Semi-Active Heave and Roll Control for Large Off-Road Vehicles

Semi-active suspension control deals principally with high bandwidth modulation of passively generated damper forces. When a properly designed semi-active damper is used in an otherwise conventional suspension there is much evidence that a superior overall system results.

Large off-road vehicles, such as military transport vehicles, traveling at high speeds over rough terrain, possess suspension control requirements which are different from a road going vehicle. This paper develops these control requirements.
