Abstract
SE MUESTRA UN SISTEMA/METODO (200) PARA UN SISTEMA DE CONTROL (104) PARA LA EJECUCION SEMI-AUTOMATICA EL CAMBIO DE MARCHAS AUTOMATICAMENTE SELECCIONADAS DE UN SISTEMA DE TRANSMISION MECANICA (10). EL SISTEMA DE CONTROL INCLUYE UNA UNIDAD DE PROCESAMIENTO CENTRAL (106) PARA RECIBIR LAS SEÑALES DE ENTRADA INDICADORAS DE LAS VELOCIDADES DEL EJE DE ENTRADA DE TRANSMISION (16) Y DEL EJE DE SALIDA (IS, OS) Y PROCESANDO LAS MISMAS DE ACUERDO CON UNA REGLA DE LOGICA PREDETERMINADA PARA EJECUTAR SEÑALES DE COMANDO DE SALIDA A UN CONTROLADOR DE TRANSMISION (112, 70, 96) PARA QUE IMPLEMENTE LOS CAMBIOS SELECCIONADOS MEDIANTE EL CAMBIO AUTOMATICO A PUNTO MUERTO AL PRODUCIRSE NATURAL O MANUALMENTE LA INVERSION DEL TORQUE DE LA TRANSMISION Y QUEDANDOSE EN PUNTO MUERTO HASTA QUE EL OPERADOR DEL VEHICULO PROVOQUE CONDICIONES DE SINCRONIA SUBSTANCIALES PARA QUE SE PRODUZCA. EL SISTEMA/METODO (200) INCLUYE CALCULAR UNOS VALORES DE REFERENCIA PRIMERO Y SEGUNDO (REF-UP, REF-DN) COMO FUNCIONES DE LA VELOCIDAD DE ENTRADA DEL EJE Y SOLO PRESIONANDO CAMBIOS ASCENDENTES DE LA ACELERACION DEL EJE DE SALIDA (DOS/DT) SI EXCEDE LA PRIMERA REFERENCIA (REF-UP) Y SOLO PRESELECCIONANDO CAMBIOS DESCENDENTES SI LA ACELERACION DE SALIDA DEL EJE (DOS/DT) ES MENOR QUE EL SEGUNDO VALOR DE REFERENCIA (REF-DN).
