  • Anti-skid brake control system which optimizes frequency of pressure build-up pulses
    Patent number: 5244258
    Abstract: A brake pressure controller increases the brake pressure in pulsed increments separated by pressure maintenance phases. During each maintenance phase, an evaluation circuit generates a stability criterion for each wheel which depends on the wheel acceleration and the slippage. If the criterion indicates that the wheel is stable, a pressure build-up pulse is generated. If the wheel is in dynamic transition, the pressure is maintained. If instability or limited stability is indicated, brake pressure is reduced. The system serves to maximize frequency of the build-up pulses for a stable running wheel.
