Abstract

The invention concerns an alarm device fitted on several road vehicles, permanently warning the drivers of a critical situation, comprising for each vehicle a transceiver radio operating on the same frequency, constantly in receiving position and ready to signal visually and aurally the presence of a transmitter and indicate whether the transceiver distance increases or decreases. The alarm transmitter is operated manually or automatically. The device is for increasing means of communication between road users, presently restricted to flashing alarm lamps, horns and sound radio transmission (CB-channel) and particularly for avoiding chain accidents in foggy weather.

Description

Système de transπ ssion de signal de danger pour véhicules routiers.Danger signal transmission system for road vehicles.
La présente invention concerne un système de transmission d ' un signal de danger avertissant en permanence les conducteurs de véhicules routiers de l ' existence d ' une si tuat ion cri tique , co prenan€ des émetteurs- récepteurs hertzi.ens foncti.onnant sur la mê -me fréquence, constamment en veille et prêts à signaler l'existence d'un émetteur et d'indiquer si sa distance augmente ou diminue. La mise en fonction émission est faite manuellement ou automatiquement. Mises à part les balises Argos et les balises de montagne conçues pour venir en aide aux navigateurs et aux skieurs-alpinistes, des systèmes de sécurité ayant trait plus particulièrement à la route sont connus, par exemple de la demande française publiée sous le N° FR2670018 ( CHEVALIER Jean-Pierre ) ou du brevet suisse N° CH 664 639, consistant à transmettre des informations aux conducteurs de véhicules routiers. Le dispositif décrit dans ce dernier brevet permet à certains véhicules, tels que véhicules prioritaires ou de secours, de signaler un danger aux autres usagers <?quipés selon ce système. Il permet aussi, par exemple on cas d'accident, de mettre en fonction des bornes- relais convoyant le signal de danger.The present invention relates to a system for transmitting a danger signal constantly warning drivers of road vehicles of the existence of a critical condition, including the use of hertzi.ens transceivers operating on the same frequency, constantly on standby and ready to signal the existence of a transmitter and to indicate whether its distance increases or decreases. The transmission function is done manually or automatically. Apart from the Argos beacons and the mountain beacons designed to help navigators and ski-mountaineers, safety systems relating more particularly to the road are known, for example from the French application published under the number FR2670018 (CHEVALIER Jean-Pierre) or Swiss patent N ° CH 664 639, consisting in transmitting information to drivers of road vehicles. The device described in this latter patent allows certain vehicles, such as priority or emergency vehicles, to signal a danger to other users equipped with this system. It also allows, for example in the event of an accident, to activate the relay terminals conveying the danger signal.
L'inconvénient de ces systèmes est que la diffusion du signal procède d'une gestion centralisée entraînant un délai et qu'il faut envisager une infrastructure pour émettre ce signal.The disadvantage of these systems is that the signal diffusion proceeds from a centralized management leading to a delay and that an infrastructure must be envisaged to emit this signal.
Or chacun sait, pour l'avoir observé notamment sur autoroute, que les conducteurs cherchent spontanément à avertir ceux qui les suivent d'un danger survenant en amont de la circulation de façon bien imparfaite, par la mise en-fonction des feux de détresse en plus de l'allumage répété des feux stop enseigné traditionnellement dans le code de la route. Mais ces pratiques trouvent leurs limites d'une part dans les conditions météorologiques qui peuvent entraver la vision de ces feux, notamment en cas de pluie ou de brouillard, d'autre part dans les aléas liés au terrain que parcourt la route, tels que virage ou relief; elles trouvent par ailleurs une limite lorsque le conducteur est déjà impliqué dans un accident, ou en cas d'absence de réflexes de sa part; de plus, en conduite urbaine un danger existant dans une rue transversale rte peut pas être signalé par ce moyen visuel. Il existe donc un besoin non satisfait chez les usagers de la route qui sont témoins de l'imminence d'un danger, de pouvoir signaler l'existence de ce danger de façon immédiate et par tous les temps aux autres usagers.Now everyone knows, having observed it in particular on the motorway, that drivers spontaneously seek to warn those following them of a danger occurring upstream of traffic in a very imperfect way, by switching on the hazard lights in in addition to the repeated lighting of brake lights traditionally taught in the highway code. But these practices find their limits on the one hand in the meteorological conditions which can hinder the vision of these lights, in particular in the event of rain or fog, on the other hand in the vagaries linked to the ground which the road, such as bend or relief; they also find a limit when the driver is already involved in an accident, or in the absence of reflexes on his part; moreover, in urban driving a danger existing in a transverse street rte cannot be signaled by this visual means. There is therefore an unmet need among road users who witness the imminence of a danger, to be able to report the existence of this danger immediately and in all weathers to other users.
