PROBLEM TO BE SOLVED: To provide a vehicular brake system capable of reducing accuracy deterioration of brake force due to expansion of a brake fluid.SOLUTION: A vehicular brake system 10 comprises: an input side hydraulic system Pin; an output side hydraulic system Pout; first and second shut-off valves 60b, 60a for shutting off circulation of a brake fluid between the input side hydraulic system Pin and the output side hydraulic system Pout by valve opening; first and second out valves 128, 130 for allowing the brake fluid to flow into a reservoir device 132 by valve opening; and control means 150 for generating brake fluid pressure corresponding to a control input of a brake pedal 12 in a motor cylinder device 16 of the output side hydraulic system Pout. The control means 150 opens at least either the first and second shut-off valves 60b, 60a or the first and second out valves 128, 130 when output characteristics of the brake fluid pressure, which is output from the motor cylinder device 16, vary from basic characteristics.SELECTED DRAWING: Figure 1

    【課題】ブレーキ液の膨張による制動力の精度低下を軽減可能な車両用ブレーキシステムを提供することを課題とする。【解決手段】入力側液圧系統Pinと、出力側液圧系統Poutと、閉弁して入力側液圧系統Pinと出力側液圧系統Poutの間のブレーキ液の流通を遮断する第1、第2遮断弁60b,60aと、開弁してブレーキ液をリザーバ装置132に流入させる第1、第2アウトバルブ128,130と、ブレーキペダル12の操作量に応じたブレーキ液圧を出力側液圧系統Poutのモータシリンダ装置16で発生させる制御手段150と、を有する車両用ブレーキシステム10とする。そして、制御手段150は、モータシリンダ装置16から出力するブレーキ液圧の出力特性が基本特性から変化したときに、第1、第2遮断弁60b,60aと第1、第2アウトバルブ128,130の少なくとも一方を開弁する。【選択図】図1
