Abstract

Se provee un sistema para control de suspensión de aire automático en combinación con un vehículo que tiene un eje posterior no impulsado, un eje posterior impulsado y una suspensión de aire asociada con los ejes posteriores para aplicar una carga a cada uno de los ejes posteriores. El sistema de control de suspensión de aire se programa para mantener la carga aplicada al eje posterior no impulsado a un nivel que es menor que la carga aplicada al eje posterior impulsado hasta que la carga aplicada al eje posterior impulsado sea igual a una cantidad de umbral. La cantidad de umbral puede ser igual a la carga máxima que puede ser aplicada legalmente al eje posterior impulsado o algún nivel inferior. Puede no haber carga aplicada al eje posterior no impulsado antes de la carga sobre el eje posterior impulsado alcanzando la cantidad de umbral o puede ser una cantidad que no es de cero.
