Title:
RIDE HEIGHT LEVELING CONTROL FOR DUAL AIR SPRING CONFIGURATION
Document Type and Number:
Japanese Patent JP2010241425
Kind Code:
A
Abstract:
To provide ride height leveling control for a dual air spring configuration.
An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other.
