Vehicle height adjustment technology can significantly improve vehicle ride comfort and trafficability. Aimed at the problem of poor control accuracy in traditional vehicle height adjustment technology, the mathematical model of the vehicle height adjustment process was established based on fuzzy-PID controller and the control algorithm. Based on Simulink platform, the simulation model was established, and the simulation analysis and experimental verification of the vehicle height rising process were carried out. In order to optimize the problem that the system cannot be stabilized in time during the lowspeed dynamic vehicle height adjustment process, a target vehicle height correction method was proposed. Real vehicle test of fuzzy-PID control algorithm was carried out in a light wheeled platform. The verification results show that the fuzzy-PID control algorithm model is accurate, the actual control effect is good, and the accuracy and stability of vehicle height adjustment are effectively improved.
