Abstract
A variable spring rate absorber is adjusted to provide the vibration attenuation characteristics needed to match current operating conditions. Control of a variable spring rate absorber determines the desired absorber spring rate for existing conditions based on a number of inputs and predetermined characterization tables. Once the spring rate is calculated, a predetermined map may be used to determine the absorber setting needed to achieve the desired spring rate. A sensor may be used to measure the actual state of the absorber to determine the extent to which the setting must be adjusted to achieve the desired spring rate.
