To provide a fluid pressure control unit that can estimate stroke amounts of an armature of an electromagnetic valve with good accuracy.SOLUTION: In a fluid pressure control unit according to the present invention, a control device includes an estimating part that estimates stroke amounts (Δx) of an armature (312) of an electromagnetic valve (31). The estimating part estimates the stroke amounts (Δx) on the basis of amounts of current values reduced at the time when the current values reduce temporality in the course in which the current values of currents flowing into winding (314) increase to target current values when starting to apply currents to the winding (314) of the electromagnetic valve (31).SELECTED DRAWING: Figure 3

    【課題】本発明は、電磁弁のアーマチュアのストローク量を精度良く推定することができる液圧制御ユニットを得るものである。【解決手段】本発明に係る液圧制御ユニットでは、制御装置は、電磁弁(31)のアーマチュア(312)のストローク量(Δx)を推定する推定部を含み、推定部は、電磁弁(31)の巻線(314)への電流の印加開始時において巻線(314)に流れる電流の電流値が目標電流値に向けて上昇する過程で電流値が一時的に下降する際の電流値の下降量に基づいて、ストローク量(Δx)を推定する。【選択図】図3
