Abstract
A method is disclosed for controlling a suspension corner connected to a road wheel in a vehicle's adjustable suspension system. The method includes monitoring operation of the vehicle, detecting an occurrence of a predetermined vehicle event, and detecting a road speed of the vehicle. The method also includes monitoring a ride height of the vehicle at the suspension corner. The vehicle ride height at the suspension corner is selected via a bladder arranged at the suspension corner. The bladder is characterized by a variable height and configured to pump a fluid in response to forces generated at the road wheel and hold a volume of the fluid. The method additionally includes selecting the ride height at the suspension corner in response to the detected occurrence of the predetermined vehicle event and the detected vehicle road speed by regulating the volume of the fluid being held by the bladder.
