Abstract
A digital traction control system is disclosed for a motor vehicle having a plurality of driven wheels connected by a differential mechanism, characterized by the provision of a plurality of counters for counting pulses produced in accordance with the rotational velocities of the driven wheels, respectively, the counters being resettable when the count totals therein are within a given ratio. In the event that a driven wheel experiences a spin condition causing it to rotate at a higher rotational velocity than the other wheels, whereby the pulse count total of its associated counter exceeds the count total of the other counters outside the given ratio, a solenoid-operated brake is automatically activated to brake the faster wheel, thereby to transfer driving torque to the other driven wheel or wheels.
