To provide a brake control device in which variation in pedal feel characteristics of a brake is suppressed.SOLUTION: A brake control device, in a preferable embodiment, comprises: a fluid passage part which connects a cylinder of a fluid pressure generator for generating a brake fluid pressure by an operator's brake operation, and plural brake devices; a blocking part which is located in the fluid passage part, and blocks transmission of a brake fluid pressure between the fluid pressure generator and at least one brake device among the plural brake devices; a fluid pressure source which generates a fluid pressure in the fluid passage part between the blocking part and at least one brake device independently from the fluid pressure generator; and an electronic control unit. When release of the brake operation by the operator is recognized in the state that the fluid passage part is blocked by the blocking part and a brake fluid pressure is applied to the brake device by the fluid pressure source, the electronic control unit determines a communication state between a pressure chamber and a reservoir of the fluid pressure generator on the basis of information concerning a position of a piston of the fluid pressure generator, and after the pressure chamber and the reservoir are communicated with each other, controls the blocking part, thereby communicating the fluid passage part.SELECTED DRAWING: Figure 3
【課題】 ブレーキのペダルフィール特性のばらつきを抑止したブレーキ制御装置を提供すること。【解決手段】 本発明によるブレーキ制御装置は、その好ましい態様において、運転者のブレーキ操作によってブレーキ液圧を発生させる液圧発生装置のシリンダと複数のブレーキ装置とを接続するための液路部と、この液路部に配置され、液圧発生装置と複数のブレーキ装置内の少なくとも1つのブレーキ装置との間のブレーキ液圧の伝達を遮断する遮断部と、遮断部と少なくとも1つのブレーキ装置との間の液路部に液圧発生装置とは独立して液圧を発生させる液圧源と、遮断部により液路部が遮断されて液圧源によりブレーキ装置にブレーキ液圧が付与されている状態において運転者によるブレーキ操作の解除を認識した場合に、液圧発生装置のピストンの位置に関する情報に基づいて液圧発生装置の圧力室とリザーバとの間の連通状態を判定し、圧力室とリザーバが連通した以降に遮断部を制御して液路部を連通させる電子制御ユニットとを備える。【選択図】図3
