Description

DISPOSITIF DE SIGNALISATION LUMINEUSE POUR AVERTIR ET FAIRE RESPECTER UNE DISTANCE DE SECURITE ENTRE DEUX VEHICULES. LIGHT SIGNALING DEVICE FOR WARNING AND ENFORCEMENT OF A SAFETY DISTANCE BETWEEN TWO VEHICLES.
L'invention est relative à un dispositif de signalisation lumineuse pour avertir et faire respecter une distance de sécurité entre deux véhicules. L'invention est particulièrement utile dans son application à la sécurité routière et plus particulièrement à la prévention des accidents automobiles.The invention relates to a light signaling device for warning and enforcing a safety distance between two vehicles. The invention is particularly useful in its application to road safety and more particularly to the prevention of automobile accidents.
Une des causes d'accidents graves sur route est le non-respect des distances minimales entre chaque véhicule, surtout à grande vitesse. Des essais de mise en garde, par exemple au moyen d'une signalisation sur la chaussée de certaines autoroutes, ont été réalisés. Les résultats sont restés dans ce cas limités à la zone intéressée par la signalisation.One of the causes of serious road accidents is failure to observe the minimum distances between each vehicle, especially at high speed. Warning tests have been carried out, for example by means of road signs on certain motorways. In this case, the results were limited to the area interested in the signaling.
Le conducteur d'un véhicule peut cependant apprécier d'un seul regard dans son ou ses rétroviseurs si la voiture qui le suit respecte bien une distance élémentaire de sauvegarde.The driver of a vehicle can however appreciate with a single glance in his or her mirrors if the car which follows him respects a basic saving distance.
Si la distance entre les deux véhicules est réduite au point de présenter un danger en cas par exemple d'obstacle inattendu ou de freinage brusque ou par simple imprudence involontaire ou non du conducteur du véhicule suivant, le conducteur du premier véhicule n'a aucun moyen de mettre en garde celui qui le suit et de l'inviter à prendre ses distances.If the distance between the two vehicles is reduced to the point of presenting a danger in the event of, for example, an unexpected obstacle or sudden braking or by unintentional or unintentional recklessness of the driver of the following vehicle, the driver of the first vehicle has no to warn those who follow them and invite them to distance themselves.
Pour remédier à cette situation, le document FR 2.546.458 propose d'utiliser un boîtier plat au fond duquel est disposé un groupe d'ampoules, le boîtier étant fermé par une plaque ou matériau transparent par exemple rouge : à l'envers de cette plaque est disposé un cache dans lequel des lettres sont découpées laissant apparaître par exemple le mot «distance » quand les ampoules sont alimentées à partir des «feux de stop » lors d'un début de freinage.To remedy this situation, document FR 2,546,458 proposes using a flat box at the bottom of which is arranged a group of bulbs, the box being closed by a plate or transparent material, for example red: on the back of this plate is placed a cover in which letters are cut revealing for example the word "distance" when the bulbs are powered from the "brake lights" at the start of braking.
Egalement, le document FR 2.606.717 propose un système détecteur d'obstacles à l'arrière des véhicules. Ce système comporte un dispositif de détection et donc de protection déterminant un écran constitué par une surface créée par le balayage soit d'une cellule photoélectrique, soit d'un système de détection infrarouge ou à ultrasons, etc.. Ce système permet au conducteur d'engin faisant une manoeuvre de savoir si un obstacle qu'il risque de heurter se trouve dans un angle aveugle.Also, document FR 2,606,717 proposes an obstacle detection system at the rear of vehicles. This system includes a detection and therefore protection device determining a screen consisting of a surface created by scanning either a photoelectric cell, or an infrared or ultrasonic detection system, etc. This system allows the driver to 'machine making a maneuver to know if an obstacle which it is likely to strike is in a blind angle.
