Abstract
An improvement is provided for use in a wheeled vehicle having anti-skid circuitry associated with the wheels thereof. Fundamentally, the invention comprises a comparator connected to the anti-skid circuitry which products an output signal when anti-skid signals exceed a particular level for a predetermined period of time. The output of the comparator is operative for removing the application of the anti-skid control circuit from the anti-skid valves and for applying in its place a rudimentary anti-skid control circuit comprising a multivibrator of predetermined duty cycle. Thus, under all conditions, braking effort remains with the vehicle operator but under certain conditions is modulated at a predetermined rate by the multivibrator. Provisions are also made for returning the anti-skid system to normal operation in conjunction with the brake system when the output of the anti-skid system drops below the aforesaid particular level.
