The four-corner interconnected air suspension can effectively improve vehicles ride comfort, but the opening of the interconnection will intensify the roll or pitch of the car body, reducing the vehicle handling stability when the vehicles are in the turning, acceleration and deceleration conditions. To solve the above problems, an interconnected state control method is proposed for four-corner interconnected air suspension, the interconnection state of the pipeline is determined by the relationship between the torque produced by the air spring and the roll angles or pitch angles of the car body. The parameters of air spring pressure, car body roll angle and pitch angle are used in the control method to obtain the optimal interconnection state of four interconnected pipelines through control algorithm calculation. Finally, the opening and closing of four interconnected pipeline solenoid valves are controlled. In order to verify the effectiveness of the control method, the MATLAB/Simulink model of four-corner interconnected air suspension is established and simulated.