Enfin, le document FR 2.610.433 proposant l'utilisation d'un boîtier électrique permettant de se faire des signaux d'automobiliste à automobiliste, décrit un appareil destiné à lancer des signaux électriques afin de faire savoir de son automobile à un autre automobiliste que l'on aimerait converser avec celui-ci, ce même appareil servant à refuser toute invitation de ce genre.Finally, the document FR 2.610.433 proposing the use of an electrical box making it possible to make signals from motorist to motorist, describes an apparatus intended to launch electrical signals in order to make his automobile known to another motorist whom one would like to converse with this one, this same apparatus being used to refuse any invitation of this kind.
Un but de la présente invention est d'assurer la prévention dans le cadre de la sécurité routière, de conducteurs de véhicules lorsqu'ils se rapprochent dangereusement les uns des autres, sans tenir compte d'une distance de sécurité minimale dont l'inobservation est à l'origine de nombreux accidents mortels.An object of the present invention is to ensure prevention in the context of road safety, of vehicle drivers when they approach dangerously close to each other, without taking into account a minimum safety distance whose non-compliance is the cause of many fatal accidents.

Selon d'autres caractéristiques de l'invention :The subject of the invention is a light signaling device for warning and enforcing a safety distance between two vehicles, of the type comprising a body forming a strip or housing; said body being transparent or translucent on a part intended to be turned towards the rear of a vehicle and containing light emission means connected to an electrical supply, characterized in that the light emission means are predetermined and controlled sequentially for cyclically emitting several light pulses close to a first color and a light pulse of a second color. According to other characteristics of the invention:
- le corps en forme de réglette ou de boîtier est divisé sur sa longueur en six compartiments, les deux compartiments centraux et les deux compartiments extrêmes latéraux sont de taille et de volume sensiblement identiques, et les compartiments intermédiaires sont plus importants en longueur et en volume que les précédents. - la partie transparente ou translucide des deux compartiments centraux est orange, celle des deux compartiments latéraux extrêmes est verte, et celle des compartiments intermédiaires est rouge.- the body in the form of a strip or a box is divided along its length into six compartments, the two central compartments and the two lateral extreme compartments are of substantially identical size and volume, and the intermediate compartments are larger in length and in volume than the previous ones. - the transparent or translucent part of the two central compartments is orange, that of the two extreme lateral compartments is green, and that of the intermediate compartments is red.
- un temporisateur-modulateur logé dans un compartiment intermédiaire répartit entre les ampoules ou navettes des compartiments l'impulsion électrique aussi longtemps qu'est maintenu et agit un contact de mise en fonction.- a timer-modulator housed in an intermediate compartment distributes between the bulbs or shuttles of the compartments the electrical impulse as long as it is maintained and a contact activates.
- la répartition du courant électrique se fait selon trois impulsions brèves rapprochées allumant le moyen d'émission lumineuse d'au moins un compartiment central orange avec un temps d'interruption égal court entre chacune d'elles, suivies d'une seule impulsion allumant le moyen d'émission lumineuse d'au moins un compartiment vert latéral et la durée d'allumage de chaque compartiment vert est égale à celle des trois allumages successifs de chaque compartiment orange. - les moyens d'émission lumineuse sont commandables par le conducteur, par action manuelle ou par action sur une pédale ou analogue.- the distribution of the electric current is done according to three short close pulses lighting the light emission means of at least one orange central compartment with an equal short interruption time between each of them, followed by a single pulse lighting the means of light emission from at least one lateral green compartment and the duration of lighting of each green compartment is equal to that of the three successive ignitions of each orange compartment. - The light emission means are controllable by the driver, by manual action or by action on a pedal or the like.
- les moyens d'émission lumineuse sont éventuellement commandables automatiquement, sans intervention du conducteur, par exemple déclenchés par une cellule de mesure de distance entre deux véhicules.- The light emission means can be controlled automatically, without driver intervention, for example triggered by a distance measuring cell between two vehicles.
- le dispositif comporte un couplage manuel et/ou automatique avec au moins un autre équipement électrique d'un véhicule auquel le dispositif est destiné.- The device comprises a manual and / or automatic coupling with at least one other electrical equipment of a vehicle for which the device is intended.
- le dispositif comporte des moyens de fixation à un véhicule.- The device comprises means for fixing to a vehicle.
