1. A traction control system for a vehicle comprising:

  • a plurality of wheel speed sensors adapted to sense the speed of associated vehicle wheels, said wheel speed sensors operative to generate wheel speed signals; and

    a controller electrically connected to said wheel speed sensors, said controller operative to monitor said wheel speed signals and to calculate a wheel slip for each of said driven wheels and a vehicle deceleration, said controller also operative upon a driven wheel slip exceeding a slip threshold to reduce said driven wheel slip below said slip threshold, said controller further operative while said driven wheel slip exceeds said slip threshold to monitor said vehicle deceleration and to generate a deformable surface signal upon said deceleration exceeding a predetermined deceleration threshold.
