Abstract

The device has a wireless transmitter (C), a wireless receiver (D), and a light and sound alarm (F). The transmitter coupled to a shock detector (A) of an airbag system (B) is connected to a roof antenna (E) of a vehicle. The transmitter sends two types of radio waves of which one wave represents an accident and another wave represents a vehicle breakdown. The receiver is connected to an outlet of the antenna and the alarm.

Description

DescriptionDescription

DISPOSITIF DE SIGNALISATION D'ACCIDENT OU D'OBSTACLE SUR LA CHAUSSEE La présente invention consiste en un dispositif ( schéma 1) monté dans les véhicules automobiles circulant sur la chaussée Il est composé d'un émetteur radio (C), d'un récepteur radio (D), et d'un avertisseur lumineux et sonore (F). Il permet d'avertir, grâce un signal lumineux et sonore placé sur le tableau de bord du véhicule, le conducteur de la présence sur la chaussée d'une voiture accidentée ou en panne. L'émetteur radio (fig.l,C) relié au détecteur de choc du système de coussin gonflable (fig.1, A), ou directement à ce dernier, émet deux types d'ondes radio d'une portée de 500 m. Le premier représente les accidents et est déclenché par le détecteur de choc ou le coussin gonflable automatiquement. Le deuxième représente les pannes et est activé manuellement par pression sur le bouton allumant les feux de détresse. Ces ondes sont captés par tous les véhicules équipés de ce dispositif (fig.l,B), via l'antenne de toit du véhicule (fig.1, E),et le récepteur (fig.1, D) faisant partie du dispositif. The present invention consists of a device (diagram 1) mounted in motor vehicles traveling on the road. It is composed of a radio transmitter (C), a radio receiver. (D), and a light and sound alarm (F). It allows the driver to warn the driver of the presence on the roadway of an accidented or broken down car, using a light and sound signal placed on the vehicle's dashboard. The radio transmitter (fig.l, C) connected to the air bag system shock detector (fig.1, A), or transmits two types of radio waves with a range of 500 m. The first represents accidents and is triggered by the shock sensor or the airbag automatically. The second represents faults and is activated manually by pressing the button lighting the hazard warning lights. These waves are received by all vehicles equipped with this device (fig.l, B), via the vehicle roof antenna (fig.1, E), and the receiver (fig.1, D) forming part of the device .

Les ondes (fig.2,C) reçues se traduisent ensuite en signal lumineux grâce à l'avertisseur lumineux et sonore (fig.l,F). Une lumière rouge indique une voiture accidentée et une orange indique une voiture en panne. The waves (fig. 2, C) received then translate into a light signal thanks to the light and sound horn (fig. L, F). A red light indicates a damaged car and an orange indicates a broken down car.

La fréquence de clignotement des signaux lumineux et sonore, varient en fonction de la distance du véhicule qui émet ces ondes: plus le récepteur est proche de l'émetteur, plus les ondes captés sont fortes et cela augmente la fréquence du signal, permettant au conducteur d'évaluer la distance le séparant du véhicule accidenté ou en panne. Le dispositif prend tout son intérêt, lorsque la voiture accidentée (fig.2,A) est hors du champs visuel du conducteur comme il est présenté sur la figure 2. En étant prévenu a l'avance de la présence d'un véhicule sur la chaussée, le conducteur (fig.2,B) anticipe les manoeuvres d'évitement et cela contribue a la sécurité routière en diminuant les risques de carambolage. The frequency of flashing of light and sound signals, vary depending on the distance from the vehicle that emits these waves: the closer the receiver is to the transmitter, the stronger the waves received and this increases the frequency of the signal, allowing the driver to assess the distance separating it from the damaged or broken down vehicle. The device takes all its interest, when the damaged car (fig.2, A) is out of the driver's visual field as it is presented on figure 2. By being warned in advance of the presence of a vehicle on the pavement, the driver (fig. 2, B) anticipates avoidance maneuvers and this contributes to road safety by reducing the risk of pileup.

Claims

Claims l. Device characterized in that it is composed of a radio transmitter (fig. L, C), a radio receiver (fig. 1, D) and a light and sound warning device (fig.l , F).

2. Device according to claim 1 characterized in that the transmitter is connected to the airbag (airbag) (fig.l, B), or to its shock detector (fig.l, A), and also, connected on the vehicle roof antenna (fig.l, E).

3. Device according to claim 1 or 2 characterized in that the transmitter sends several types of waves each of which represents either an accident, a failure to any other information.

4. Device according to claim 1 characterized in that the receiver is connected to the socket of the vehicle roof antenna and any light and / or audible warning of the vehicle.

6.The device can be a box which is placed anywhere in the passenger compartment of the vehicle, or can be integrated into an already existing device, such as the car radio.

8.The frequency of the flashing of the light or sound signal varies according to the distance separating the emitting device and the receiving device, the latter being sensitive to the variation in power of the waves as a function of this distance.

9.The device is powered by the vehicle battery or by a battery if it is carried by a human being.
