Abstract
Description
La présente invention concerne un système de gestion de la circulation de véhicules automobiles à un carrefourThe present invention relates to a motor vehicle traffic management system at a crossroads
Dans l'état de la technique, ces systèmes de gestion de la circulation comprennent des feux de signalisation tricolores disposés dans chaque voie menant au carrefour, ces feux de signalisation étant activés par des moyens de commande.In the state of the art, these traffic management systems include three-color signaling lights arranged in each lane leading to the crossroads, these signaling lights being activated by control means.
Ces moyens de commande comprennent par exemple une minuterie ou sont reliés à des moyens de surveillance de la densité de circulation pour commander ces feux en fonction de celle-ci.These control means comprise for example a timer or are connected to traffic density monitoring means to control these lights as a function thereof.
On conçoit donc qu'aucun des systèmes de gestion mis en oeuvre dans l'état de la technique ne prend en compte les paramètres caractéristiques des véhicules et de leur fonctionnement à l'approche du carrefour et que cette situation peut présenter un certain nombre d'inconvénients dans la mesure où dans certains cas elle peut entraîner des blocages inutiles au niveau de ce carrefour.It is therefore understandable that none of the management systems implemented in the state of the art takes into account the characteristic parameters of the vehicles and their operation when approaching the crossroads and that this situation can present a certain number of disadvantages insofar as in certain cases it can cause unnecessary blockages at this crossroads.
Le but de l'invention est donc de résoudre ces problèmes en proposant un système de gestion de la circulation de véhicules automobiles à un carrefour qui soit simple, fiable et qui permette de gérer de façon très précise la circulation.The object of the invention is therefore to solve these problems by proposing a system for managing the circulation of motor vehicles at a crossroads which is simple, reliable and which makes it possible to manage traffic very precisely.
A cet effet, l'invention a pour objet un système de gestion de la circulation de véhicules automobiles à un carrefour, caractérisé en ce que les véhicules comprennent des moyens d'émission d'un message d'informations concernant des paramètres caractéristiques du véhicule et de son fonctionnement à l'approche du carrefour, en direction de moyens de réception desdites informations, en regard de chaque voie menant au carrefour, la sortie de ces moyens de réception étant reliée à des moyens de traitement desdites informations et de commande de moyens de signalisation, implantés dans le carrefour, pour gérer la circulation en fonction desdites informations.To this end, the subject of the invention is a system for managing the circulation of motor vehicles at a crossroads, characterized in that the vehicles comprise means for transmitting an information message concerning parameters characteristic of the vehicle and of its operation when approaching the crossroads, in the direction of means for receiving said information, opposite each lane leading to the crossroads, the output of these reception means being connected to means for processing said information and control signaling means, located in the crossroads, to manage traffic according to said information.
Avantageusement, les messages d'informations comprennent au moins une partie d'identification de chaque véhicule, un bit d'indication de l'actionnement ou non du clignotant droit du véhicule, un bit d'indication de l'actionnement ou non du clignotant gauche du véhicule, et une partie de contrôle d'erreurs.Advantageously, the information messages include at least one part for identifying each vehicle, a bit for indicating whether or not the right turn signal of the vehicle is actuated, a bit for indicating whether or not the left turn signal is actuated of the vehicle, and an error checking part.
Avantageusement également, les moyens d'émission et de réception fonctionnent dans le spectre infrarouge.Advantageously also, the transmission and reception means operate in the infrared spectrum.
L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :
- la Fig.1 illustre l'implantation générale d'un système selon l'invention; et
- la Fig.2 représente un schéma synoptique de moyens de traitement d'informations et de commande d'une balise entrant dans la constitution d'un système selon l'invention.
- Fig.1 illustrates the general layout of a system according to the invention; and
- Fig.2 shows a block diagram of information processing means and control of a beacon forming part of a system according to the invention.
Ainsi qu'on peut le voir sur la Fig.1, le système de gestion de la circulation de véhicules automobiles à un carrefour, selon l'invention, est basé sur le fait que chaque véhicule automobile, par exemple 1, est équipé de moyens 2 d'émission d'un message d'informations concernant des paramètres caractéristiques du véhicule et de son fonctionnement à l'approche du carrefour, en direction de moyens 3 de réception de ces informations, disposés en regard de chaque voie menant au carrefour. Ces moyens sont disposés par exemple sur une balise 4 au centre du carrefour, mais peuvent également être disposés à d'autres endroits de celui-ci.As can be seen in FIG. 1, the system for managing the circulation of motor vehicles at a crossroads, according to the invention, is based on the fact that each motor vehicle, for example 1, is equipped with
Cette balise comporte donc des moyens de réception d'informations en regard de chaque voie menant au carrefour, ces moyens étant au nombre de quatre dans le cas particulier représenté sur cette figure.This tag therefore includes means for receiving information opposite each lane leading to the crossroads, these means being four in number in the particular case shown in this figure.
