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 a parking state detecting part 53 that can detect a parking state of the vehicle. The ECU 5 is provided with a charging control part 56 that charges electric power into the capacitor 21 and a charging start-timing setting part that sets timing of starting to charge electric power into the capacitor 21 to timing earlier than timing of starting the vehicle when the detected parking state by the parking state detecting part 53 is a specific parking state.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、車両の駐車状態を検出可能な駐車状態検出部53とを有し、ECU5に、キャパシタ21に電力を充電する充電制御部56と、駐車状態検出部53により検出された駐車状態が特定駐車状態の場合にはキャパシタ21への充電開始タイミングを車両始動時よりも早いタイミングに設定する充電開始タイミング設定部を設けている。【選択図】 図5
