Title:
AIR SUPPLY SYSTEM AND METHOD FOR CONTROLLING AIR SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/078068
Kind Code:
A1
Abstract:
Provided are: an air supply system in which a circuit for engaging and releasing a parking brake can also be used as a circuit for emergency purposes; and a method for controlling the air supply system. The air supply system is provided with: an air supply-exhaust channel 88 through which air is supplied to and discharged from a fifth load C25 that is a parking brake circuit; and a fifth protection valve 81 and a direction switching valve 82 that are connected to the air supply-exhaust channel 88, to an air supply channel 18 through which air is supplied from a compressor 4, and to the fifth load C25. The direction switching valve 82 is switchable between a supply position, at which the parking brake is released by allowing air to be supplied to the fifth load C25 from the air supply channel 18 when a power conducting state is set by a second ECU 16, and an exhaust position, at which the parking brake is engaged by allowing air to be discharged from the fifth load C25 via the air supply-exhaust channel 88 when a non-conducting state is caused during emergency or a non-conducting state is set by the second ECU 16 during a time of normal operation.
