To reflect a changed operation speed in brake force when an operation speed has changed during a braking operation on a brake control device of a vehicle.SOLUTION: A brake control device 10 includes an operation acquisition unit 11 for acquiring an operation quantity and an operation speed of a brake operation member. The brake control device 10 includes an intermediate braking force derivation unit 21 for executing processing to derive intermediate braking force for each control cycle on the basis of the operation quantity. The brake control device 10 includes an operation speed gain derivation unit 25 for executing processing to derive an operation speed gain for each control cycle. The operation speed gain derivation unit 25 derives the operation speed gain more largely as the operation speed is faster. The brake control device 10 includes an adjusting unit 26 for executing processing to derive target braking force for each control cycle. The adjusting unit 26 derives the target braking force by adding a value obtained by multiplying a difference between a value this time and a value last time of the intermediate braking force by the operation speed gain to the value this time of the intermediate braking force.SELECTED DRAWING: Figure 2 【課題】車両の制動制御装置に関して、制動操作中に操作速度が変わった場合に変化した操作速度を制動力に反映させる。【解決手段】制動制御装置１０は、制動操作部材の操作量および操作速度を取得する操作取得部１１を備える。制動制御装置１０は、操作量に基づいて中間制動力を導出する処理を制御サイクル毎に実行する中間制動力導出部２１を備えている。制動制御装置１０は、操作速度ゲインを導出する処理を制御サイクル毎に実行する操作速度ゲイン導出部２５を備えている。操作速度ゲイン導出部２５は、操作速度が速いほど操作速度ゲインを大きく導出する。制動制御装置１０は、目標制動力を導出する処理を制御サイクル毎に実行する調整部２６を備えている。調整部２６は、中間制動力の今回の値と前回の値との差分に操作速度ゲインを乗算した値を中間制動力の今回の値に加算して目標制動力として導出する。【選択図】図２
