To reduce possibility that a vehicle starts moving contrary to intention of a driver due to heat loosening or pedaling force loosening.SOLUTION: A braking force control apparatus 10 includes: a fluid pressure generation mechanism 70 which generates fluid pressure correlated with required braking force corresponding to a braking request, as required fluid pressure, when the braking request is made; a braking mechanism 80 which is arranged at each wheel, includes a rotation member 86 rotating along with each wheel and a braking member 88 which can contact the rotation member 86, and applies braking force depending on the required fluid pressure to each wheel by pressing the braking member 88 against the rotating rotary member 86 due to the required fluid pressure; fluid pressure control means for controlling the fluid pressure generation mechanism 70; and vehicle state specifying means for specifying whether a vehicle state is in a running state or a stopped state. While the required fluid pressure is generated and when a vehicle state to be specified shifts from the running state to the stopped state at a first time point, the fluid pressure control means performs stop-time boost control to boost the required fluid pressure after the first time point.SELECTED DRAWING: Figure 4A
【課題】 熱緩み又は踏力緩みに起因して運転者の意図に反して車両が動き出してしまう可能性を低減する。【解決手段】 制動力制御装置10は、制動要求があった場合に当該制動要求に応じた要求制動力に相関した液圧を要求液圧として発生させる液圧発生機構70と、各車輪に設けられ、各車輪とともに回転する回転部材86と、回転部材86に接触可能な制動部材88を含み、要求液圧により制動部材88が回転中の回転部材86に押し付けられることにより当該要求液圧に依存した制動力を各車輪に付与する制動機構80と、液圧発生機構70を制御する液圧制御手段と、車両の車両状態が走行状態にあるか停止状態にあるかを特定する車両状態特定手段を備える。液圧制御手段は、要求液圧が発生している状態で、特定される車両状態が第1時点において走行状態から停止状態に遷移した場合、第1時点以降の要求液圧を嵩上げする停止時嵩上げ制御を実行する。【選択図】 図4A
