Abstract
A brake control device for a vehicle has a master cylinder that converts an operating force of a brake pedal to a fluid pressure, a wheel cylinder installed in each wheel of the vehicle that generates a braking force by a fluid pressure introduced in each wheel, an introduction section that introduces the fluid pressure generated by the master cylinder, a first switching valve disposed in a fluid passage connecting the master cylinder and the wheel cylinder, and closes at system startup and opens at system non-startup/failure, a second switching valve disposed in a branch fluid passage connecting the master cylinder and the introduction section and opens at the system startup and closes at the system non-startup/failure, and a brake controller. When the system is started after the depression operation of the brake pedal, the brake controller closes the second switching valve.
