Abstract

The lighting device of the vehicle (1) which comprises main-beam lights and dipped-beam lights, includes a commutator (6) for switching the selective supply of these lights controlled by a control circuit (9) which comprises detectors (11), detecting the external luminosity, and pointing towards the front of the vehicle (1), which emit, when this luminosity is higher than a defined threshold, a signal for switching and maintaining the commutator in its dipped-beam light supply position (7).

Description

La présente invention concerne un dispositif d'assistance à la commande d'un circuit d'éclairage d'un véhicule consistant en une commande automatique des feux de croisement ou feux de route de ce véhicule en fonction de l'ambiance lumineuse située à l'avant du véhicule. The present invention relates to a device for assisting the control of a lighting circuit of a vehicle consisting of an automatic control of the dipped or main beam headlamps of this vehicle as a function of the light environment located at the front of the vehicle.

Le code de la route impose lorsque, de nuit, deux véhicules se croisent, que seuls les feux de croisement soient en service. Le passage des feux de route aux feux de croisement est laissé à l'initiative du conducteur et dépend essentiellement de ses réflexes ou de sa faculté à apprécier la gêne que ces feux de route peuvent causer à un usager de la route circulant en sens contraire. The highway code imposes when, at night, two vehicles cross, that only the low beams are in service. The transition from high beam to low beam is left to the driver's initiative and depends essentially on his reflexes or on his ability to appreciate the discomfort that these high beam can cause to a user of the oncoming traffic.

En outre, la sécurité de la conduite veut que, dès le croisement effectué, le conducteur dispose du maximum d'éclairage pour recouvrir au plus vite une bonne visibilité de son trajet malgré l'inévitable éblouissement créé les feux de la voiture qu'il vient de croiser. La remise en service des feux de route après le croisement dépend également de facteurs qui sont propres au conducteur et celle-ci peut intervenir soit trop tôt auquel cas elle gêne l'usager allant en sens contraire, soit trop tard, et dans ce cas, il existe un instant de circulation en aveugle qui peut être dangereux. In addition, driving safety means that, as soon as the crossover is made, the driver has the maximum amount of lighting to cover as quickly as possible good visibility of his journey despite the inevitable glare created by the lights of the car he is coming to cross. The return to service of the main beam after the crossing also depends on factors which are specific to the driver and this can intervene either too early in which case it annoys the user going in the opposite direction, or too late, and in this case, there is an instant of blind traffic which can be dangerous.

La présente invention entend remédier à ces inconvénients qui tiennent aux capacités de chaque conducteur, en proposant un dispositif d'assistance de commande de ces feux de croisement et de route réagissant à la luminosité existante à l'avant du véhicule. The present invention intends to remedy these drawbacks which relate to the capacities of each driver, by proposing a device for assisting the control of these low and high beams reacting to the existing light at the front of the vehicle.

A cet effet, l'invention a donc pour objet un dispositif de commande automatique du circuit d'éclairage d'un véhicule automobile comprenant des feux de route, des feux de croisement et un commutateur de basculement de l'alimentation sélective de ces feux de route et feux de croisement, qui comporte un circuit de commande de ce commutateur pourvu au moins d'un détecteur de la luminosité régnant à l'extérieur et à lavant du véhicule, ce détecteur émettant lorsque cette luminosité est supérieure à un seuil déterminé, un signal de basculement et de maintien du commutateur dans sa position d'alimentation des feux de croisement. To this end, the subject of the invention is therefore an automatic control device for the lighting circuit of a motor vehicle comprising main beam headlights, low beam headlights and a switch for switching the selective supply of these headlights main beam and low beam, which comprises a control circuit for this switch provided with at least one light sensor prevailing outside and at the front of the vehicle, this sensor emitting when this light is above a determined threshold, a signal to switch and keep the switch in its low beam supply position.

Ce dispositif automatique est inséré sur le circuit d'éclairage du véhicule en parallèle avec un commutateur classique commandé manuellement, un basculeur d'isolement sélectif de l'un et l'autre des commutateurs par rapport à la source d'énergie pouvant être commandée manuellement par le conducteur. This automatic device is inserted in the vehicle lighting circuit in parallel with a conventional manually controlled switch, a selective isolation rocker of one and the other of the switches relative to the energy source being able to be manually controlled by the driver.

D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après d'un mode de réalisation. Other characteristics and advantages of the invention will emerge from the description given below of an embodiment.

Il sera fait référence au dessin annexé qui est un schéma du dispositif selon l'invention. Reference will be made to the appended drawing which is a diagram of the device according to the invention.

Ce schéma représente un véhicule 1 équipé de phares 2 et 3, lesquels possèdent de manière connue des feux de croisement et des feux de route. Ces phares sont reliés à une source d'énergie 4 par un circuit 5 permettant d'alimenter sélectivement les feux de croisement et les feux de route, au moyen d'un commutateur 6. Ainsi à partir de ce commutateur 6, la ligne 7 est la ligne d'alimentation des feux de croisement et la ligne 8 la ligne d'alimentation des feux de route. This diagram represents a vehicle 1 equipped with headlights 2 and 3, which in a known manner have low beam and high beam. These headlights are connected to an energy source 4 by a circuit 5 making it possible to selectively supply the dipped beam and main beam headlamps, by means of a switch 6. Thus from this switch 6, the line 7 is the low beam supply line and line 8 the high beam supply line.

