Abstract:Based on the characteristics of semi-active air suspension, a height and damping joint control mode was proposed to improve the comprehensive performance of vehicles. The proposed mode could approach the practical driving instance. To solve the coupling problem between body height control and damping self-adjustment, a new control strategy was designed to ensure the priority of body height swi-tching. The switching system theory was used to describe the control modes and mode switching process of semi-active suspension, and the logical judgment method was applied to set the mode switching rules. The main switching parameters between different modes were determined by the fuel economy and traffi-cability of vehicles. The modeling and simulation of the switching control system were completed by Si-mulink/Stateflow. The simulation results show that the proposed multi-mode switching control system of semi-active air suspension can effectively identify the running states of vehicles, and can meet the multi-mode switching control requirements.
