Based on the vehicle plane motion model, an integrated control strategy of Active Front Steering (AFS) and Direct Yaw Control (DYC) based on Multi-Input Multi-Output (MIMO) structure is proposed. Based on the hierarchical structure of chassis integrated control system, the integrated controller based on phase plane theory and the integrated controller based on MIMO structure are built respectively. The designed integrated controller is verified by simulation under different driving conditions. The results show that the proposed integrated control strategy based on multi-input multi-output structure has better control effect under different working conditions, effectively ensures the vehicle state to follow the desired value, and thus significantly improves the handling stability of the vehicle.
