Abstract

UN SISTEMA DE FRENADO ANTI-BLOQUEO DE VEHICULO (ABS) QUE TIENE UNA BOMBA ACCIONADA POR MOTOR (10) PARA PROPORCIONAR EL SUMINISTRO HIDRAULICO AL SISTEMA ABS. EL MOTOR DE LA BOMBA (10) ES CONTROLADO POR UNA SERIE DE DISPOSITIVOS EN FORMA DE UN CONMUTADOR ELECTRONICO (16), COMO UN MOSFET, PARA PERMITIR LA FRECUENTE COMPROBACION DEL CIRCUITO DE MOTOR MEDIANTE IMPULSOS CORTOS QUE PRODUCEN RUIDO NO SIGNIFICATIVO. LA RETROALIMENTACION PARA CONTROLAR LA VELOCIDAD DEL MOTOR SE OBTIENE MIDIENDO LA E.M.F GENERADA POR EL MOTOR (16) DESPUES DE HABER SIDO DESCONECTADO Y DESPUES DE UN RETARDO PARA PERMITIR LA VUELTA DE E.M.F, PRODUCIDA POR LA DESCONEXION DEL MOTOR, PARA DECAER (PREFERIBLEMENTE A CERO) ANTES DE QUE COMIENCE LA OPERACION DE MEDICION. LA TENSION GENERADA ES INTEGRADA DURANTE UN PERIODO DE DESCONEXION DEL MOTOR, SIENDO LA VELOCIDAD DEL MOTOR ESTABLECIDA E ESTE PERIODO MEDIANTE LA RESTA DE LA TENSION INTEGRADA MEDIDA CUANDO ACTUA COMO UN GENERADOR DE LA TENSION DE SUMINISTRO PRINCIPAL (B{SUP,+}). EL SUMINISTRO DE ENCENDIDO CONTROLADO POR CONMUTADOR EN EL SISTEMA ELECTRICO DEL VEHICULO SOLO FUNCIONA UNA COMPUERTA LOGICA (40) PARA CONTROLAR EL SUMINISTRO DE POTENCIA DE BATERIA DIRECTA AL REGULADOR DE TENSION DEL VEHICULO (36), EL CIRCUITO DE MOTOR DE LA BOMBA Y SU CONTROLADOR ELECTRONICO (16) ESTANDO CONECTADOS DIRECTAMENTE AL SUMINISTRO DE BATERIA (B{SUP,+}) PARA ASI ACTUAR COMO UNA BAJADA DE ENERGIA PARA PROTEGER TODOS LOS DISPOSITIVOS DE SILICONA EN EL SISTEMA DE CONTROL ELECTRICO EXCEPTO EL ELEMENTO DE COMPUERTA LOGICA DEL CIRCUITO DE ENCENDIDO.
