Abstract: To further improve the performance of interconnected air suspension, an interconnected mode switching strategy has been designed. This strategy first establishes an interconnected air suspension vehicle dynamics model. Then, based on the performance index functions of smoothness and handling stability, a comprehensive evaluation index is designed. By utilizing the changes in the comprehensive index under different connectivity modes, a control strategy for switching interconnection modes is designed. Finally, numerical simulation is conducted, and the simulation results show that the control strategy can significantly improve the performance of interconnected air suspension and enhance ride comfort.
