摘要： The object of the present invention is to provide a vehicle brake system capable of appropriately setting an upper limit value of hydraulic pressure of a by-wire brake during stopping of a vehicle in accordance with conditions. When the vehicle is stopped, a maximum allowable drive voltage calculation unit sets a maximum allowable drive voltage to V2, and sets a brake pressure generated by a motor to P2. When the vehicle is stopped, if a duration time of stopping of the vehicle or a duration time of generation of the brake pressure exceeds a reference value, the maximum allowable drive voltage calculation unit sets the maximum allowable drive voltage to V3, and sets the brake pressure generated by the motor to P3 which is lower than P2.
