It proposes for this purpose, a driving assistance system for a motor vehicle equipped with hazard warning lights, characterized in that it further comprises at least one image projection device disposed on the underside of the vehicle , near the wheel turn of a front wheel of the vehicle and capable of projecting on the ground, in a space corresponding to a lateral approach of the vehicle, a safety zone for the occupants of the vehicle when the latter is in a dangerous situation signaled by the ignition of the vehicle's hazard warning lights.
Selon une caractéristique, la zone de sécurité définit un « tapis de lumière » sur le sol de largeur et longueur déterminées par les dimensions du véhicule.  According to one characteristic, the safety zone defines a "carpet of light" on the floor of width and length determined by the dimensions of the vehicle.
Selon une autre caractéristique, la zone de sécurité s'étend de la porte avant du véhicule vers l'arrière du véhicule et est visible à distance par d'autres véhicules.  According to another characteristic, the safety zone extends from the front door of the vehicle towards the rear of the vehicle and is visible remotely by other vehicles.
Selon une autre caractéristique, la zone de sécurité affiche des informations de signalisation fixes ou animées compréhensibles pour les occupants du véhicule.  According to another characteristic, the security zone displays fixed or animated signaling information comprehensible for the occupants of the vehicle.
Selon une autre caractéristique, les informations sont aptes à inciter les occupants à sortir du véhicule suivant une direction déterminée.  According to another characteristic, the information is able to encourage the occupants to exit the vehicle in a given direction.
Selon une autre caractéristique, le dispositif de projection d'images projette les images sur le sol à l'ouverture d'au moins une porte du véhicule.  According to another characteristic, the image projection device projects the images on the ground at the opening of at least one door of the vehicle.
Dans une variante, le système selon l'invention comporte deux dispositifs de projection d'images disposés symétriquement par rapport à l'axe longitudinal du véhicule pour être aptes à projeter sur le sol, respectivement deux zones de sécurité de part et d'autre du véhicule.  In a variant, the system according to the invention comprises two image projection devices arranged symmetrically with respect to the longitudinal axis of the vehicle to be able to project on the ground respectively two safety zones on either side of the vehicle. vehicle.
L'invention a également pour objet, un véhicule automobile comportant un système d'aide à la conduite tel que décrit ci-dessus. La présente invention permet de réduire l'accidentologie des piétons sur les voies de circulation rapides en rajoutant une couche sécuritaire aux systèmes d'alarme et d'alerte de danger (Warning) existants. The invention also relates to a motor vehicle comprising a driving assistance system as described above. The present invention makes it possible to reduce pedestrian accidentology on fast traffic lanes by adding a layer that is safe to existing alarm and warning systems.
L'invention sera mieux comprise et d'autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d'exemple, en référence aux dessins annexés dans lesquels les figures illustrent un système d'aide à la conduite selon l'invention, et notamment :  The invention will be better understood and other features and advantages will appear more clearly on reading the following description given by way of example, with reference to the accompanying drawings in which the figures illustrate a driving assistance system. according to the invention, and in particular:
- La figure 1 illustre selon une vue de côté, un véhicule muni d'un système d'aide à la conduite selon l'invention délimitant une zone de protection sur un des bords latéraux du véhicule ; et  - Figure 1 illustrates in a side view, a vehicle with a driving aid system according to the invention defining a protection zone on one of the lateral edges of the vehicle; and
- La figure 2 illustre selon une vue de dessus, le véhicule muni du système d'aide à la conduite selon l'invention délimitant un périmètre visuel de sécurité de part et d'autre des bords latéraux du véhicule. La figure 1 illustre une vue du côté gauche d'un véhicule automobile 1 sur laquelle on distingue la porte avant gauche 2 correspondant à la porte du conducteur et la porte arrière gauche 3.  - Figure 2 illustrates in a view from above, the vehicle provided with the driving assistance system according to the invention defining a visual perimeter security on either side of the side edges of the vehicle. FIG. 1 shows a view on the left side of a motor vehicle 1 on which can be distinguished the front left door 2 corresponding to the driver's door and the left rear door 3.
