Abstract

The device detects a rapid or slow deceleration of a moving object, particularly a vehicle, and distinguishes between them. The device has two complementary functions: the first is to actuate the brake lights in the event of slow deceleration and the second is to actuate a flashing light in the event of rapid or abrupt deceleration. During slow deceleration, the pulse 11 brings on the lamp 5 by means of 4. The device 10 is used to actuate the brake lights 9. When fulfilling the second function, the device 10 consists of a deceleration sensor 1 connected to a timer 2 and then to a flasher unit 3 which acts on the control circuit 4 and causes the lamp 5 to flash when there is rapid deceleration. The leads 7, 8, 11 provide for the power supply and control of the device 10. The device 10 according to the invention is particularly intended to reduce the number of traffic accidents. The pedal 6 and the lamp 9 do not form part of the invention.

Description

La présente invention a pour objet un dispositif optique ou lumineux permettant d'apprécier et de ditinguer un ralentissement important d'un ralentissement faible d'objet en mouvement et notamment d'un véhicule automobile. The subject of the present invention is an optical or light device making it possible to appreciate and tell a significant slowdown of a weak slowdown of a moving object and in particular of a motor vehicle.

Chaque véhicule automobile est équipé (en application de la loi) à l'arrière de feux "Stop" dont la position en hauteur est inférieure à un mètre par rapport au sol. Dès que le conducteur d'un véhicule appuie sur la pédale de frein, les feux "Stop" (9) s'allument, quelquesoit la puissance du ralentissement, principe du tout ou rien. Ceci a pour but d'avertir les conducteurs des véhicules qui suivent afin qu'ils puissent conserver les distances de sécurité et éviter ainsi des accidents. Each motor vehicle is fitted (in application of the law) at the rear with "Stop" lights, the height position of which is less than one meter from the ground. As soon as the driver of a vehicle presses the brake pedal, the "Stop" lights (9) come on, regardless of the power of the deceleration, the all or nothing principle. The purpose of this is to warn the drivers of the following vehicles so that they can keep the safety distances and thus avoid accidents.

Lors d'un ralentissement important, ou brutal de la circula tion, il faut entre capable de remplir simultanément et très rapidement les deux fonctions suivantes
IO) Voir s'allumer les feux "Stop" des véhicules. En période
de circulation dense, seuls les feux du véhicule qui pré
cède sont visibles ; mais pour les autres, il faut se dé
placer sur les extrémités gauche ou droite du couloir du
sens de la circulation, et malgré cela, les feux '1Stop"
ne sont pas toujours visibles.During a significant, or sudden, slowdown in circulation, you must be able to simultaneously and very quickly fulfill the following two functions
IO) See the vehicle's stop lights come on. In period
heavy traffic, only the vehicle lights that pre
yields are visible; but for the others, you have to die
place on the left or right ends of the corridor
traffic direction, and despite that, the '1Stop' lights
are not always visible.

20) Etre capable d'apprécier le degré de ralentissement du
ou des véhicules qui précèdent afin de conserver la dis
tance de sécurité de freinage.20) Being able to appreciate the degree of deceleration of the
or vehicles that precede in order to keep the dis
braking safety.

De plus, il faut noter que les feux "Stop" (9) peuvent être confondus avec les autres feux obligatoires tels que les feux de position, de gabarit, et notamment avec le feu arrière antibrouillard. In addition, it should be noted that the "Stop" lights (9) can be confused with the other compulsory lights such as the position and clearance lights, and in particular with the rear fog light.

La définition de ces feux (position, puissance des lampes, surface éclairante, fonctions) est décrite par des textes régle- mentaires dont le respect est garanti par le Service des Mines. The definition of these lights (position, power of the lamps, illuminating surface, functions) is described by regulatory texts, compliance with which is guaranteed by the Service des Mines.

route modification doit faire l'objet d'une étude approfondie et justificative nécessitant une très longue réflexion.route modification must be the subject of an in-depth and supporting study requiring very long reflection.

L'invention présente l'avantage de diminuer le nombre d'accidents et le nombre de véhicules impliqués dans une même collision, tout en évitant de modifier les matériels qui répondent aux prescriptions réglementaires mentionnés ci-dessus.  The invention has the advantage of reducing the number of accidents and the number of vehicles involved in the same collision, while avoiding modifying the materials which meet the regulatory requirements mentioned above.

Cette invention se présente sous la forme d'un boitier indépendant, ou incorporé à un autre équipement. I1 comporte un système électronique (2-3-4) associé à un capteur de ralentissement (I), d'une lampe (5) munie de son réflecteur, et sur la face avant un diffuseur rouge transparent. This invention is in the form of an independent box, or incorporated into other equipment. I1 comprises an electronic system (2-3-4) associated with a slowdown sensor (I), a lamp (5) provided with its reflector, and on the front face a transparent red diffuser.

