Abstract
A brake system which can secure quietness in a passenger compartment is provided. A vehicle brake system 1 includes a brake assist device 2 which boosts a pressing force on a brake pedal 5 by drive of a motor 31, and an assist control unit 6 which controls the motor 31. The assist control unit 6 changes responsiveness of the motor 31 in accordance with a vehicle speed, and sets a dead zone amount and a filtering value to large values in a region with a low vehicle speed. Thereby, responsiveness of a boosting operation of the motor 31 to the operation of the brake pedal is made low, and a rotational variation and a vibration are prevented from occurring to the motor 31 by a minute variation of a detection signal of a stroke sensor 14 during low-speed traveling or stoppage of traveling.
