    Interactive system between traffic signs and vehicles.
    5 OBJECT OF THE INVENTION
    The present invention relates to an interactive system in which traffic signals and vehicles interact for better information on such traffic signals, for better vehicle speed control and to improve road safety in drivers in
    10 general, and, mainly, with respect to those drivers who could have diminished some of their sensory faculties, due to their age or due to some physical defect, such as deafness.
    BACKGROUND IN THE STATE OF THE TECHNIQUE
    15 In the current driving speed limits are summarized to visual traffic signals. There are moments of driving in which for various reasons -by saturation of the signals, or by the constant changes of signals at crossings or curves, or by overtaking large vehicles that impede our vision-, the user does not know
    20 really the information or prohibitions that indicate the signals or make you doubt, which triggers a significant number of accidents. This also implies that a very important part of driving attention is to control the constant changes of the traffic signals, which makes losing attention to other fundamental driving circumstances and that are essential for driving.
    25 responsible for motor vehicles and greater road safety (cases of blindness due to lack of attention, blindness to change due to visual interruption, or others). The user is so aware of the signs that sometimes he does not see other vehicles or pedestrians. The repressive fear of traffic sanctions also plays an important role in over-attention to speed limits, to the detriment of other circumstances.
    30 There are currently a very high number of drivers over 65 years of age, approximately 15%, calculating that in a few years this percentage will increase to 30%. There are also a significant number of people with diminished physical abilities, such as deaf, lacking visual acuity, or others. These people need
    35 an aid since they have their physical faculties generally diminished. In respect of


    users with a lack of visual acuity, currently studying the largest traffic signs, but this would be a high cost.
    There are security systems such as the one used by the Ministry of Development of the Government of Spain for the maintenance of the roads, in which a car equipped with the system travels the roads detecting the signals, recognizing them and relating them to their geographical positioning (GPS), and in which, therefore, it has adapted to the recognition of signals for vehicles. This system has the disadvantage that it needs time to update, while with the emitter system of an infrared or radiofrequency signal proposed with the present invention, at the time of its placement, because it is provisional, works, accidents, or other characteristics , can immediately be read by the vehicles in its path.
    Other types of vehicles with traffic signal detection systems are high-end and very limited for economic reasons. They also have the disadvantage that in all countries traffic signs are not standardized and their homogenization would be expensive. Since there is the possibility of coupling it to the existing signals in a cheap way, it would allow their universalization if their manufacturing were normalized.
    Given these drawbacks, the present invention assists the user with verbal information, which the system will transmit through an electronic device, which will transform the infrared or radiofrequency signal into a spoken message, or even for people who have impaired hearing acuity (hearing impaired ), within reasonable limits, may be transmitted to a hearing aid or headset that will facilitate hearing.
    The system developed here allows, therefore, and compared to the previously known, that with a small cheap device and easily placed in the vehicle, any vehicle of any range, variety, age, can be equipped, which makes it more universal.
    With this system, the user should only look at the indicator screen and observe, quickly and easily, what is the speed limit along the route that he is traveling, at the same time he will be listening, in verbal message, the content of Warning signs, prohibition or information.
    Similarly, if the vehicle consists of operating systems necessary to use the infrared or radiofrequency signal referred to in the proposed system,


    automatically, its speed will be regulated, making driving safer, since the speed control will be automatic and will allow the driver's attention to control other essential requirements, such as safety distances, controlling rearview mirrors in overtaking, be aware of the vehicles that precede or precede it, the presence of pedestrians, foreign objects, and all the necessary precautions for safe driving.
    In sum, the present invention, as opposed to the foregoing, and since it consists of an interactive system between the traffic signals and the vehicle, facilitates better information of such traffic signals, speed control and, grants greater road safety to people who, because they are older, have reduced physical abilities. It also allows more information, since the traffic signals, at the same time that they inform visually, send an infrared or radiofrequency signal that picks up a screen that visually and verbally informs the driver of the traffic signals at the precise moment , even if you have not noticed the limitation due to carelessness, due to the visual obstruction of the signal by another vehicle, visual limitations in night traffic, lack of visual acuity of the driver, or for any other cause. In this way, it is avoided that there are moments in which there are doubts or the content or existence, in real time, of the prohibitions or information prescribed by traffic signs is really unknown.
    EXPLANATION OF THE INVENTION
    The proposed interactive system between traffic signals and vehicles, for better information to the user, vehicle speed control and for road safety in drivers in general, and especially with those who could have diminished some of their sensory faculties due to their age or due to some physical defect (such as deafness), it is characterized in that the infrared or radiofrequency signal received from the transmitter is transformed, through a receiver integrated in the CAN-BUS (acronym for the English Controller Area Network, which is a protocol of communications developed by the German firm Robert Bosch GmbH, based on a bus topology for the transmission of messages in distributed environments, and which also offers a solution to the management of communication between multiple CPUs (central processing units) of the vehicle, in an order that, through a software installed in the vehicles, goes to the motor control unit, which carries i Implemented a speed regulation-limitation system and makes it automatically adapt to the speed indicated by the traffic signal.


