<p>An active air suspension system comprising:
at least one air spring assembly including a piston airbag and a primary air bag mounted around said piston airbag; a plurality of sensors that measure a plurality of vehicle characteristics, said sensors generating a plurality of sensor signals;
a valve assembly that controls air supply into and out of said air spring assembly; and
a controller receives said sensor signals as inputs, analyzes said inputs to determine an appropriate spring output characteristic for said air spring assembly that corresponds to a desired vehicle behavior, and generates an output signal to modify pressure within said air spring assembly to achieve said spring output characteristic. The controller continuously receives sensor signals as inputs, analyzes the inputs to identify system changes, and continuously and actively adjusts pressure within said air spring assembly in response to identified system changes to maintain said desired spring rate/force in a closed-loop manner.
