Traction control algorithm for vehicle operation upon deformable road surfaces

摘要: A vehicle traction control system is actuated when driven wheel slip (S1) exceeds a predetermined threshold (Ts) to reduce the amount of by reducing speed. The also monitors deceleration. Upon detecting that decelerating and deceleration has exceed threshold, determines encountered deformable surface such as mud or deep snow. entry onto surface, linearly increased over period time increase speed thereby allow wheels churn through surface.
