Patent attributes
Some embodiments provide a fully-actuated suspension system which can provide adjustable displacement of a sprung mass from a neutral suspension position over an unsprung mass. The system includes a variable pressure air spring which can adjust the neutral suspension position and execute low-frequency displacements and a hydraulically-driven piston which can execute high-frequency displacements. The system can communicate information to a driver, via haptic feedback provided via actuator displacements, which can augment the driver's situational awareness. The system can provide augmented vehicle braking via displacing the unsprung mass of the vehicle towards the surface upon which the vehicle rests to increase the normal force and contact area of the unsprung mass on the surface, unload torsion of the wheel induced by applied braking pressure to the wheel, etc. The system can compensate for vehicle oscillations at frequencies below the primary ride frequency, thereby mitigating the risk of occupant motion sickness.
