Abstract

The electronic driving mirror has a television camera secured on the rear bumper of a car and providing a field of view of about 180 deg., to ensure that both sides of the road are visible at a distance of several metres. The camera is coupled through a cable to a television screen by way of an image inverter, which is located close to the driver and may be switched out of circuit if desired. The camera may be pivotably driven by a motor controlled by the driver by means of a joy-stick tyre lever. The camera may be positioned centrally of or to one side of the car.

Description

L'invention concerne un dispositif rétroviseur électronique. The invention relates to an electronic rearview device.

Les dispositifs rétroviseurs connus à ce jour utilisent un ou plusieurs miroirs permettant par leur surface, leur forme, et/ou leurs disposition d'obtenir une vue aussi large que possible de l'espace situé à l'arrière d'un véhicule. Ils ont la forme soit d'un simple miroir, soit, plus rarement, d'un périscope. Rearview devices known to date use one or more mirrors allowing, by their surface, their shape, and / or their arrangement, to obtain a view as wide as possible of the space situated at the rear of a vehicle. They have the shape either of a simple mirror or, more rarely, of a periscope.

Dans tous les cas, leur position est préréglée pour obtenir une image du secteur dont on doit connattre la situation le plus fréquemment. In all cases, their position is preset to obtain an image of the sector whose situation must be known most frequently.

Ces dispositifs ont pour inconvénient de présenter un ou plusieurs angles morts dans la vision vers l'arrière. Pour pallier cet inconvénient, la solution la plus fréquemment employée est la disposition e plusieurs miroirs dont l'ensemble permet de balayer sensiblement tout le secteur à l'arrière du véhicule, ce qui entraîne un encombrement notable à l'intérieur et à l'extérieur du véhicule. These devices have the disadvantage of having one or more blind spots in the rear view. To overcome this drawback, the most frequently used solution is the arrangement of several mirrors, the assembly of which makes it possible to sweep substantially the entire sector at the rear of the vehicle, which results in considerable bulk inside and outside. of the vehicle.

L'invention vise à éliminer ce défaut et concerne un dispositif de rétrovision, caractérisé en ce qu'il est constitué par une caméra de télévision associée en circuit fermé avec un récepteur d'images, la caméra étant orientée vers l'arrière et le récepteur d'images étant disposé sur le tableau de bord dans le champ de vision du conducteur. The invention aims to eliminate this defect and relates to a rear view device, characterized in that it is constituted by a television camera associated in closed circuit with an image receiver, the camera being oriented towards the rear and the receiver of images being placed on the dashboard in the driver's field of vision.

Selon un premier mode de réalisation, la caméra de télévision comporte un dispositif optique grand, angulaire, lui permettant, tout en demeurant fixe en position de couvrir un champ suffisamment large pour apercevoi g oute sur laquelle circule le véhicule à l'arrière de celui-c
Selon un deuxième mode de réalisation, la caméra est montée piv tante sur un support et est commandée par tout moyen approprié lui permettant de balayer tout le champ de vision suffisant pour aller d'un côté à l'autre de la route sur laquelle circule le véhicule.According to a first embodiment, the television camera comprises a large, angular optical device, allowing it, while remaining stationary in position to cover a field wide enough to perceive all of which the vehicle is traveling behind it. vs
According to a second embodiment, the camera is pivotally mounted on a support and is controlled by any appropriate means allowing it to scan the entire field of vision sufficient to go from one side to the other of the road on which the vehicle.

A titre d'exemple, non limitatif, et pour faciliter la comprétension de l'invention, on a représenté aux dessins annexes :
Figure 1 - une vue schématique, en plan, représentant le premier mode de réalisation ;
Figure 2 - une vue schématique, en plan, représentant le deuxième mode de réalisation ;
Figure 3 - un schéma de montage du circuit fermé de télévision.By way of non-limiting example, and to facilitate understanding of the invention, the accompanying drawings show:
Figure 1 - a schematic plan view showing the first embodiment;
Figure 2 - a schematic plan view showing the second embodiment;
Figure 3 - a circuit diagram of the closed circuit television.

En se reportant à la figure 1, on voit que sur le pare-choc arrière 2 du véhicule 1, est montée une caméra électronique fixe 3 ayant un angle de champ A de l'ordre de 80 , tel que les deux côtés de la route soient visibles à une distance de l'ordre de quelques metres. La caméra 3 est, de préférence, placée sur le coté du véhicule se trouvant vers l'axe mcdicn de la route. Referring to Figure 1, we see that on the rear bumper 2 of the vehicle 1, is mounted a fixed electronic camera 3 having a field angle A of about 80, such that the two sides of the road are visible at a distance of the order of a few meters. The camera 3 is preferably placed on the side of the vehicle located towards the center line of the road.

Cette caméra électronique 3 est reliée par un câblage 3a à un écran 6 analogue à un écran de télévision avec, éventuellement, interposition d'un dispositif intérieur d'images 7. This electronic camera 3 is connected by a wiring 3a to a screen 6 analogous to a television screen with, possibly, the interposition of an internal image device 7.

