摘      要：This study examines roll stability control for vehicles with an active roll-resistant electro-hydraulic suspension(RREHS)subsystem under steering ***,we derive a vehicle model with four degrees of freedom and incorporates yaw and roll ***,an optimal linear quadratic regulator controller is obtained in consideration of dynamic vehicle ***,an RREHS subsystem with an electric servo-valve actuator is proposed,and the corresponding dynamic equations are ***,field experiments are conducted to validate the performance of the vehicle model under sine-wave and double-lane-change steering ***,the effectiveness of the active RREHS is determined by examining vehicle responses under sine-wave and double-lane-change *** enhancement in vehicle roll stability through the RREHS subsystem is also verified.
