FR2659610A1 - Braking intensity indicator (warning device) for motor vehicles - Google Patents

Abstract

Braking intensity indicator for any motor vehicles, abbreviated to "B.I.I.". The invention relates to a device making it possible immediately to inform the driver of the following vehicle of the intensity of the braking applied on a motor vehicle in traffic. It consists of sensing of the braking pressure in the brake circuit, transmitted using various relays to two horizontal lighting strips situated at the rear of the motor vehicle, which may replace the conventional "brake (stop)" lights. These two strips are illuminated progressively towards the centre until they form a single red luminous band over the entire width of the vehicle at the rear, in the event of maximum braking. The device tends to improve road safety by avoiding the seconds of hesitation for knowing whether or not the vehicle in front is braking sharply.

Description

 The present invention relates to a braking intensity warning for all motor vehicles, denoted in abbreviation: "A.I.F.".

 In a line of vehicles sometimes traveling at high speed on motorways, for example, it is difficult to know immediately the braking intensity of the vehicle in front, when the "STOP" braking lights are switched on.

 The second or seconds of hesitation are often missing in the finishing of the following vehicle and are therefore fatal.

 The present invention therefore consists in installing on vehicles, a device making it possible to instantly inform the driver of the following vehicle, that an intensive braking is carried out following an incident, a danger or 'an accident.

 The principle consists of a progressive ignition at the rear of the vehicles, of two horizontal red ribbons1 according to the intensity of the braking.

 Thus, simple braking makes it possible to switch on the usual "stop" lamps signaling the braking and starting point of the 2 ramps. As soon as braking becomes significant, the two horizontal ramps gradually stallurn according to the intensity of braking from the 2 "stop" lamps and meeting towards the center.

 So a driver who sees two red ramps suddenly light up at the rear of the vehicle in front is immediately informed that the vehicle is in full braking. The half-lit ramps indicate heavy braking, barely lit slight braking.

 Another advantage of this principle: in addition to immediate information, it is to alert the vigilance of a driver who quickly gets used to the routine of "stop" lights of the vehicle preceding it in an unbroken line of cars on a long journey.

 The principle is based on capturing the braking intensity, either from the stroke of the brake pedal, or more efficiently and more reliably from the pressure of the brake fluid exerted inside the circuit. braking.

 This pressure can be captured for example from the brake distribution master cylinder or inside the individual brake circuit of each wheel.

 The information on the pressure sensed by a manometer or any other system will be transmitted to a relay capable of transforming the variation of pressure into variation of intensity of an electric current.

 This inforrratiorj amplified by "TRIAC" transistors or any other system will make it possible to supply either a series of electro-luminous diodes, incessant "LEDs", or a series of conventional light bulbs in vehicles, or finally a system of optical fibers, the ures or the others being located inside the two rarapes, themselves covered with a translucent or transparent plastic cover of red color, the whole being located at the rear of the vehicle horizontally at the level of the usual "STOP" lights.

 The dimensions of the raes, length and width can be a function of several parameters: either according to the vehicle models or can be standardized in a French or European standard if the invention becomes compulsory on all vehicles1 in order to improve the security. The ramps can join in the center or not.
