Abstract

The invention relates to marks situated on the windscreen or on the rear view mirror of a vehicle, intended to frame a second vehicle, the one in front to the one behind, in order to keep a safe distance when the relative speed is rapidly reduced. It consists of lines delimiting characteristic zones of the roadway or of a reference vehicle. The device can be used for all vehicles driving in a line. <IMAGE>

Description

REPERES, VISIBLES SUR LE PARE-BRISE OU LE RETROVISEUR D'UN VEHICULE, COMPASS VISIBLE ON THE WINDSHIELD OR THE MIRROR OF A VEHICLE
POUR EVALUER LES DISTANCES LE SEPARANT D'AUTRES VEHICULES. TO ASSESS THE DISTANCE SEPARATING OTHER VEHICLES.

L'objet de la présente invention concerne des repères situés sur les véhicules ( en particulier pare-brise ou rétroviseur ), destinés à The object of the present invention relates to markings on the vehicle (in particular windscreen or mirror), for
cadrer l'image du véhicule qui précède ou qui suit, pour pouvoir ainsi évaluer le risque de choc avec l'un d'eux, en cas d'une réduction trop raide de distance. frame the picture of the vehicle ahead or following, order and evaluate the risk of collision with any of them, in case of a too steep reduction in distance.

A ce jouir, le procédé expérimenté ponctuellement, consiste à tracer To enjoy the occasionally experienced process is to draw
s1ir la chaussée des repères - chevrons - à des distances régulières s1ir pavement markers - rafters - at regular distances
(40 m); (40 m); la distance de 80m entre deux véhicules se suivant est considérée comme distance de sécurité; the distance of 80m between two vehicles following is considered safety distance; cette distance se réduisant, le danger se précise polir devenir important à partir de la distance critique de 40m, comprise entre deux repères. this distance is reduced, the danger is precisely polished become important from the critical distance of 40m between two pins. Cette expérience est limitée et la généraliser demanderait aux collectivités des efforts financiers sur des milliers de km et slir tolites les voies. This experience is limited and generalized ask the authorities of the financial efforts of thousands of km and SLIRE tolites ways.

Il est donc utile d'utiliser un procédé moins onéreux, à efficacité comparable ou meilleure, ce qui est le cas proposé puisque le risque est évaluable en,avant et en arrière du véhicule équipé de repères. It is therefore useful to use a less expensive process, with comparable or better efficiency, which is the proposed case since the risk can be evaluated in before and behind the vehicle equipped with pins.

Le dispositif selon l'invention consiste, en première approche, e lignes disposées sur le pare-brise ou le rétroviseur, en forme de cadre et distantes entre elles selon les dimensions de l'image d'un véhicule pris en référence. The device according to the invention consists, in a first approach, e lines arranged on the windscreen or mirror, frame-shaped and separated from each other according to the image size of a vehicle used as a reference. Les dimensions de l'image sont calculées en fonction des dimensions du véhicule de référence auxquelles on applique le rapport: distance de l'oeil au pare-brise (ou rétroviseur) sir distance de l'oeil ai véhicule observé, d'une part à la distance de sécurité, d'autre part à la distance critique ( FIG II' et I-3). The dimensions of the image are calculated based on the dimensions of the reference vehicle to which is applied the ratio: distance from the eye to the windscreen (or mirror) Sir distance from the eye vehicle have observed, on the one hand the safety distance, of the other part than the critical distance (FIG II 'and I-3). Les schémas I et 2 de la FIS I correspondent à des distances intermédiaires; Schemes I and 2 of the SIF I correspond to intermediate distances; la meme présentation se retrolive si les FIG: 2, 3, 4. the same presentation retrolive if the FIG: 2, 3, 4.

