Abstract: A brake control system which limits the operation of the braking forces applied to the tires, to the non-slip portion of the tire brake force and wheel velocity characteristic curve, i.e., the front or positive slope side of the characteristic Mu/slip curve; and thereby, minimizes both tire and brake wear. In particular, two embodiments of the invention are disclosed. All of which contain three aspects: a basic deceleration control circuit; a large deviation control circuit; and an energy balance system. The basic deceleration control circuit produces an average deceleration by summing the decelerations from all of the wheels, through a filtered differentiation of the wheel speed, and dividing it by the number of wheels. The average deceleration is then compared to the pilot selected deceleration rate for Dry, Wet, or Icy conditions and an error signal is generated. This error signal is then applied to a hysteresis circuit which outputs a constant level positive or negative signal.
