The B-pillar with TRB (Tailor Rolled Blank) is developed for weight reduction of car body. The reinforcements in the typical B PLR can be replaced by one TRB part which has continuous thickness changes. TRB thickness profile is modified for satisfying IIHS side impact test. The free fall tests have been carried out. The results show that the new B PLR with TRB is 15% lighter than typical structure and has equivalent crashworthiness.

FEM (Front End Module) is a module located between the front bumper and the BIW, and the Front Beam, Cooling module, H/Lamp, etc assembled in Carrier. In addition, with the recent development of electric vehicles and autonomous vehicles, the installation of electric parts such as Lidar, Radar, and Vess is increasing. Therefore, the FEM not only serves as a front crash member, but also plays a structural role in determining the cooling module layout and mounting various electrical components. Recently, various studies on the optimization of electric vehicle platforms have been conducted. In this study, the carrier structure was changed to develop the FEM structure for electric vehicles. (Add collision member, change cooling module mounting angle) Through this, while maintaining the existing carrier performance, new layouts such as improved collision performance, securing of trunk space, and tilting structure of the cooling module were presented.