De façon similaire, du côté droit du véhicule 1 , on distingue (Fig. 2), la porte avant droite 2' (porte passager avant) et la porte arrière droite 3' (porte passager arrière).  Similarly, on the right side of the vehicle 1, there is a distinction (Fig. 2), the right front door 2 '(front passenger door) and the right rear door 3' (rear passenger door).
Dans l'exemple illustré à la figure 1 , un dispositif de projection 7 est disposé sur la partie avant du bas de caisse 4 à proximité du passage de roue 5 de la roue avant 6. Le dispositif de projection 7comporte de manière connue, une ou plusieurs sources de lumière à base de LED, une ou plusieurs LEDs (diodes électroluminescentes), associées à une ou plusieurs lentilles de projection (matrice de microlentilles). Il est capable de projeter une image sur le sol de part et d'autre des bords latéraux du véhicule 1 .  In the example illustrated in FIG. 1, a projection device 7 is disposed on the front part of the underbody 4 near the wheel arch 5 of the front wheel 6. The projection device 7 comprises, in a known manner, one or a plurality of LED-based light sources, one or more LEDs (light-emitting diodes), associated with one or more projection lenses (microlens array). It is able to project an image on the ground on both sides of the side edges of the vehicle 1.
L'image projetée sur le sol est dimensionnée de manière à couvrir au moins une zone 8, s'étendant entre la porte avant 2 et la porte arrière 3 du véhicule 1 de manière à créer une distribution lumineuse appelé également « tapis de lumière » avec un ou des motifs, fixes ou animés, au choix du conducteur ou définis de base par le constructeur du véhicule. The projected image on the ground is dimensioned so as to cover at least one zone 8, extending between the front door 2 and the rear door 3 of the vehicle 1 so as to create a light distribution also called "Carpet of light" with one or more motifs, fixed or animated, at the choice of the driver or defined by the vehicle manufacturer.
Une image identique est projetée de la même manière sur le côté droit du véhicule 1 (Fig. 2) symétriquement par rapport à l'axe longitudinal XX' du véhicule. Les références numériques restent les mêmes en étant suivies d'un « '».  An identical image is projected in the same way on the right side of the vehicle 1 (Fig. 2) symmetrically with respect to the longitudinal axis XX 'of the vehicle. The numerical references remain the same followed by a "'".
Les motifs peuvent prendre différentes formes : bandes lumineuses parallèles, fixes ou clignotantes, répartition de points lumineux de densité et/ou intensité fixe ou variable avec atténuation progressive (effet « dimming »), etc., ou supportant des motifs du type texte, logo, pictogrammes, une combinaison des différentes formes, etc.  The patterns can take different forms: parallel, fixed or flashing light bands, distribution of luminous points of density and / or fixed or variable intensity with progressive attenuation (dimming effect), etc., or supporting patterns of the text, logo type , pictograms, a combination of different forms, etc.
Un tel « tapis de lumière » 8, 8' outre l'aspect esthétique visuel qu'il procure, (animation visuelle) permet d'éclairer de nuit, dans des environnements sans ou à faible éclairage urbain, sur des sols parfois irréguliers, les abords latéraux du véhicule 1 .  Such a "carpet of light" 8, 8 'besides the visual aesthetic aspect that it provides, (visual animation) makes it possible to illuminate at night, in environments without or with low urban lighting, on sometimes irregular soils, sideways of the vehicle 1.
La présente invention exploite avantageusement un tel « tapis de lumière » 8, 8' en cas d'allumage des feux de détresse 9 du véhicule 1 , pour éclairer et délimiter des zones pour sécuriser les abords latéraux du véhicule The present invention advantageously exploits such a "carpet of light" 8, 8 'in case of ignition of the hazard warning lights 9 of the vehicle 1, to illuminate and delimit zones to secure the lateral approaches of the vehicle
1 , protégeant ainsi la sortie des occupants du véhicule 1 en situation de danger, mais ce « tapis de lumière » 8, 8' ne substitue jamais à la signalisation d'un danger comme l'allumage des feux de détresse 9 mais au contraire, rajoute une couche sécuritaire supplémentaire à celle de l'allumage des feux de détresse 9. 1, thus protecting the exit of the occupants of the vehicle 1 in a situation of danger, but this "carpet of light" 8, 8 'never substitutes for the signaling of a danger such as the ignition of the hazard warning lights 9 but on the contrary, adds an additional layer of security to that of the ignition of the hazard warning lights 9.
