Abstract
An anti-skid brake control system which includes a method and apparatus for anti-skid brake control of the vehicle utilizing a first and second electromagnetic valves that controls operation of the at least one rear wheel and at least one rear brake of the vehicle which includes the steps of registering a first predetermined rear wheel rotational velocity standard and a predetermined rear wheel receleration rate upon braking of the vehicle, registering an actual rear wheel deceleration rate of the vehicle, establishing a predetermined velocity differential for operation of the first electromagnetic valve, establishing a second predetermined rear wheel rotational velocity standard, calculating a time period for changing from the first velocity standard to the second velocity standard, comparing the predetermined deceleration rate with the actual deceleration rate, comparing the predetermined velocity differential with the difference between the first and second velocity standards when the actual deceleration rate is less than the predetermined deceleration rate, energizing the first electromagnetic valve when the difference between the first and second velocity standards is equal to…
