To provide a vehicular braking device that when electric power to be supplied to a brake bi-wire system runs short, enables an auxiliary electric power source to supply electric power to the system to provide optimum braking force.SOLUTION: In a vehicular braking device which comprises: electric brake means that can brake a vehicle by driving a motor by brake operation performed by an occupant; a main electric power source that can supply electric power to the electric brake means; auxiliary electric power supply units comprising a plurality of power storage means that can supply electric power to the electric brake means; and control means that when required electric power by the electric brake means is larger than electric power that the main electric power source can supply, makes the auxiliary electric power supply unit to supply electric power to the electric brake means, together with the main electric power source or in a first connection mode in which at least one of the auxiliary electric power supply units is solely used in stead of the main electric power source, the control means, when a predetermined condition is satisfied, switches the auxiliary electric power supply unit from the first connection mode into a second connection mode in which the plurality of power storage means are connected in series and used.SELECTED DRAWING: Figure 7

    【課題】ブレーキバイワイヤシステムに供給される電力が不足する場合に、補助電源からの電力供給を可能にして最適な制動力を得ることができる車両用制動装置を提供すること。【解決手段】乗員のブレーキ操作によりモータを駆動して車両を制動可能な電動ブレーキ手段と、この電動ブレーキ手段に電力を供給可能な主電源と、前記電動ブレーキ手段に電力を供給可能な複数の蓄電手段を備えた補助電源装置と、前記電動ブレーキ手段の必要電力が前記主電源の供給可能な電力より大きい場合に、前記主電源と共に又は前記主電源の代わりに前記補助電源装置の少なくとも1つを単独使用する第1の接続形態で前記補助電源装置から前記電動ブレーキ手段に電力を供給させる制御手段とを備えた車両用制動装置において、前記制御手段は、所定条件の成立時には前記補助電源装置を前記第1の接続形態から前記複数の蓄電手段を直列に接続して使用する第2の接続形態に切替える。【選択図】図7
