Abstract:
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 associated with a single front tire; a rear tire assembly associated with a single rear tire; a first adjustable suspension device that couples the front tire assembly to the vehicle chassis; a second adjustable suspension device that couples the rear tire assembly to the vehicle chassis; a plurality of transmitters mounted on the vehicle chassis, one such transmitter for each tire upon which the vehicle travels, that send source signals toward the roadway; a plurality of receivers mounted on the vehicle chassis, one such receiver for each tire upon which the vehicle travels, that receive reflections of the source signals from the roadway and, based thereon, generate reflection signals; a processing circuit, communicatively coupled to the plurality of receivers, 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 first, and individually, with the first adjustable suspension device before the single front tire encounters the at least one roadway defect, and second, and individually, with the second adjustable suspension before the single rear tire encounters the at least one roadway defect.
