The invention relates to a dynamic signaling system of the evolution of the braking maneuver that has visual proportionality with respect to the loss of speed of the vehicle, with fixed or programmed response sensitivity of the system in each braking maneuver, which enables visual proportionality and dynamic unambiguous representation of the variation of speed of the vehicle during braking. It can be applied with advantages to any type of vehicle, with an electric or hybrid combustion engine, with manual or automatic transmission. The system can be applied to both brake lights and the third brake light (high-mount brake light) indistinctly or jointly, further reinforcing the dynamic effect of attention and the transmission of information.

Since Florence A. Bridgwood, in the early twentieth century, invented the first braking signal (stop sign that appears when you press the brake pedal), this indication has evolved to the current brake lights, which, after more than a century, do not do more than indicate the same as then "that the driver has depressed the brake pedal of your vehicle." As the speed of the vehicles and the quality of the roads have been increasing, this information is becoming increasingly insufficient, since the reaction times of the driver, faced with a braking maneuver, have drastically shortened. Subsequently, to reduce this reaction time, the third brake light (or brake light on raised) appeared to shorten the warning time of "driver pressing the brake pedal of your vehicle", since this third brake light allows (in some cases) be seen through the rear window of the vehicles that precede us, thus shortening the reaction times. Although it has been shown that the third brake light does not reduce accidents by more than 5%, it must be borne in mind that, currently, installing a third brake light is quite cheap and that although it only reduces collisions by a small percentage Everything is profitable if you avoid accidents. Another advance, more than a century later, have been the indicators of emergency braking. The lack of attention of the driver during the driving and the unexpected events, responsible for a multitude of accidents, are tried to alleviate by the use of high intensity LEDs and / or by the blinking or increased intensity emitted by the brake lights (indicators of emergency braking) but, to date, the studies conducted in vehicles circulating have not shown any significant improvement and if it has been observed that, in the long run, they will produce, especially in short distances, damage in the sight of other drivers and, in any case, the emergency indication almost always occurs when it is no longer possible to avoid the accident. The last advance, in the 21st century, are the radars and sensors installed in the front of the vehicles, which defend (only the vehicles that incorporate them) from frontal impact (with a pedestrian, an obstacle or another vehicle) but they can not avoid the rear reach of the vehicles that follow them (unless they incorporate the same system) and their reliability, at 100%, is currently very questionable. The real efficiency of these systems will come when all the vehicles in the world can incorporate, in the front zone, these systems and also be redundant or with some other formula that increases their reliability. That moment is too far for economic cost and unresolved problems, which means, during this time, a number of accidents with injuries and / or loss of life, that is, a very high social and economic cost. In addition, all these systems also leave other issues unresolved: 1a.- When the sunlight falls on the catadioptrics of the brake lights of a vehicle, the reflection makes it appear that the pilot is illuminated, although it is not really so, generating disinformation in the other drivers. This phenomenon never occurs when the illuminated surface varies with the loss of speed, since the areas that illuminate are easily distinguished from those that are reflecting the ambient light. 2a.- The perception of the human being, with respect to the speed of his vehicle, is based on the sensitivity of the body to the forces of inertia (very subjective) and mainly in the variation of the relative position of his vehicle with respect to the environment . In case of fog, rain, dust, snow, etc. the perception of the relative variation with respect to the environment diminishes enormously which, very often, gives rise to accidents by chain reaches, with many drivers involved and the consequent injuries in the users and economic costs. The present invention does not present this problem as it minimizes the need for external references. 3a.- The joint flashing of emergency lights of several vehicles can result in a high frequency of high value that can be harmful to health, generating discomfort and even epileptic attacks in sensitive people. 4a.- The mentioned systems, in case of failure, cause the accident that they try to avoid. In the present invention this does not occur, since, in the absence of signal, the proportional dynamic brake indication system functions as a conventional brake light (zero signal equal to the entire illuminated surface). The patents and utility models are known that, using decelerometers, mechanisms in the brake pedal, the pressure of the hydraulic circuit of the brakes, frontal radars, etc. increase the intensity emitted by the brake lights or vary their shape, trigger emergency braking indications with flares of the brake lights, or turning on the warning, when the brake pedal stroke, brake system pressure, deceleration or the distance / speed ratio exceeds a preset value, such as: US6163256, CN2302166, US2017028906, UA60311, US5610578, DE102013002308, TW201100280, KR20140129592, and others. Almost all of them are only visible and understandable from short distances. Its visibility and effectiveness depends largely on the environmental conditions are not adverse (fog, snow, rain, dust, etc.) and some of them depend on the characteristics of the vehicle, even at every moment. All these patents and utility models must be adapted to each particular vehicle or add elements for its operation. The present invention does not present these problems and minimizes the need for external references.
