Description
Dispositivo incorporado en vehículos a motor equipados de un sistema de limitación de velocidad, que facilita el adelantamiento, así como su procedimiento.Device incorporated in motor vehicles equipped with a speed limitation system, which facilitates the overtaking, as well as its procedure.
La presente invención se refiere a un dispositivo que facilita el adelantamiento entre vehículos, estando destinado a vehículos a motor que disponen de un limitador de velocidad, de manera que permita evitar situaciones de alto riesgo en las carreteras por la baja velocidad relativa a la que se realizan los adelantamientos.The present invention relates to a device that facilitates overtaking between vehicles, being intended for motor vehicles that have a limiter speed, so as to avoid high risk situations on the roads due to the low relative speed at which They make overtaking.
El objeto de la invención es un dispositivo que facilita el adelantamiento, permitiendo un incremento en la velocidad del vehículo por encima del valor límite del limitador durante el adelantamiento, consiguiendo un incremento de la velocidad relativa de adelantamiento y disminuyendo el tiempo necesario para el adelantamiento, y en consecuencia, el riesgo de accidente.The object of the invention is a device that facilitates overtaking, allowing an increase in vehicle speed above the limit value of the limiter during overtaking, achieving an increase in relative speed of overtaking and decreasing time necessary for overtaking, and consequently, the risk of accident.
También es objeto de la invención el procedimiento que facilita el adelantamiento entre vehículos con la ayuda de dicho dispositivo.The object of the invention is also the procedure that facilitates overtaking between vehicles with the help of said device.
Actualmente, es muy común ver como en las carreteras y autovías los adelantamientos entre vehículos pesados producen situaciones de alto riesgo motivadas principalmente por la baja velocidad relativa a la que se producen debido al uso obligatorio del limitador de velocidad.Currently, it is very common to see how in the roads and highways overtaking heavy vehicles produce high-risk situations motivated mainly by the low relative speed at which they occur due to use mandatory speed limiter.
Esto provoca que en los adelantamientos entre vehículos pesados se produzcan tiempos excesivos de adelantamiento, riesgos de choque frontal, así como riesgos derivados de las retenciones creadas en un adelantamiento.This causes the overtaking between heavy vehicles occur excessive overtaking times, frontal crash risks, as well as risks arising from retentions created in an overtaking.
En el estado de la técnica existen muchos documentos acerca de dispositivos limitadores de velocidad como es la patente española ES 506.567 que se refiere a un sistema de control automático de velocidad para un vehículo pesado que consta de medios para limitar la señal de velocidad ordenada a un valor establecido cuando excede de un límite determinado.In the state of the art there are many documents about speed limiting devices such as Spanish patent ES 506,567 which refers to a system of automatic speed control for a heavy vehicle consisting of of means to limit the ordered speed signal to a value established when it exceeds a certain limit.
Por otra parte, tenemos la patente de invención ES 2.109.864 que dispone de un dispositivo limitador de velocidad que obliga al conductor a reducir la velocidad por debajo de una velocidad limite inferior predeterminada.On the other hand, we have the invention patent ES 2,109,864 which has a speed limiting device which forces the driver to reduce speed below a default lower limit speed.
La patente ES 502.729 se refiere a un dispositivo de limitación de velocidad destinado a limitar la velocidad máxima del vehículo, asegurando simultáneamente la plena potencia del motor en el curso de las fases de aceleración.Patent ES 502.729 refers to a speed limitation device intended to limit the maximum vehicle speed, simultaneously ensuring full engine power in the course of the acceleration phases.
En la actualidad, los limitadores existentes no son capaces de detectar situaciones de peligro, limitándose solamente a no permitir que la velocidad del vehículo sobrepase aquella para la que están programados, sin permitir aumentar esta velocidad límite en ninguna situación.Currently, existing limiters do not they are able to detect dangerous situations, limiting themselves only to not allow the vehicle speed to exceed the one for which they are programmed, without allowing to increase this speed limit in any situation.
