1. A suspension system, comprising:
a spring assembly including:
a gas spring; and
an accumulator coupled to the gas spring and including a bladder, the accumulator having a compressed state and an uncompressed state;
at least one of (a) a first sensor arranged to detect a first pressure on a first side of the bladder and (b) a second sensor arranged to detect a second pressure on a second side of the bladder opposite the first side; and
a controller configured to:
determine an amount of gas in the spring assembly based on at least one of the first pressure and the second pressure;
determine a target amount of gas in the spring assembly; and
adjust the amount of gas in the spring assembly towards the target amount of gas based on a pressure difference across the bladder.
