Abstract

Comprende varios transductores (1, 2, 3, 4) de parámetros del vehículo asociados a respectivos circuitos esclavos (10, 20, 30, 40) comunicados por un único bus serie (60) compartido en el tiempo con un circuito maestro (50) que, al ser activado desde una unidad de procesamiento digital (DP), efectúa una comunicación con cada uno de los circuitos esclavos, circulando a través de dicho bus serie (60) una trama de bits conforme a un protocolo de transmisión, sin corrección de error, formado por una serie de paquetes de bits cada uno con información de un correspondiente circuito esclavo y separados por un breve intervalo temporal, cuya información es almacenada en dicho circuito maestro (50) de donde es adquirida por la (DP) a través de un bus paralelo (70).
