Abstract

The improvements comprise the incorporation in the signalling system of a speed sensor (1), of any type, which measures continuously the instantaneous speed value and which provides also permanently the appropriate signals to a deceleration discriminator (2) provided with minimal speed and deceleration thresholds adjustable by means of corresponding controls (3 and 4) and, in case of exceeding said thresholds, an output signal (5) is generated in order to close a complementary optical brake signalling circuit, such as for example the winking light circuit of the vehicle, the stop light circuit or any other circuit, an emergency signal being generated when the deceleration is due to a sudden braking. A switch (7) allows to override said auxiliary circuit or to provide a manual or automatic operation for said auxiliary circuit.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a unos perfec¬ cionamientos introducidos en los sistemas actuales de señalización de la maniobra de frenado en vehículos automóviles, perfeccionamientos orientados hacia la consecución de una mejor señalización, concretamente de dos niveles de señalización diferentes correspondien¬ tes uno de ellos a lo que podría denominarse una frenada suave o normal y otro a una frenada intensa, esta última con un mayor riesgo de impacto para el vehículo que circule inmediatamente detrás, por ser la deceleración mucho más brusca.The present invention relates to improvements introduced in the current signaling systems of the braking maneuver in motor vehicles, improvements oriented towards the achievement of better signaling, specifically of two different signaling levels corresponding one of them to what could be called a smooth or normal braking and another to an intense braking, the latter with a greater risk of impact for the vehicle that circulates immediately behind, as the deceleration is much more abrupt.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, los vehículos a motor. incorpo¬ ran una pareja de pilotos posteriores, señalizadores de la maniobra de frenado, alimentados desde la batería del vehículo y a través de un pulsador accionado por el pedal de freno, de manera que cuando se actúa sobre este último se cierra el circuito de alimentación de aquéllos y se produce el consecuente encendido de los mismos.As is known, motor vehicles. they incorporate a pair of rear pilots, braking maneuver indicators, fed from the vehicle's battery and through a push-button operated by the brake pedal, so that when the latter is actuated, the power supply circuit is closed. those and the consequent ignition of the same takes place.
Ello supone una señal de intensidad constante que origina exactamente la misma señalización tanto cuando se actúa levemente sobre el pedal de freno, sin prácticamente incidir en la velocidad del vehículo, como cuando se realiza una frenada brusca con una desace- leración máxima del vehículo.This implies a constant intensity signal that causes exactly the same signaling both when the brake pedal is operated slightly, without practically affecting the vehicle speed, or when abrupt braking is performed with a slowdown. maximum vehicle rating.
De acuerdo con lo anteriormente expuesto y como es obvio, la señalización resulta insuficiente ya que el conductor del vehículo que circula detrás, el que ha de recibir dicha señalización, tan sólo detecta que se está produciendo una maniobra de frenado, pero desconoce si tal maniobra requiere por su parte de un frenado suave o de un frenado lo más brusco posible para evitar el impacto.In accordance with the foregoing and as it is obvious, the signaling is insufficient since the driver of the vehicle that is driving behind, the one that has to receive said signaling, only detects that a braking maneuver is occurring, but does not know if such a maneuver requires, on the other hand, a soft braking or braking as abruptly as possible to avoid impact.
Como también es sabido, los vehículos a motor cuentan con otros sistemas de señalización, como por ejemplo un circuito que, a través de un pulsador, alimen- ta simultáneamente todos los intermitentes del vehículo, siendo frecuente hacer uso de este tipo de señalización cuando se pretende informar a los conductores posteriores de una situación de emergencia.As is also known, motor vehicles have other signaling systems, such as a circuit that, through a push-button, simultaneously feeds all the turn signals of the vehicle, making frequent use of this type of signaling when It intends to inform subsequent drivers of an emergency situation.
Sin embargo, cuando esta emergencia es más grave y requiere de una frenada muy brusca, la propia tensión del momento y la necesidad en muchas ocasiones de controlar la dirección del vehículo, impiden al con¬ ductor del mismo actuar sobre el interruptor de este circuito, bien por olvido o por verdadera imposibilidad material de hacerlo, y en el mejor de los casos cuando la señalización se produce, por su carácter manual, resulta demasiado tarde.However, when this emergency is more serious and requires a very sharp braking, the actual tension of the moment and the need in many occasions to control the direction of the vehicle, prevent the driver from acting on the switch of this circuit, either because of forgetfulness or because of the real material impossibility of doing so, and in the best case when the signaling occurs, due to its manual nature, it is too late.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
Los perfeccionamientos que la invención propone han sido concebidos para resolver esta problemática a plena satisfacción, y se basan en la utilización de un detector de la velocidad, que analiza permanentemente esta última y que suministra la correspondiente informa¬ ción a un discriminador de la desaceleración, estable¬ ciéndose para este último un umbral de operatividad, de manera que cuando dicha desaceleración se mantiene por debajo del nivel preestablecido el sistema de señali¬ zación funciona de forma convencional, mientras que cuando la desaceleración sobrepasa dicho límite, en correspondencia con una situación que podría considerarse ya de emergencia, dicho discriminador activa una salida que cierra un circuito auxiliar de señalización, como puede ser el de intermitencias o cualquiera otro.The improvements proposed by the invention have been designed to solve this problem to full satisfaction, and are based on the use of a speed detector, which is constantly analyzed the latter and providing the corresponding information to a decelerator discriminator, establishing an operational threshold for the latter, so that when said deceleration is kept below the preset level the signaling system operates in a way conventional, while when the deceleration exceeds said limit, in correspondence with a situation that could already be considered an emergency, said discriminator activates an output that closes an auxiliary signaling circuit, such as intermittence or any other.
