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.
