Abstract:
A brake control apparatus for a vehicle, comprising:a brake fluid pressure generating device which has a generating source to generate a first brake fluid pressure to apply braking force to a vehicle;a wheel braking force generating device which generates a braking force at a wheel in response to a brake fluid pressure applied thereto;a conduit system which communicates said brake fluid pressure generating device with said wheel braking force generating device; anda pressure amplifying device which divides said conduit system into a first conduit subsystem and a second conduit subsystem, said first conduit subsystem conveying brake fluid between said brake fluid pressure generating device and said pressure amplifying device at said first brake fluid pressure and said second conduit subsystem conveying brake fluid between said pressure amplifying device and said wheel braking force generating device at a second brake fluid pressure when said first brake fluid pressure is generated by said brake fluid pressure generating device, said pressure amplifying device including a pump and being constructed and arranged to move brake fluid from said first conduit subsystem to said second conduit subsystem so that said second brake fluid pressure is greater than said first brake fluid pressure,wherein said pressure-amplifying device is provided with a holding device to hold a differential pressure between said second brake fluid pressure at said second conduit subsystem and said first brake fluid pressure at said first conduit subsystem, andwherein said second conduit subsystem is provided with an antiskid controlling system, comprising:a pressure adjusting device for increasing or decreasing brake fluid pressure applied to said wheel braking force generating device to realize an optimal slip state of a wheel;a reservoir to accumulate brake fluid discharged from the wheel braking force generating device during operation of said pressure adjusting device; anda discharging device to discharge brake fluid accumulated in said reservoir.
