A VEHICLE INCLUDING COMPRESSED AIR CONSUMING DEVICES AND A METHOD OF OPERATING THE SAME

WIPO Patent Application WO2006071170

A8

A vehicle (15), such as a lorry or a bus, includes compressed air consuming devices (13) and a power driven compressor (10) to deliver compressed air to at least one storage tank (11, 12). A control device (14) controls the operation of the compressor so as to maintain the air pressure in the tank at a desired pressure level sufficient to operate the air consuming devices, such as a braking system and a suspension system, when needed. The air pressure is usually maintained substantially at a predetermined first elevated level or value. However, based on signals from position identification means (17, 18), such as a global navigation system or other external or internal position identification sources the control device controls the operation of the compressor (10) so as to change the pressure of the air in the storage tank (11,12) to a predetermined second elevated level or value substantially different from said first level or value in response to receiving from the position identification means an indication to the effect that the vehicle (15) is approaching or has arrived at one (16,19) of a plurality of predetermined positions and/or positions fulfilling predetermined criteria.