En el estado de la técnica también tenemos una serie de dispositivos que facilitan las maniobras de adelantamiento de los vehículos. En el caso de la patente española ES 552.135 se tiene un dispositivo para transmitir al conductor de un vehículo que va a ser adelantado la intención del conductor de un vehículo que por el contrario quiere adelantar que comprende unos emisores y receptores de señal.In the state of the art we also have a series of devices that facilitate overtaking maneuvers of the vehicles. In the case of Spanish patent ES 552,135, It has a device to transmit to the driver of a vehicle that the intention of the driver of a vehicle will be advanced which on the contrary wants to advance that includes some emitters and signal receivers
Por otro lado, el modelo de utilidad español ES 281.036 U describe un dispositivo de adelantamiento de vehículos automóviles que comprende un espejo situado en la parte posterior lateral izquierda del vehículo, colocada de tal forma que refleja en el retrovisor exterior de origen, la imagen anterior del carril contrario por el que se circula.On the other hand, the Spanish utility model ES 281.036 U describes a vehicle overtaking device cars comprising a mirror located at the back left side of the vehicle, positioned in such a way that it reflects in the original exterior mirror, the previous image of the lane opposite by which it circulates.
En el caso particular de la CEE, la instalación
y utilización de dispositivos de limitación de velocidad en
vehículos pesados de diferentes categorías viene regulado por la
directiva 92/6/CEE del Consejo, de 10 de febrero de 1992, la cual
dicta los diferentes limitadores que deben instalar los diferentes
vehículos y a las velocidades a las que se limita su
velocidad.In the particular case of the EEC, the installation and use of speed limitation devices in heavy vehicles of different categories is regulated by Council Directive 92/6 / EEC of 10 February 1992, which dictates the different limiters that the different vehicles must install and at the speeds at which their
speed.
El articulo 2 de esta directiva dicta que para vehículos de motor de la categoría M3 (destinados al transporte de personas que tengan, además del asiento del conductor, más de ocho plazas sentadas y que tengan un peso máximo que supere las 5 toneladas) sólo puedan circular por la vía pública si están equipados con dispositivos en los que la velocidad máxima esté limitada a 100 km/h.Article 2 of this directive dictates that for motor vehicles of category M3 (intended for the transport of people who have, in addition to the driver's seat, more than eight seats seated and having a maximum weight that exceeds 5 tons) can only circulate on public roads if they are equipped with devices where the maximum speed is limited to 100 km / h.
Por otro lado, el articulo 3 dicta que para vehículos de motor de la categoría N3 (Vehículos destinados al transporte de mercancías con un peso máximo superior a 12 toneladas) sólo puedan circular por la vía pública si están equipados con un dispositivo regulado de tal manera que su velocidad no pueda superar los 90 km/h; habida cuenta de la tolerancia técnica admisible, en el estado actual de la tecnología, entre el valor de regulación y la velocidad real de circulación, la velocidad máxima en dicho dispositivo estará limitada a 85 km/h.On the other hand, Article 3 dictates that for Motor vehicles of category N3 (Vehicles intended for freight transport with a maximum weight greater than 12 tons) can only circulate on public roads if they are equipped with a regulated device such that its speed cannot exceed 90 km / h; given the permissible technical tolerance, in the current state of technology, between the regulation value and the actual speed of movement, the maximum speed on said device will be limited to 85 km / h
La circunstancia de que esta limitación de velocidad provoque en las carreteras y autopistas una situación de riesgo considerable en los adelantamientos entre vehículos pesados es lógica si se piensa que el vehículo no está dotado de sensores que permitan evaluar situaciones, en este caso de adelantamiento, y con ello tomar decisiones que permitieran para el momento puntual del adelantamiento un pequeño incremento de la velocidad de los vehículos que realizan un adelantamiento, consiguiendo con ello que la velocidad relativa del adelantamiento aumente y con ello se disminuya el riesgo de los peligros que aparecen en estas maniobras.The circumstance that this limitation of speed causes on the roads and highways a situation of considerable risk in overtaking between heavy vehicles It is logical if you think that the vehicle is not equipped with sensors that allow to evaluate situations, in this case of overtaking, and with it make decisions that allow for the specific moment of overtaking a small increase in the speed of vehicles that carry out an overtaking, thereby achieving that the relative speed of overtaking increases and with it reduce the risk of the dangers that appear in these maneuvers
