To provide a pneumatic pressure control device for coping with an abnormality, which is easily retrofitted to even an existing vehicle, a pneumatic circuit and a brake control system.SOLUTION: A pressure control module 20 includes: a pneumatic circuit 22 that has a first port P1 connected to an air tank of a vehicle, a second port P2 connected to a brake valve outputting a pneumatic pressure signal when a braking operation is performed and a third port P3 connected to a brake mechanism applying braking force to a wheel on the basis of the pneumatic pressure signal and that enables switching between a first communication state for communicating air from the second port P2 to the third port P3 and a second communication state for communicating air from the first port P1 to the third port P3; and a sub ECU 32 that switches the pneumatic circuit 22 from the first communication state to the second communication state on the basis of an abnormal signal indicating an abnormality of a driver.SELECTED DRAWING: Figure 9

    【課題】既存車両にも後付けが容易である異常時対応用の空気圧制御装置、空気圧回路及びブレーキ制御システムを提供する。【解決手段】圧力制御モジュール20は、車両のエアタンクに接続する第1ポートP1、ブレーキ操作が行われた場合に空気圧信号を出力するブレーキバルブに接続する第2ポートP2、空気圧信号に基づき車輪に制動力を加えるブレーキ機構に接続する第3ポートP3を有し、第2ポートP2から第3ポートP3に空気を連通する第1連通状態と、第1ポートP1から第3ポートP3に空気を連通する第2連通状態とを切り替える空気圧回路22と、運転者の異常を示す異常信号に基づいて空気圧回路22を第1連通状態から第2連通状態に切り替えるサブECU32とを備える。【選択図】図9