Comme on peut le voir sur la Fig.2, ces moyen de réception d'informations 3 sont reliés par l'intermédiaire de moyens d'amplification 5 et d'un décodeur 6 à des moyens 7 de traitement des informations reçues des véhicules. Ces moyens 7 permettent également de commander par l'intermédiaire de moyens d'amplification 8, des moyens de signalisation 9 implantés dans le carrefour pour gérer la circulation en fonction desdites informations.As can be seen in FIG. 2, these means for receiving
Il est à noter que le système décrit sur cette Fig.2, comporte quatre parties identiques reliées à ces moyens 7 de traitement d'informations, chaque partie correspondant à des moyens disposés en regard de l'une des quatre voies menant au carrefour. Ces parties ne seront donc pas décrites plus en détail.It should be noted that the system described in this Fig. 2 comprises four identical parts connected to these information processing means 7, each part corresponding to means arranged opposite one of the four lanes leading to the crossroads. These parts will therefore not be described in more detail.
Les moyens de traitement des informations reçoivent donc des informations en provenance de chaque voie menant au carrefour et analysent la situation résultant desdites informations pour commander en conséquence, les moyens de signalisation. Ces moyens de signalisation sont constitués par exemple par des feux tricolores ou par un gyrophare 10 disposé par exemple sur la balise et avertissant les conducteurs des véhicules d'un danger quelconque.The information processing means therefore receive information from each lane leading to the crossroads and analyze the situation resulting from said information to control the signaling means accordingly. These signaling means are constituted for example by three-color lights or by a rotating
Il est à noter que les moyens d'émission et de réception de messages d'informations peuvent travailler dans le spectre infrarouge ou en hyperfréquence, afin d'assurer une bonne transmission des informations.It should be noted that the means for transmitting and receiving information messages can work in the infrared or microwave spectrum, in order to ensure good transmission of information.
Les messages d'informations comprennent au moins une partie d'identification de chaque véhicule, un bit d'indication de l'actionnement ou non du clignotant droit du véhicule, un bit d'indication de l'actionnement ou non du clignotant gauche du véhicule, éventuellement un bit d'indication de l'actionnement ou non des freins du véhicule et/ou une partie d'indication de la vitesse de celui-ci et une partie de contrôle d'erreurs.The information messages include at least an identification part of each vehicle, a bit indicating whether or not the indicator is actuated. right of the vehicle, a bit indicating the actuation or not of the left indicator of the vehicle, possibly a bit indicating the actuation or not of the brakes of the vehicle and / or a part indicating the speed of that and a part of error checking.
Ces différentes informations sont transmises en série par les moyens d'émission du véhicule dès que celui-ci entre dans le champ de surveillance de la balise. Le déclenchement de l'émission peut être assuré par tous moyens appropriés de type connu, comme des détecteurs de proximité, etc... Ces informations transmises sous forme série, sont ensuite amplifiées puis décodées respectivement par les moyens 5 et 6 de la Fig.2 et entrées dans les moyens 7 de traitement de ces informations.This different information is transmitted in series by the vehicle's transmission means as soon as it enters the surveillance field of the beacon. Triggering of the transmission can be ensured by any appropriate means of known type, such as proximity detectors, etc. This information transmitted in serial form is then amplified and then decoded respectively by
Il est à noter que ces moyens de traitement d'informations et de commande peuvent être constitué par tout microprocesseur approprié qui, en fonction des informations émanant des véhicules circulant sur les différentes voies menant au carrefour, commandent les moyens de signalisation 9 pour gérer la circulation en fonction de celles-ci.It should be noted that these information processing and control means can be constituted by any suitable microprocessor which, as a function of the information emanating from the vehicles traveling on the different lanes leading to the crossroads, control the signaling means 9 to manage the traffic. based on these.
Ainsi qu'on l'a mentionné précédemment, les moyens de traitement d'informations 7 en analysant les différentes informations provenant des véhicules, et en particulier les informations concernant l'actionnement des clignotants des véhicule, déterminent par exemple si les routes suivies par des véhicules, vont simplement se croiser ou se couper, ce qui présente un certain nombre de risques.As mentioned previously, the information processing means 7 by analyzing the various information coming from the vehicles, and in particular the information concerning the actuation of the indicators of the vehicles, determine for example if the routes followed by vehicles, will simply cross or cut, which presents a certain number of risks.
