英文摘要：

In order to improve vehicle performance, an 8-DOF complete vehicle mathematics model of coach was built and the theoretic analysis and calculating method for integrated control of vehicle body height and adjustable damping were presented to design the integrated control system of tunable damper and the electro-controlled air suspension of coach. On the basis of the simulation calculating, road test of actual vehicle was conducted, the effect of integrated controlled electro-controlled air suspension system was analyzed. The results of simulation calculating and experiment result were consistent. The good matching performance of the air suspension, which was integrated controlled by vehicle body height and tunable damper, and complete vehicle performance achieved, the comprehensive performance of coach was also improved. The study verified the effectiveness of the integrated control strategy and it laid a foundation for the ECAS.
