description UN METODO Y SISTEMA PARA CONTROLAR LA REDUCCION DE VELOCIDADES DE UN SISTEMA AUTOMATICO DE TRANSMISION MECANICA QUE DETECTA INTENTOS FALLIDOS DE APLICAR UNA RELACION DE REDUCCION DE VELOCIDAD PREDETERMINADA (GR SUB,T}) DEBIDO A QUE LA VELOCIDAD DEL MOTOR SIGUE SIENDO MENOR QUE LA VELOCIDAD SINCRONA DEL MOTOR (ES = OS*GR SUB,T}) PARA APLICAR LA CITADA RELACION DE REDUCCION Y, EN RESPUESTA A LA DETECCION DE TALES CONDICIONES, INICIA AUTOMATICAMENTE UN MODO DEGRADADO DE FUNCIONAMIENTO DONDE SE IDENTIFICA Y SE PROVOCA LA APLICACION DE UNA RELACION DE REDUCCION EN MODO DEGRADADO REALIZABLE (GR SUB,D-MT} < ES SUB,MAX}, OS), SINCRONIZABLE A LA MAXIMA VELOCIDAD CONSEGUIDA DEL MOTOR (ES SUB,MAX}). A method and system for controlling downshifting of an automated mechanical transmission system which senses unsuccessful attempts to engage a predetermined downshift target gear, ratio (GRT) due to engine speed remaining less than the synchronous engine speed (ES = OS*GRT) for engaging said target gear ratio and, in response to sensing such conditions, automatically initiates a degraded mode of operation wherein an achievable degraded mode target gear ratio (GRDMT < ESMAX , OS), synchronizable at achieved maximum engine speed (ESMAX), is identified and caused to be engaged.
