Title:
VALVE DEVICE FOR BRAKE CONTROL
Document Type and Number:
Japanese Patent JPH06278593
Kind Code:
A
Abstract:

PURPOSE: To automatically switch either to a brake fluid pressure manipulated by a driver or to the brake fluid pressure based on an electric signal by providing a switching valve for selectively applying the brake fluid pressure generated by a linear control valve and the brake fluid pressure generated by a master cylinder to a wheel cylinder.

CONSTITUTION: When a driver steps on a, brake pedal 1, a linear control valve 51 regulates a high-pressure brake fluid accumulated at an accumulator 10 to a prescribed brake fluid pressure through a pressure regulating action based on a signal from a controller 14. The brake fluid pressure is applied to the linear control valve 51, a higher pressure side of a switching valve 52 is selected, and the brake fluid pressure is applied to a wheel cylinder 4A for braking. In the case not through stepping on the brake pedal 1 by the driver, for example, when excessive slip is caused at a wheel 4 at acceleration of a vehicle, the rotation state of the wheel 4 is detected by a wheel speed sensor 13, and a signal is sent to the controller 14.
