<p><P>PROBLEM TO BE SOLVED: To accurately determine the replacing timing of a drying agent for removing moisture of compressed air discharged from an air compressor. <P>SOLUTION: The compressed air supplying device for the vehicle includes: an air dryer provided in a discharge line of the air compressor to remove foreign matter such as moisture contained in the compressed air; an exhaust valve provided in the air dryer; a solenoid valve which gives pneumatic pressure for control to the exhaust valve through a control line; an ECU which performs regeneration control of the drying agent in the air dryer by opening the solenoid valve at a predetermined time, thereby giving the pneumatic pressure to the exhaust valve to open the exhaust valve; and a humidity detection sensor provided on the downstream of the drying agent. When a humidity level detected by the sensor shows a humidity level of a preset threshold value or more, the ECU opens the exhaust valve through the solenoid valve regardless of the predetermined time to regenerate the drying agent. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
