PROBLEM TO BE SOLVED: To provide a slide control device and a slide controlling method by which an axle can be reliably recovered from a slide state even if sliding occurs in all axles of a railway vehicle.SOLUTION: A slide control device 10 (a speed conversion part 20, a limit speed calculation part 21, a reference axis speed determination part 22, a speed difference calculation part 23 and a slide judgement part 30) detects sliding of a wheel for every axle on the basis of rotational speed of each of plural axles of a railway vehicle. When sliding is detected in all axles of the railway vehicle, a brake force adjustment part 40 of the slide control device 10 reduces a brake force applied to a wheel of each axle only during a time sufficient for recovering at least one axle from the slide state.SELECTED DRAWING: Figure 3 【課題】鉄道車両の全ての車軸で滑走が発生しても、車軸を滑走状態から確実に復帰させることができる滑走制御装置及び滑走制御方法を提供する。【解決手段】滑走制御装置１０（速度換算部２０、限界速度算出部２１、基準軸速度決定部２２、速度差算出部２３及び滑走判定部３０）は、鉄道車両の複数の車軸各々の回転速度に基づいて、車輪の滑走を車軸毎に検出する。滑走制御装置１０のブレーキ力調整部４０は、鉄道車両の全ての車軸で滑走が検出されると、少なくとも１つの車軸が滑走状態から回復するのに十分な時間だけ、各車軸の車輪に加えるブレーキ力を小さくする。【選択図】図３
