ABSTRACT:
A brake force control apparatus performs both a brake assist control and an antilock brake control without interference therebetween. A master cylinder generates a brake fluid pressure corresponding to a magnitude of a brake operation. A pump has an inlet port and an outlet port, the inlet port being communicable with the master cylinder. An inlet control valve controls communication between the master cylinder and the inlet port of the pump. A wheel cylinder is communicable with each of the master cylinder and the outlet port of the pump. A supplementary reservoir is communicable with each of the wheel cylinder and the inlet port of the pump. The brake assist control is performed, when the emergency brake operation is performed by the driver, by opening the inlet control valve and actuating the pump. The antilock brake control is performed by controlling communication between said wheel cylinder and each of the master cylinder, the outlet port of the pump and the supplementary reservoir and actuating the pump. The inlet control valve is opened when both the brake assist control and the antilock brake control are performed concurrently.
