Abstract

SE PRESENTA UN METODO Y UN SISTEMA PARA REDUCIR LA VELOCIDAD DE ELEVACION DE LA PRESION DEL FRENO BAJO CONDICIONES DE SUPERFICIE DE FRENADO DE BAJO MU UTILIZANDO UNA VELOCIDAD DE REFERENCIA DEL VEHICULO Y UNA RELACION DE SANGRADO FIJA PARA DETERMINAR SI LAS RUEDAS ESTAN O NO SOBREFRENADAS. CUANDO SE PRODUCE EL SOBREFRENADO, LA VELOCIDAD DE ELEVACION DE LA PRESION SE RESTRINGE NO PERMITIENDO QUE UNA VALVULA ABS (10) SE DISPONGA EN EL ESTADO DE APLICACION (APROXIMADAMENTE 100 PSI/SEG), A PESAR DE LOS NIVELES DE ACELERACION DE LA RUEDA. SE UTILIZA UN ESTADO DE DECLIVE EN LUGAR DEL ESTADO DE APLICACION Y LA ELEVACION DE PRESION SE LIMITA HASTA APROXIMADAMENTE 30 PSI/SEG. PARA MEJORAR EL CONTROL DE LA RUEDA. EL CICLO DE OCUPACION DE DECLIVE SE MODIFICA TAMBIEN PARA SUMINISTRAR LOS PASOS DE PRESION MINIMOS QUE SEAN POSIBLES CON EL DISPOSITIVO DE VALVULA ACTUAL.