La présente invention se propose de résoudre ce problème par un dispositif comportant selon une première caractéristique un émetteur-récepteur hertzien fonctionnant sur la même fréquence, monté à l'intérieur de chaque véhicule routier, constamment en veille réceptive lorsque ce véhicule est en service et capable de détecter un appareil semblable en mode émission, de convertir le signal hertzien en signaux de bord visuels et auditifs et d'indiquer si la distance émetteur-récepteur croît ou décroît par analyse de la puissance du signal reçu. La* mise en fonction émission du dispositif est faite manuellement en cas de danger à signaler ou automatiquement.The present invention proposes to solve this problem by a device comprising, according to a first characteristic, a radio transmitter and receiver operating on the same frequency, mounted inside each road vehicle, constantly in receptive standby when this vehicle is in service and capable to detect a similar device in transmission mode, to convert the radio signal into visual and auditory on-board signals and to indicate whether the transmitter-receiver distance increases or decreases by analysis of the strength of the received signal. * The device is put into emission function manually in the event of a danger to be reported or automatically.
Dans une forme particulière de réalisation de l'invention, la mise en fonction de l'émetteur d'alarme est faite soit manuellement par le conducteur de l'un quelconque des véhicules équipés, par exemple s'il perçoit un danger et veut en avertir les autres usagers qu'il présume être encore trop loin pour le percevoir, soit déclenchée automatiquement par la détection d'un choc, d'une gîte exagérée du véhicule, de fumée, d'élévation de température ou d'opération d'airbag.In a particular embodiment of the invention, the activation of the alarm transmitter is done either manually by the driver of any of the equipped vehicles, for example if he perceives a danger and wants to warn of it the other users whom he presumes to be still too far to perceive it, is triggered automatically by the detection of a shock, an exaggerated list of the vehicle, smoke, temperature rise or airbag operation.
Dans une forme particulière de réalisation de l'invention, l'alimentation en énergie du dispositif est indépendante pour permettre un fonctionnement même en cas de défaut de l'alimentation normale.In a particular embodiment of the invention, the power supply to the device is independent to allow operation even in the event of a fault in the normal supply.
Dans une forme particulière de réalisation de l'invention, les signaux de bord sont mis sous une forme permettant au conducteur d'évaluer la nature et la gravité du risque lié à l'alarme reçue après analyse du signal détecté, différentiable ou non. Dans une forme particulière de réalisation de l'invention, lors de la mise en fonction de l'émetteur d'alarme sur un véhicule, la cause, la date et l'heure de cette mise en fonction sont enregistrées dans une mémoire du dispositif. Cette mémoire pourra avantageusement n'être effaçable que par des moyens accessibles seulement à des personnes chargées de contrôles et conservera un historique des déclenchements du dispositif.In a particular embodiment of the invention, the edge signals are put under a form allowing the driver to assess the nature and severity of the risk linked to the alarm received after analysis of the detected signal, differentiable or not. In a particular embodiment of the invention, when the alarm transmitter is put into operation on a vehicle, the cause, the date and the time of this activation are recorded in a memory of the device. This memory may advantageously be erasable only by means accessible only to persons responsible for checks and will keep a history of the trips of the device.
Dans une forme particulière de réalisation de l'invention, certains véhicules sont équipés d'émetteurs plus puissants ou envoyant un signal différentiable , notamment les véhicules prioritaires et certains véhicules sont équipés de récepteurs plus sensibles ou directifs permettant de localiser un éventuel émetteur, notamment les véhicules des forces de l'ordre.In a particular embodiment of the invention, certain vehicles are equipped with more powerful transmitters or send a differentiable signal, in particular priority vehicles and certain vehicles are equipped with more sensitive or directive receivers making it possible to locate a possible transmitter, in particular the law enforcement vehicles.
Dans une forme particulière de réalisation de l'invention, le dispositif est logé dans un boîtier présentant une résistance améliorée. Cette résistance peut notamment être améliorée en cas de chocs, d'exposition au feu ou à des élévations de température, ainsi qu'à une immersion. In a particular embodiment of the invention, the device is housed in a housing having improved resistance. This resistance can in particular be improved in the event of impact, exposure to fire or temperature increases, as well as immersion.
