Abstract
The height adjustment of electronically controlled air suspension is a complicated nonlinear process [1]. To research this problem, the height adjustment principle of ECAS is introduced first, and the functions of important components of the system are also listed. Then we put forward height control strategy and the pulse width of the solenoid valve control method, which are applied to the control method of ECU. After that, we use the software Labview to communicate with the ECU through CAN bus. By analyzing the data collected, we can see that the results show that current height and target height are consistent generally and the control strategy is feasible.
