Abstract

Instalación de frenos de un automóvil, en la que dispositivos de frenado en sus ruedas son impulsables con presión mediante un cilindro principal de freno, con un servo-freno (21) controlable electrónicamente, con - una cámara de depresión (23) y una cámara de presión (24), las cuales están separadas, una de otra, por una pared desplazable (22), - una disposición de válvula de control (30), que es accionable mediante un dispositivo electromagnético de accionamiento (26) y mediante la cual es regulable una diferencia de presión entre la cámara de presión y la cámara de depresión, variando su posición la pared desplazable (22) dependiendo de las condiciones de presión en la cámara de depresión (23) y la cámara de presión (24) y accionando un cilindro principal de freno, en la cual - el dispositivo electromagnético de accionamiento (26) en funcionamiento es alimentado, por una unidad electrónica de control, conseñales de corriente, que genera la unidad electrónica de control en función de estados dinámicos de marcha o influencias externas, que registran sensores conectados con la unidad eléctrica de control, y - al existir estados dinámicos de marcha o influencias externas o combinaciones de ambos, que hagan necesario el accionamiento del cilindro principal de freno dentro de un intervalo predeterminado de tiempo con una probabilidad predeterminada, la unidad electrónica de control genera señales de corriente para el dispositivo electromagnético de accionamiento, de manera que sea accionada en cierta medida la disposición de válvula de control para que sean superados juegos, recorridos en vacío o recorridos muertos dependientes de tolerancias existentes al menos en el servo-freno caracterizándose la instalación porque - no es realizado ningún accionamiento de los dispositivos de frenado, - la unidad electrónica de control presenta, -un computador para el enlace de las señales registradas por los sensores según reglas pre- determinadas y - una memoria para el almacenamiento de las reglas pre-determinadas, así como de valores experimentales obtenidos durante el funcionamiento de la instalación de frenos del vehículo, y - que son combinaciones de valores experimentales, almacenados en la memoria, de señales registradas de sensor, así como de valores de probabilidad, con los cuales, al existir la correspondiente combinación de señales registradas de sensor dentro de un intervalo de tiempo en el pasado, sería realizado un frenado.