De acuerdo con otro de los perfeccionamientos de la invención, el sistema de señalización es ajustable permitiendo prefijar los valores de velocidad y desace¬ leración mínima, a partir de los cuales se activa la señal de salida.According to another of the improvements of the invention, the signaling system is adjustable allowing to set the minimum speed and deceleration values, from which the output signal is activated.
De acuerdo con otro de los perfeccionamientos de la invención, el sistema procesa también el tiempo que debe estar activada la señal de salida.According to another of the improvements of the invention, the system also processes the time that the output signal must be activated.
Se ha previsto también, y ello constituye otra de las características que se preconizan, que la citada señal de salida esté conectada a la instalación de señalización propiamente dicha a través de un conmu¬ tador que permita anular el sistema o establecer para el mismo dos situaciones de funcionamiento, una manual y otra automática.It is also provided, and this constitutes another of the characteristics that are recommended, that the said output signal is connected to the signaling installation itself through a switch that allows to cancel the system or establish two situations for the same of operation, one manual and another automatic.
DESCRIPCIÓN DE LOS DIBUJOSDESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor compren- sión de las características del invento, se acompaña a la presente memoria descriptiva, como parte integrante de la misma, una hoja única de planos en la que con carácter ilustrativo y no limitativo y en su única figu¬ ra, se ha representado un diagrama de bloques correspon¬ diente a un sistema de señalización de frenado para vehículos a motor, realizado de acuerdo con los perfec¬ cionamientos objeto de la presente invención.To complement the description that is being made and in order to help a better understanding of the features of the invention, it is accompanied to the present descriptive report, as an integral part thereof, a single sheet of plans in which, with an illustrative and non-limiting nature and in its only figure, a block diagram corresponding to a signaling system has been represented of braking for motor vehicles, carried out in accordance with the improvements object of the present invention.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de esta figura puede observarse cómo en un sistema de señalización de acuerdo con los perfeccionamientos que la invención propone participa un pequeño dispositivo electrónico constituido por un detector de velocidad (1 ) , que puede recibir la corres¬ pondiente señal de velocidad desde la propia instalación del vehículo o desde otra adicional, que a su vez puede ser mecánica, electromagnética, fotoeléctrica o de cual¬ quier otro tipo, suministrando dicho detector (1) el valor instantáneo de la velocidad a un discriminador (2) que calcula permanentemente la desaceleración del vehículo, en el caso de que ésta se produzca.In view of this figure it can be seen how in a signaling system according to the improvements proposed by the invention a small electronic device consisting of a speed detector (1) participates, which can receive the corresponding speed signal from the own installation of the vehicle or from an additional one, which in turn can be mechanical, electromagnetic, photoelectric or of any other type, said detector (1) supplying the instantaneous speed value to a discriminator (2) that permanently calculates the vehicle deceleration, in the event that it occurs.
En dicho discriminador (2) se establecen además valores mínimos para la velocidad y para la desacelera¬ ción, regulables a través de correspondientes mandos de gobierno (3) y (4), como por ejemplo respectivos potenciómetros, estableciendo los límites inferiores por encima de los cuales ha de actuar el sistema, concre- tamente activando una salida (5) que cierra el circuito de "stop" del vehículo, el circuito de "intermitentes" o cualquier otro circuito señalizador que se elija al respecto y durante un tiempo establecido también en la circuitería del discriminador (2). Finalmente y como se observa también en el diagrama de bloques de la figura, el circuito (6) está conectado a la salida (5) del sistema con la colaboración de un conmutador (7) preferentemente de tres posicio- nes, una de accionamiento "manual" del circuito (6) de señalización, otra de anulación de dicho circuito (Off), y otra en la que el sistema actúa de forma automᬠtica.Said discriminator (2) also establishes minimum values for speed and deceleration, adjustable through corresponding controls of government (3) and (4), such as respective potentiometers, setting the lower limits above which must operate the system, specifically activating an output (5) that closes the "stop" circuit of the vehicle, the "intermittent" circuit or any other signaling circuit chosen in this regard and for a set time also in the discriminator circuitry (2). Finally and as can also be seen in the block diagram of the figure, the circuit (6) is connected to the output (5) of the system with the collaboration of a switch (7) preferably of three positions, one of actuation " manual "of the signaling circuit (6), another of cancellation of said circuit (Off), and another in which the system acts automatically.
Se consigue de esta manera que el sistema de señalización de frenado pueda actuar, a voluntad del conductor, de forma convencional o con los perfeccio¬ namientos de la invención, es decir, estableciendo dos niveles distintos de señalización en función de que se trate de una frenada suave o de una frenada brusca.It is thus achieved that the braking signaling system can act, at the will of the driver, in a conventional manner or with the improvements of the invention, that is, establishing two different levels of signaling depending on whether it is a smooth braking or sudden braking.
No se considera necesario hacer más extensa esta descripción para que cualquier experto en la mate¬ ria comprenda el alcance de la invención y las ventajas que de la misma se derivan.It is not considered necessary to make this description more extensive so that any subject matter expert understands the scope of the invention and the advantages derived therefrom.
Los materiales, forma, tamaño y disposición de los elementos serán susceptibles de variación siempre y cuando ello no suponga una alteración en la esenciali- dad del invento.The materials, shape, size and arrangement of the elements will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.
Los términos en que se ha redactado esta memo¬ ria deberán ser tomados siempre en sentido amplio y no limitativo. The terms in which this memorandum has been written must always be taken in a broad and non-limiting sense.
