FRONT LIGHT SIGNALLING DEVICE IN ROAD VEHICLES OR THE LIKE DESCRIPTION

The present utility model relates to an additional safety element on the front of the vehicle. Such element allows users outside of the vehicle to interpret the driver' s intentions as regards the deceleration thereof and its complete stopping. By vehicle we mean every motor or non-motor means that is allowed, on the basis of current type-approval regulations , to travel on urban or suburban roads or motorways where there are other vehicles or pedestrians.

Currently the motorcycle or motor vehicle or of any other nature, warns other drivers behind about the actions of the driver as regards possible braking. Such information is useful in order to allow following drivers in turn to brake avoiding dangerous collisions.

Currently in the automotive industry such information is completely absent on the front.

With reference thereto some patents and utility models have anticipated the solution relating it to a front light which is activated by the act of braking the vehicle (DE20311594 of 2003, IT0000266543 of 2006, CN201521881 of 2010) , such patents actually claim the activation of the position light or an additional light placed at the front of the vehicle, upon the braking action namely upon the pressure exerted by the driver on the brake pedal .

Moreover in the patents and utility models mentioned lights are added on rearview mirrors to indicate the braking action.

The problems related to such solutions and highlighted by the European standard about vehicle type-approval are mainly two, the one related to a flashing and sometimes blue light, a solution forbidden by the same standard and the possibility that flashing lights placed at the sides of the vehicle where usually turn indicators are placed instead of helping the pedestrian or the driver of another vehicle in front of or arriving from a lateral road, they get the viewer confused by the emergency lights or even worse by the turn indicators. Moreover for the automakers and for their designers this involves a higher stylistic effort directed at finding a solution for positioning such indicators that matches with their style concept.

The coming of daytime running lights and leds pave the way to new solutions such as the one we suggest that uses the same led lights to increase the road safety of the user outside of the vehicle and of the user inside it, the led lights technologically allow the luminous intensity to be increased, thus avoiding the flashing effect, the colour change that would increase as the pressure on the brake pedal increases and the luminous intensity would be a further novelty and safety element (e.g. from white to ice white or light bluish) and it would allow the new invention to be applied just at the daytime running lights, not obliging automakers to new design investments both as regards costs and time.

The fact of providing information to road users, both pedestrians or drivers, about the intentions of braking by the driver is an important information, suffice to say the advantage relating to the pedestrian crossing, or to the fact of having the possibility of understanding at a junction whether another user, arriving from a side by car too, has noted us crossing the road and so whether he/she is braking. Or to allow the driver of a vehicle still at a stop sign or at a traffic light to verify if the driver arriving at the back is braking or not while preparing himself/herself to a possible collision optimizing the consequences of a whiplash.

The so called cervical whiplash is one of the statistically most frequent traumatic events in road accidents and therefore it takes, within the real social disease that is the traumatic pathology due to road accidents, a considerable epidemiological and so economic importance due to the huge repercussion of the costs charged to people, healthcare and to the several forms of public and private social services.

The rachis cervical whiplash is an acceleration- deceleration mechanism transferring energy on the neck that can derive from front or side collisions of motor vehicles. The trauma can lead to injuries of the skeleton or tissues that in turn can lead to several clinical symptoms called Whiplash Associated Disorders.

In Italy every year insurance companies pay, as compensation for the "whiplash", more than two million Euros, leading our country to be at the first place in the world as regards compensations for this "pathology". According to a study by ACI-A IA for 18 accidents out of 100 compensations for permanent damages are required; a percentage considerably higher than Germany (11%), Spain (10%), France (8.7%), United Kingdom (8%) . The most of injuries is due to collisions, that represent 30% of the road accidents with injuries to the drivers for 61% of the cases, to passengers for 30% and finally pedestrians for 9%.

Therefore with reference thereto, the invention offers itself as a safety element inside the vehicle, for the benefit of the driver and outside it for the benefit of road users, the numbers related to the non- safety of them encourage solutions and their applications such to reduce them and the European Economic Community has such target.