- le dispositif est agencé pour être intégré dans la ligne arrière du véhicule. De préférence, un dispositif selon l'invention comporte une réglette de dimensions ajustables en longueur, hauteur et profondeur, de section par exemple parallélépipédique, sphérique, hémisphérique, elliptique, rectangulaire, triangulaire, losangique, trapézoïdale ou polygonale, dont la partie orientée vers l' arrière du véhicule est transparente ou translucide, adaptable suivant la taille de la lunette arrière, du hayon ou du coffre du véhicule. Une telle réglette est par exemple réalisée en matériau dur ou semi-rigide ou souplement une extrémité de cette réglette peut présenter une lumière, une échancrure pour le passage des fils d'alimentation en énergie électrique et des fils de commande pour la mise en marche et l'arrêt.- The device is arranged to be integrated into the rear line of the vehicle. Preferably, a device according to the invention comprises a strip of dimensions adjustable in length, height and depth, of section for example parallelepipedic, spherical, hemispherical, elliptical, rectangular, triangular, lozenge-shaped, trapezoidal or polygonal, the part of which faces towards the The rear of the vehicle is transparent or translucent, adaptable according to the size of the rear window, the tailgate or the trunk of the vehicle. Such a strip is for example made of hard or semi-rigid material or flexibly one end of this strip may have a lumen, a notch for the passage of the electrical power supply wires and the control wires for switching on and the stop.
L'emplacement et la fixation de la réglette peut se faire soit à l'intérieur du véhicule sur la face interne de la lunette arrière à l'aide de ventouses simples ou de pompes à vide, ou sur la plage arrière par le biais d'une ou plusieurs potences ou bras, articulés ou non, prolongés ou non par des ventouses ou des pompes à vide.The location and fixing of the strip can be done either inside the vehicle on the internal face of the rear window using simple suction cups or vacuum pumps, or on the rear shelf by means of one or more brackets or arms, articulated or not, extended or not by suction cups or vacuum pumps.
La réglette, avec ses potences sur lesquelles elle reste orientable, peut être bloquée en position sur les potences par une vis papillon, ou fixée par un adhésif simple ou bi-face ou « Velcro » (marque déposée), éventuellement à l'extérieur du véhicule sur le hayon ou la malle arrière par ventousage, sanglage, adhésif, aimantage, vissage ou rivetage.The strip, with its brackets on which it remains orientable, can be locked in position on the brackets by a butterfly screw, or fixed by a simple or two-sided adhesive or "Velcro" (registered trademark), possibly outside the vehicle on the tailgate or the trunk by suction, strapping, adhesive, magnet, screwing or riveting.
Enfin, pour les véhicules neufs à venir des constructeurs, l'intégration du dispositif dans la carrosserie du hayon, de la malle arrière ou de la jupe arrière d'un véhicule neuf permet la réalisation simultanée du dispositif et du véhicule correspondant. L'invention sera mieux comprise grâce à la description qui va suivre donnée à titre d'exemple non limitatif en référence aux dessins annexés dans lesquels :Finally, for new vehicles to come from manufacturers, the integration of the device into the body of the tailgate, the trunk or the rear skirt of a new vehicle allows the device and the corresponding vehicle to be produced simultaneously.

Selon l'invention, le dispositif est agencé pour émettre cycliquement plusieurs impulsions lumineuses rapprochées d'une première couleur et une impulsion lumineuse d'une deuxième couleur. A cet effet, on peut prévoir que la paroi tournée vers l'arrière du dispositif présente des couleurs différentes sur chaque compartiment : la paroi extérieure transparente ou translucide des deux compartiments centraux 2a, 2b est par exemple de couleur orange ; la paroi extérieure transparente ou translucide des deux compartiments intermédiaires 3 a, 3 b est par exemple de couleur rouge ; la paroi extérieure transparente ou translucide des compartiments extérieurs 4a, 4b est par exemple de couleur verte.According to the invention, the device is arranged to cyclically emit several light pulses close to a first color and a light pulse of a second color. To this end, provision may be made for the wall facing the rear of the device to have different colors on each compartment: the transparent or translucent outer wall of the two central compartments 2a, 2b is for example of Orange color ; the transparent or translucent outer wall of the two intermediate compartments 3 a, 3 b is for example of red color; the transparent or translucent outer wall of the outer compartments 4a, 4b is for example of green color.
