A new air supply / exhaust control system was developed for pneumatic suspension of railway vehicle. This system which equalizes unbalanced inner pressure of air spring and horizontalizes the vehicle floor when the vehicle is slowed or stopped. It counters such defects experienced in the conventional leveling valve (LV) system as large unbalance of air spring inner pressure when stopping at distorted track of transient curve that might cause wheel unloading and decrease the derailment safety margin. The new control system is composed of solenoid valves, height and pressure sensors, clinometer and controller (CPU). Major control laws are (1) detect forced deflection of air spring caused by track distortion, (2) equalize the air spring height distortion when running, (3) horizontalize vehicle when slowed or stopped, and (4) equalize air spring pressure unbalance. These functions are implemented in a computer program.
