Abstract

SISTEMA ANTI-BLOQUEO PARA CONTROLAR EL NIVEL DE DESLIZAMIENTO EN UNA O MAS RUEDAS DE UN VEHICULO COMPARANDO LA VELOCIDAD REAL DE LA RUEDA CON UNA VELOCIDAD DE REFERENCIA DEL VEHICULO OBTENIDA PROCESANDO UNAS SEÑALES DE VELOCIDAD DE LA RUEDA A TRAVES DE UN SISTEMA DE FILTRADO, EL CUAL CONSTA DE UN ELEMENTO DE SELECCION (10) QUE PRODUCE UNA SEÑAL DE ENTRADA DE UNA O UNA COMBINACION DE LAS VELOCIDADES DE LAS RUEDAS, UN DISPOSITIVO DE DETERMINACION DE ERROR (12) QUE SUBSTRAE LA ESTIMACION DE VELOCIDAD REQUERIDA DEL VEHICULO DE DICHA SEÑAL DE ENTRADA PARA PRODUCIR UN ERROR DE VELOCIDAD (E1), UN DISPOSITIVO NO LINEAL (14) QUE ES EFECTIVO PARA LIMITAR EL COEFICIENTE DE GIRO HORIZONTAL DEL SISTEMA DE FILTRADO TANTO EN DIRECCION POSITIVA COMO NEGATIVA DE ACUERDO CON LAS CARACTERISTICAS DEL VEHICULO, UN FILTRO SECUNDARIO (16) QUE REDUCE LAS OSCILACIONES MOMENTANEAS PRESENTES EN LA SEÑAL DE ERROR, Y UN DISPOSITIVO DE INTEGRACION (20) QUE ACUMULA DICHA SEÑAL DE ERROR Y CUYA SALIDA ES RETROALIMENTADA ADICHO DISPOSITIVO DE DETERMINACION DE ERROR (12) COMO LA ESTIMACION DE LA VELOCIDAD REQUERIDA DEL VEHICULO (VREF)
