PROBLEM TO BE SOLVED: To provide a brake control device of a vehicle having "a pressure mechanism driven by an electric motor" and "pressure adjusting means (fluid pressure modulator)" in which the electric motor is small-sized, and the responsiveness on an increase in brake fluid pressure is excellent.SOLUTION: Pressure adjusting means (MJR) is interposed in the middle of a first fluid passage (H1) that connects a pressure mechanism (KAK) and a wheel cylinder (WC). A second fluid passage (H2) that connects the pressure mechanism (KAK) and the wheel cylinder (WC) is provided without passing through the pressure adjusting means (MJR). Opening/closing means (VPR and SNT) are provided that selectively achieve a first state in which only the first fluid passage (H1) is communicated of the first and second fluid passages (H1 and H2) and a second state in which at least the second fluid passage (H2) is communicated of the first and second fluid passages (H1 and H2). The opening/closing means (VPR and SNT) are controlled according to an operational state of a vehicle.SELECTED DRAWING: Figure 1 【課題】「電気モータによって駆動される加圧機構」と「調圧手段（液圧モジュレータ）」とを備えた車両の制動制御装置であって、電気モータが小型であり、且つ、制動液圧の上昇に関する応答性が良好なものを提供すること。【解決手段】加圧機構（ＫＡＫ）とホイールシリンダ（ＷＣ）とを接続する第１の流体経路（Ｈ１）の途中に、調圧手段（ＭＪＲ）が介装される。調圧手段（ＭＪＲ）を経由せずに、加圧機構（ＫＡＫ）とホイールシリンダ（ＷＣ）とを接続する第２の流体経路（Ｈ２）が備えられる。第１、第２の流体経路（Ｈ１、Ｈ２）のうち第１の流体経路（Ｈ１）のみが連通する第１状態と、第１、第２の流体経路（Ｈ１、Ｈ２）のうち少なくとも第２の流体経路（Ｈ２）が連通する第２状態と、を選択的に実現する開閉手段（ＶＰＲ、ＳＮＴ）が備えられる。車両の運転状態に応じて開閉手段（ＶＰＲ、ＳＮＴ）が制御される。【選択図】図１
