Abstract: A suspension system for a vehicle includes a plurality of air spring assemblies, each having an air spring, and a suspension position sensor; and a controller. The controller is programmed to determine corner forces associated with each air spring of the plurality of air spring assemblies based on a pressure provided by a pressure sensor and an effective area of each air spring of the plurality of air spring assemblies based on a total length provided by the suspension position sensor, according to a target total length of each air spring.
