Description
BRAKE LIGHT SYSTEM FOR THE SIGNALLING OF THE BRAKING INTENSITY
OF A VEHICLE"
DESCRIPTION
The present invention relates to a brake light system for the signaling of the braking intensity for vehicles in general, concerning all vehicles categories. This device provides a useful warning about the type of action taken by the vehicle deceleration under braking, therefore indicating the type and braking intensity to drivers of vehicles following behind the braking vehicle.
The present invention is particularly addressed to any kind of vehicles, light or heavy transportation vehicles, motor vehicles or any other means of land transportation, which is provided with "stop lights"
It is known that the braking intensity of a moving vehicle is an indication of how fast the vehicle decelerates until eventually it stops. Hence the obvious need for the driver and especially the following aspects of security, to have a display light of the value of the pressure exerted on the levers or brake pedals through the stop lights of the rear lights. The aim of this is to interpret or "understand" better and well in advance, the situation that it is happening before the driver which follows, thus facilitating the management of the real intentions taken from the vehicle ahead, as the actual behavior and the deceleration of such vehicle, to avoid being hit and/or to hit some others vehicles.
Up to now, and with the purpose of providing this kind of information relevant to braking intensity, different solutions have been proposed. For example, it has been proposed that to a sudden and abrupt braking of a car, the four yellow lights (emergency lights) would light up simultaneously and in addition to the stop lights.
Over the last decade, following the EU directive to place the third additional brake light to the vehicle, it has been proposed by some car manufacturers to set the provision of a dual-stage stop lights, i.e. to a limit braking action corresponds to the lighting of an additional brake light.
Alternatively, it has been proposed by other car manufacturers that in the case of a sudden and hard braking action the rear lights start flashing and as fast as the braking action is, and in order to avoid the risk of collision from the rear.
Further, it has been proposed that some trailers of trucks have their stop lights flashing intermittently and as a result of a braking action.
All these technical solutions, including the simple activation of the stop lights have the disadvantage of not providing to those following the braking vehicle an earlier and accurate indication of the braking action, but rather sometimes tricking the drivers
that follow, because the lighting of the stop lights it is incomplete or too alarming, since it is not possible to understand if the vehicle is stopping, or the driver is simply braking with a high "energy", thus creating misunderstandings, just because of the lack of a full scale of the braking light.
In fact, the proposed solution has the task of "translating" any type of braking into a simultaneously, real, continuous, and progressive "message" from the decelerating vehicle to convert the true intention to the correct interpretation of the subsequent reaction to the vehicle following from the rear, with the result of reducing the time and braking distance.
Therefore, in order to increase the driving safety there is the need to provide information on the actual deceleration of a vehicle to the driver of the vehicle which follows.
The present invention aims to achieve the above described goals by providing a brake light system for the signaling of the braking intensity of a vehicle the system being applied to the stop lights of the latter, which system provides to a driver the opportunity to give information in real time about the real deceleration of the preceding vehicle and through the illustration of the excursion and/or pressure and the release of the brake pedal on the rear light assembly, and through a signaling device that extends and gradually decreases over the entire stop lights surface on every single vehicle rear light assembly.
Thus, the present invention provides a brake light system for the signaling of the braking intensity of a vehicle, just the way it is gradually and continuously modulated, according to appended claims.
The brake light system according to the present invention has some advantageous aspects.
According to a first advantageous aspect, the system improves the perception of noticing the warning light, so it is possible to anticipate the psycho-technical reaction times of and the braking distance to those who follow the braking vehicle, and by having seen the scale light which gradually shows the exact intentions and in real time of the preceding vehicle, thus increasing the driving safety, especially in extreme and adverse conditions while driving.
A second advantageous aspect consists in that the progressive and continuous light scale provides a clear and unambiguous interpretation, rather than the state of the art additional stop lights or the intermittently synchronized lights, just because the system it is much more intuitive for the full modularity of the braking, both when the lights are expanding and decreasing, from the maximum to/from the slightest pressure on the pedal lever, and vice versa, therefore both in active or passive mode.
According to a third advantageous aspect, according to the present manner of lighting of the stop lights results in a better manner of signaling the situation to those who follow the braking vehicle, with even more satisfactory results in terms of stopping distances and interpretation by avoiding sharp reactions of the driver of the vehicle which follows, which often are due to a bad interpretation of the latter on the kind of braking action that the driver of the preceding vehicle has undertook. Therefore, the present system substantially reduces the risk of hit or being hit by other vehicles.
According to a fourth aspect, the present warning light arrangement is most alarming with respect to those of the state of the art, drawing the attention to drivers in limited physical and mental condition (i.e., attention lowered by alcohol, tiredness, etc.), and further in adverse weather conditions, with poor visibility, slippery road surface, etc..
According to a fifth aspect, and especially for heavy vehicles such as lorries, trucks, and coaches, the system results of extremely easy for apply the same with proper stop lights, given the wide rear vertical surface available.
A detailed description a preferred embodiment of one of the unlimited sizes and shapes of the brake light system for the signaling of the braking intensity for vehicles according to the present invention will now be given, not depending upon how the luminous intensity scale moves on the surface of the stop light,' which depends on the design choices of how the optical assembly is mounted at the back of the vehicle, being illustrated herein as an example and without limitation, and with reference to the annexed drawings, wherein:
Figures 1 A to 1 D schematically illustrate a brake light system for the signaling of the braking intensity for vehicles of the present invention and according to different operating conditions thereof;
Figure 2 illustrates a first embodiment of a tail light that incorporates the brake light system for the signaling of the braking intensity for vehicles of the present invention;
Figure 3 shows a second embodiment of a tail light that incorporates the brake light system for the signaling of the braking intensity for vehicles of the present in ention;
Figure 4 shows a third embodiment of a tail light that incorporates the brake light system for the signaling of the braking intensity for vehicles of the present invention;
Figure 5 shows a fourth embodiment of a tail light that incorporates the brake light system for the signaling of the braking intensity for vehicles of the present invention.
