Embodiment Construction
[0063] figure 1 Shown is a circuit diagram including a compressed air control device 2 according to the invention, with which, optionally with the aid of additional components of a compressed air supply system 4 with the compressed air control device 2 , the Compressed air control method. This compressed air supply system 4 additionally has a compressor 6 and an air drying device 8 .
[0064] The compressed air control unit 2 is controlled by an electronic control unit 10 . The compressed air control device 2 has, in particular, an electrically actuatable feed control valve 12 which can be switched electrically from the non-energized to the energized switching state by an electronic control unit 10 . In addition, the compressed air control device 2 has a so-called regulator or a pneumatically actuated discharge control valve 14 , which likewise can be switched between two switching states, but is pneumatically actuated. Finally, the compressed air control unit 2 also has a ...

The invention relates to a compressed air control device (2) and to a compressed air control method for controlling respective operating states of a compressor (6) and of an air drying device (8) in a vehicle. The compressed air control device (2) has a compressor control outlet (36), by means of which the compressed air control device can be pneumatically connected to a control inlet of the compressor (6) in order to pneumatically switch the operating state of the compressor (6). The compressed air control device (2) further comprises a system pressure inlet (28), by means of which the compressed air control device can be pneumatically connected to a system pressure line (21), which conducts a system pressure produced by the compressor (6). The compressed air control device (2) further comprises a ventilation control outlet (36), by means of which the compressed air control device can be pneumatically connected to a control inlet of the air drying device (8) in order to pneumatically switch the operating state of the air drying device (8). Finally, the compressed air control device (2) also comprises a pneumatically operable ventilation control valve (14), by means of which the system pressure inlet (21) can be pneumatically connected to the ventilation control outlet (36) depending on the system pressure in order to switch the operating state of the air drying device (8). According to the invention, an electrically operable supply control valve (12) is provided in the compressed air control device (2).; By means of the supply control valve, the system pressure inlet (28) can be pneumatically connected to the compressor control outlet (62) independently of the system pressure in order to switch the operating state of the compressor (6). Thus, energy-saving operation of a compressed air supply system (4) comprising the compressed air control device (2) and the air drying device (8) by means of a compressed air supply method containing the compressed air control method is possible.
Description
