Abstract
A vehicle brake system () includes a first control device () and a second control device () that respectively include a master controller (), a first sub-controller (), and a second sub-controller () that are connected to one another. Each of the master controller (), the first sub-controller (), and the second sub-controller () includes a braking force calculation unit that calculates braking force of electric brakes (to), and a determination unit that compares braking force calculation results of the controllers to determine whether itself is normal. The determination unit includes an output block section that blocks, when the determination unit determines that any one of the controllers is not normal, an output of the controller that is determined to be not normal.
