VEHICLE BRAKE DEVICE AND METHOD OF CONTROLLING THE SAME

摘要

An object of the invention is to prevent abnormal noise from being generated when the pressure of brake fluid supplied to a brake caliper is reduced. A vehicle brake device includes first and second hydraulic brakes generating a hydraulic brake force and a regenerative brake generating a regenerative brake force and divides a braking force into the hydraulic brake force and the regenerative brake force. The vehicle brake device includes a regulating valve that is provided between the first and second hydraulic brakes and continuously regulates the flow rate of brake fluid flowing to the second hydraulic brake from the first hydraulic brake, and a pressure reducing valve that reduces the pressure of the brake fluid supplied to the second hydraulic brake. An opening of the regulating valve is continuously increased and the pressure reducing valve is opened, when the hydraulic brake force of the first hydraulic brake is reduced.
