1. A suspension system used to reduce undesirable motion of a vehicle chassis that travels along a roadway having at least one roadway defect, the suspension system comprising:

  • a front tire assembly;

    a rear tire assembly;

    a first adjustable suspension device that couples the front tire assembly to vehicle chassis;

    a second adjustable suspension device that couples the rear tire assembly to vehicle chassis;

    a transmitter, mounted on the vehicle chassis, that sends source signals toward the roadway;

    a receiver mounted on the vehicle chassis, that receives reflections of the source signals from the roadway and, based thereon, generates reflection signals;

    a processing circuit, communicatively coupled to the receiver, that analyses the reflection signals to identify the at least one roadway defect; and

    the processing circuit responds to the identification of the at least one roadway defect by interacting with the first adjustable suspension device before the front tire assembly encounters the at least one roadway defect.