Le cadre de la FIG I peut être remplacé par des repères horizontaux tenant compte, non de l'encombrement des véhicule observé, meis de l'image des repères virtuels tracés tous les 40m sir les alitorolites: The FIG I frame can be replaced by horizontal pins into account, not the congestion observed vehicle meis image virtual pins 40m plots all the alitorolites Sir:
FIG 2, 4 et 4'. FIG 2, 4 and 4 '. Tracer ces repères implique de tenir compte de la hau- teur (5) de l'oeil et de l'inclinaison dti pare-brise (ó) ciii reçoit l'image. Draw these marks implies taking into account the heights tor (5) of the eye and the dti tilt windshield (ó) ciii receives the image.

La FIG 3 N'est alitre que la FIG I débarrassée des repères verticaux; FIG 3 Is alitre the FIG I free of vertical guides; elle ne tient compte que de la hauteur de l'image de la voitire de référence lorsque celle-ci se trouve aux distances remarquables et également de l'inclinaison du pare-brise. it only takes into account the height of the image of the reference voitire when it is the remarkable distances and also the inclination of the windshield.

La FIG 4 est, elle, débarrassée des repères horizontaux et ne tient compte que de la largeur (9') du véhicule, éventuellement des feux de position. FIG 4 is her free of horizontal pins and only takes into account the width (9 ') of the vehicle, possibly sidelights. Les repères verticaux s'écartent vers le bas selon l'inclinaison du pare-brise (9). The vertical pins deviate downwards according to the inclination of the windshield (9). Leur longueur est suffisante (10) pour que l'oeil soit toujours sollicité, quelle que soit leur hauteur. Their length is sufficient (10) so that the eye is always applied, regardless of their height.

La FIG 5 indique l'utilisation des repères verticaux sur le rétroviseur, pour des images de véhicules suivant à des distances remarquables. FIG 5 shows the use of vertical pins on the rear view mirror for vehicles according images at remarkable distances.

Exemple de calcul: L'oeil est à 40 cm du rétroviseur; Calculation example: The eye is 40 cm mirror; la voiture de référence a I,6 m de large. the reference car I, 6 m wide.

Si A3 = 100 m les repères de l'image I' sont distants de: If A3 = 100 m pins of the image I 'are separated by:
I cm x (I60 x 40) : IOOOC = 0,64 cm. I 'x (I60 x 40): IOOOC = 0.64 cm.

Si AB' = 60 m, les repères de l'image 3 sont distants de: 1 cm x (160 x 40) : 6000 = 1,06 cm. If AB = 60 m, the pins of the image 3 are distant from: 1 cm x (160 x 40): 6000 = 1.06 cm.

Précision complémentaire: Pour passer de B à B' (40 m), la voiture a mis 3 secondes: la différence de vitesse avec A est de 4 kmh h env; additional information: To change from B to B '(40 m), the car has 3 seconds with the speed difference A is 4 kmh h env; elle sera an niveali de A en: 3 : 4C x 60 = 4,5 sec. it will year niveali A in 3: 4C x 60 = 4.5 sec. A ne doit pas débotter polir doîibler; A must not débotter polish doîibler;
Si BB' est parcouru en 5 secondes, il restera 7,5 secondes à A pour dolibler, si son motelir a des réserves; If BB 'is crossed by 5 seconds, it will remain 7.5 seconds for A dolibler if his motelir has reservations; la marge est étroite; the margin is narrow;
Un coup d'oeil de 1 dans la position I' et un colip d'oeil 6 secondes après lui indiquera s'il peut doubler en sécurité. A stroke of the eye in one position I 'and a look COLIP 6 seconds will indicate if he can double security.

Le tracé des repères peut se faire par tour moven connu, sur ou dans le verre. The track markers can be by known Moven turn on or in the glass.

Cette invention s'appliqXle à toit véhiclile se déplaçant en file. This invention appliqXle to véhiclile roof moving in single file.

Les valeurs indiquées ne le sont qu'à titre d'exemple. The values ​​are only examples.

Le sollicitation des usagers petit etre accrue par l'adjonction le slogans, par exemple: " Mesurer le risque, ça, c'est conduire! ". The solicitation small users be increased by adding the slogans, including: "Measuring the risk, that's driving".
