Commercial vehicles such as public transportation busses can benefit from the height control of the chassisthat an air suspension provides. Main benefits of height control are retaining a pitch angle parallel to theroad for passenger comfort regardless of the load and road disturbance, and easy accessibility to vehicle forespecially old or disabled people. Electronically controlled air suspension systems are commonly used incommercial vehicles to enhance ride comfort and improve handling stability. This paper focuses on thevehicle height adjustment process in actively controlled air suspension systems. A non-linear mathematicalmodel for adjusting vehicle height is developed by integrating vehicle dynamics, suspension pneumatics,and the thermodynamic effects of compressible flow. A PID controller is proposed for accurate control ofvehicle height. Effectiveness and performance of the proposed controller are verified by simulations.
