Method for operating a pneumatic system, and pneumatic system including compressed air supply installation and air spring installation

A method for operating a pneumatic system having a compressed air supply and an air spring arrangement, pneumatically connected to the compressed air supply, the pneumatic system being for a vehicle, wherein:

• the compressed air supply has a pneumatic main line and an air dryer in the pneumatic main line, and the pneumatic main line has a compressor port to a compressor, and a compressed air supply port to an air distributor module, wherein:
• the air spring arrangement has a plurality of air springs, pneumatically connected via a gallery of the air spring arrangement, and wherein:
• the pneumatic system has a controller for controlling the compressed air supply and the air spring arrangement, and wherein, in the method, the air dryer and/or the air distributor module represents an overpressure volume, wherein:
• the overpressure volume initially has a pressure greater than a pressure in a remaining portion of the compressed air supply with the remaining portion being defined by a compensation volume;
• the pneumatic spring system further having at least one first air spring and an intermediate store or the intermediate store;
• wherein the method comprises:
• discharging compressed air from the overpressure volume into the compensation volume, accompanied by a reduction in the pressure in the overpressure volume with the accompanying reduction in the pressure in the air dryer and/or reduction in the pressure in the air distributor module;
• wherein compressed air is discharged into one of the following:
• a) into the first air spring of the air spring arrangement and into the intermediate store;
• or,
• b) into the intermediate store.
