Abstract

The system has a means for detecting differences of speed of wheels on a vehicle, a speed reference and apparatus to correct the power braking accordingly. There is a comparator-selector which transmits information on an instantaneous basis to a regulator which is associated with the highest speed wheel (at a given instant). There is a computer and logic unit receiving information and also controlling wheel efforts. The logic unit works on the basis of small intervals of time. The whole system is based on the application of mathematics to the known physical properties of wheel adhesion.