La largeur du « tapis » 8, 8' est déterminée pour correspondre au minimum à la largeur de débattement maximal d'ouverture des portes et sa longueur est déterminée pour couvrir des zones s'étendant des portes avant The width of the "carpet" 8, 8 'is determined to correspond at least to the width of the maximum opening clearance of the doors and its length is determined to cover areas extending from the front doors
2, 2' du véhicule 1 jusqu'à l'arrière du véhicule 1 de manière à délimiter un périmètre de sécurité suffisant pour que les occupants du véhicule 1 puissent sortir puis s'éloigner du véhicule 1 en toute sécurité, en voyant où ils mettent les pieds et même en les orientant vers une zone de sécurité par exemple par un fléchage lumineux défilant, tout en étant vus des autres véhicules. 2, 2 'of the vehicle 1 to the rear of the vehicle 1 so as to define a safety perimeter sufficient for the occupants of the vehicle 1 to exit and then move away from the vehicle 1 safely, seeing where they put the feet and even pointing them towards a safety zone by example by a flashing light arrows, while being seen other vehicles.
Le faisceau de lumière projeté au sol pour créer le « tapis de lumière » 8, 8' forme un angle déterminé par rapport au bas de caisse 4.  The beam of light projected on the ground to create the "carpet of light" 8, 8 'forms a determined angle relative to the rocker 4.
Ce faisceau est donc visible de loin pour les autres véhicules, et signale que le véhicule 1 est arrêté, ce que n'indique pas forcément les feux de détresse 9 qui peuvent être allumés alors même que le véhicule roule. Cette information visuelle supplémentaire permet d'indiquer aux automobilistes en approche du véhicule 1 , que le véhicule 1 est arrêté et d'une sortie potentielle de ses occupants. Cette information leur permet ainsi d'estimer l'espace de sécurité à respecter en fonction de l'étendue du « tapis de lumière » 8, 8', étendue qui se précisera de plus en plus en fonction du degré d'approche.  This beam is visible from afar for other vehicles, and indicates that the vehicle 1 is stopped, which does not necessarily indicate the hazard warning lights 9 which can be lit even as the vehicle is driving. This additional visual information makes it possible to indicate to the motorists approaching the vehicle 1, that the vehicle 1 is stopped and a potential output of its occupants. This information allows them to estimate the safety space to be respected according to the extent of the "carpet of light" 8, 8 ', which will be more and more determined according to the degree of approach.
La projection peut être activée dès que le conducteur du véhicule 1 active les feux de détresse 9 par appui sur le bouton d'activation des feux de détresse présent dans le poste de conduite du véhicule, ou dès que les feux de détresse 9 sont activés automatiquement à la suite d'un freinage d'urgence.  The projection can be activated as soon as the driver of the vehicle 1 activates the hazard warning lights 9 by pressing the hazard warning button that is present in the driving position of the vehicle, or as soon as the hazard warning lights 9 are activated automatically. following an emergency stop.
A titre de variante, la projection est activée seulement au moment de l'ouverture d'une des portières du véhicule 1 et quand deux projecteurs sont installés symétriquement à l'axe longitudinal XX', seul le projecteur du côté de la portière ouverte sera activé et donc une seule zone de projection donc une seule zone latérale de sécurité sera éclairée du côté de la portière ouverte.  Alternatively, the projection is activated only at the moment of opening one of the doors of the vehicle 1 and when two projectors are installed symmetrically to the longitudinal axis XX ', only the projector on the side of the open door will be activated and therefore only one projection zone and therefore only one safety side zone will be illuminated on the side of the open door.
La projection au sol peut être clignotante avec une fréquence de clignotement identique à celle des feux de détresse 9 et avec une couleur similaire à celle des feux de détresse, typiquement de couleur orange.  The ground projection may be flashing with a flash frequency identical to that of the hazard warning lights 9 and with a color similar to that of the hazard warning lights, typically orange.
Une telle couleur est visible de jour comme de nuit.  Such a color is visible day and night.
