Abstract:

For vehicle AFS and DYC coordination control problem,an integrated control algorithm based on model predictive control is proposed in this paper.The algorithm adopts hierarchical integrated control structure.The model predictive controller is designed and quadric programming method is used for tire force allocation.The simulation is used to verify the algorithm.The result shows that the algorithm can enhance the vehicle stability and is feasible.The tire force allocation by quadratic programming method with regard to a single wheel brake force allocation method can extend stability control range more.

Key words: vehicle engineering, integrated control, model predictive control, AFS, DYC, tire force allocation
