To provide a vehicular brake system capable of improving energy efficiency of a vehicle without delaying start of substitution control.SOLUTION: A brake system 10 comprises: a motor generator 21 causing a vehicle to generate regenerative brake force; a friction brake device 30 causing the vehicle to generate friction brake force; and a control device 40 controlling the motor generator 21 and the friction brake device 30 so that a total sum of the regenerative brake force and the friction brake force is a request brake force. In substitution controlling, the control device 40 increases reduction speed of the regenerative brake force as time elapses from reduction start of the regenerative brake force due to start of the substitution control.SELECTED DRAWING: Figure 1

    【課題】すり替え制御の開始を遅らせなくても車両のエネルギ効率を向上させることができる車両の制動システムを提供すること。【解決手段】制動システム10は、車両に回生制動力を発生させるモータジェネレータ21と、車両に摩擦制動力を発生させる摩擦制動装置30と、回生制動力と摩擦制動力との総和が要求制動力となるように、モータジェネレータ21及び摩擦制動装置30を制御する制御装置40とを備えている。制御装置40は、すり替え制御では、当該すり替え制御の開始による回生制動力の減少開始から時間が経過するほど回生制動力の減少速度を大きくする。【選択図】図1