Cette disposition permet au conducteu-r du véhicule 1 d'avoir en permanence une vision complète, sans aucun angle mort, vers l'arrière de son véhicule. Au lieu d'un montage sur le pare-choc arrière, on peut prévoir un logement dans le bloc de feux de signalisation arrière gauche. This arrangement allows the driver-r of vehicle 1 to have a permanent complete vision, without any blind spot, towards the rear of his vehicle. Instead of mounting on the rear bumper, a housing can be provided in the left rear signal light unit.

D'autre part, l'intérieur d'images étant muni d'une commande permettant de le brancher ou de le débrancher à volonté, ce dispositif permet d'effectuer toute marche arrière sans que le conducteur soit obligé de se retourner complètement sur lui-même. On the other hand, since the interior of the images is provided with a control allowing it to be plugged in or unplugged at will, this device makes it possible to carry out any reverse gear without the driver having to turn around completely. even.

L'image donnée par une caméra à grand angle de vision pouvant ne pas être assez précise, on peut selon une variante de réalisation représentée aux figures 2 et 3employer une caméra montée à pivotement sur un axe vertical, de façon à pouvoir balayer tout le champ de vision. The image given by a camera with a wide angle of vision may not be precise enough, it is possible, according to an alternative embodiment represented in FIGS. 2 and 3, to employ a camera pivotally mounted on a vertical axis, so as to be able to scan the entire field of vision.

La caméra peut être commandée de façon à osciller de façon continue entre deux positions extrêmes II et III, mais elle peut également n'osciller que sur commande. The camera can be controlled so as to oscillate continuously between two extreme positions II and III, but it can also oscillate only on command.

Dans ce cas le dispositif moteur 4, qui peut être un petit moteur électrique ou un solénoïde agissant sur une tringlerie appropriée (qui n'est pas représentée, car elle est à portée de tout homme de l'artj, est disposée de façon qu en position de repos la caméra 3 soit dans la position I son axe optique tant parallèle à celui du véhicule. In this case the motor device 4, which can be a small electric motor or a solenoid acting on an appropriate linkage (which is not shown, because it is within reach of any person skilled in the art, is arranged so that in rest position the camera 3 is in position I its optical axis both parallel to that of the vehicle.

Le moyen moteur 4 est commandé par un levier 5 pouvant occuper une position médiane et deux positions extrêmes I et II (figure 3). The drive means 4 is controlled by a lever 5 which can occupy a middle position and two extreme positions I and II (FIG. 3).

Lorsque le levier 5 est mis en position II (ou III), le moyen moteur 4 provoque le déplacement de la caméra 3 qui vient en position II (ou III).  When the lever 5 is put in position II (or III), the motor means 4 causes the displacement of the camera 3 which comes in position II (or III).

Dans ce cas également, le -circuit peut comporter un inverseur d'images 7 commandé par un interrupteur 7a. Le fonctionnement de la caméra 3 peut également être commandé par un interrupteur 8. In this case also, the circuit can include an image reverser 7 controlled by a switch 7a. The operation of the camera 3 can also be controlled by a switch 8.

Cette disposition permet au conducteur de diriger à volonté la caméra 3 vers la zone qu'il désire inspecter à l'arrière de son véhicule. This arrangement allows the driver to direct the camera 3 at will to the area he wishes to inspect at the rear of his vehicle.

Selon une variante de réalisation, la commande du mouvement de la caméra 3 peut être couplée avec la commande 9 des feux 10 de changement de direction. According to an alternative embodiment, the control of the movement of the camera 3 can be coupled with the control 9 of the direction change lights 10.

Dans les exemples représentés aux figures 1 et 2, la caméra 3 est montée sur le parechoc arrière du véhicule 1, mais il est bien évident qu'elle peut être montée en tout endroit approprié. En particulier, si le véhicule 1 est employé pour tracter une remorque ou une caravane, la caméra 3 peut être amovible de façon à pouvoir être placée à l'arrière de la remorque ou de la caravane en rallongeant le conducteur 3a. In the examples shown in Figures 1 and 2, the camera 3 is mounted on the rear bumper of the vehicle 1, but it is obvious that it can be mounted in any suitable place. In particular, if the vehicle 1 is used to tow a trailer or a caravan, the camera 3 can be removable so that it can be placed at the rear of the trailer or the caravan by extending the driver 3a.

Dans les exemples représentés, le récepteur d'images 6 est placé sur le tableau de bord, mais il peut être placé en tout autre endroit visible par le conducteur,
La caméra peut être également équipée d'un disposition à focale variable, communément appelé "Zoom", dont la commande, non représentée, peut être située sur le tableau de bord, ce qui permet au conducteur d'a jus- ter la vision vers l'arrière afin d'avoir une meilleure appréciation de distance à laquelle se trouve un véhicule roulant derrière lui.In the examples shown, the image receiver 6 is placed on the dashboard, but it can be placed in any other place visible to the driver,
The camera can also be equipped with a variable focal length arrangement, commonly called "Zoom", the control of which, not shown, can be located on the dashboard, which allows the driver to see the view towards the rear in order to have a better appreciation of the distance at which a vehicle traveling behind it is located.

La caméra peut également être équipée pour la vision de nuit, ce qui permet une utilisation du dispositif à tout moment. The camera can also be equipped for night vision, which allows the device to be used at any time.
