Claim Text:
1. A brake control device for a vehicle having a semi-brake-by-wire system, comprising: 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; a fluid pressure receiving structure that receives 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; a second switching valve disposed in a branch fluid passage connecting the master cylinder and the fluid pressure receiving structure; and a brake controller operable to open the first switching valve and the second switching valve to be at open states and close the first switching valve and the second switching valve to be at closed states, wherein, at system startup before the depression operation of the brake pedal, the first switching valve is at the closed state and the second switching valve is at the open state, wherein, at system non-startup/failure, the first switching valve is at the open state and the second switching valve is at the closed state, wherein, when the system is started after the depression operation of the brake pedal;
