This paper presents a novel design for Demand
Dependent Active Suspension (DDAS) focusing on vehicle
rollover control. Active suspensions take credit for improving
ride comfort and handling performance, but to use active
suspension in vehicle rollover control has not been widely
investigated. The proposed active suspension design consists of
four double direction hydraulic actuators, hydraulically
interconnected, and it can actively tilt the vehicle against its roll
motion by supplying a required restoring moment, which is over
the competence of passive or semi-active suspension. Based on a
real vehicle fitted with DDAS, the experimental investigation
validates the effectiveness of DDAS in vehicle rollover control.