Lors de l'émission lumineuse, la face tournée vers l'arrière du véhicule de chacun des quatre compartiments centraux ou extérieurs 2a, 2b ou 4a, 4b, fait apparaître de préférence le dessin schématisé d'une voiture automobile : cet affichage de voiture automobile peut être effectué à plat, en relief, au moyen d'un cache intérieur ou par tout autre moyen.During the light emission, the side facing the rear of the vehicle from each of the four central or external compartments 2a, 2b or 4a, 4b, preferably shows the diagrammatic drawing of a motor car: this motor car display can be carried out flat, in relief, by means of an internal cover or by any other means.
L'énergie électrique nécessaire pour l'émission lumineuse est fournie, soit de manière autonome par les piles électriques 6 ou batteries rechargeables, soit directement par la batterie 11 du véhicule, par exemple par branchement sur l' allume-cigares ou autre prise électrique analogue.The electrical energy necessary for the light emission is supplied either autonomously by the electric batteries 6 or rechargeable batteries, or directly by the battery 11 of the vehicle, for example by connection to the cigarette lighter or other similar electrical outlet. .
Bien entendu, dans le cas de véhicules neufs fabriqués simultanément dès l'origine avec le dispositif selon l'invention, la fourniture d'énergie électrique pourra faire partie de l'équipement d'origine du véhicule. Le déclenchement du dispositif selon l'invention peut s'effectuer par une commande manuelle 12 ou une commande au pied similaire, par exemple une pédale. Pour les véhicules neufs de constructeurs, un mode préféré de réalisation de l'invention consiste à réaliser la commande du dispositif à partir d'un «Comodo » (marque déposée) disposé à demeure au voisinage du volant de direction. Pour solidariser le dispositif selon l'invention à un véhicule, dans une position correspondant à l'émission vers l'arrière des impulsions lumineuses de couleurs, on utilise par exemple des potences 14 montées à demeure sur le véhicule, par rapport auquel le dispositif selon l'invention peut être orienté au moyen d'une vis papillon.Of course, in the case of new vehicles manufactured simultaneously from the outset with the device according to the invention, the supply of electrical energy may be part of the original equipment of the vehicle. The device according to the invention can be triggered by a manual control 12 or a similar foot control, for example a pedal. For new manufacturers' vehicles, a preferred embodiment of the invention consists in controlling the device from a “Comodo” (registered trademark) permanently installed in the vicinity of the steering wheel. To secure the device according to the invention to a vehicle, in a position corresponding to the emission towards the rear of the light pulses of colors, use is made for example of brackets 14 permanently mounted on the vehicle, relative to which the device according to the invention can be oriented by means of a butterfly screw.
Cette variante de réalisation est particulièrement applicable à la fixation d'un dispositif selon l'invention sur une plage arrière de véhicule.This variant embodiment is particularly applicable to the fixing of a device according to the invention on a rear platform of the vehicle.
Sur la figure 2, un autre mode de réalisation de dispositif selon l'invention comporte des éléments identiques ou similaires à ceux de la figure 1 et repérés par des chiffres de références identiques à ceux de la figure 1.In FIG. 2, another embodiment of the device according to the invention comprises elements identical or similar to those of FIG. 1 and identified by reference numbers identical to those of FIG. 1.
Les parois extérieures 22a, 22b, 23a, 23b, 24a, 24b respectives des compartiments 2a, 2b, 3a, 3b, 4a, 4b présentent des couleurs différentes, de manière que le dispositif émette cycliquement plusieurs impulsions lumineuses rapprochées d'une première couleur et une impulsion lumineuse d'une deuxième couleur.The respective external walls 22a, 22b, 23a, 23b, 24a, 24b of the compartments 2a, 2b, 3a, 3b, 4a, 4b have different colors, so that the device emits cyclically several light pulses close to a first color and a light pulse of a second color.
