To provide a vehicular braking control device capable of compensating internal leakage of a fluid pump and improving pressure control accuracy in the vehicular braking control device in which increase control of braking fluid pressure is performed by the fluid pump driven by an electric motor.SOLUTION: A braking control device moves braking fluid between a reservoir and a wheel cylinder via a fluid pump driven by an electric motor to control wheel cylinder hydraulic pressure. The braking control device includes: an operation amount sensor for detecting braking operation amount; a hydraulic pressure sensor for detecting braking fluid pressure; a rotation angle sensor for detecting a rotation angle of the electric motor; and a controller for controlling the electric motor in accordance with the operation amount, the braking fluid pressure and target conduction amount calculated based on the rotation angle. The controller calculates a leakage rotation signal for compensating internal leakage of the fluid pump on the basis of the braking fluid pressure, and calculates the target conduction amount on the basis of the leakage rotation signal.SELECTED DRAWING: Figure 3

    【課題】 電気モータ駆動の流体ポンプによって制動液圧が増加調整される車両の制動制御装置において、流体ポンプの内部漏れが補償され、調圧精度が向上され得るものを提供する。【解決手段】 制動制御装置は、リザーバとホイールシリンダとの間で、電気モータによって駆動される流体ポンプを介して制動液を移動し、ホイールシリンダ液圧を調整する。制動制御装置には、制動操作量を検出する操作量センサと、制動液圧を検出する液圧センサと、電気モータの回転角を検出する回転角センサと、操作量、制動液圧、及び、回転角に基づいて演算された目標通電量に応じて電気モータを制御するコントローラと、を備える。コントローラは、制動液圧に基づいて流体ポンプの内部漏れを補償する漏れ回転信号を演算し、この漏れ回転信号に基づいて目標通電量を演算する。【選択図】 図3
