Abstract
[OBJECT] To provide a brake control apparatus and method for controlling the brake which is capable of preventing a fluctuation of a brake pedal stroke amount when switching a regenerative braking force to a hydraulic braking force. [MEANS TO SOLVE] A brake control apparatus has a stroke simulatorinto which a brake fluid that flows out of a master cylinder M/C by driver's braking operation is able to flow; a pipewhich connects the stroke simulatorand the master cylinder M/C; a gate-in valvewhich is set on the pipeand opens/closes the pipe; a pump P which pumps up the brake fluid flowing into the stroke simulatorfrom the master cylinder M/C and can increase a pressure of a wheel cylinder W/C that is provided for each wheel; an HUwhich increases the wheel cylinder pressure by the brake fluid flowing into the stroke simulatorand pumped up by the pump P, together with at least the gate-in valve; and a regenerative brake unit which is provided separately from the HUand produces a regenerative braking force for the wheel.