Le dispositif peut être fixé dans cet exemple au moyen de ventouses 25a, 25b ou pompes à vide analogues directement sur une surface plane ou inclinée du véhicule. Sur les figures 3 et 4, des éléments identiques ou fonctionnellement équivalents à ceux des figures 1 et 2 sont repérés par des chiffres de référence identiques.The device can be fixed in this example by means of suction cups 25a, 25b or similar vacuum pumps directly on a flat or inclined surface of the vehicle. In FIGS. 3 and 4, elements which are identical or functionally equivalent to those in FIGS. 1 and 2 are identified by identical reference numbers.
Le dispositif de la figure 3 destiné à être fixé à l'arrière d'un véhicule comporte des compartiments 30a, 30b abritant respectivement des boîtiers 5 simples et 7 doubles.The device of FIG. 3 intended to be fixed to the rear of a vehicle comprises compartments 30a, 30b respectively housing single and 7 double housings.
Le compartiment 7 double comporte un moyen de détection de distance 8 visible par l' arrière du véhicule .The double compartment 7 comprises a distance detection means 8 visible from the rear of the vehicle.
La paroi des compartiments intermédiaires 30a, 30b ne présente pas de couleur particulière et est opaque dans l'exemple représenté. Cependant, l'émission lumineuse de couleur rouge est assurée par un feu déclenché lors du freinage appelé couramment «feu stop » : ce feu 31 s'étend de préférence sur toute la longueur des compartiments centraux et des compartiments intermédiaires.The wall of the intermediate compartments 30a, 30b has no particular color and is opaque in the example shown. However, the red light emission is ensured by a light triggered during braking commonly called "stop light": this light 31 preferably extends over the entire length of the central compartments and of the intermediate compartments.
Sur la figure 3, le troisième mode de réalisation du dispositif selon l'invention se présente de manière autonome et est destiné à être fixé à un véhicule, tandis que sur la figure 4, le dispositif selon l'invention est destiné à être intégré dans un véhicule neuf fabriqué par un constructeur. Dans les modes de réalisation représentés, le fonctionnement des dispositifs selon l'invention est de préférence le suivant :In FIG. 3, the third embodiment of the device according to the invention is presented independently and is intended to be fixed to a vehicle, while in FIG. 4, the device according to the invention is intended to be integrated in a new vehicle manufactured by a manufacturer. In the embodiments shown, the operation of the devices according to the invention is preferably as follows:
Le temporisateur-modulateur 9 intégré dans un boîtier double, tel que le boîtier 7 du compartiment 3b répartit les impulsions électriques de la manière suivante aussi longtemps qu'une alimentation électrique est fournie : trois impulsions égales rapprochées allument des ampoules des compartiments centraux pour émettre trois impulsions de couleur orange avec un temps d'interruption sensiblement égal et relativement court entre chaque impulsion successive. Ce train de trois impulsions égales rapprochées est ensuite suivi d'une impulsion unique allumant les ampoules des compartiments verts latéraux extrêmes, et ce pendant une durée égale à la durée totale du train des trois premières impulsions, de manière à produire un effet d'avertissement analogue à celui produit par les éclats puis le feu d'un phare marin ou d'un stroboscope. Dans l'application des dispositifs des figures 3 et 4, l'utilisation plus élaborée du dispositif selon l'invention consiste à utiliser le troisième feu stop, c'est-à-dire le signal de freinage pour fournir une bande lumineuse rouge qui ne forme qu'un seul élément et occupe la largeur des compartiments intermédiaires jouxtant les compartiments centraux. De manière avantageuse, la partie frontale extérieure transparente ou translucide des deux compartiments intermédiaires peut également être de couleur rouge sans représentation d'un véhicule automobile.The timer-modulator 9 integrated in a double housing, such as the housing 7 of compartment 3b distributes the electrical pulses in the following manner as long as an electrical supply is supplied: three equal pulses close together light up bulbs in the central compartments to emit three orange-colored pulses with a substantially equal and relatively short interruption time between each successive pulse. This train of three equal pulses close together is then followed by a single pulse lighting the bulbs of the extreme lateral green compartments, for a duration equal to the total duration of the train of the first three pulses, so as to produce a warning effect analogous to that produced by the splinters then the fire of a marine lighthouse or a strobe. In the application of the devices of FIGS. 3 and 4, the more elaborate use of the device according to the invention consists in using the third brake light, that is to say the braking signal to provide a red light strip which does not forms a single element and occupies the width of the intermediate compartments adjoining the central compartments. Advantageously, the transparent or translucent external front part of the two intermediate compartments can also be red without the representation of a motor vehicle.