    Thus, the proposed system consists of three fundamentally elements:
    1. A transmitter with a photovoltaic power system or through a network, 5 coupled to the traffic signal.
    2. An infrared or radio frequency signal receiver that can be the same radio antenna as the vehicle.
    10 3. An attached external device that visually and audibly informs the information received from the traffic signal.
    The software implemented in the vehicle's computer will adapt its speed to the one received from the traffic signal.
    15 On the one hand, the infrared or radiofrequency signal emitter placed in the traffic signals emits information, and a receiver in the vehicle receives it and transforms it into information inside the vehicle, in a place of easy vision for the driver and at the same time in spoken (auditory) and image (visual) information.
    20 On the other hand, the receiver integrated in the CAN-BUS of the vehicle, sends an order that goes to the motor unit of the vehicle, which has implemented the system of regulation-speed limitation, which causes the engine to adapt automatically to it, so that the vehicle adapts to the infrared or radiofrequency signal that goes
    25 receiving traffic signals.
    The vehicle incorporates two sources of information for the speed system: one from the driving position (which many vehicles carry) and another from the receiver of the information transmitted by the traffic signals. In either one
    30 cases the behavior of the vehicle is the same: the vehicle responds to the accelerator provided that the speed it develops is lower than the one set by the limiter (either the one set by the driver or the one arriving from the limiting signal).
    The interactive system is therefore composed of a simple set of sender and receiver,
    35 indicating the traffic speed signaling, confirming its perception by intermittent audible signals of gradual frequency or intensity, at the same time as the indication


    graphic of the signal (image) by means of flashes on the display, said signal remaining for a certain time. In turn, this information will be received by the vehicle speed control, which will act on its speed, as indicated by the traffic signal.
    The “display” display screen visually indicates the desired signaling (traffic signal) captured from a particular transmitter placed in the traffic lane. The traffic signal with the determined speed is displayed for a certain preset time, so that the driver can notice it, in the same way that the vehicle speed controller performs the appropriate maneuvers to condition the vehicle speed to the of the signal received from sound emission (acoustic or spoken), which warns about the signal received with the idea of previously capturing the driver's attention.
    If the vehicle is not included with a screen in which to visualize the information, alternatively, an external screen will be included, coupled in a place suitable for easy viewing and hearing in the dashboard, additionally incorporating, in both cases, a small speaker.
    Alternately, a spoken message is received by a hearing aid. Thus, in some cases, the location of the emitter's signal in the sirens of the emergency vehicles (firefighters, ambulances, police) is foreseen, being received by the indicated hearing aid, which will make the hearing impaired, aware of the presence of These vehicles without the need to notice only, visually.
    Alternatively, the display of the signal on a mobile phone that receives an MSM data message is provided. The signal, in this case, emits at the same time an MSM, data message, which the user's mobile phone receives, to translate it into a graphic message on the mobile phone screen and a spoken message with the content of the limitation of the signal.

    one. Transmitter.

    EXAMPLE OF PREFERRED EMBODIMENT
    25 The interactive system between traffic signals and vehicles consists of three fundamental elements.
    1. An emitter (1) with a photovoltaic power system or through a network,
    although for reasons of costs it is recommended with power through 30 photovoltaic panels, coupled to the traffic signal.
    2. A receiver (2) of the infrared or radiofrequency signal that can be the same radio antenna of the vehicle.


