Abstract

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.
