By analyzing the modeling characteristic of ground and front-end impact areas, the modeling control strategy is proposed with regard to ventilation cover plate, engine hood, engine hood leading edge, fender and radiator grille, front bumper. The Riveting point support area concept is presented accordingly. Furthermore, the optimal position relationship of bumper modeling support area is obtained using the ADMAD under a given stiffness of bumper components. The result indicates that the optimized modeling can control the manipulation easily and helps to improve performance of driver assistance.