En fonction de cette analyse, ce moyens commandent les moyens de signalisation pour autoriser le croisement des véhicules ou arrêter l'un de ceux-ci.Based on this analysis, these means control the signaling means to authorize the crossing of vehicles or stop one of them.
Il en va de même si de véhicules arrivant sur deux voies différentes, souhaitent passer sur une autre voie sans se croiser.The same applies if vehicles arriving on two different lanes, wish to pass on another lane without crossing.
Ainsi qu'on l'a mentionné précédemment, les moyens de signalisation peuvent être constitués par des feux tricolores, de type connu, implantés dans chaque voie menant au carrefour. Il va de soi que d'autres modes de réalisation de ces moyens de signalisation peuvent être envisagés.As mentioned previously, the signaling means can be constituted by three-color lights, of known type, located in each lane leading to the crossroads. It goes without saying that other embodiments of these signaling means can be envisaged.
En effet, ces moyens de signalisation peuvent également être fixés sur la balise disposée au centre du carrefour en regard de chaque voie.Indeed, these signaling means can also be fixed on the beacon placed in the center of the crossroads opposite each lane.
Ces moyens peuvent également être constitués par le gyrophare 10 disposé dans la partie supérieure de la balise et commandé par les moyens de traitement et de commande en fonction des informations émanant des véhicules lorsqu'il y a un risque de collision.These means can also be constituted by the rotating
Le système selon l'invention permet donc à des véhicules automobiles, circulant dans une zone déterminée, de transmettre des informations vers l'infrastructure routière afin d'augmenter la sécurité et le confort des usagers.The system according to the invention therefore allows motor vehicles, circulating in a determined area, to transmit information to the road infrastructure in order to increase the safety and comfort of the users.
Parmi les nombreuses situations pouvent se présenter, il est possible par exemple de gérer la circulation de véhicules en convoi ou en file, avec de densités de trafic relativement élevée.Among the many situations that may arise, it is possible, for example, to manage the circulation of vehicles in convoy or in line, with relatively high traffic densities.
L'utilisation de la transmission d'informations dans le spectre infrarouge ou en hyperfréquence permet d'établir une transmission d'informations stable et sélective des informations entre le véhicule mobile et les parties fixes du système.The use of information transmission in the infrared or microwave spectrum makes it possible to establish stable and selective information transmission of information between the mobile vehicle and the fixed parts of the system.
Les moyens d'émission d'information peuvent être constitués par des diodes émettant dans le spectre infrarouge, ces moyens étant par exemple intégrés dans le bouclier avant du véhicule en lieu et place d'un projecteur anti-brouillard. D'autres emplacements sont également possibles comme par exemple la calandre avant du véhicule.The means for transmitting information can be constituted by diodes emitting in the infrared spectrum, these means being for example integrated in the front bumper of the vehicle in place of a fog light. Other locations are also possible such as for example the front grille of the vehicle.
Le moyens de réception d'informations peuvent quant à eux être constitués par des photodiodes fonctionnent dans le spectre infrarouge, ces photodiodes étant disposes par exemple sur la balise disposée au centre du carrefour, en regard de chaque voie menant à celui-ci.The information reception means can for their part be constituted by photodiodes operating in the infrared spectrum, these photodiodes being arranged for example on the beacon placed at the center of the crossroads, opposite each path leading to it.
Il est également à noter que les diodes émettant dans le spectre infrarouge peuvent être commandées par un processeur spécialisé de communication qui peut être constitué par un générateur de protocole interfaçable avec un microprocesseur qui est déjà utilisé dans la fonction multiplexage connue des véhicules automobiles pour l'acquisition et la transmission de différentes informations.It should also be noted that the diodes emitting in the infrared spectrum can be controlled by a specialized communication processor which can be constituted by a protocol generator interfaceable with a microprocessor which is already used in the known multiplexing function of motor vehicles for the acquisition and transmission of different information.
Enfin, la commande des différents moyens de signalisation comme par exemple les feux tricolores ou le gyrophare, est assurée le temps nécessaire au franchissement du carrefour par les véhicules, en toute sécurité, avant analyse d'une nouvelle situation.Finally, the control of the various signaling means such as for example the traffic lights or the rotating beacon, is ensured the time necessary for the vehicles to cross the crossroads, in complete safety, before analysis of a new situation.
