Abstract
A skid control system which compares a current representative of wheel deceleration with an alterable reference current using an integrating comparator to control the brakes of a vehicle. The reference current has an initial value which represents a wheel deceleration indicative of an incipient skid condition and is increased to a substantially higher value after the current representative of wheel deceleration reaches the initial reference current value and is reduced to a very low value after a predetermined period of time. When the current representative of wheel deceleration exceeds the reference current by a predetermined degree as determined by the integrating comparator, the brakes are released. The brakes are reapplied after the current representative of wheel deceleration no longer exceeds the reference current at a time determined by the integrating comparator.