Dans un premier mode d'utilisation simple, le dispositif selon l'invention est déclenché, en résultat d'une intervention volontaire du conducteur agissant sur un moyen manuel 12 ou une pédale : cette commande est par conséquent liée à l'appréciation des distances par le conducteur.In a first simple mode of use, the device according to the invention is triggered, as a result of a voluntary intervention by the driver acting on a manual means 12 or a pedal: this command is therefore linked to the appreciation of the distances by the driver.
Dans un mode d'utilisation plus élaboré, le dispositif selon l'invention est commandé automatiquement par le déclenchement d'une cellule de mesure de distance 8 placée dans un boîtier de compartiment intermédiaire ou d'une autre cellule ou moyen de mesure de distance émettant vers l'arrière un rayonnement ou une émission, par exemple une émission de rayons infrarouge, ou d'ultrasons ; ou alternativement, la mesure peut impliquer un moyen de thermo-détection.In a more elaborate mode of use, the device according to the invention is automatically controlled by the triggering of a distance measuring cell 8 placed in an intermediate compartment housing or of another cell or distance measuring means emitting towards the rear a radiation or an emission, for example an emission of infrared rays, or of ultrasound; or alternatively, the measurement may involve a means of thermal detection.
Dans ce cas la distance minimale qui déclenche un avertissement entre deux véhicules peut être prédéterminée et réglée à l'avance. Par exemple, cette distance peut être modifiée et choisie par le conducteur avant la mise en route du véhicule en faisant varier un angle d'inclinaison d'un axe de mesure d'une cellule 8 ou analogue au moyen d'une vis de réglage située à proximité ou à l'arrière d'un boîtier contenant cette cellule de mesure, de manière à incliner plus ou moins la cellule articulée dans sa partie antérieure avec une base de réglette ou de boîtier. L'utilisation d'un mode de fonctionnement automatique est particulièrement avantageux en cas de visibilité réduite : L'invention s'étend par conséquent également au cas d'une double commande manuelle et automatique, le conducteur pouvant passer à sa guise de la position de commande manuelle à la position de commande automatique et inversement à partir d'un boîtier de commande placé sur le tableau de bord ou d'un « Comodo » (marque déposée) sous le volant. Lors d'une circulation en centre ville, ou dans un endroit chargé en véhicules circulant à faible vitesse, il est possible de neutraliser la cellule de mesure pour éviter le déclenchement d'avertissement intempestif. Le dispositif selon l'invention fournit ainsi un signal spécifique de mise en garde et de prévention, au moyen d'un procédé de mise en œuvre aisé, ceci permettant d'envisager une diffusion pouvant aboutir à la reconnaissance et à l'établissement de normes nouvelles et universelles de prévention et de sécurité routière. Selon un perfectionnement non écrit de la présente invention, il est envisageable d'incorporer dans le bloc optique arrière gauche ou droit des véhicules un moyen d'émission de signal lumineux de couleur spécifique non utilisée jusqu'à présent (par exemple de couleurs violette), de manière à permettre au conducteur d'une voiture suivie par un autre véhicule de déclencher un signal au coup par coup ou de mettre le dispositif en mode automatique selon le processus décrit plus haut.In this case, the minimum distance that triggers a warning between two vehicles can be predetermined and adjusted in advance. For example, this distance can be modified and chosen by the driver before the vehicle is started by varying a tilt angle of a measurement axis of a cell 8 or the like by means of an adjustment screw located near or behind a box containing this measuring cell, so as to tilt the articulated cell more or less in its front part with a strip or box base. The use of an automatic operating mode is particularly advantageous in the event of reduced visibility: The invention therefore also extends to the case of a manual and automatic double control, the driver being able to switch as desired from the position of manual control to the automatic control position and vice versa from a control unit placed on the dashboard or from a “Comodo” (registered trademark) under the steering wheel. When driving in the city center, or in a place loaded with vehicles traveling at low speed, it is possible to deactivate the measuring cell to prevent the nuisance warning being triggered. The device according to the invention thus provides a specific warning and prevention signal, by means of an easy implementation method, this making it possible to envisage a dissemination which may result in the recognition and establishment of standards. and universal news on road safety and prevention. According to an unwritten improvement of the present invention, it is conceivable to incorporate in the left or right rear optical unit of the vehicles a light signal emission means of specific color not used until now (for example purple colors) , so as to allow the driver of a car followed by another vehicle to trigger a piecemeal signal or to put the device in automatic mode according to the process described above.
