    DESCRIPTION
    Device for the detection and signaling of decelerations in vehicles

     5 SECTOR OF THE TECHNIQUE
    The present invention fits into the technical sector of the manufacture of lighting systems and indication for vehicles.

    BACKGROUND OF THE INVENTION 10
    Currently vehicles make use of lighting and indication systems to warn of a set of possible situations that are listed below:
     Lighting with different intensities and light beams
     Vehicle position
     Position of the vehicle in situations of low visibility 15
     Address changes
     Sense of walking
     Braked
     Emergency
    With the present invention, it is tried to improve the systems of warning of emergencies and braking, by what will only deepen in said categories.

    The braking indication systems are composed of several visual indicators that warn the environment that the vehicle is using its speed reduction system. These indicators can be composed of between 1 to 3 components, namely:
     2-wheel vehicles use a single rear component.
     4-wheel vehicles use 2 components located on both sides of their rear.
     Optionally, depending on the age of the vehicle, vehicles with 4 30 wheels can install a third component known as "third brake light" located in the rear center. This third component arose from the need to provide the other drivers with the differentiation between the brake lights and the position lights of a vehicle, since these are the same color and are located in the same area. 35

    These warning indicators are activated by the vehicle's braking system, which in turn is activated by the driver.
    This type of visual warning does not offer to the environment any type of information about the dynamic state or behavior of the vehicle, only that the driver is making use of the brake system. These warnings work in the same way when the vehicle is stopped 5 when it actually reduces its speed.
    In addition, we must take into account the wide variety of vehicles, the different qualities of the braking systems and the state of maintenance of the same. Current systems do not help to differentiate between the braking of a vehicle equipped with a high-performance braking system with those of average utility or even with those that are not in good condition.

    With regard to emergency warning systems, they are composed of a system of indicators shared with the lane change indication systems. In emergency situations, when braking at high intensity, it is necessary to press 15 manually a specific switch that will activate the emergency lighting system. The emergency signaling issued consists of a rhythmic flashing of the lights.
    Some vehicles include a system that combines braking and emergency systems, automatically activating the emergency indication system in case of detecting high-intensity braking. However, this system is not present in all the vehicles, being necessary the manual activation in the rest. This manual activation entails risks since the driver must let go of the steering wheel and look away to activate the emergency warning.
    Along with this risk of manual activation, we must bear in mind that the time required for a driver to stop acting on the accelerator and actuate the brake in situations of sudden braking is approximately 0.25 seconds. For this reason it is necessary to make an improvement of the current systems.

    There are a large number of documents and previous patents that reflect different solutions to improve warning systems in vehicles. Below are some of them to be considered as the closest prior art.

    The patent ES-2112166_A1 describes a speed reduction warning system independent of the existing braking indication system by means of the use of elements 35
    inertial
    The patent ES-2107361_A1 describes an acceleration or deceleration indicator device in vehicles characterized in that it is capable of disclosing the degrees or levels of acceleration or deceleration that a vehicle experiences at any time.
    The patent ES-2023293_A6 describes a signaling circuit that combines the braking and emergency indication systems 5 according to the speed used when operating a switch.
    Patent WO0100444A1 describes an auxiliary system for controlling the brake and emergency lights of vehicles using deceleration sensors. Combining both systems to warn of emergency situations. 10
    Patents ES-2037002_T3, ES2066725 and ES-2112295_T3 describe systems for activating the brake lights of vehicles in advance, using sensors installed on the brake pedal and inertial elements to detect emergency braking as sources of information.
    The patent ES-2539876_A1 describes a system for the prevention of accidents by rear collision. It consists of a specific control unit, a GPS sensor, connections with the accelerator sensors, braking calculators and the existing brake light system.
    The patent ES-2247761_T3 describes a system progressive brake lights for vehicles that provides an indication to the driver of the vehicle circulating behind about the intensity with which the vehicle equipped with the system is decelerating. This system is composed of an accelerometer and a set of lamps (specific) aligned to indicate the intensity of deceleration according to a pattern of lights.