Le commutateur 6 est un commutateur commandé par un dispositif logique et représenté par le bloc 9. Le bloc 9 reçoit en entrée un signal 10 émis par un ou plusieurs capteurs photosensibles 11. Ces capteurs 11 sont placés sur le véhicule 1 et orientés de manière à être tournés vers lavant du véhicule pour être sensibles à l'énergie lumineuse que reçoit frontalement ce véhicule. Le signal qu'il délivre est proportionnel à l'intensité de cette énergie et le dispositif électronique 9, contenant une valeur de consigne ou de seuil, émet en direction du commutateur 6 un signal ou plus généralement une commande de bascule et de maintien de cette position basculée lorsque et tant que le signal 10 reçu en entrée est supérieur à cette valeur de seuil.Le basculement du commutateur 6 commandé dans ces conditions est tel qu'il relie le circuit d'alimentation 7 des feux de croisement à la source d'énergie 4. Si l'intensité lumineuse reçue par les capteurs 11 s'affaiblit, le signal 10 passe audessous du seuil et le dispositif 9 cesse d'émettre son signal de commande et de maintien de basculement du commutateur 6 qui revient dans une position de repos dans laquelle les conducteurs 8 d'alimentation des feux de route sont connectés à la source d'énergie 4. The switch 6 is a switch controlled by a logic device and represented by the block 9. The block 9 receives as input a signal 10 emitted by one or more photosensitive sensors 11. These sensors 11 are placed on the vehicle 1 and oriented so as to be turned towards the front of the vehicle to be sensitive to the light energy that this vehicle receives head-on. The signal which it delivers is proportional to the intensity of this energy and the electronic device 9, containing a setpoint or threshold value, transmits towards the switch 6 a signal or more generally a command to toggle and to maintain this tilted position when and as long as the signal 10 received at input is greater than this threshold value. The switching of the switch 6 controlled under these conditions is such that it connects the supply circuit 7 of the low beams to the source of energy 4. If the light intensity received by the sensors 11 becomes weaker, the signal 10 passes below the threshold and the device 9 ceases to transmit its command and switch-over signal for switch 6 which returns to a position of rest in which the main beam feeders 8 are connected to the energy source 4.

On comprend que dans ces conditions, le passage d-es feux de croisement aux feux de route et inversement se fasse de manière très rapide et très sûre, indépendamment des capacités du conducteur du véhicule. Bien entendu les capteurs 11 seront logés à des endroits protégés, comme par exemple derrière le pare-brise du véhicule ou derrière les parois transparentes des phares 2 et 3. It is understood that under these conditions, the transition from low beam to high beam and vice versa is done very quickly and very safely, regardless of the capabilities of the driver of the vehicle. Naturally, the sensors 11 will be housed in protected places, such as behind the vehicle windshield or behind the transparent walls of the headlights 2 and 3.

La luminosité captée par les détecteurs 11 est en tout premier lieu celle émise par les phares des véhicules circulants en sens inverse. Elle peut être également celle ambiante émise par les dispositifs d'éclairage urbain. Elle peut être les réflecteurs disposés sur les routes ou autoroutes, notamment aux barrières de péage de ces dernières, forçant ainsi le véhicule à passer en feux de croisement pour ne pas éblouir les préposés à ces stations de péage. Enfin, elle peut être la lumière diffusée par les nappes de brouillard traversées par les feux de route et dont on sait que le pouvoir éblouissant est important et dangereux pour le conducteur surpris par de telles nappes de brumes. The brightness captured by the detectors 11 is first of all that emitted by the headlights of vehicles traveling in the opposite direction. It can also be the ambient one emitted by urban lighting devices. It can be the reflectors arranged on the roads or motorways, in particular at the toll barriers of the latter, thus forcing the vehicle to pass into low beams so as not to dazzle the employees at these toll stations. Finally, it can be the light scattered by the layers of fog crossed by the high beams and which we know that the dazzling power is important and dangerous for the driver surprised by such layers of fog.

Il est cependant nécessaire de laisser au conducteur la maîtrise de son éclairage, aussi le dispositif comprend-il un second commutateur 12 en parallèle aux bornes du commutateur 6 et commandé de manière classique par un organe 13 actionné manuellement par le conducteur. However, it is necessary to let the driver control his lighting, so the device includes a second switch 12 parallel to the terminals of the switch 6 and conventionally controlled by a member 13 actuated manually by the driver.

La sélection du dispositif automatique de commande ou du dispositif manuel de commande des feux de route et feux de croisement peut s'opérer de nombreuses manières connues. The selection of the automatic control device or of the manual control device for the main and dipped beam headlights can take place in many known ways.

Cette sélection est ici symbolisée par un basculeur 14 commandé manuellement par un organe 15. Ce basculeur effectue la sélection entre la commande automatique par le commutateur 6 des feux et la commande manuelle par le commutateur 12.This selection is here symbolized by a rocker 14 controlled manually by a member 15. This rocker makes the selection between automatic control by switch 6 of the lights and manual control by switch 12.

L'invention n'est pas limitée à la description qui vient d'en être donnée mais couvre au contraire toutes les variantes qui pourraient lui être apportées sans sortir de son cadre ni de son esprit.  The invention is not limited to the description which has just been given but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
