Abstract

UNA TRACCION DE UN VEHICULO QUE INCLUYE UN SISTEMA DE CONTROL SOMETIDO A LA DEMANDA DEL OPERADOR, Y UNA TRANSMISION DE COEFICIENTE CONTINUAMENTE VARIABLE (CVT), INCLUYE UN MODIFICADOR DEL TIPO DE PAR CONTROLADO, EN EL CUAL EL SISTEMA DE CONTROL INCLUYE UN DIAGRAMA DE FUNCIONAMIENTO DE RELACIONES OPTIMAS ENTRE EL PAR MOTOR Y LA VELOCIDAD SOBRE UN MARGEN DE VALORES DE ESTAS DOS CANTIDADES, Y EN EL CUAL EL SISTEMA DE CONTROL REGULA LA ENTRADA DE ENERGIA A UN MOTOR Y TAMBIEN EL PAR DE REACCION EN EL MODIFICADOR PARA BUSCAR UN ESTADO EN EL QUE SE MANTIENE LA ACCION OPTIMA REPRESENTADA ENTRE EL PAR MOTOR Y LA VELOCIDAD. EL MODIFICADOR PUEDE SER DEL TIPO DE TRACCION GIRATORIA DE CARRERA TOROIDAL, SIENDO REGULADO EL PAR DE REACCION DENTRO DE EL CONTROLANDO LA FUERZA DE ACCIONAMIENTO APLICADA A LOS RODILLOS DEL MODIFICADOR. EL SISTEMA DE CONTROL PUEDE ACTUAR PARA CALCULAR EL PAR DE REACCION DEL MODIFICADOR CON RELACION A DOS CALCULOS ALTERNATIVOS BASADOS EN LOS PARES DE ENTRADA Y SALIDA DE TRANSMISION RESPECTIVAMENTE, Y PUEDE ELEGIR EL CALCULO, PARA EL ACCIONAMIENTO EN CUALQUIER MOMENTO DADO, CONSIGUIENDO EL MENOR VALOR DE ESE PAR DE REACCION DEL MODIFICADOR.
