ABSTRACT:
A wheel-slip control system for a multiple truck vehicle having a speed sensor for producing signals representative of the velocity of each of the wheel axle units. A differentiator connected to each of the speed sensors for differentiating the velocity signals to obtain rate signals. A rate determining circuit for determining the most negative-going rate signals of each of the wheel axle units of each truck. A plurality of deceleration threshold and rate direction detectors and data processing logic to initiate a brake force reduction action on the truck experiencing a wheel slip, and a positive logical "OR" gate for sensing a polarity shift in the most negative rate signal to cause the data processing logic to reapply a braking action.
