Abstract: A period timer for use in an adaptive braking system determines when wheel speed falls below a reference speed and when wheel speed subsequently exceeds a second, higher, reference speed. A capacitor is charged to a voltage inversely proportional to wheel speed. If the capacitor voltage exceeds a reference voltage proportional to the reference speed a one-shot generates an output which is fed back to lower the reference voltage.

Abstract: An adaptive braking system in which the speed of each wheel on an axle is independently sensed but the braking pressure of both axle wheels is controlled during adaptive braking by a single brake pressure modulator. Performance information from the wheel having the higher speed is used to determine when brake pressure should be reduced. Performance information from the wheel having the lower speed is used to determine when the brake pressure should be subsequently increased. If the ratio of the speed of the low speed wheel with respect to the speed of the high speed wheel drops below a predetermined level, the wheel having the higher speed controls adaptive braking.
