Abstract：To cooperate damping and body height adjustment of the air suspension effectively, based on the model predictive control theory, a model predictive controller was designed to solve the optimal suspension force under the current vehicle state with vehicle comprehensive evaluation index as cost function, and the suspension forces could be generated by adjustable damper and body height adjustment as constraints. The optimal suspension force was generated by changing damping coefficient of the adjustable damper and charging and discharging operation of the body height adjustment, and the cooperation between damper and body height was obtained. The results show that the proposed cooperative control strategy is feasible and can greatly reduce the sprung mass acceleration of suspension and the root mean square value of tire dynamic load. Under the bump condition, the cooperative control strategy can effectively reduce the vibration peak values of sprung and unsprung mass by 25% and 19%, respectively. Under the turning condition, the strategy can reduce the peak value of vehicle roll angle by 17%.
