In this work, a driving assistance system (DAS) sharing the control of a vehicle with a human driver is proposed. The cooperation degree between the DAS and the human driver is in the center of this work with the aims of reducing conflict between them. A lane keeping driver model is added to the road-vehicle one in order to achieve this goal. Fuzzy Takagi-Sugeno (T-S) optimal controller is driven considering a varying vehicle longitudinal velocity. The system is evaluated regarding both the human-machine interaction point of view in hazardous situation and the lane keeping performance. Firstly, numerical simulations carried out in Matlab/Simulink are illustrated, and after, the proposed DAS is tested on the LAMIH-SHERPA dynamic simulator with a human driver. The obtained results show the effectiveness of the proposed approach.