Referring now to Figures 1A to 1 D there is shown a brake light system for the signaling of the braking intensity for vehicles according to the present invention.
As can be seen in the figures, there is provided a tail light assembly 1 which typically includes a lighting surface 2 for the signaling of a braking action of the brake pedal of a car.
With particular reference to Figure 1A the lighting surface 2 of the tail light 1 may be either continuous or divided into several different ways and for different areas, for example providing a plurality of areas 3, each of these areas being lighted only on a predetermined position or movement of the brake pedal.
More specifically and according to the present invention, there is provided a transducer device at the brake lever/pedal of the vehicle which detects the position of said brake pedal and sends a corresponding signal to the tail light, which lights up only partially and depending on the position of the brake lever.
For example and as shown in Figure 1 B, at the middle of the full run of the brake lever it will correspond to a simultaneous lighting in a progressive and continuous manner of the stop lights for just half of the available light scale of the surface 2.
Referring to Figure 1C, at an excursion of three quarters of the run of the brake lever it will simultaneously progressively and continuously light up for three quarters of the whole light surface 2 the stop lights or three quarters of all the full "range" available light of the scale.
Finally, and as shown in Figure 1 D, at a maximum excursion of 100% of maximum run of the brake lever it will simultaneously progressively and continuously light the stop light across the whole surface 2 or the whole "range" of the available light of the scale.
Thus, according to the present invention the progressive lighting of the light surface 2 on the tail stop light assembly 1 will indicate in real time how the entire run of the brake lever is increasing and/or decreasing the braking.
Furthermore, and according to the present invention system it can be provided for any type of vehicle an additional control unit with an electronic control for anticipating indication of braking, and to be applied to the present stop light assembly 1 , so that from a given speed on (e.g. 40 km / h) and upon the releasing of the accelerator or throttle pedal, it will be automatically turned on a first light area (i.e. the area 3) of the lighting surface 2 (e.g. 20% of the light scale), resulting in a useful message to give notice of the impending stop, and for a predetermined period of time (e.g. 5 sec), and then turn off automatically if during this period of time a braking action has not been undertaken.
It is good to point out here that this additional feature enhances the concept of
sending a sudden and unequivocal message, finding application thereof uniformly for all types of vehicles and for all the well known effects of collisions.
In this manner it is obtained the effect to alert, to warn, and to anticipate the reaction of those drivers who follow, and also in order to compensate the eventual delay of the signal to the tail lights unit of the vehicle ahead, providing precious moments and greater safety for the travelling vehicles. This anticipating device for the lighting of the braking intensity it is also adapted to all vehicles with automatic transmissions, which do not require a slight release of the throttle pedal when changing gears.
Alternatively, for vehicles with manual shift gear from a determined speed onward, the anticipating lighting device will be appropriately managed by appropriate control units, in order to taking in account a reasonable time period to change gear and/or a significant relative decrease in velocity as a result of the gear shift action and in order not to mislead those who follow.
Therefore, it results in being very useful and especially needed in critical distance, in urban roads, and highways to be duly notified in advance.
With reference now to Figure 2, it is schematically illustrated therein a first embodiment of a tail light 10 of a vehicle, and which incorporates a light system 1 of the present invention.
Typically, the tail light unit 10 has a light region 4, which corresponds to the tail lights, a light region 5, which corresponds to the turning signal yellow lights 5, and a light region 6 corresponding to the reverse light or rear fog light. As can be seen in the figure, according to the present invention, the light system 1 is fully integrated in the tail light unit 10.
Figures 3, 4 and 5 show all different embodiments of an tail light unit 10, incorporating a light system of the present invention. As it can be seen from the figures, during the night time, the system should provide a useful reference to those who follow of the full light scale, for example the latter can be surrounded by tail light 4 (Figure 4). As a matter of facts, it may be advantageous to display the brake light scale within or at a side of the tail light 4 of the same tail light assembly, so as to clearly and detailed understand the full scale of the stop light 1.
During the day, the light scale could be the same area provided for the stop red lights for a single light unit 10.
The LED lights are particularly suitable for this type of signaling.
It is good to note here that according to the present invention, the above explained embodiments of light unit 10 incorporating the light system 1 do not affect the adaptability thereof on already circulating vehicles.
So, it is good to highlight here that the system of the present invention has the following advantageous aspects.
The first aspect is the novelty of signaling the entire braking intensity modulation (complete signaling of the light scale), and indication also of the second stage of the braking, namely relating to the depressing of the braking pedal (full modulation of the braking).
A second aspect is the novelty of a different and more comprehensive system than the previous described so far, but in a more simple and cost-effective manner of providing information on the type of braking to be undertaken, even in the event of having sophisticated electronic devices, i.e. as an automatic adjustment of the distance ACC (Adaptive Cruise Control), or an anti-collision alarm FCW (Forward Collision Warning), not neglecting these devices as a possible alternative or combination with the same, but considering also the present system as a simplest and most reliable against possible troubles on sophisticated electronic systems.
A third aspect is the novelty of introducing a standardized concept of stop lights within tail lights.
A fourth aspect is the novelty of the braking intensity system in being suitable to be coupled to the anticipating system of warning of braking together with displaying of the same stop lights upon the release of the throttle pedal.
In addition, former versions and combinations may also include that the system of the present invention be applied to the optional single third brake light, or only to the tail lights assemblies, just to meet different manufacturing needs of the various models, the number of different existing lights units, ranging from light transportation vehicles up to heavy transportation vehicles.
