Abstract
A vehicle skid control braking system of the type that includes circuit components for generating a signal varying in accordance with braking conditions, such as vehicle speed, wheel speed and road surface conditions. The vehicle skid control braking system includes a ramp generator responsive to the signal generating circuitry, wherein the ramp generator has a charge storage device for storing a charge proportional to the varying signal, control circuitry having an output signal varying between first and second valves, and a discharge circuit for discharging the storage device at a controlled rate to a level determined by the varying of the output signal of the control circuitry from the first value to the second value. The ramp generator produces an output current that varies inversely with vehicle speed.