Selon un autre perfectionnement de l'invention, le dispositif peut comprendre un couplage automatique avec une mise en action des phares antibrouillard d'un véhicule.According to another improvement of the invention, the device can comprise an automatic coupling with an activation of the fog lights of a vehicle.
Dans le cadre de l'installation sur les véhicules futurs fabriqués directement par le constructeur, le dispositif selon l'invention peut être réalisé de manière simplifiée en ne gardant qu'une ligne horizontale relativement mince de feux vert, rouge, orange, orange, rouge et vert, ne présentant pas obligatoirement des schémas de voitures, mais étant conçu pour être intégré dans la ligne arrière d'un véhicule. L'essentiel est selon l'invention que le dispositif fonctionne comme décrit en produisant trois impulsions lumineuses rapprochées d'une première couleur suivies de une ou plusieurs impulsions lumineuses d'une autre couleur et d'une durée totale égale au train précité des trois premières impulsions lumineuses de première couleur.As part of the installation on future vehicles manufactured directly by the manufacturer, the device according to the invention can be produced in a simplified manner by keeping only a relatively thin horizontal line of green, red, orange, orange, red lights. and green, not necessarily showing car diagrams, but being designed to be integrated into the rear line of a vehicle. The essential is according to the invention that the device operates as described by producing three light pulses close to a first color followed by one or more light pulses of another color and of a total duration equal to the above-mentioned train of the first three first color light pulses.
En outre, sans sortir du cadre de la présente invention, le moyen de mesure de distance ou de détection telle qu'une cellule photoélectrique, une cellule infrarouge, une cellule à ultrasons, ou un moyen de thermo-détection, ainsi que le temporisateur-modulateur peuvent être placés dans la partie intérieure d'un hayon ou d'un coffre arrière d'un véhicule, en étant séparés du corps du dispositif proprement dit auxquels ils sont reliés par des liaisons filaires appropriées, ou un moyen équivalent du genre liaison centralisée ou multiplexée.In addition, without departing from the scope of the present invention, the distance measuring or detection means such as a photoelectric cell, an infrared cell, an ultrasonic cell or a thermo-detection means, as well as the timer- modulator can be placed in the interior part of a tailgate or a trunk of a vehicle, being separated from the body of the device proper to which they are connected by appropriate wire connections, or an equivalent means of the kind centralized connection or multiplexed.
L'invention permet ainsi dans les variantes décrites à titre d'exemple non limitatif d'être exploitée industriellement soit par l'inventeur pour les produits adaptables aux véhicules existants, soit par des équipementiers ou des constructeurs automobiles aussi bien pour les produits adaptables aux véhicules existants que pour des véhicules neufs. The invention thus makes it possible, in the variants described by way of nonlimiting example, to be exploited industrially either by the inventor for products adaptable to existing vehicles, or by equipment manufacturers or automobile manufacturers as well as for products adaptable to vehicles existing only for new vehicles.
