Abstract
A skid control system for use in connection with controlling the application of the brakes on a two-wheeled vehicle which includes a sensor device for sensing the velocity of wheel rotation, a triple integration circuit connected to the sensor for producing an analog signal which is proportional to the wheel velocity and a proportioning circuit connected to the triple integration circuit. The output of the proportioning circuit is fed to a hysteresis and low speed cut-off circuit, and a ramp generator circuit, the outputs of the two above noted circuits being fed to the input of a comparator circuit which compares the wheel velocity with a simulated vehicle velocity signal generated by the ramp generator circuit. The output of the comparator is utilized to control a brake application valve associated with the brake system. The brake control system also includes a plurality of fail-safe systems which continuously monitor various other circuits within the brake control system and produces an output signal when a fault condition is sensed.
