An integrated air supply unit comprises a compressor housing, a pressure control unit (PCU) body, and a desiccant housing extending between the compressor housing and the PCU body. The desiccant housing defines a desiccant cavity holding a desiccant container for removing moisture from air passing therethrough. A piston is slidably disposed within a piston bore of the compressor housing. The PCU body defines a plurality of fluid passages with solenoid valves selectively controlling airflow therethrough. The integrated air supply unit may also comprise: a manifold, a discharge control valve, a compressor supplying pressurized air in a first pressurized air passage, a dryer configured to remove moisture from the pressurized air in the first pressurized air passage and to supply dried pressurized air in a second pressurized air passage, a supply control valve to control airflow between the second pressurized air passage and the manifold, and a piloted exhaust valve.

A method for controlling an air suspension system of a vehicle includes: a) determining a bellows pressure-time characteristic curve for air admission to and release from the bellows of one air spring or the bellows of a plurality of air springs, the characteristic curve being normalized with the value of a supply pressure in a reservoir for compressed air, b) sensor measurement of a current pressure in the spring bellows of the air springs as well as the current supply pressure immediately before air admission thereto or air release therefrom, c) determining, from the normalized characteristic curve, the opening duration for the associated shutoff valve using the ratio of the measured bellows pressure to the measured supply pressure and the ratio of the provided target pressure to the measured supply pressure, d) opening the associated shutoff valve for the determined opening duration in order to set the provided target pressure.

The first directional valve forms a primary valve, and the second forms a secondary valve. First and second air bellows associated with the valve system are fillable/bleedable depending on the switching state of the primary and secondary valves. The primary and secondary valves are controllable by a controller of the magnetic part. The controller is common to and acts upon both valves.
