Even in the case that at least one braking force generating function fails, it is possible to secure a maximum braking force as well as suppressing a yaw moment generated on the basis of the failure as much as possible even at a time when whatever braking force is requested, A target braking force to a normal brake apparatus is calculated on the basis of a result of detection by a malfunction detecting portion, in such a manner that a total of braking forces generated in the brake apparatuses in respective wheels becomes as equal as possible to a requested braking force, at a time when a malfunction is generated in the brake apparatus or a braking force control portion.