Each year around 8000 pedestrians and cyclists lose their life and 300000 are injured in road accidents .

Accidents are particularly frequent in urban areas . Even in case of cars driving at relatively low speeds the injuries caused by a collision with a moving vehicle can be very serious, particularly in the case of impact with the front structures of the vehicle. If the speed is below about 40 km/h, however, it is possible to considerably reduce the severity of injuries by modifying the front part of the vehicles.

The directive sets the safety requirements which have to be met by automakers in order to reduce the severity of the injuries suffered by pedestrians and other vulnerable road users, such as cyclists and motorcyclists, in case of a collision against the front surface of a vehicle.

The Directive is based on Article 95 of the Treaty establishing the European Community. The harmonised technical provisions for the type-approval of motor vehicles, as regards pedestrian protection, are necessary to ensure the proper functioning of the internal market.

The directive relates to the front surfaces of vehicles, namely the bonnet and the bumper.

It applies to motorcars (category Ml) not exceeding 2.5 tons and commercial vehicles (category Nl) not exceeding 2.5 tons derived from Ml category vehicles. It is expected that the Commission will examine the possibility of extending the application scope of the directive to vehicles not exceeding 3.5 tons.

The directive proposes limit values that have to be observed in the construction of the front structures of vehicles and they have not to be exceeded in case of collision between a vehicle and a pedestrian. In order to guarantee them to be observed, the vehicles will be subjected to several safety tests. The tests and limit values are based on recommendations made by the European Enhanced Vehicle-Safety Committee.

Should the limit values be exceeded, the Member States may no longer grant EC type-approvals or registrations for the vehicles concerned.

The technical provisions will enter into force in two stages, for which the directive sets out transitional periods. The provisions for the first stage will have to be met from 1 October 2005 for all new types of vehicles and from 31 December 2012 for all new vehicles. The provisions for the second stage will be compulsory as of 1 September 2010 for all new types of vehicles and from 1 September 2015 for all new vehicles. This transitional period allows manufacturers to comply with the limit values and to incorporate these changes in the picture for the construction of new types of vehicles without having to make immediate changes to vehicles in production.

Given the speed of technological developments in this field, manufacturers may take alternative measures that are at least as effective as those in the directive. Depending on the result of the provided feasibility independent study by 1 July 2004, the Commission will amend the provisions of the directive if necessary.

The European Commission has made it a priority to reduce the number of persons killed and injured on European roads. Its target is to reduce fatal road accidents by 50% by 2010. To this end the European Commission entered into discussions with European, Japanese and Korean motor vehicle manu acturers, which have lead industries to make a pledge to introduce measures aimed at improving pedestrian safety. Following the opinion of the European Parliament and of the Council of Ministers, the Commission drew up a legal instrument establishing the main aims and base technical provisions to be observed and so it offers the necessary legal certainty in this area.

The current standard about colours and functions of the front lights is contained in a European directive 76/756/EEC. Such standard at point three of the attachment I indicates the colours and the types of lights that can be used.

The standard excludes flashing lights, therefore lights that turn on and off, or lights having a colour temperature different than 2854 Kelvin degrees. The European standard provides the national acknowledgment thereof with the possibility of deviating from it in some points. In Italy front lights that are not white are forbidden for daytime, position, high projector and low projector lights and lights that are not ochre or orange are forbidden for turn indicators.

Moreover in the last years automakers have add leds as a front lighting element both for position lights and for daytime running lights of white or ivory light .

Led lights pave the way to new solutions one of which is the object of the present utility model. As described in figures 1, 2 and 3 it is possible to integrate the new solution suggested by this utility model with the lights already provided by the manufacturer (FIG 3) , since the solution according to one embodiment of the present invention is a series of leds 1 combined with daytime running lights that once turned on due to the pressure on the brake pedal by the user, turn on a second row of leds 201, or leds 101 that in the use as daytime running lights are turned off, or simply they increase the luminous intensity of the leds turned on in the daytime running light.

