Abstract
A vehicle traction control system is actuated when driven wheel slip (S) exceeds a predetermined slip threshold (T) to reduce the amount of driven wheel slip (S) by reducing the driven wheel speed. The traction control system also monitors vehicle deceleration. Upon detecting that the vehicle is decelerating and that the vehicle deceleration has exceed a deceleration threshold, the traction control system determines that the vehicle has encountered a deformable surface such as mud or deep snow. Upon detecting entry onto a deformable surface, the slip threshold (T) is linearly increased over a period of time to increase the driven wheel speed and thereby allow the wheels to churn through the deformable surface.
