Abstract
In the brake control device, a wheel-cylinder hydraulic pressure (Pw) obtained by adding the linear-valve pressure difference to a master-cylinder hydraulic pressure (Pm) is applied to the wheel cylinder while the vehicle is running. When an operation of a brake pedal is started while the vehicle is running (t1), the driving of the hydraulic pump is started. Thereafter, when the vehicle is stopped (t2), the driving of the hydraulic pump is stopped. When the start of movement of the vehicle is detected during an operation of returning the brake pedal (t4) and an operation of re-depressing the brake pedal is detected (t5) in this state (specifically, while the vehicle is in a stopped state, the hydraulic pump is in a stopped state, and the brake pedal is being operated), the driving of the hydraulic pump is started (t5).
