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
includes 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 steps of providing an 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 also discussed.
