Abstract

The electronic detection and indicator unit makes use of an echo signal (radio or ultrasonic) to monitor the distance to the next vehicle and to detect obstacles while parking. The detector is mounted on the rear of the vehicle, and directs the signal backward to reflect from the following vehicle. The echo signal is processed and if the following vehicle is too close the hazard warning lights or another flashing light is activated. The warning continues until the following vehicle drops back to a safe distance behind. The parking is set to a shorter effective range in response to measurement of vehicle speed. It activates an audible signal for the driver.

Description

I - DESCRIPTION --- La présente invention concerne un dispositif électronique comportant un indicateur lumineux clignotant qui détermine la distance de sécurité à respecter entre les véhicules automobiles en mouvement, et un détecteur d'obstacles sonore facilitant le parcage de ces mêmes véhicules en zone à risques. I - DESCRIPTION --- The present invention relates to an electronic device comprising a flashing light indicator which determines the safety distance to be observed between motor vehicles in motion, and an audible obstacle detector facilitating the parking of these same vehicles in zone to risks.

- Malgré les panneaux de rappel et les marquages au sol sur certaines routes,la distance de sécurité à respecter entre les véhicules en mouvement n'est pratiquement jamais tenue.- Despite the warning signs and the markings on the ground on certain roads, the safety distance to be respected between moving vehicles is almost never maintained.

- Afin de pallier à la carence de certains conducteurs en ce do
maine,il est donc proposé le présent dispositif.- To make up for the deficiency of certain drivers in this area
maine, the present device is therefore proposed.

- L'invention précitée comporte un circuit électronique utilisant un signal d'écho ( hyper-fréquence ,ultrason ou autres ) relié directement au circuit arrière du véhicule ( par exemple aux feux de détresse ) ou à un autre système de feux clignotants placé sur la plage,la lunette ou tout autre endroit sis àl'arrière du véhicule.- The aforementioned invention comprises an electronic circuit using an echo signal (hyper-frequency, ultrasound or other) connected directly to the rear circuit of the vehicle (for example, hazard warning lights) or to another system of flashing lights placed on the range, the telescope or any other place located at the rear of the vehicle.

--- Le processus de fonctionnement est le suivant: Un circuit électronique implanté à l'arrière du véhicule émet un signal d'écho.Ce signal part dudit circuit,touche le véhicule suiveur et revient à sa base de départ où il est analysé.Cette analyse tient compte de la vitesse du véhicule (A) et détermine ainsi la distance de sécurité à respecter par le véhicule suiveur (B).--- The operating process is as follows: An electronic circuit located at the rear of the vehicle sends an echo signal. This signal starts from said circuit, touches the following vehicle and returns to its starting base where it is analyzed. This analysis takes into account the speed of the vehicle (A) and thus determines the safety distance to be observed by the following vehicle (B).

Il n'agit qu'en ligne directe,du centre arrière du véhicule (A) au centre avant du véhicule (B). It acts only in a direct line, from the rear center of the vehicle (A) to the front center of the vehicle (B).

- Par temps de pluie ou de brouillard,la distance de sécurité à respecter est automatiquement adaptée aux conditions atmosphériques.- In rain or fog, the safety distance to be respected is automatically adapted to atmospheric conditions.

- Le système lumineux clignotant entre en action dès que le véhicule suiveur pénètre à l'intérieur de la distance de sécurité à respecter. il reste opérationnel tant que le véhicule suiveur se maintient à l'intérieur de cette zone.- The flashing light system comes into action as soon as the following vehicle enters the safety distance to be observed. it remains operational as long as the following vehicle remains inside this zone.

- Le conducteur du véhicule (A) ne subit aucune contrainte,puisque seul le système lumineux clignotant placé à l'arrière de son véhicule s'allume.Dece fait,le conducteur (s) perçoitaussitôt parfaitement ce signal qu'il déclenche lui-même en entrant à l'intérieur de la distance de sécurité à respecter.Il lui appartient de ralentir pour rester en dehors de cette zone ou alors d'effectuer un dépassement,ce qui fait cesser immédiatement le signal lumineux. - The driver of the vehicle (A) is not subjected to any constraint, since only the flashing light system placed at the rear of his vehicle lights up. when entering within the safety distance to be respected. It is up to him to slow down to stay outside this zone or to overtake, which immediately stops the light signal.

--- L'implantation de ce dispositif n'affecte aucunement la bonne marche des feux arrière ou avant du véhicule.Cet appareil s'adapte à tous les véhicules automobiles (v.L. P.L. camionnettes ou autobus).--- The installation of this device does not affect the smooth running of the rear or front lights of the vehicle. This device adapts to all motor vehicles (v.L. P.L. vans or buses).

- Ce système électronique offre l'avantage d'alerter immédiatement le conducteur du véhicule suiveur qui devra modérer son
allure ou dépasser.- This electronic system offers the advantage of immediately alerting the driver of the following vehicle who will have to moderate his
pace or overtake.

- Lors d'intempéries,ce signal d'écho s'adaptant aux circonstances atmosphériques, sera un atout majeur dans la prévention des accidents par carambolages successifs.- During bad weather, this echo signal adapting to atmospheric circumstances, will be a major asset in the prevention of accidents by successive pileup.

--- Partant du même circuit électronique,un détecteur d'obstacles sonore,ayant des contacts à l'avant et à l'arrière du véhicule, permet son parcage aisé en zone à risques (créneaux entre véhicules, fond de garage,arbre ou poteau isolé sur une place,etc...). --- Starting from the same electronic circuit, a sound obstacle detector, having contacts at the front and rear of the vehicle, allows its easy parking in risk areas (slots between vehicles, garage floor, tree or isolated post on a square, etc ...).

- Ce dispositif émet également un signal d'écho dont la distance d'utilité sera préréglée ou réglable.Ainsi par exemple,la distance de déclenchement du signal sonore à 50 cm d'un obstacle, permet au conducteur de se rendre compte immédiatement de la distance de l'avant ou de l'arrière de son véhicule par rapport à celui-ci.- This device also emits an echo signal, the useful distance of which will be preset or adjustable. For example, the distance from which the sound signal is triggered 50 cm from an obstacle, allows the driver to immediately realize the distance from the front or rear of his vehicle in relation to it.

Ceci lui permet soit de rectifier son approche,soit de pouvoir avancer ou reculer encore un peu.This allows him either to correct his approach, or to be able to move forward or backward a little more.

- En marche avant,ce détecteur d'obstacles agira lors du passage en première vitesse ou à une allure similaire, selon qu'il sera relié à la boîte de vitesses ou au compteur de vitesse.De même, il sera opérationnel,dès le passage de la marche arrière.- In forward gear, this obstacle detector will act when changing into first gear or at a similar speed, depending on whether it is connected to the gearbox or the speedometer. Likewise, it will be operational as soon as it is shifted reverse gear.

- En avançant ou en reculant,le freinage annulera aussitôt le signal sonore.- When moving forward or backward, braking will immediately cancel the audible signal.

- En marche avant,dès le passage en deuxième vitesse,ou à une allure déterminée, l'indicateur lumineux clignotant appréciant la distance de sécurité à respecter entre les véhicules en mouvement,prend le relais. - In forward gear, as soon as you shift into second gear, or at a specific speed, the flashing light indicator appreciating the safety distance to be respected between moving vehicles, takes over.
