    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.

    摘要： The present invention aims to reduce dragging of a brake and to use sufficiently and effectively a regenerative brake force by suppressing an influence of a reaction of an accumulator when a pressure decreasing valve is opened.
    There is provided a brake device for a vehicle, that includes at least a first hydraulic brake and a second hydraulic brake which produce hydraulic brake forces, and a regenerative brake which produces a regenerative brake force, and that performs a distribution of the hydraulic brake force and the regenerative brake force with respect to a driver request brake force, including: a first pressure increasing valve which can increase a pressure of brake fluid supplied to the first hydraulic brake; a first pressure decreasing valve which can decrease the pressure of the brake fluid supplied to the first hydraulic brake; a second pressure increasing valve which can increase a pressure of brake fluid supplied to the second hydraulic brake; and a second pressure decreasing valve which can decrease the pressure of the brake fluid supplied to the second hydraulic brake, wherein the first pressure decreasing valve and the second pressure decreasing valve communicate with an accumulator, and wherein while the driver request brake force is covered by only the regenerative brake force, the first pressure increasing valve and the first pressure decreasing valve are opened, and the second pressure increasing valve and the second pressure decreasing valve are closed.
