To provide a brake force control device for a vehicle that is able to prevent, without changing the design of the vehicle significantly, yaw resonance caused when braking is performed during traveling at an extremely low speed with an appropriate rotational speed of a liquid pressure pump.SOLUTION: A vehicle M includes a brake liquid pressure circuit 42 having a liquid pressure line for two systems that is capable of supplying a brake liquid pressure for each of front and rear wheels 6fl,6rr and 6fr,6rl arranged in a diagonal direction and capable of supplying an independent brake liquid pressure to each of the wheels. In the vehicle M, when the vehicle M is braked during traveling at a speed equal to or lower than a set vehicle speed Vth, BK_ECU13 executes distribution control for brake liquid pressure so that a front and rear distribution ratio of a brake force caused to generate in each of the wheels 6fl, 6fr, 6rl, 6rr is equal to a distribution ratio at which each of yaw moments generated in the vehicle M by braking is offset by the front and rear wheels 6fl, 6rr and 6fr,6rl arranged in the diagonal direction.SELECTED DRAWING: Figure 7
【課題】車体の大幅な設計変更を伴うことなく、適正な液圧ポンプの回転数にて、極低速での走行中に制動を行った際のヨー共振を抑制することができる車両の制動力制御装置を提供する。【解決手段】対角方向に配置された前後の車輪6fl,6rr及び6fr,6rl毎にブレーキ液圧を供給可能な2系統の液圧ラインを有し、且つ、前記各車輪に対してそれぞれ独立したブレーキ液圧を供給可能なブレーキ液圧回路42を備えた車両Mにおいて、設定車速以Vth下での走行中に車両Mを制動するとき、BK_ECU13は、各車輪6fl,6fr,6rl,6rrに発生させる制動力の前後配分比が、前記対角方向に配置された前記前後の車輪6fl,6rr及び6fr,6rlが制動によって車両Mにそれぞれ発生させるヨーモーメントを相殺させる配分比となるようにブレーキ液圧の配分制御を行う。【選択図】図7
