A damping multi-mode adaptive switching control mode was proposed. According to the actual vehicle driving condition and the performance characteristics of electronically controlled air suspension (ECAS), four damping control modes, such as high body height mode, middle body height mode, low body height mode and steering mode, were designed. The switching strategy between different modes was made by logical judgment. By using Simulink/Stateflow, the multi-mode adaptive switching control system was established, which could choose the optimum damping control mode according to the actual driving condition. Based on the control objectives of different control modes, the corresponding damping local controllers were designed to guarantee the local control quality of the system. The vehicle tests of the control system were carried out finally, and the effectiveness and availability of the control method proposed was verified by the experimental results.
