Summary: | 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 |
