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 comprising an automatic control of the low beam or high beam of the vehicle depending on the lighting 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. The highway code required when, at night, two vehicles meet, only the headlights are on. 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 transition from high beam to low beam is left to the driver and depends primarily on his reflexes and his ability to appreciate the inconvenience that these beam can cause a road user traveling in opposite directions.

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. In addition, the safety of driving means that from the cross made, the driver has the maximum lighting for cover as fast visibility of its path despite the inevitable glare created the headlights he just crossing. 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. The reactivation of the beam after crossing also depends on factors that are specific to the driver and it can act either too early which case the user discomfort to the contrary, too late, and in this case, there is a blind outstanding moment 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 seeks to remedy those drawbacks that take to each driver capabilities, by providing a control device support these crossing and beam reacts to the existing lighting 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 invention thus relates to an automatic control device of the lighting circuit of a motor vehicle comprising main beam, dipped beam and a changing switch of the selective feeding of these fires and low beam lights, which includes a control circuit of this switch with at least one brightness sensor prevailing outside and to the front of the vehicle, this detector emits when the brightness is greater than a determined threshold, a toggle signal and holding the switch in its supply position of the dipped beam.

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 into the lighting circuit of the vehicle in parallel with a conventional manually-controlled switch, a rocker selective isolation of one and the other of the switches relative to the power source can be controlled manually by the driver.

D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après d'un mode de réalisation. Other features and advantages of the invention will be apparent 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 is made to the accompanying 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. This diagram shows a vehicle 1 equipped with lights 2 and 3, which have in a known manner dipped beam and main beam. 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. These lights are connected to a power source 4 via a circuit 5 for selectively supplying the low beam and the high beam, by means of a switch 6. Thus from this switch 6, the line 7 is the supply line of the low beam and the line 8 the supply line of the beam.

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. The switch 6 is a switch controlled by a logic device and represented by block 9. The block 9 receives at its input a signal 10 transmitted 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 light energy that frontally receives this vehicle. 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 signal it delivers is proportional to the intensity of the energy and the electronic device 9 containing a target or threshold value, emits towards the switch 6 a signal, or more generally a latch control and maintaining this tilted position when and as long as the input signal 10 received is greater than this value threshold.The changeover switch 6 controlled under these conditions is such that it connects the power supply circuit 7 of the low beam to the source of energy 4. If the light intensity received by the sensors 11 weakens, the signal 10 passes beneath the threshold and the device 9 stops transmitting its control signal and failover maintenance of the switch 6 which returns to a position of rest in which the conductors 8 for supplying the high beam are connected to the power 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. We understand that in these conditions, the passage of the low beam to high beam and back is done in a very fast and very safe, regardless of the driver of the vehicle's capabilities. 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. Naturally the sensors 11 will be accommodated in protected places, such as behind the windshield of the vehicle 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. The brightness sensed by the detectors 11 is first and foremost that emitted by the headlights of vehicles circulating in the opposite direction. Elle peut être également celle ambiante émise par les dispositifs d'éclairage urbain. It may also be that emitted by ambient urban lighting devices. 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. It can be positioned reflectors on roads or highways, including toll barriers of the past, forcing the vehicle to move to low beam to avoid dazzling attendants to these toll stations. 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. Finally, it can be the light diffused by the fog banks through which the beam and is known as the dazzling power is important and dangerous for the driver surprised by such layers of mist.

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. It is however necessary to leave the driver the control of the lighting, as does the device comprises a second switch 12 in parallel to the terminals of the switch 6 and controlled in conventional manner by a member 13 manually operated 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 control device manual high beam and low beam can operate 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 manually controlled by a rocker member 15. This makes the selection between the automatic control by the switch 6 of the lamps and manual control by the 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 above description to be given but on the contrary covers all the variants that may be made thereto without departing from its scope or its spirit.
