Tire blowout will cause serious safety problems and impair the vehicle stability.Many studies in the literature proposed the stability controller for the tire blowout,but these studies focused on the traditional internal combustion engine vehicle.This paper proposes a control allocation method based sliding mode control(SMC)to optimally allocate the steering and driving actuators for four-wheel independent steering(4WIS)and four-wheel independent driving(4WID)electric vehicle after a tire blowout.The driving ac-tuators are allocated by SMC to achieve the desired longitudinal velocity and yaw rate and the steering actuators are used to achieve the desired lateral velocity.Simulation results have presented to validate the proposed control strategy.
