Abstract
Systems and methods for controlling a gas spring in a suspension system. The suspension system includes a gas spring and an accumulator coupled to the gas spring and having a bladder. The accumulator may be in a compressed state and an uncompressed state based on a pressure difference across the bladder. A target amount of gas in the gas spring is determined. The amount of gas in the gas spring is adjusted towards the target amount of gas in accordance with a pressure difference across the bladder based on the difference between the first pressure and the second pressure.
