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 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 an 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 at least one first air spring of the air spring arrangement and into the intermediate store;
• or,
• b) into the intermediate store;
• and,
• wherein the compensation volume comprises the at least one first air spring and the intermediate store comprises a second air spring of the plurality of air springs, and compressed air is discharged in a chronologically consecutive manner individually into the first air spring and subsequently into the second air spring.

A pneumatic system for a vehicle comprising:

• a compressed air supply and an air spring arrangement having a plurality of air springs and being pneumatically connected to the compressed air supply;
• the pneumatic system having a controller for controlling the compressed air supply and the air spring arrangement and being configured to carry out a method for operating the pneumatic system;
• in the method:
• an air dryer and/or an 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 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 an 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 the at least one first air spring of the air spring arrangement and into the intermediate store, wherein the intermediate store comprises the compressor and/or a connecting volume wherein the connecting volume has a pneumatic return flow line connecting the gallery to the compressor via a return flow valve.
