Abstract: A method of determining appropriate conditions for leveling a vehicle having a height adjustable air suspension system. The method includes the steps of providing an acceleration-determining device adapted to output a signal associated with an acceleration of the vehicle. Another step includes measuring an acceleration value of the vehicle and comparing the acceleration value to a pre-determined signal. Yet another step includes determining whether appropriate conditions exist for leveling the vehicle based on the comparison. A system for performing the steps of the method is also included.

Abstract: A method of adjusting a leveled height of the sprung mass of a vehicle that is in approximate alignment with a predetermined datum includes approximately aligning the sprung mass with the predetermined datum. The method also includes receiving an input from an operator for changing the leveled height of the sprung mass. The method further includes adjusting the leveled height of the sprung mass while maintaining approximate alignment with the predetermined datum. A system for performing the method is also discussed.
