Abstract

SE SUMINISTRA UNA ESTRATEGIA (FIG. 6) PARA UN METODO / SISTEMA DE CONTROL DE DESCENSO DE POTENCIA, EN BASE A LA DIFERENCIA ENTRE EL RENDIMIENTO OPTIMO Y EL REAL DE UN CONVERTIDOR DE TORSION PARA UN SISTEMA DE TRANSMISION MECANICA AUTOMATICA (12) QUE INCLUYE UN MOTOR (16), UNA TRANSMISION MECANICA (14) Y UN CONVERTIDOR DE TORSION (20) INTERPUESTO ENTRE EL MOTOR Y LA TRANSMISION. EN EL COMIENZO DE UN DESCENSO DE POTENCIA, LA MARCHA A BUSCAR SE DERIVA DE LA DIFERENCIA DE RENDIMIENTO DEL CONVERTIDOR DE TORSION, DE LA ACELERACION DEL VEHICULO, DE LA MARCHA ACTUAL Y DE LA DEMANDA DEL REGULADOR DE ACELERACION. ESTAS CUATRO CONDICIONES DEL VEHICULO SON LOS PARAMETROS DE UNA MATRIZ TETRADIMENSIONAL DE TAL MANERA QUE EL INCREMENTO DE LOS VALORES DE CADA PARAMETRO PROMUEVE UN POTENCIAL MAYOR PARA EL DESCENSO DE LA POTENCIA DE MULTIPLICACION.