    As can be seen, there are several precedents in the current state of the art that help to improve the current systems, but all of them in summary are based on:
     Add extra systems in the vehicle
     Installation of more sensors
     Installation of new visual indicator elements 30

    The present invention proposes an alternative solution that entails the following advantages with respect to the state of the art:
     It is not necessary to modify any existing system.
     Does not require installation of any external system or extra sensor. 35
     Does not require the installation of extra visual indicators.
     Uses the same power systems present in the vehicle.
     It is viable for all types of vehicles.
     The installation process is basic, the same as in a maintenance operation of changing bulbs. 5
     It is independent of the speed reduction capabilities of the braking system.
    EXPLANATION OF THE INVENTION
    Intelligent lighting device that monitors by accelerometers the 10 decelerations suffered in automobiles, with the aim of improving braking and emergency indication systems.
    The device will be composed of an electronic system and luminous elements.
    Both the electronic system and the lighting elements will be self contained in the bulb format used in the current automotive industry. fifteen
    The device will have the same dimensions as the bulbs used today and will use the same power and anchoring system.
    The device replaces the bulbs used in the braking lighting system, maintaining its basic functions and adding the improvements presented by the invention, the device of the present invention being considered as improved brake lights.
    Improves braking and emergency warning systems, contemplating all deceleration situations and operating in an objective manner.
    It will help to determine in a reliable way when a vehicle is really slowing down and when it should be considered emergency or high intensity. 25
    By using accelerometers to monitor the movements of the vehicle you can accurately determine the deceleration intensity, regardless of the characteristics of the car or the type of brake system and / or the state in which it is located.
    The warning of a high-intensity braking will consist of a high-speed intermittent ignition of the luminous elements that the device incorporates. 30
    The determination of when it is a normal braking and an emergency braking will be defined by the readings obtained by the accelerometer, being able to change from a normal braking situation to an emergency one and vice versa. The device will report a deceleration or an emergency situation, without the need for intervention of any external system or human activation. 35
    The behavior of the device in the different situations will be as follows:
     Driver  Vehicle Improved brake lights
     Accelerate  Increase or maintain speed Off
     Does not accelerate and does not brake  Increase or maintain speed Off
     Does not accelerate and does not brake  Reduce speed On
     Brake  Reduce speed On
     Brakes with high intensity  Reduce speed Lit with flashing

    Therefore the device maintains the basic functionality of the current bulbs and adds two improvements, informing when the vehicle decelerates without the brakes intervening and the warning of a high intensity braking. 5

     fifteen
    First, the electronic system will be composed of a circuit that regulates the power supply, a 3-axis accelerometer and a processor.
    The device will use the existing bulbs supply system in the vehicles, so it must have a range of tolerances for the different existing voltages, so that it can work in all of them. twenty
    In addition, it will have accumulator elements of energy to have at all times enough energy to monitor the movements of the vehicle, similar to an uninterrupted power supply system. These accumulators are charged when the braking system is used, taking enough energy so that the device can continue working between braking. 25

    To measure the movement, a 3-axis accelerometer will be used. It is necessary that it is of 3 axes to be able to contemplate any position in which the device is installed.

    To operate the system, a processor will be used, responsible for reading the information provided by the accelerometer and controlling the on / off of the indicator lights as required.

    Second, the light indicators will be composed of high intensity LED diodes that occupy the entire upper part of the device. The placement of said diodes 35
    It will depend on the size and shape of the outer shell.

    Third, the outer shell, will constitute design, structure and platform to assemble all the elements and install the device properly in the vehicles.
    This outer casing will also include the necessary connectors to receive the power supply 5 of the vehicle. Its dimensions and design will be adjusted to the formats already existing in the industry, so that it can be compatible with the current lighting systems.
    The upper part of the housing may be formed by a translucent dome that allows homogeneous distribution of the LED light, avoiding bright spots or flashes. The presence of this dome and its size will be subject to the bulb format adopted by the housing, not being a requirement.
