BRAKE CONTROL DEVICE OF VEHICLE

PROBLEM TO BE SOLVED: To suppress a rotation angle difference of electric motors when fluid passages are made to communicate with each other, in a brake control device having the two system fluid passages which are pressure-regulated by the electric motors.SOLUTION: A brake control device comprises: a first pressure-regulation mechanism for pressurizing a brake fluid of a first system fluid passage by a first electric motor; a second pressure-regulation mechanism for pressurizing a brake fluid of a second system fluid passage by a second electric motor; a communication valve which is interposed in a fluid passage for connecting the first and second system fluid passages, and selectively performs communication and blocking; a controller for controlling the first and second electric motors on the basis of first and second target electricity-carrying amounts; and first and second rotation angle sensors for detecting rotation angles of the first and second electric motors. Then, when the communication valve is in a communication state, and a rotation angle difference of the first and second electric motors is larger than a prescribed value, the controller performs at least either of "a decrease of a target electricity-carrying amount corresponding to a larger rotation angle" and "an increase of a target electricity-carrying amount corresponding to a smaller rotation angle".SELECTED DRAWING: Figure 5 【課題】 電気モータにて調圧される２系統流体路を備えた制動制御装置において、流体路が連通される場合に電気モータの回転角差を抑制する。【解決手段】 制動制御装置は、第１系統流体路の制動液を第１電気モータにて加圧する第１調圧機構と、第２系統流体路の制動液を第２電気モータにて加圧する第２調圧機構と、第１、第２系統流体路を接続する流体路に介装され連通と遮断とを選択的に実現する連通弁と、第１、第２目標通電量に基づいて第１、第２電気モータを制御するコントローラと、第１、第２電気モータの回転角を検出する第１、第２回転角センサと、を備える。そして、コントローラは、連通弁が連通状態であって、且つ、第１、第２電気モータの回転角差が所定値よりも大きい場合に、「回転角が大きい方に対応する目標通電量の減少」、及び、「回転角が小さい方に対応する目標通電量の増加」のうちで、少なくとも何れか一方を実行する。【選択図】 図５
