In this paper we present a sliding mode based vehicle control strategy, which includes antilock braking and antispin acceleration. This strategy uses the slip velocity as controlled variable instead of wheel slip. The sliding mode control is integrated with an adaptation process for the unknown and varying adhesion coefficient of the tire road interface. The proposed control method is verified through one-wheel simulation model with a “Magic formula” tire model. Simulations results show the effectiveness of this controller scheme.
