Abstract

Se proporciona un sistema de dirección de potencia que tiene dos o "doble" proporciones de dirección. El sistema de dirección de potencia incluye una transmisión que tiene una primer y segunda proporción de engranaje, una caja de dirección acoplada a la transmisión, y una asistencia de potencia acoplada a la caja de dirección para proporciona una asistencia de potencia al sistema de dirección. En una modalidad, el sistema de dirección de potencia está configurado para funcionar con una primera proporción de dirección, tal como una proporción "rápida", durante condiciones de funcionamiento normales del sistema de dirección (por ejemplo, cuando la asistencia de potencia es funcional) y está configurado para funcionar con una segunda proporción de dirección, tal como una proporción "lenta", durante condiciones de funcionamiento anormales del sistema de dirección (por ejemplo, la asistencia de potencia no es funcional, parcialmente funcional, etc.) La segunda proporción de dirección del sistema de dirección puede proporcionar un modo a prueba de fallas para el operador del vehículo de manera que el vehículo puede ser dirigido con seguridad a una ubicación adecuada (por ejemplo, al lado del camino, etc.) durante condiciones de operaciones anormales del sistema de dirección.
