Abstract
UN CIRCUITO DE ACCIONAMIENTO PARA DESPLEGAR UN PAR DE BOLSAS DE AIRE COMPRENDE DOS RAMAS DE CIRCUITOS CONECTADAS EN PARALELO A TRAVES DE UNA FUENTE DE ALIMENTACION. CADA RAMA DEL CIRCUITO COMPRENDE EN SERIE UN SENSOR DE SEGURIDAD, UN INICIADOR Y UN SENSOR DE CHOQUE, ESTANDO DERIVADO CADA SENSOR POR UN ELEMENTO DE RESISTENCIA CON UNA RESISTENCIA NOMINAL SUSTANCIALMENTE MAYOR DE LA RESISTENCIA NOMINAL DE LOS INICIADORES. DOS PUENTES DE DIODO SEPARADOS, COMPRENDIENDO CADA UNO UN PAR DE DIODOS OPUESTAMENTE POLARIZADOS, PUENTEAN LAS RAMAS DEL CIRCUITO EN CONEXIONES ENTRE LOS SENSORES DE SEGURIDAD Y LOS INICIADORES, Y ENTRE LOS INICIADORES Y LOS SENSORES DE CHOQUE, RESPECTIVAMENTE, PARA PROPORCIONAR TRAYECTOS DE ACCIONAMIENTO MULTIPLE PARA AMBOS INICIADORES. UN MICROPROCESADOR COMPRUEBA LA INTEGRIDAD DEL CIRCUITO DE ACCIONAMIENTO Y DIAGNOSTICA LA PRESENCIA DE FALLO EN EL MISMO MEDIANTE LA LECTURA DE LOS POTENCIALES DE TENSION EN CADA CONEXION, COMPARANDO EL POTENCION DE TENSION EN UNA O MAS CONEXIONES ON LA TENSION DE ALIMENTACION, COMPARANDO LA CAIDA DE TENSION A TRAVES DE LOS PUENTES DE DIODOS CON LAS TENSION DE CONDUCCION POLARIZADA DIRECTA DEL DIODO, Y, SI NO SE HA IDENTIFICADO UN FALLO DETERMINADO, MEDIANTE LA DETERMINACION DEL EFECTO SOBRE EL POTENCIAL DE TENSION EN UNA O MAS CONEXIONES CUANDO SE INCREMENTA LA TENSION DE ALIMENTACION APLICADA A TRAVES DEL CIRCUITO DE ACCIONAMIENTO. EL MICROPROCESADOR DETERMINA PERIODICAMENTE LAS TENSIONES DE CONDUCCION POLARIZADA DIRECTA DE LOS DIODOS DE PUENTE PARA SU UTILIZACION EN LA SECUENCIA DE DIAGNOSTICO ANTERIOR MEDIANTE LA MANIPULACION DE UN CONMUTADOR DE CORRIENTE CONECTADO A UNA CONEXION EN CADA RAMA DEL CIRCUITO Y DETERMINANDO LA CAIDA DE TENSION RESULTANTE A TRAVES DE LOS PUENTES DE DIODOS.
