ABSTRACT:
An anti-skid brake system for a wheeled vehicle including speed sensors for detecting each speed of road wheels of the vehicle and for producing an electric signal indicative of the detected speed of the road wheels, an electronic control apparatus arranged to be applied with the electric signal from the speed sensors for producing a control signal in accordance with conditions of a travel road of the vehicle in braking operation, and an electrically operated actuator arranged to be activated under control of the control apparatus for controlling a hydraulic braking pressure applied to each brake cylinder of the road wheels in response to the control signal, wherein an acceleration speed of the road wheels is calculated in response to the electric signal from the speed sensors, a stepped portion on the travel road is detected by determination of the fact that the detected speed of the road wheels becomes higher than a predetermined reference speed within a predetermined time immediately after activation of the actuator and that the calculated acceleration speed of the road wheels becomes smaller than a predetermined negative value and larger than a predetermined positive value within the predetermined time, and the actuator is deactivated upon detection of the stepped portion on the travel road.
