To provide a brake control device of a vehicle capable of reducing possibility that deceleration of the vehicle due to an automatic brake function of ACC may exceed the prescribed limit value over prolonged period.SOLUTION: A brake control device of a vehicle comprises: a target brake torque setting parts (91, 101) which set target brake torque (T_out) on the basis of indication brake torque (T_req_in) which is set on the basis of target inter-vehicle distance between an own vehicle and a preceding vehicle; and control parts (93, 103) which control braking force of the vehicle on the basis of the target brake torque (T_out). The target brake torque setting parts (91, 101) set limit brake torque (T_lim) of a value smaller than the indication brake torque (T_req_in) to the target brake torque (T_out) when deceleration (Ax) of the own vehicle exceeds a prescribed limit value (Ax_lim).SELECTED DRAWING: Figure 5
【課題】ACCの自動ブレーキ機能による車両の減速度が長時間に亘って所定の制限値を超えるおそれを低減可能な車両の制動制御装置を提供する。【解決手段】車両の制動制御装置は、自車両と先行車両との目標車間距離に基づいて設定される指示制動トルク(T_req_in)に基づいて目標制動トルク(T_out)を設定する目標制動トルク設定部(91,101)と、目標制動トルク(T_out)に基づいて車両の制動力を制御する制御部(93,103)と、を備え、目標制動トルク設定部(91,101)は、自車両の減速度(Ax)が所定の制限値(Ax_lim)を超えたときに、指示制動トルク(T_req_in)よりも小さい値の制限制動トルク(T_lim)を目標制動トルク(T_out)に設定する。【選択図】図5
