Pneumatic suspension is increasingly used in many cars. Control of a car body level is the main function of the pneumatic suspension. The experimental determination of the pneumatic spring characteristics suitable for the design and modeling of the car level control system is presented. The characteristics of the pneumatic spring are determined, that determine the quality of the control system. The effect of temperature changes inside the pneumatic spring is experimentally determined due to heat exchange on air pressure and vertical force during alignment of the car body. In addition, through modeling is evaluated by changing the level of the car body due to the impact of heat transfer. An original method of controlling the lifting and lowering of the vehicle body is proposed. The method is based on the energy balance and is the basis for reducing the number of strokes of the electropneumatic valve. The change in the level of the body due to the temperature effect is leveled due to the indirect consideration of this effect using the pressure sensor in the cylinder.
