Abstract: For enhancing the vehicle stability in the extreme conditions, the vehicle horizontal integrated control of longitudinal and lateral movement ant the overall integrated control of longitudinal, lateral and vertical improvement were studied based on the model predictive control theory. The hierarchical integrated control structure was determined. The steering/braking model predictive controller and active suspension controller were disigned. The singlewheel braking force allocation method was used. It achieves the steering/braking horizontal integrated control  and the steering/braking/suspension overall integrated control. The simulation test was used to verify the algorithm. The result shows that the integrated control can enhance the vehicle stability and active safety effectively in the extreme conditions.

Key words: vehicle chassis, integrated control, model predictive control, the extreme conditions, stability