    3. Display screen (3) coupled to the vehicle, which visually and audibly informs the information received from the traffic signal.
    A software implemented in the vehicle's computer adapts its speed to the5 received from the traffic signal.
    The interactive system is thus composed of a simple set of transmitter (1) and receiver (2), which indicates the traffic speed signaling, confirming its perception by intermittent sound signals of gradual frequency or intensity, at the same time as the indication
    10 signal graph (image) by means of flashes on the display screen (3), said signal remaining for a certain time. In turn, this information will be received by the vehicle speed control, which will act on the speed of the vehicle, as indicated by the traffic signal.
    15 The emitter (1) consists of a small hermetic, waterproof case of weather-resistant material, with a simple integrated circuit capable of emitting infrared or radiofrequency signals. In both cases the signal types are coded, one for each type of traffic signal and reserved for this use. The emitters installed in the traffic signals are powered by long-lasting batteries and by current and / or plates
    20 lots.
    The receiver (2), consists of any of those already existing in the market, by means of its corresponding decoder, which upon receiving the infrared or radiofrequency signal of the transmitter, would transmit to a display screen "display" (3), in which it is displayed
    25 graphically the desired signal that would correspond to a specific and specific emission code. The receiver (2) also includes a sound emission system (acoustic or spoken), which warns about the signal received with the idea of previously capturing the driver's attention.
    30 The “display” display screen (3) is determined by the vehicle's own on-board computer screen, by means of an auxiliary screen or by means of the mobile phone's own screen (7) that has a special application of software, only designed for this purpose. Its objective is to visually indicate the desired signaling (traffic signal) captured from a given transmitter placed in the
    35 road. The traffic signal with the determined speed is displayed for a certain preset time, so that the driver can notice it,


    In the same way as the vehicle speed controller, it performs the pertinent maneuvers to condition the speed of the vehicle to that of the received sound emission signal (acoustic or spoken), which warns about the signal received with the idea of previously capturing the driver's attention
    The receiver (2) is integrated in the CAN-BUS (4) of the vehicle, which sends an order to the motor control unit (5), which has a speed regulation-limitation system implemented and makes it appropriate automatically to her.
    On the other hand, the emitter (1) of infrared or radiofrequency signal placed in the traffic signals emits information, and the receiver (2) in the vehicle receives it and transforms it into information inside the vehicle, on the screen Display
    (3) located, in a place of easy vision for the driver, and at the same time transforms it into spoken (auditory) and image (visual) information.
    If the vehicle does not include a screen in which to visualize the information, alternatively, a screen external to the vehicle will be included in a place suitable for easy viewing and hearing of the dashboard, additionally incorporating, in both cases, a small speaker.
    It is expected that this same signal, alternatively, will be received by a hearing aid (6), which emits a spoken message. Thus, in some cases, as has been said, the location of the emitter signal in the sirens of emergency vehicles (firefighters, ambulances, police) is expected, being received by the indicated hearing aid (6), which will do so at Hearing impaired people, notice the presence of these vehicles without the need to notice only, visually.
    Alternatively, the display of the signal on a mobile phone (7), which receives an MSM data message, is also provided. The signal, in this case, emits at the same time an MSM, data message, which the user's mobile phone (7) receives, to translate it into a graphic message on the mobile phone screen (7) and a message spoken with the content of the traffic signal limitation.
    The traffic signal emits an infrared or radiofrequency signal of a usable frequency, such as 433 MHz, which is the frequency at which most remote controls emit and which have a range of tens of meters with a power of


    very small emission (this would favor the autonomy of the feeding by means of solar panels and batteries for isolated signals of the electrical network). Furthermore, in this frequency, data such as those transmitted, for example, in car remote controls, keyless opening cards or tire pressure sensors can be transmitted. Is
    5 something that is already used in cars and whose implementation does not imply rejection bypart of the manufacturers. In addition, it has no impact on electronic systemsof vehicles, since there are permanently very different emissions in that band andThey are not affected or disturbed.
    10 Given the possible problem of how to distinguish the infrared or radiofrequency signals from each side of the roads, it is expected that the system takes into account the preceding signal, that is, that the signals have an identification code, so that the receiver ( 2) only pay attention to signals whose code was earlier than the one you received previously. Otherwise, I would ignore the signal. Another possible way, and more simple and efficient, is
    15 taking into account the direction of movement, that is, that the vehicle is provided with GPS or at least one electronic compass, so that each signal corresponds to a direction of movement and thus infrared or radiofrequency signals can be discriminated on each side of the road.
    20 When the infrared or radiofrequency signal reaches the vehicle, that receiver (2) is integrated into the CAN-BUS network (4).
    The CAN communications protocol provides the following benefits:
    25 -It is a standardized communications protocol, which simplifies and saves the task of communicating subsystems of different manufacturers over a common network or bus.
    - The host processor delegates the communications load to a smart peripheral, therefore the host processor has more time to execute its own tasks.
    - Being a multiplexed network, it considerably reduces the wiring and eliminates the point-to-point connections - except in the vehicle hooks. The motor control unit itself has implemented the regulation system-
    speed limitation


