Abstract

SE OFRECE UN METODO/SISTEMA DE CONTROL (200) PARA UN SISTEMA DE CONTROL (104) PARA EJECUTAR SEMIAUTOMATICAMENTE CAMBIOS DESCENDENTES Y CAMBIOS ASCENDENTES SELECCIONADOS AUTOMATICAMENTE DE UN SISTEMA DE TRANSMISION MECANICO (10). EL SISTEMA DE CONTROL INCLUYE UNA UNIDAD CENTRAL DE PROCESO (106) PARA RECIBIR SEÑALES DE ENTRADA INDICATIVAS DE VELOCIDADES (IS,OS) DE EJE PRIMARIO (16) Y DE EJE DE SALIDA (90) Y PROCESAR LAS MISMAS DE ACUERDO CON LA REGLA LOGICA PREDETERMINADA PARA EMITIR SEÑALES DE SALIDA DE COMANDO A UN ACTUADOR DE TRANSMISION (112,70,96) PARA EJECUTAR LOS CAMBIOS SELECCIONADOS CAMBIANDO AUTOMATICAMENTE A PUNTO MUERTO EN UNA INVERSION DE PAR MOTOR POR CAUSA MANUAL O NATURAL DE LA TRANSMISION Y PERMANECIENDO EN PUNTO MUERTO HASTA QUE EL OPERADOR DEL VEHICULO HAGA QUE SE DEN CONDICIONES BASICAMENTE SINCRONAS. EL METODO/SISTEMA (200) INCLUYE CALCULAR UN VALOR DE REFERENCIA PRIMERO Y SEGUNDO (REF-UP, REF-DN) COMO FUNCIONES DE VELOCIDAD DE EJE PRIMARIO Y SOLO PRESELECCIONAR CAMBIOS ASCENDENTES SI LA ACELERACION DE EJE DE SALIDA (DOS/DT) EXCEDE LA PRIMERA REFERENCIA (REF-UP) Y SOLO PRESELECCIONAR CAMBIOS DESCENDENTES SI LA ACELERACION DE EJE DE SALIDA (DOS/DT) ES MENOR QUE EL VALOR DE REFERENCIA SEGUNDO (REF-DN). LOS VALORES DE REFERENCIA PRIMERO Y SEGUNDO VARIAN CON EL VALOR DE VELOCIDAD DE EJE PRIMARIO POR ENCIMA DE NIVELES (150.154,152-160) CONSIGUIENTES.
