Abstract
Control of vehicle body tilting when a railway vehicle travels along a curve includes: detecting a pressure of compressed air in an air tank; driving a compressor that supplies compressed air to the tank when detecting a pressure drop in the tank to or below a first threshold level Pin association with introduction of compressed air into air springs; and limiting the amount of compressed air to be introduced from the tank into the springs to a level equal to or lower than the amount of compressed air to be supplied from the compressor to the tank while continuing the introduction from the tank into the springs. This ensures that the tank pressure is maintained at a level equal to or higher than a minimum level required for braking actuation of the railway vehicle to have ride comfort when traveling along a curve and without causing braking trouble.
