Abstract
A VSA device (24), which controls vehicle behavior by individually controlling the pressure of brake fluid supplied from a slave cylinder (23) to a wheel cylinder (16, 17; 20, 23), is provided with: an accumulator (62) which can be connected to the wheel cylinder and the slave cylinder (23); an out-valve (60, 61) disposed on a fluid path between the wheel cylinder and the accumulator (62); a check valve (63) that allows only flow of brake fluid from the accumulator (62) to the slave cylinder (23); and a regulator valve (54) disposed on a fluid path between the wheel cylinder and a path between the check valve (63) and the slave cylinder (23). Brake fluid is discharged from the accumulator (62) to the slave cylinder (23) by reducing the driving force of an electric motor (32) of the slave cylinder (23), thereby rendering a special pump unnecessary and making it possible to reduce the weight, cost, and component count.
