摘要： An object of the present invention is to provide a brake control apparatus including a backup brake, which brake control apparatus makes it possible both to ensure deceleration, and to attain vehicle running stability.
The present invention includes: a front-wheel-side braking mechanism 4 that includes a front-wheel-side electric hydraulic mechanism 6, and a hydraulic circuit system, and applies braking force to front wheels 2L, and 2R; a rear-wheel-side braking mechanism 5 that applies braking on a rear wheel side; a backup brake that is actuated in accordance with a switch to the hydraulic circuit system 15 when the front-wheel-side electric hydraulic mechanism 6 fails, and applies braking force to the front wheels 2R, and 2L; and a skid determination threshold setting section 43 that sets a skid determination threshold. When the backup brake is actuated, the skid determination threshold setting section 43 sets the skid determination threshold for the rear wheels 3L, and 3R on the basis of braking force information of the backup brake.
