Abstract

The invention relates to an assembly for detecting a blind spot for a motor vehicle. The assembly according to the invention is characterised in that it comprises, for each vehicle 2, 4, an infrared emitter 1 placed at the front and on the offside, the said emitter 1 permanently sending out, when the vehicle 2 moves along, a narrow beam 7 consisting of a set of infrared pulses, and an infrared receiver 3 located on the nearside of the vehicle 4, the said receiver 3 being connected to a light and/or acoustic signal generator inside the passenger compartment which is powered when the said receiver 3 receives pulses coming from the emitter 1 of another vehicle 2. Application to the motor industry.

Description

ENSEMBLE DE DETECTION D'ANGLE MORT POUR VEHICULES
AUTOMOBILES
L'invention concerne un ensemble de détection d'angle mort pour véhicules automobiles.ANGLE DETECTION ASSEMBLY FOR VEHICLES
AUTOMOBILES
The invention relates to a blind spot detection assembly for motor vehicles.

L'angle mort, c'est-à-dire l'angle dans lequel un ve- hicule en cours de dépassement n'est pas visible par le conducteur du véhicule dépasse, dans son ou ses retroviseurs, est la cause de nombreux accidents en traSnant des pertes de vies humaines et, dans tous les cas, de dépenses élevées. Ce defaut est parti culiérement grave pour les véhicules volumineux tels que poids lourds et vehicules de transport en commun.The blind spot, that is to say the angle in which a vehicle in the process of passing is not visible by the driver of the vehicle exceeds, in his or her mirrors, is the cause of many accidents in resulting in loss of life and, in any case, high expenditure. This defect is particularly serious for bulky vehicles such as heavy goods vehicles and public transport vehicles.

Diverses propositions ont ete faites pour diminuer ou annuler l'angle mort, en particulier des systemes periscopiques et des systèmes utilisant une caméra de télévision et un récepteur de télévision.Various proposals have been made to reduce or cancel the blind spot, in particular periscopic systems and systems using a television camera and a television receiver.

Ces systèmes, qui sont souvent d'un prix de revient tres élevé, présentent en outre l t inconvenient de ne pas informer systématiquement le conducteur qu'il est en train d'être depassé, de sorte que ce conducteur devrait théoriquement consulter sans arrêt ses retroviseurs, qu'ils soient traditionnels ou plus sophistiqués.These systems, which are often very high cost, also have the drawback of not systematically informing the driver that he is being passed, so that this driver should theoretically constantly consult his mirrors , whether traditional or more sophisticated.

La présente invention vise à supprimer ces inconvénients des retroviseurs et dispositifs connus grâce à un ensemble actif signalant automatiquement au conducteur d'un véhicule qu'il est en train d'être depassé.The present invention aims to eliminate these drawbacks of known mirrors and devices by means of an active assembly automatically signaling to the driver of a vehicle that he is being exceeded.

A cet effet, l'ensemble selon l'invention est caracterise par le fait qu'il comprend, pour chaque véhicule, un émetteur infrarouge place à l'avant et du côté de la route ou se fait la circulation, ledit émetteur envoyant en permanence, quand le véhicule se deplace, un faisceau étroit constitué d'un train-d'impulsions infrarouges, et un récepteur infrarouge disposé sur le côté du véhicule opposé au côté de la route ou se fait la circulation,ledit récepteur étant relié à un générateur de signaux lumineux et/ou sonores à 1 'inté- rieur de l'habitacle qui est alimenté lorsque ledit récepteur reçoit des impulsions provenant de l'émetteur d'un autre véhicule.To this end, the assembly according to the invention is characterized by the fact that it comprises, for each vehicle, an infrared transmitter placed at the front and on the side of the road where traffic is circulated, said transmitter permanently sending , when the vehicle is moving, a narrow beam consisting of an infrared pulse train, and an infrared receiver arranged on the side of the vehicle opposite to the side of the road or traffic, said receiver being connected to a generator light and / or sound signals inside the passenger compartment which is supplied when said receiver receives pulses from the transmitter of another vehicle.

Selon une forme de réalisation de l'invention, 1 'émet- teur infrarouge est logé au voisinage du projecteur correspondant. En variante, il est monte sur le côté correspondant du véhicule.According to one embodiment of the invention, the infrared emitter is housed in the vicinity of the corresponding projector. Alternatively, it is mounted on the corresponding side of the vehicle.

De preference, le récepteur infrarouge est place au voisinage du rétroviseur extérieur correspondant. En variante, il est porte par le côté correspondant du véhicule.Preferably, the infrared receiver is placed in the vicinity of the corresponding exterior mirror. Alternatively, it is carried by the corresponding side of the vehicle.

Selon une forme de réalisation avantageuse, le récepteur infrarouge est en veille en marche normale et est éveillé par la réception d'impulsions provenant de l'émetteur d'un autre véhicule.According to an advantageous embodiment, the infrared receiver is in standby during normal operation and is awakened by the reception of pulses coming from the transmitter of another vehicle.

On va decrire l'invention à l'aide du dessin annexé dont la figure unique est un schéma de principe illustrant le fonctionnement entre deux vehicules d'un ensemble selon un exemple de réalisation de 1 'inven- tion.The invention will be described with the aid of the appended drawing, the single figure of which is a block diagram illustrating the operation between two vehicles of an assembly according to an exemplary embodiment of the invention.

Chaque vehicule comporte un emetteur infrarouge 1 qui n'est represente au dessin que sur le vehicule 2 en cours de dépassement, et un récepteur infrarouge 3 qui ne figure dans le dessin que sur le véhicule 4 qui va être dépassé.Each vehicle includes an infrared transmitter 1 which is only shown in the drawing on the vehicle 2 being passed, and an infrared receiver 3 which is shown in the drawing only on the vehicle 4 which is going to be passed.

L'emetteur infrarouge 1 est logé à l'avant droit du véhicule 2, au voisinage du projecteur 5. Le récepteur 3 est logé dans le support du rétroviseur de droite 6 du vehicule 4. Bien entendu, pour les pays là conduite à droite, la disposition doit être inversée ou, de préférence, on prévoit un émetteur 1 et un récepteur 3 de chaque côté du vehicule. The infrared emitter 1 is housed at the right front of the vehicle 2, in the vicinity of the headlight 5. The receiver 3 is housed in the support for the right-hand rear view mirror 6 of the vehicle 4. Of course, for countries there driving on the right, the arrangement must be reversed or, preferably, a transmitter 1 and a receiver 3 are provided on each side of the vehicle.

L'émetteur infrarouge 5 envoie en permanence vers l'avant un faisceau etroit 7 constitue d'emissions impulsionnelles de rayonnement infrarouge, lorsque le vehicule 2 est en fonctionnement. Le recepteur 6 est en veille lorsque le vehicule 4 est en fonctionnement et est éveillé par les premières impulsions du faisceau 7 qu'il reçoit. Le récepteurS commande alors l'alimentation d'un dispositif de.signalisation acoustique et/ou optique (non représenté)- logé dans l'habi- tacle du vehicule 4, dont le con-ducteur est ainsi automatiquement averti qu'il va être dépassé. The infrared emitter 5 permanently sends a narrow beam 7 forward which constitutes pulsed infrared radiation when the vehicle 2 is in operation. The receiver 6 is on standby when the vehicle 4 is in operation and is awakened by the first pulses of the beam 7 which it receives. The receiver then controls the supply of an acoustic and / or optical signaling device (not shown) - housed in the passenger compartment of the vehicle 4, the driver of which is thus automatically warned that it will be exceeded. .
