To provide a vehicular braking device that can suppress decrease in reserved electric energy of an auxiliary electric power source while allowing an occupant to early recognize a failure of a main electric power source.SOLUTION: The vehicular braking device comprises; an electric brake booster 43 that can brake a vehicle by driving a motor 32; a main electric power source 11 that can supply electric power to the electric brake booster 43; a capacitor 21 that can supply electric power to the electric brake booster 43; an ECU 5 that can control electric power to be supplied to the electric brake booster 43; and an electric power state detecting part 53 that can detect whether function of the main electric power source 11 deteriorates or stops. The ECU 5 sets target electric power supply amounts E to the electric brake booster 43 corresponding to target deceleration D for the vehicle, and corrects the target electric power supply amounts E to decrease the amounts when the electric power state detecting part 53 detects that the function of the main electric power source 11 deteriorates or stops.SELECTED DRAWING: Figure 5

    【課題】乗員による主電源失陥の早期認識を図りつつ補助電源の保留電力量の減少を抑制することができる車両用制動装置を提供する。【解決手段】モータ32の駆動により車両を制動可能な電動ブレーキブースタ43と、この電動ブレーキブースタ43に電力を供給可能な主電源11と、電動ブレーキブースタ43に電力を供給可能なキャパシタ21と、電動ブレーキブースタ43に供給する電力を制御可能なECU5と、主電源11の機能低下又は停止を検出可能な電源状態検出部53を有し、ECU5は、車両の目標減速度Dに対応した電動ブレーキブースタ43への目標電力供給量Eを設定すると共に、電源状態検出部53により主電源11の機能低下又は停止が検出されたとき、目標電力供給量Eを減少方向に補正している。【選択図】 図5
