Patent ID: 8550571

Claim:
A brake control apparatus that supplies a brake fluid to a wheel cylinder via a fluid pressure circuit to thereby supply a fluid pressure to the wheel cylinder and apply a braking force to a wheel through the fluid pressure, comprising: a fluid pressure source that is provided in the fluid pressure circuit to supply a fluid pressure to the wheel cylinder; a fluid pressure adjusting valve that is open during stoppage of energization, and has an opening degree thereof adjusted through energization control to adjust the fluid pressure supplied to the wheel cylinder; a communication valve that is provided in series with the fluid pressure adjusting valve, is closed during stoppage of energization to hold the fluid pressure supplied to the wheel cylinder, and is opened through energization; a fluid pressure sensor that detects the fluid pressure; and a control portion that controls driving of the fluid pressure source and energization of the fluid pressure adjusting valve and the communication valve, wherein the control portion controls fluid pressure adjustment achieved by driving the fluid pressure source to supply the fluid pressure to the wheel cylinder, opening the communication valve, and adjusting the opening degree of the fluid pressure adjusting valve to adjust the fluid pressure, and fluid pressure holding achieved by closing the communication valve, opening the fluid pressure adjusting valve, and holding the fluid pressure by means of the communication valve, and wherein the control portion closes the fluid pressure adjusting valve, then closes the communication valve, and subsequently opens the fluid pressure adjusting valve to hold the fluid pressure by means of the communication valve.
