PROBLEM TO BE SOLVED: To provide a brake control device which enables improvement of compression responsiveness of a wheel cylinder while inhibiting enlargement of an actuator or the like.SOLUTION: A brake control device includes: a pump 7 which causes a fluid pressure to be generated in a first oil passage 11 by a brake fluid supplied from a reservoir tank 4 to generate a fluid pressure in a wheel cylinder 8; and a stroke simulator 22 which includes a piston 220, which is configured to be actuated in a cylinder 22a in an axial direction by the brake fluid supplied from a master cylinder 5 and separates at least an interior part of the cylinder into two chambers (a positive pressure chamber R1 and a back pressure chamber R2), and generates operation reaction force resulting from a driver's brake operation by the piston being actuated; a second oil passage 12 provided between the positive pressure chamber (one chamber) of the stroke simulator 22 and the master cylinder; and a third oil passage 13 which is provided between the back pressure chamber (the other chamber) and the first oil passage and used to send the brake fluid flowing out from the back pressure chamber to the first oil passage.SELECTED DRAWING: Figure 1

    【課題】アクチュエータの大型化等を抑制しつつホイルシリンダの加圧応答性を向上することができるブレーキ制御装置を提供する。【解決手段】リザーバタンク4から供給されるブレーキ液により第1油路11に液圧を発生させてホイルシリンダ8に液圧を発生可能なポンプ7と、マスタシリンダ5から供給されるブレーキ液によりシリンダ22a内を軸方向に作動可能に構成され、少なくともシリンダ内を2室(正圧室R1と背圧室R2)に分離するピストン220を備え、ピストンが作動することで運転者のブレーキ操作に伴う操作反力を生成するストロークシミュレータ22と、ストロークシミュレータ22の正圧室(一方の室)とマスタシリンダとの間に設けられた第2油路12と、背圧室(他方の室)と第1油路との間に設けられ、背圧室から流出したブレーキ液を第1油路に送るための第3油路13とを備えた。【選択図】図1
