Design concepts and details for an active roll control systems

Active roll control is a cost effective approach to conventional suspension enhancement. A general active suspension can allow good low frequency vibration isolation and can eliminate body roll and pitch in (low frequency) manoeuvring. However, it is doubtful if car users can discern modest vibration isolation improvements, since they are not sufficiently in touch with the excitation which gives rise to the response which they feel. On the other hand, drivers are themselves responsible for the steering excitation which provokes a manoeuvre, so they are closely connected with both input and response. They seem to be much more impressed by handling improvements than by ride improvements.<