Monté sur un véhicule, le dispositif (IO) est installé soit à l'intérieur, au niveau du pare brise arrière, soit à l'extérieur mais au-dessus des. feux actuels (pour les poids lourds, à la hauteur des feux de gabarit supérieurs), de telle sorte que le diffuseur rouge soit dirigé vers l'arrière du véhicule. Mounted on a vehicle, the device (IO) is installed either inside, at the rear windscreen, or outside but above. current lights (for heavy goods vehicles, at the height of the upper clearance lights), so that the red diffuser is directed towards the rear of the vehicle.

Le dispositif (IO) assure deux fonctions distinctes et complémentaires, tout en respectant le code de la route. The device (IO) performs two distinct and complementary functions, while respecting the highway code.

Suivant la première fonction, le dispositif (Io) agit comme un rappel des feux "Stop" (9) réglementaires. Dès que la pédale de frein (6) est actionnée, un signal de commande est envoyé sur les feux (9), ainsi que sur la commande (4) qui allume la lampe 5 du dispositif (po). Les feux (9) et la lampe (5) s'allument simultanément, jusqu'à l'arrêt de la pression sur la pédale (6). According to the first function, the device (Io) acts as a reminder of the regulatory "Stop" lights (9). As soon as the brake pedal (6) is actuated, a control signal is sent to the lights (9), as well as to the control (4) which lights the lamp 5 of the device (po). The lights (9) and the lamp (5) light up simultaneously, until the pressure on the pedal (6) stops.

La lampe (5) est plus visible que les lampes (9) du fait de sa position au niveau de la lunette arrière du véhicule pouvant être aperçue plus facilement à travers les différents pare brises des véhicules qui suivent. The lamp (5) is more visible than the lamps (9) because of its position at the rear window of the vehicle which can be more easily seen through the various windshields of the vehicles which follow.

De plus, cette première fonction offre une redondance de signalisation intéressante pour la sécurité car si les deux lampes "Stop" sont grillées, cas tries rares, il reste encore une lampe en état de fonctionnement. In addition, this first function offers an interesting signaling redundancy for safety because if the two "Stop" lamps are burned out, in rare cases, there is still one lamp in working condition.

Suivant la deuxième fonction, le dispositif (I0) agit commme un signal d'alarme, à savoir : lors d'un ralentissement important ou brutal, la lampe (5) se met à clignoter pendant un temps déterminé. Ceci incite les conducteurs des véhicules qui suivent à ralentir fortement pour conserver les distances de sécurité et d'arrêt permettant ainsi d'éviter un accident. According to the second function, the device (I0) acts as an alarm signal, namely: during a significant or sudden slowdown, the lamp (5) starts to flash for a determined time. This encourages the drivers of the vehicles that follow to slow down sharply to keep the safety and stopping distances, thus avoiding an accident.

Le fonctionnement de ce dispositif (lo) n'est pas en contradiction avec le code de la route. The operation of this device (lo) is not in contradiction with the highway code.

La sollicitation du capteur (I) transmet un ordre à la temporisation (2), à la condition que la pédale (6) fournisse une impulsion par le fil (II).  The request of the sensor (I) transmits an order to the time delay (2), on the condition that the pedal (6) provides a pulse by the wire (II).

La temporisation (2) alimente un clignoteur (3) pendant plusieurs secondes quelque soit la durée de l'impulsion (II). Ce clignoteur envoye un signal modulé sur une commande (4) qui a pour effet de faire clignoter la lampe (5). The time delay (2) powers a flasher (3) for several seconds whatever the duration of the pulse (II). This flasher sends a modulated signal on a command (4) which causes the lamp (5) to blink.

Le maintien de l'impulsion (II) et la sollicitation du capteur (I) font clignoter la lampe (5). La disparition de l'impulsion (il) ou de la sollicitation du capteur (I) entraine l'extinction de la lampe (5) après une durée égale à celle définie par la temporisation (2). Maintaining the pulse (II) and activating the sensor (I) cause the lamp (5) to flash. The disappearance of the pulse (II) or of the request of the sensor (I) causes the extinction of the lamp (5) after a duration equal to that defined by the time delay (2).

Le fil (8) permet d'avoir une tension positive en permanence (+ 12 volts continu pour les voitures), le fil (7) est relié à la masse du véhicule (tension nulle), le fil (II) transmet la commande de la pédale (6).  The wire (8) provides permanent positive voltage (+ 12 volts DC for cars), the wire (7) is connected to the vehicle ground (zero voltage), the wire (II) transmits the command to the pedal (6).
