MONITORING DEVICE FOR BRAKE CONTROL DEVICE

WIPO Patent Application WO/2021/199174

A1

A monitoring device (100) for a brake control device comprises an acquisition unit (101) that acquires: information of an AC pressure sensor that detects the pressure in an AC command chamber provided to a brake control device (10) that controls the braking of a vehicle; information of a supply valve operation detection sensor that is provided between the AC command chamber and an air supply tank provided to the vehicle, to detect the operation of a supply valve for allowing or stopping the supply of the compressed air in the air supply tank to the AC command chamber; and information of an exhaust valve operation detection sensor provided on a flow path connecting the AC command chamber and the outside air, to detect the operation of the exhaust valve for releasing to the outside air, or stopping, the compressed air in the AC command chamber. The monitoring device also comprises a determination unit (103) that determines an abnormality of the brake control device on the basis of the information of the AC pressure sensor, the information of the supply valve operation detection sensor, and the information of the exhaust vale operation detection sensor.
