COMPRESSED-AIR FEEDING DEVICE FOR VEHICLE, COMPRESSED-AIR FEEDING SYSTEM FOR VEHICLE, AND CONTROL METHOD FOR COMPRESSED-AIR FEEDING DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To detect a state of a desiccant for removing moisture in compressed air discharged from an air compressor to suitably reproduce the desiccant.SOLUTION: A compressed-air feeding device for vehicles comprises an air compressor mounted on the vehicle and feeding compressed air discharged from the air compressor to a load of the vehicle, and further comprises: an air dryer disposed in a discharging line of the air compressor to remove a foreign substance such as moisture contained in the compressed air; reproduction means for reproducing a desiccant in the air dryer under a prescribed reproduction condition; and a moisture sensor disposed downstream of the desiccant. In the compressed-air feeding device, the reproduction condition is optimized on the basis of detection result of the moisture sensor.
