A braking force control apparatus adapted to generate a braking force, which is larger than that generated in a regular case, when a predetermined braking operation is carried out, this apparatus aiming at preventing the occurrence of an unnecessarily large sensible deceleration during a low-speed travel of a vehicle. ECU (10) is adapted to judge whether or not an emergency braking operation has been executed on the basis of a master cylinder pressure (Pmc) and its rate of change (dPmc). When a judgement that an emergency braking operation has been carried out is given, a wheel cylinder pressure (Pwc) is quickly increased by supplying an accumulator pressure to the wheel cylinder. When a vehicle speed exceeds a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is speedily increased (116, 118) by a braking assist regular control operation. When the vehicle speed is not higher than a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is slowly increased (116, 120) by a braking assist starting special control operation. |
