Based on semi-active interconnected air suspension system full vehicle dynamic model, Hierarchical control strategy is used to design LIAS control system to improve vehicle riding comfort.The upper layer is mode judgements layer ,and the lower layer is interconnection condition control and damping condition control layer.Interconnection condition control rules are carried out by taking vehicle speed, steering wheel angle and vehicle roll angle as input parameters.On base of the model,simulation results show that vehicle riding comfort increases by 29.2% and 3.37% through using mixed SH-ADD control than that of SH and ADD control individually,and vehicle roll angle reduces effectively under double-lane condition by using sport mode control rules.
