At present,the steering and braking of most autonomous vehicles cannot achieve human-like operation,continuous steering may cause the substantially roll and pitch of the vehicle body especially in complex road conditions,causing the occupants to produce nervousness,dizziness,and other uncomfortable feelings.Therefore,a constant current method was proposed based on the hydraulic electrical energy-regenerative suspension to achieve the coupling control of the damping force and the vehicle attitude to improve the stability of the vehicle body.The 14DOF vehicle model was built according to vehicle dynamics,the snaking condition was selected for simulation analysis,and the real vehicle test was completed.The results show that the body roll angle of the hydraulic electrical energy-regenerative suspension system which adopts the constant current control is reduced by 32%,and the pitch angle is reduced by 1.67% compared with the traditional suspension,which significantly improves the vehicle body stability and verifies the effectiveness of the proposed control method.
