Abstract
Trains of electrical pulses are produced at variable rates proportional to the vehicle and wheel speeds respectively and fed into a first and a second pulse counter, each producing its output upon counting of a predetermined number which is determined such that an optimum slip rate occurs when the outputs of these counters are produced at the same time. The output of these counters are utilized to operate and release an actuator which controls the flow of hydraulic pressure applied upon depression of a brake pedal to the wheels of a vehicle.
