To reduce drive sound by driving a pump motor at a proper motor rotational speed.SOLUTION: A brake control device (10) includes: a brake control unit (12) for controlling an automatic brake for automatically decelerating own vehicle; a pump motor (21) for increasing a brake fluid pressure of the automatic brake at decelerating the own vehicle; and an inclination angle detection part (18) for detecting an inclination angle of a travelling road surface on which the own vehicle is positioned. The brake control unit controls a motor rotational speed of the pump motor so as to change the brake fluid pressure in accordance with the inclination angle of the travelling road surface.SELECTED DRAWING: Figure 1 【課題】ポンプモータを適切なモータ回転速度で駆動して駆動音を低減する。【解決手段】ブレーキ制御装置（１０）は、自車両を自動的に減速させるための自動ブレーキを制御するブレーキ制御部（１２）と、自車両の減速時に自動ブレーキのブレーキ液圧を増圧するポンプモータ（２１）と、自車両が位置している走行路面の傾斜角度を検出する傾斜角度検出部（１８）と、を備えている。ブレーキ制御部は、走行路面の傾斜角度に応じたブレーキ液圧になるようにポンプモータのモータ回転速度を制御する。【選択図】図１
