Abstract
A signal processing circuit provides control signals suitable for controlling the application of braking pressure in a fluid-control brake actuating mechanism. An input signal whose amplitude is proportional to wheel speed is differentiated to yield a signal proportional to acceleration and deceleration. A first output signal is generated when a predetermined deceleration threshold is exceeded. A second output signal is generated when both a deceleration and a velocity threshold are simultaneously exceeded. The second output signal is maintained until the velocity signal exceeds a variable reference threshold which varies with acceleration alone during acceleration.
