To provide a high-performance brake control device capable of effectively reducing vehicle body vibrations generated during traveling on a road with steps and irregularities.SOLUTION: A brake control device includes: a travel environment estimation part to estimate travel environment from behaviors of a first wheel that is one of a plurality of wheels included in a vehicle; and a timing calculation part to calculate timing at which a second wheel different from the first wheel is affected by the travel environment on the basis of a vehicle speed. The brake control device controls braking of any one of the plurality of wheels on the basis of an estimation result in the travel environment estimation part and a calculation result in the timing calculation part.SELECTED DRAWING: Figure 5 【課題】段差や凹凸のある道路の走行時に発生する車体振動を効果的に抑制可能な高性能なブレーキ制御装置を提供する。【解決手段】車両に備えられる複数の車輪のいずれかである第１車輪の挙動から走行環境を推定する走行環境推定部と、前記第１車輪とは異なる第２車輪が前記走行環境の影響を受けるタイミングを車速に基づいて演算するタイミング演算部と、を備え、前記走行環境推定部の推定結果と前記タイミング演算部の演算結果に基づいて、前記複数の車輪のいずれかの制動を制御することを特徴とする。【選択図】 図５
