Document Type and Number:
WIPO Patent Application WO/2012/061009
Kind Code:
A3
Abstract:
A vehicle suspension system includes a pump, a gas spring, and an accumulator. The suspension system also includes a controller for adjusting the suspension system. The controller has a processing circuit configured to receive a measure of gas in the spring. The processing circuit is further configured to calculate a difference between a target value and a current value based on the received measure of gas. The processing circuit is also configured to provide an output for adjusting the gas in the spring in response to the calculated difference.
