Antiskid brake control system affording acceleration control of a skidding wheel running on a low adhesion roadway

摘要

A vehicle antiskid brake control system in which a low threshold acceleration signal is formed in addition to the normal acceleration signal to withhold the reapplication of brake pressure an extended duration following a wheel skid correction to allow sufficient time for an accelerating wheel to reach substantial synchronous speed before braking is resumed when running on a roadway affording such a poor adhesion characteristic as to preclude attainment of a normal rate of wheel acceleration. On a roadway affording a good adhesion characteristic the low threshold acceleration signal is automatically prevented from influencing the antiskid system and the reapplication of brake pressure is instead influenced according to the normal acceleration signal.
