Zusammenfassung:	To reduce power consumption and control a hydraulic supply device when a voltage of a power source drops during driving assist control in a brake system for a vehicle.SOLUTION: In a brake system for a vehicle, when a voltage of a power source drops during driving assist control, a current supplied to a solenoid of at least one electromagnetic valve among a plurality of electromagnetic valves included in a hydraulic pressure supply device is set to 0 from a state of being larger than 0. Thereby, it is possible to reduce power consumption and to control the hydraulic supply device. Further, since control of the hydraulic pressure supply device becomes possible, a hydraulic brake can be operated without a driver's operating a brake operating member, and the vehicle can be stopped.SELECTED DRAWING: Figure 6 【課題】車両用ブレーキシステムにおいて、運転支援制御中に電源の電圧が低下した場合に、電力消費量の低減を図り、液圧供給装置の制御を可能とすることである。【解決手段】車両用ブレーキシステムにおいて、運転支援制御中に電源の電圧が低下した場合には、液圧供給装置に含まれる複数の電磁弁のうちの少なくとも１つの電磁弁のソレノイドへの供給電流が０より大きい状態から０とされる。それにより、電力消費量を低減することが可能となり、液圧供給装置の制御を行うことが可能となる。また、液圧供給装置の制御が可能となるため、運転者がブレーキ操作部材の操作を行わなくても、液圧ブレーキを作動させることができ、車両を停止させることができる。【選択図】図６
