A method of positioning a vehicle chassis of a stationary vehicle in
approximate alignment with a predetermined datum is provided. The vehicle
has an axle and a fluid suspension system. The fluid suspension system
include a control device, a pressurized fluid source and an exhaust
passage. The pressurized fluid source and the exhaust passage are in
fluid communication with the plurality of fluid suspension members
through the control device. The vehicle also includes an electronic
control unit operatively associated with the control device. The method
including step of providing alignment sensor supported on the chassis for
outputting a signal indicative of the orientation of the chassis to the
electronic control unit and acquiring a signal output by the alignment
sensor. Another step includes comparing the signal from the alignment
sensor to alignment data stored in the electronic control unit. A further
step includes selectively operating the control device to permit fluid
communication between one or more of the fluid suspension members and one
of the pressurized fluid source and the fluid exhaust until the signal
from the alignment sensor approximately corresponds to the alignment
data. A system for performing the method is discussed.