También es importante destacar que los vehículos cada vez están dotados de mejores equipamientos y de motores que permiten una conducción mucho más segura y de mayor velocidad. Sin embargo, la restricción de su velocidad perjudica nefastamente estas ventajas de la técnica cuando realmente son necesarias como es el caso de los adelantamientos, y en los que un incremento de la velocidad fijada por los limitadores significaría un considerable beneficio para la seguridad de todos los vehículos involucrados en dicha maniobra. Además, el hecho de circular a una velocidad constante durante horas y en vehículos con las prestaciones de hoy en día, supone un factor más que contribuye a la fatiga o distracción de un conductor, una de las principales causas de siniestralidad en carretera.It is also important to note that the vehicles each time they are equipped with better equipment and engines that They allow a much safer and faster driving. Without However, the restriction of its speed negatively damages these advantages of the technique when they are really necessary as is the case of overtaking, and in which an increase in speed set by the limiters would mean a considerable Safety benefit of all vehicles involved in said maneuver. In addition, the fact of circulating at a speed constant for hours and in vehicles with today's performance in day, it is another factor that contributes to fatigue or driver distraction, one of the main causes of road accident.
El dispositivo que facilita el adelantamiento que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta de manera que permite en el momento del adelantamiento un pequeño incremento de la velocidad de los vehículos que adelantan, consiguiendo con ello que la velocidad relativa del adelantamiento aumente y se disminuya el riesgo de los peligros que aparecen en estas maniobras.The device that facilitates overtaking which is recommended resolves in a fully satisfactory manner the problematic previously exposed in a way that allows in the time of overtaking a small increase in the speed of the vehicles that advance, thereby achieving that speed Relative overtaking increases and the risk of dangers that appear in these maneuvers.
Este dispositivo que facilita el adelantamiento se incorpora en la electrónica del vehículo con el resto de los circuitos que controlan otros dispositivos electrónicos como, por ejemplo, el ABS, el EBD, el ESP, el 4ETS, etc.This device that facilitates overtaking is incorporated into the vehicle electronics with the rest of the circuits that control other electronic devices such as example, ABS, EBD, ESP, 4ETS, etc.
La invención queda enmarcada dentro del ámbito de la automoción, y en especial en el terreno de los vehículos pesados (camiones y autobuses), pero sin descartar la posibilidad de aplicación a otros vehículos, los cuales disponen de un limitador de velocidad que les impide circular a una velocidad superior a la que le permite la ley.The invention is framed within the scope of the automotive industry, and especially in the field of vehicles heavy (trucks and buses), but without ruling out the possibility applicable to other vehicles, which have a speed limiter that prevents them from traveling at a speed superior to what the law allows.

Each of these sensors will be located in the vehicle in a position that allows it Perform its function satisfactorily.
El sistema informático comprende por un lado de un software de gestión de la información recibida y de toma de decisiones, y por otra parte de un software de almacenamiento de datos que identifique características de los vehículos que se adelantan, como la longitud y la velocidad, en orden de evitar, entre otras cosas, posibles adelantamientos sucesivos de dos vehículos que estás compenetrados en esta tarea y con ello ahorrar tiempo en un viaje.The computer system comprises on the one hand a software for managing the information received and taking decisions, and on the other hand of a storage software data that identifies characteristics of the vehicles that are advance, such as length and speed, in order to avoid, among other things, possible successive overtaking of two vehicles that are involved in this task and thereby save Time on a trip.
