Zusammenfassung: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 a 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.
