To provide a regenerative cooperation system which suppresses deterioration of a brake feeling and improves regenerative efficiency in substitution control.SOLUTION: A regenerative cooperation system comprises: master pistons 13c, 13d coupled to a brake pedal 11; an actuator 5 for sucking brake fluid in the master chambers 13a, 13b when increasing liquid pressure brake force; a control part 61 for starting substitution control for substituting the liquid pressure brake force for regenerative brake force as brake force applied to the wheels W when a vehicle speed of the vehicle becomes a prescribed start vehicle speed in braking; a correction part 63 for, when an operation determination part 62 determines that, the brake pedal 11 is in an operation state, setting a start vehicle speed of the substitution control to a normal start vehicle speed, and when the operation determination part 62 determines that the brake pedal 11 is not in the operation state, setting the start vehicle speed to a correction start vehicle speed which is slower than the normal start vehicle speed.SELECTED DRAWING: Figure 1

    【課題】ブレーキフィーリングの悪化を抑制しつつ、すり替え制御における回生効率を向上させることができる回生協調システムを提供する。【解決手段】本発明は、ブレーキペダル11に連結されたマスタピストン13c、13dと、液圧制動力を増大させるに際してマスタ室13a、13b内のブレーキ液を吸引するアクチュエータ5と、制動中に車両の車速が所定の開始車速になった場合に、車輪Wに付与する制動力を回生制動力から液圧制動力にすり替えるすり替え制御を開始する制御部61と、すり替え制御の開始車速を、操作判定部62によりブレーキペダル11が操作状態であると判定されている場合、通常開始車速に設定し、操作判定部62によりブレーキペダル11が非操作状態であると判定されている場合、通常開始車速より小さい補正開始車速に設定する補正部63と、を備える。【選択図】図1
