Zusammenfassung:	PROBLEM TO BE SOLVED: To provide closed loop pressure control for a dual air spring configuration. SOLUTION: An active air suspension system includes an air spring assembly that has a piston airbag and a primary airbag mounted around the piston airbag to provide the variable force and rate dual air spring configuration. The air suspension system is configured to accurately control pressure within the piston airbags in a closed-loop manner. Continuous control of the piston pressure provides an accurate increase or decrease of spring rate or force depending on the controller inputs. COPYRIGHT: (C)2011,JPO&INPIT