    Diesel electronic regulation (EDC).
    Electronic diesel regulation (EDC) is an electronic engine management system
    5 diesel Bosch was the first company that introduced it in 1986 for passenger cars, since 1989 it is also used in industrial vehicles and today it is a standard equipment. The EDC brings together all the regulation and control functions in an electronic control module. Connected to it is the injection system and a large number of sensors and actuators.
    10 Bosch electronic diesel regulation optimally controls diesel injection for every service situation. It assesses in real time the data of the sensors about the temperature of the coolant, the fuel and the suction air, as well as the current revolutions, the position of the accelerator and the mass of sucked air. With these values, the EDC calculates the best possible injection process.
    15 Due to the different requirements, EDC offers a wide range of functions in commercial vehicles. Among other things it serves to limit the number of engine revolutions to directly limit the maximum speed in industrial vehicles. In many countries there are legal provisions that regulate these speed limits. The
    20 electronic speed limitation can be extended, making it a speed limiter for each gear and thus protect the engine and transmission
    In addition, the EDC allows you to manually connect an engine brake to protect the wheel brake from overheating. If there is a data connection to the module
    25 control of the anti-lock system, the engine brake can be integrated into the brake system, so that it is automatically activated.
    Another option of the EDC allows to realize in industrial vehicles the so-called regulation of the intermediate revolutions like the winch of the cable, hydraulic groups or stairs. The
    30 intermediate speed regulation keeps the engine revolutions constantly, even if there are different loads.
    As modern cars no longer have throttle cable, no mechanism is needed to regulate speed, Tempomat Type of the old Mercedes, or the
    35 speed limiters of old trucks.


    The vehicle incorporates two sources of information for the speed system: one from the driving position (which many vehicles carry) and another from the receiver (2) of the information transmitted by the traffic signals. In either case, the behavior of the vehicle would be the same: the vehicle responds to the accelerator as long as the speed it develops is lower than that set by the limiter (either the one set by the driver or the one arriving from the limiting signal ) To avoid safety problems, these systems have a switch at the end of the throttle travel
    or of the brake so that, if it is necessary to lower the maximum speed set for any reason, the accelerator is simply pressed until the end of the travel, or the brake is pressed and, at that time, the speed limitation is switched off. This switch is similar to kick-down vehicles with automatic transmission. In order to operate in a coordinated manner with the speed limiter regulator, some kind of priority is expected. The normal thing in current vehicles that have both a speed regulator and a limiter of the same, is that they are exclusive functions of one another: the speed limiter by contraposition speed regulator. In this case, the same option is foreseen: you must choose voluntarily and manually if you want the speed limiter to be active. And in the event that the two modes of the speed limiter were activated, an order of priority must be established: the one with the lowest speed, the one marked by the driver, or other options.
    The way in which the mechanical component acts to make possible the variation of speed after receiving the order of the computer, is, as described above, the usual modern cars (diesel since 1998 approximately and gasoline since 2002, approximately ), where throttle cable no longer exists. In diesel vehicles, they have the power system that they have, although now they are all common-rail, the "accelerator" is controlled by the engine ECU, simply by modifying the injection times.
    In gasoline vehicles, in addition to modifying injection times, it is necessary that the throttle is motorized (which is currently normal) or that they have some control system on the amount of air entering the engine (variable elevation of valves, for example).
    All this makes the vehicle adapt to the speed it receives from traffic signals; which would be applicable to modern vehicles, that is to say they have a CAN-BUS network (4) and have electronic engine management (including speed regulation). For a few years now, almost all vehicles have these systems.


    It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom. The elements that compose it or its implementation technique will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.
