Description

La présente invention concerne un dispositif pour que les véhicules automobiles lisent et respectent d'eux mêmes les diverses limitations de vitesse indiquées. jusqu'à présent, le respect des limitations de vitesse des véhicules automobiles, tenait de l'attention et de la volonté de leur conducteur et pouvait en cas d'excès être la cause d'accidents. certains véhicules sont équipés d'alarmes sonores ou visuelles ou d'une coupure moteur en cas d'excès de vitesse ou d'approche d'obstacle, mais elle doit toujours être programmée à l'avance par le conducteur à chaque fois qu'elle change. The present invention relates to a device for motor vehicles to read and respect for themselves the various speed limits indicated. Until now, compliance with speed limits for motor vehicles has been the focus of the driver's attention and will, and in the event of an excess, could cause accidents. certain vehicles are fitted with audible or visual alarms or an engine cut-off in the event of speeding or approaching an obstacle, but it must always be programmed in advance by the driver each time it exchange.
Le dispositif selon l'invention permet de remédier à cet inconvénient. il comporte en effet selon une première caractéristique un module électronique fixé sous le véhicule qui émet perpendiculairement à ses axes médians, vers le revêtement de la voie de circulation, un rayon lumineux. The device according to the invention overcomes this drawback. according to a first characteristic, it in fact comprises an electronic module fixed under the vehicle which emits perpendicularly to its median axes, towards the surface of the traffic lane, a light ray.
Sur tout le travers et en surface de cette voie, deux étroits miroirs réfléchissants sont fixés face à face à 45 d'inclinaison afin de recevoir du véhicule le rayon et de le renvoyer à 1800 vers un capteur. La distance entre les deux miroirs représente la valeur de l'information à transmettre. On all the cross and on the surface of this track, two narrow reflecting mirrors are fixed face to face at 45 of inclination in order to receive from the vehicle the ray and to return it to 1800 towards a sensor. The distance between the two mirrors represents the value of the information to be transmitted.
En frappant le miroir en amont, le rayon lumineux est parallèlement à la surface de la voie, réfléchi vers le miroir en aval et repart instantanément dans la direction d'où il vient dans un parallélisme précis. un des capteurs dont la distance avec l'émetteur correspond à l'écartement préétabli des miroirs au sol, reçoit l'information de la valeur de la vitesse demandée. By striking the mirror upstream, the light ray is parallel to the surface of the track, reflected towards the mirror downstream and instantly goes back in the direction from which it comes in a precise parallelism. one of the sensors whose distance from the transmitter corresponds to the preset spacing of the mirrors on the ground, receives the information of the value of the requested speed.
Les alignements de capteurs sont disposés en arc de The sensor alignments are arranged in an arc of
<Desc/Clms Page number 2><Desc / Clms Page number 2>
cercle sur 900 à l'avant de l'émetteur et orientés vers lui. circle on 900 at the front of the transmitter and oriented towards it.
L'orientation des miroirs au sol en travers de la voie de circulation est perpendiculaire à l'alignement des capteurs concernés. The orientation of the mirrors on the ground across the taxiway is perpendicular to the alignment of the sensors concerned.
Lorsque le logiciel du module qui reçoit par ailleurs l'information de la vitesse du véhicule trouve que celle-ci est supérieure à celle exigée, il coupe l'électrovanne de l'injection de carburant qui alimentele moteur. When the module software which also receives the vehicle speed information finds that it is higher than that required, it cuts the solenoid valve of the fuel injection which supplies the engine.
Ce logiciel fournit à celui du système de freinage électrique des roues la valeur de l'écart entre la vitesse lue et celle demandée afin que les freins soient actionnés automatiquement avec une puissance inversement proportionnelle.
selon des modes particuliers de réalisation : le logiciel pourra conserver indéfiniment en mémoire sa dernière action tant qu'il n'aura pas détecté une nouvelle valeur. le logiciel peut recevoir l'information de la vitesse du véhicule par un compte tour électronique à palpeur. This software provides that of the electric wheel braking system with the value of the difference between the speed read and that required so that the brakes are applied automatically with inversely proportional power.
according to particular embodiments: the software can keep its last action in memory indefinitely as long as it has not detected a new value. the software can receive vehicle speed information via an electronic feeler lap counter.
La détection de la vitesse zéro, peut représenter une barrière virtuelle d'accès à une voie ou d'un sens interdit et l'alimentation du moteur qui était coupé, pourra de nouveau s'établir électriquement en direct de la boîte de vitesse mais uniquement sur les positions marche arrière ou neutre le rayon lumineux peut être produit soit par un simple LED ou par infrarouge ou par laser ou toute autre source. les miroirs peuvent être fixés sur un panneau support mobile afin d'être installés provisoirement. The detection of zero speed, can represent a virtual barrier to access to a lane or a prohibited direction and the supply of the engine which was cut off, can again be established electrically direct from the gearbox but only in the reverse or neutral positions the light beam can be produced either by a simple LED or by infrared or laser or any other source. the mirrors can be fixed on a mobile support panel in order to be temporarily installed.

Les dessins annexés illustrent l'invention : La figure 1 représente en coupe, le dispositif de l'invention. The accompanying drawings illustrate the invention: Figure 1 shows in section, the device of the invention.
La figure 2 représente en plan d'augmentation des capacités d'information. Figure 2 shows a plan for increasing information capacities.
En référence à ces dessins le dispositif comporte sous le véhicule, un module électronique dont le logiciel fournira une action sur les freins ainsi que sur l'alimentation de carburant ; un émetteur (1) d'un rayon lumineux (2) qui après avoir été projeté sur un jeu de miroirs (3 et 4) vers le sol, revient à 1800parallèlement et à une distance variable à l'avant de l'émetteur dans un secteur de 90 pour être reçu par un des capteurs (8) lequel va transmettre au logiciel la valeur (5) de l'information. chaque capteur a une valeur différente. Tous les capteurs (8) sont alignés sur une même ligne orientée en direction de l'émetteur (1). Plusieurs lignes de capteurs (8) peuvent être disposées dans un rayon de cercle à 900 devant et orientés vers un seul et même émetteur. With reference to these drawings, the device comprises, under the vehicle, an electronic module whose software will provide action on the brakes as well as on the fuel supply; a transmitter (1) with a light beam (2) which after being projected onto a set of mirrors (3 and 4) towards the ground, returns to 1800 at the same time and at a variable distance from the front of the transmitter in a sector of 90 to be received by one of the sensors (8) which will transmit the value (5) of the information to the software. each sensor has a different value. All the sensors (8) are aligned on the same line oriented in the direction of the transmitter (1). Several lines of sensors (8) can be arranged in a radius of a circle 900 in front and oriented towards a single transmitter.
Le deuxième élément est le réflecteur au sol en travers de la voie de circulation où sont fixés à chant les miroirs (3 et 4), d'une largeur d'environ 5cm et inclinés face à face à 45 . The second element is the ground reflector across the traffic lane where the mirrors (3 and 4) are fixed on edge, with a width of around 5cm and inclined face to face at 45.
La distance d'axe en axe entre eux représente la valeur () de l'information qui doit être renvoyée vers le capteur (8). The distance from axis to axis between them represents the value () of the information which must be sent back to the sensor (8).
Cette valeur (5) doit avoir la même direction et la même longueur que celle qui est entre l'émetteur (1) et le capteur (8). This value (5) must have the same direction and the same length as that which is between the transmitter (1) and the sensor (8).
Le dispositif selon l'invention est particulièrement destiné à ne pas dépasser les vitesses demandées. The device according to the invention is particularly intended not to exceed the requested speeds.
