A vehicle anti-skid control device includes an inlet valve and an outlet valve which can each open and close, thereby selectively applying hydraulic brake pressure to a wheel of a vehicle, along brake lines connected thereto. An electronic control device applies electronic signals to selectively open and close the inlet and outlet valves. The waveform of the signals is configured to operate the inlet valve in such a way as to prevent sudden changes in the brake pressure.

Method and apparatus for anti-skid control

An anti-skid control device is provided that eliminates noise and vibration, provides better pedal responsiveness, and provides better anti-skid control. In the anti-skid control device 1, a pressure regulator valve 4 is positioned in the brake line between the master cylinder 12 and inlet valve 21, and the pressure differential between the input side and output side of the inlet valve 21 is minimized.
