To provide a brake control device for controlling a fore-and-aft distribution ratio of brake force when a vehicle travels on a downward slope.SOLUTION: A brake control device 10 comprises a slip amount acquisition part for acquiring a slip amount of rear side wheels in a travel direction of a vehicle 90 of front wheels FL, FR and rear wheels RL, RR of the vehicle 90. The brake control device 10 has a fore-and-aft distribution ratio derivation part. The fore-and-aft distribution ratio derivation part executes fore-and-aft ratio adjusting processing for allocating brake force of the vehicle 90 to front wheel brake force and rear wheel brake force. The brake control device 10 has a control part for controlling brake force applied to each of the wheels FL, FR, RL, RR on the basis of a result of the fore-and-aft ratio adjusting processing. The fore-and-aft distribution ratio derivation part increases a ratio of the rear wheel brake force when the vehicle 90 travels on a downward slope. In addition, the fore-and-aft distribution ratio derivation part reduces further an increment of the ratio of the rear wheel brake force as a slip amount of the rear wheels RL, RR is larger.SELECTED DRAWING: Figure 1 【課題】車両が降坂路を走行する場合における制動力の前後配分比を制御する制動制御装置を提案する。【解決手段】制動制御装置１０は、車両９０の前輪ＦＬ，ＦＲおよび後輪ＲＬ，ＲＲのうち車両９０の進行方向に対して後方側の車輪のスリップ量を取得するスリップ量取得部を備えている。制動制御装置１０は、前後配分比導出部を備えている。前後配分比導出部は、車両９０の制動力を、前輪制動力と後輪制動力とに割り当てる前後比率調整処理を実行する。制動制御装置１０は、前後比率調整処理の結果に基づいて各車輪ＦＬ，ＦＲ，ＲＬ，ＲＲに付与する制動力を制御する制御部を備えている。前後配分比導出部は、車両９０が降坂路を前進しているとき、後輪制動力の比率を増大させる。さらに、前後配分比導出部は、後輪ＲＬ，ＲＲのスリップ量が大きいほど、後輪制動力の比率の増大量を小さくする。【選択図】図１
