To provide a technique for realizing proper lowering control of the BC pressure in consideration of delay characteristics related to lowering of the BC pressure.SOLUTION: A pneumatic braking skid control device 1 calculates a tangential force coefficient μ on the basis of the BC pressure and the wheel rotational acceleration α and performs skid control of lowering the BC pressure to allow re-adhesion when detecting the occurrence of a skid. In the pneumatic braking skid control device 1, a target decision unit 23 decides a target tangential force coefficient μT for allowing re-adhesion when the occurrence of the skid is detected, a BC pressure lowering execution control unit 25 executes and controls lowering to the BC pressure corresponding to the target tangential force coefficient μT, and a complementation control unit 30 determines whether or not to perform additional lowering of the BC pressure on the basis of a difference between the target tangential force coefficient μT and the tangential force coefficient μ immediately after lowering is executed.SELECTED DRAWING: Figure 1

    【課題】BC圧の引き下げに係る遅れ特性を考慮したBC圧の適切な引き下げ制御を実現するための技術を提供すること。【解決手段】空制滑走制御装置1は、BC圧及び車輪回転加速度αに基づいて接線力係数μを算出し、滑走の発生を検知した場合に、BC圧を引き下げて再粘着させる滑走制御を行う。この空制滑走制御装置1において、目標決定部23は、滑走の発生検知がなされた場合に再粘着させるための目標接線力係数μTを決定し、BC圧引き下げ実行制御部25は、目標接線力係数μTに対応するBC圧への引き下げを実行制御する。そして、補完制御部30は、引き下げが実行された直後の接線力係数μと目標接線力係数μTとの差に基づいて、BC圧の追加引き下げを行うか否かを判定する。【選択図】図1
