To secure travel stability on a low μ road in consideration of the friction coefficient of the surface of a road on which the vehicle travels in deceleration, while appropriately regenerating deceleration energy.SOLUTION: A vehicular brake force control apparatus includes: a regenerative brake device for providing at least either of a front wheel and a rear wheel with regenerative brake force; a hydraulic brake device for providing a wheel with hydraulic brake force; and a control part for controlling the regenerative brake device and the hydraulic brake device. The control part includes: coordination control means for executing control so that at least regenerative brake force is generated as brake force exerted to a wheel, in the case of required deceleration being less than a threshold, and so that the generative brake force and hydraulic brake force are generated and so that a ratio of the hydraulic brake force is increased as the required deceleration increases, in the case of the required deceleration being equal to or higher than the threshold; and variation means for changing a magnitude of the threshold in accordance with the friction coefficient of the road surface on which the vehicle travels. Further, in the case of the friction coefficient of the road surface being lower than a given value, the variation means sets the threshold at lower value than in the case of the friction coefficient being equal to or higher than the given value.SELECTED DRAWING: Figure 5

    【課題】減速走行中の路面抵抗を考慮して、減速エネルギーを適切に回生しつつ、低μ路での走行安定性を確保すること。【解決手段】前輪および後輪のうちの少なくともどちらか一方に回生制動力を付与する回生ブレーキ装置と、車輪に油圧制動力を付与する油圧ブレーキ装置と、回生ブレーキ装置と油圧ブレーキ装置とを制御する制御部と、を備える車両の制動力制御装置であって、制御部は、要求減速度が閾値未満の場合には、車輪に付与される制動力として、少なくとも回生制動力を発生させ、要求減速度が閾値以上の場合には、回生制動力および油圧制動力を発生させるとともに要求減速度が大きくなるほど油圧制動力の割合が大きくなるように制御する協調制御手段と、走行中の路面抵抗に応じて閾値の大きさを変更する可変手段と、を有し、可変手段は、路面抵抗が所定値よりも低い場合には、路面抵抗が所定値以上の場合に比べて、閾値を低い値に設定する。【選択図】図5
