PROBLEM TO BE SOLVED: To suppress in advance reduction in brake feeling due to a sudden change of a brake force even if substitution from a regenerative brake force into a fluid pressure brake force is performed when operating stabilization control during regenerative braking.SOLUTION: An electrically-driven vehicular brake device 11 comprises: a liquid pressure brake part which generates a liquid pressure brake force by a liquid pressure brake mechanism 24FL to 24RR provided on an electric automobile V; a regenerative brake part which generates a regenerative brake force by a third electric motor 92 provided on the electric automobile V; and a cooperative control part which sets distribution of respective brake forces by the liquid pressure brake part and the regenerative brake part, and performs cooperative control of each brake force by use of the set magnitude and distribution of the brake force. The cooperative control part reduces a degree, to which a magnitude of a liquid pressure brake force which is alternatively applied in the case that a request for alternation from the regenerative brake force into the liquid pressure brake force is generated by operation of stabilization control is weakened, compared with a degree in the case that a request for alternation is generated due to a factor other than operation of stabilization control.SELECTED DRAWING: Figure 3

    【課題】回生制動中の安定化制御の作動時に、回生制動力から液圧制動力への代替が行われるケースであっても、制動力の急変による制動フィーリングの低下を未然に抑止する。【解決手段】電動車両用制動装置11は、電気自動車Vに備わる液圧制動機構24FL〜24RRによって液圧制動力を発生させる液圧制動部と、電気自動車Vに備わる第3電動機92によって回生制動力を発生させる回生制動部と、液圧制動部及び回生制動部によるそれぞれの制動力の配分を設定すると共に、当該設定した制動力の大きさと配分を用いてそれぞれの制動力の協調制御を行う協調制御部と、を備える。協調制御部は、安定化制御の作動によって回生制動力から液圧制動力への代替要求が生じた場合に代替適用される液圧制動力の大きさを弱める度合いを、安定化制御の作動以外の要因によって代替要求が生じた場合のそれと比べて小さくする。【選択図】図3
