| Abstract: | This paper deals with the integrated control of the active front steering(AFS) and the direct yam moment control(DYC) for steering-by-wire 4WID electric vehicles and proposes a hierarchical algorithm based on the model predictive control.Moreover,the corresponding model predictive controller is designed and a driving force allocation method based on the quadric programming is investigated.Finally,a simulation is carried out to verify the proposed algorithm.The results show that the proposed algorithm enables the vehicle to track the expected tra-jectory and improves the vehicle stability and active safety. |
