Abstract

The system is designed to give a following driver an indication of the braking progression of a vehicle in front. The vehicle is equipped with a brake light whose light intensity is variable. The change in light intensity is actuated by pressure on the brake pedal and is the variation in brake light intensity is a function of braking time. The brake light luminosity increases with braking time. The system may have different coloured brake lights which are timer controlled and which are switched depending upon the elapsed braking pedal action. The braking light control system is coupled to the driving wheels, transmission shaft or universal joints.

D E S C R I P T I O N
La présente invention concerne un dispositif pour les véhicules automobiles et motocyclettes,permettant de délimiter sur route la progression de freinage jusqu a arrêt complet.REPERAGEANT IC OLLISION
DESCRIPTION
The present invention relates to a device for motor vehicles and motorcycles, making it possible to define the progress of braking on the road until it comes to a complete stop.

Traditionnellement,le fait d'appuyer sur la pédale de frein allume les feux rouges à l'arrière du véhicule permettant aux conducteurs qui suivent de manoeuvrer en c or sec n ce. Néanmcins,cette installation ne permet pas au conducteur suivant une voiture sur route d'estimer si la voiture est en début de freinage,en milieu de freinage ou meme à l'arret.Traditionally, depressing the brake pedal turns on the red lights at the rear of the vehicle allowing drivers who follow to maneuver in dry or dry conditions. However, this installation does not allow the driver following a car on the road to estimate whether the car is at the start of braking, in the middle of braking or even when stopped.

Cet état, provoque bien des accidents du fait d'un freinage tardif ou trop violent pour les voitures qui suivent. Le dispositif permet de remédier à ces inconvenients.This state, causes many accidents due to late braking or too violent for the cars that follow. The device makes it possible to remedy these drawbacks.

Il s'agit d'un dispositif à variation on d'intensité lumineuse voire un changement de couleur branché sur la pédale de frein et temporisé qui,en fonction de la durée de freinage modifier2it la luminosité des feux arrieres.It is a device for varying light intensity or even a color change connected to the brake pedal and timed which, depending on the braking time, changes the brightness of the rear lights.

Selon des modes particuliers de réalisation,le dispositif peut au lieu d'une variation de l'intensité lumineuse,être doté d'un double circuit électrique et d'une ampoule de feux d'une couleur différente.According to particular embodiments, the device may, instead of varying the light intensity, be provided with a double electric circuit and a light bulb of a different color.

Lors d'un freinage, la temporisation basculera sur l'autre circuit l'action de la pédale de frein. Le dispositif peut être couplé à l'entrainement des roues, d'un arbre de transmission ou des cardans.When braking, the delay will switch to the other circuit the action of the brake pedal. The device can be coupled to the wheel drive, a drive shaft or cardan shafts.

Dans ce cas,le dispositif indiquera l'arrêt définitif du véhicule.In this case, the device will indicate the permanent stop of the vehicle.

Les variantes peuvent etre montes seules ou conjointement.Variants can be mounted alone or together.

Ce dispositif est particliérement destine aux véhicules à moteurs. This device is particularly intended for motor vehicles.
