An anti-skid brake control system for monitoring variation of wheel slippage and whereby detects APPLICATION mode of the anti-skid brake control system and for detecting HOLD mode of the anti-skid brake control. The system comprises a period of time where the operational mode is maintained at HOLD mode condition. When the period to maintain the HOLD mode becomes longer than a predetermined period, than the system set smaller rate for increasing the braking pressure in the subsequent APPLICATION mode.

An anti-skid brake control system for controlling a braking pressure for maintaining a wheel slippage in the vicinity of a predetermined optimum level said anti-skid control system comprising: a braking circuit connecting a pressurized fluid source to a wheel cylinder for each of said front and rear

An anti-skid brake control system for controlling a braking pressure for maintaining a wheel slippage in the vicinity of a predetermined optimum level said anti-skid control system comprising: a braking circuit connecting a pressurized fluid source to a wheel cylinder for each of said front and rear wheels for building up braking pressure in the latter; a pressure control valve means, disposed in said braking circuit, for controlling braking pressure in said wheel cylinder, said pressure control valve means operable for increasing braking pressure in said wheel cylinder in a first mode, decreasing braking pressure in said wheel cylinder in a second mode, and to hold the braking pressure in said wheel cylinder constant in a third mode; first sensor for monitoring rotation speed of associated one of the front and rear wheels for producing a wheel speed indicative signal; second means for deriving a wheel slippage on the basis of said wheel speed indicative signal and producing a wheel slippage data; control means for producing a first control signal for controlling operation mode of said pressure control valve means for switching operation mode between said first, second mode and third mode in order to maintain wheel slippage in the vicinity of said predetermined optimum value, said control means measuring a period in which said pressure control valve means is maintained at said third mode subsequently of said first mode operation so that increasing rate of braking pressure is varied according to said period.
