Abstract

Un circuito de avería de señales para su incorporación en un circuito de control de un sistema de transmisión automática para vehículos, incluyendo el circuito de control circuitos interruptores accionables para efectuar la introducción de las respectivas relaciones de engranaje de la transmisión en respuesta a una señal de entrada que varía de acuerdo con la velocidad del árbol de salida de la transmisión y que es derivada a partir de un generador que produce una señal fluctuante cuya frecuencia varía con la velocidad del árbol de salida, comprendiendo el circuito de avería de señales un temporizador de intervalos que proporciona una salida en caso de que la señal de generador descienda a cero por un espacio superior a un primer tiempo predeterminado y un circuito monoestable sensible a la salida del temporizador de intervalos y que es pasado por dicha salida a su estado inestable para activar un circuito de seguridad en el circuito de control, permaneciendo dicho circuito monoestable en su estado inestable durante un segundo tiempo predeterminado después de haber desaparecido la salida del temporizador de intervalos.