This solution avoids the flashing effect forbidden by the regulations issued by the European Economic Community with regard thereto, it highlights the braking action of the driver and it can indicate the intensity of the braking action relating it to the increasing light.

Moreover the new solution, as already said, harmonizes the design of the front part not obliging designers to obtain new spaces on the car front for the solution suggested by this utility model.

Thus the usual arrangements of direction indicator lights 2, high projectors 4, low projectors 5, fog- guard lights 3 and possible position lights that are not connected to leds but to high projectors 4 remain unchanged. Moreover, in the next future, the light showing the slowing down of the vehicle, by using leds, can be arranged such to change the colour from white or ice white to light bluish or other colours that highlight at a greater extent the braking action by the vehicle driver.

A schematic embodiment of the invention is shown in figure . The block diagram of figure 5 shows an example of the system for carrying out the invention as described above which relates to general means and to general operating units, it being clear for the person skilled in the art the specific constructional configuration of the means and of operating units that are represented in a general manner.

The braking means of the vehicle generally denoted by 10 are connected to transducer sensors generating a control signal related to the braking action or effect exerted. For example as braking means it is possible to indicate the brake pedal and the transducer can be a pedal position or movement sensor and/or as an alternative or in combination a sensor of the pressing action exerted on the brake pedal . A variant can consist in a pressure sensor placed in the braking circuit and which is intended to measure the pressure of the oil hydraulic fluid supplying the brake calipers and generating an electric signal corresponding to the measured pressure.

As an alternative the slowing down effect can be derived from the speedometer of the vehicle for example by taking the electric signal generated by it.

Said means generally denoted by the functional box 11 can be provided also in combination with one another and the braking action and/or effect can be determined on the basis of signals generated by said different means used in combination with one another. The signal or signals of the sensor or sensors are provided to a feeding unit 12 for the feeding signal to the stop front lights 13. In this case, the signal corresponding to the braking action or effect is used by the feeding unit 12 as a control signal for the differentiated activation of the front stop lights 13 according to the modes described above and namely activating the lights to emit a diversified luminous intensity depending on the different braking action and/or different braking effect.

The front light device signalling the braking conditions of the vehicle can be easily made in the form of a kit of parts mountable on an existing vehicle as a post-sale additional equipment. This applies also if the vehicle has not been designed with an arrangement for being equipped with the device according to the invention.

In this case, for example the kit can comprise at least one headlight or the like having means of any type for fastening to the front part of a vehicle. The fastening means can be of any type depending on the manufacturing standards of the vehicles and particularly to those mandatory for their registration. Together with the headlight the kit comprises at least one sensor for the braking action or effect. As sensors it is possible to provide: sensors of the pressing action on the brake pedal that for example can be piezoelectric sensors provided on the brake pedal where the foot of the driver rests or in other suitable points depending on the construction of the braking system; or sensors of the oil hydraulic pressure in the oil hydraulic circuit controlling the calipers; or transducers of the speed signal of the vehicle speedometer in control signals. The sensor or sensors generate control signals that are provided through cables to a control unit that constitutes the feeding unit of the means generating the light signal provided in the headlight. The feeding signal is provided to said means generating the light signal through at least one feeding cable that is part of the kit too. The control unit can be provided with means for fastening in a suitable position for example if there is space in the engine compartment together with the other control units of the vehicle.

As an alternative, at least for the signals of the sensor or sensors the transmission to the feeding control unit by wireless means can be provided.

It has to be noted that the constructional specifications of the kit depend a lot on the type of vehicle to which the kit has to be applied and therefore the specific constructions of the elements forming the kit and that have been described above are the result of a simple adaptation of the inventive concept of the present invention to the different and contingent situations, which adaptation does not lie outside the general knowledge and skills of the person skilled in the art.
